EASTERN IBERIAN CAVE USED FOR 24K YEARS:

Cova Dones (Cave of the Women), Spain. Internet image, public domain.

Finding caves occupied and decorated during the Paleolithic is no longer a unique phenomenon, neither is finding traces of Roman occupation in Iberia and Europe. Finding a cave that has both Paleolithic art and traces of Roman occupation is somewhat less common. Add to that, this cave is on the eastern side of the Iberian peninsula, not in the Franco-Cantabrian region where most of the decorated caves in Europe are found and we have something that is almost unique. This is Cova Dones, the Cave of the Women

The art in Cova Dones was discovered in 2021 and is being studied by a team of academics. (Ruiz-Redondo et al. 2023:1) “So far, we have identified more than 110 graphic units, including at least 19 zoomorphic representations, located in three different zones of the cave. Despite being deep inside the cave (the main decorated area is approximately 400m from the entrance), all zones, and the panels and figures they contain, are easily accessible without any climbing required. The depicted animals are seven horses, seven hinds (female red deer), two aurochs, a stag, and two indeterminate animals. The rest of the art consists of conventional signs (rectangles, meanders), several panels of ‘macaroni’ (‘flutings’ made with either fingers or tools dragged across a soft surface), isolated lines, and poorly preserved unidentified paintings. The variability and rarity of the technical features of the artworks are noteworthy because the assemblage includes different types of engravings and paintings.” (Ruiz-Redondo et al. 2023:2)

The cave possesses a wide variety of human made markings and images.  “The variability and rarity of the technical features of the artworks are noteworthy because the assemblage includes different types of engravings and paintings. The engravings comprise the classic single-trait outlines of figures, but also figures shaded by scraping the mondmilch (a type of limestone precipitate) on the surface of the walls. This technique is rare in Paleolithic cave art and previously unknown in eastern Iberia. The painting technique is no less surprising; motifs were created through the application of red clay on the walls, instead of the usual diluted ochre or manganese powder. This iron-rich clay is abundant on the floors of the cave. Examples of such technique are known in the Mediterranean area and beyond (e.g. Ardales, Bernifal, Higuerón, La Pasiega, Pileta, Rouffignac), but they are rare in all of these sites (except at La Baume Latrone). In Cova Dones the entire painted corpus (>80 graphic units) is made using this technique.” (Ruiz-Redondo et al. 2023:2-3) The variety mentioned above may suggest that the images were produced over quite a period of time by many different artists.

There are also a number of scratched claw marks of a scale that would match the claws of a cave bear, in one location scratched across some of the finger fluting. “Stylistic analysis of the figures points to a pre-Magdalenian age (>20 ka cal BP) and, considering the date for the extinction of the cave bear, we estimate that at least part of the rock art must be more than 24,000 years old.” (Ruiz-Redondo et al. 2023:4)

“While the project is still in its early stages, preliminary results reveal an enormous potential for research at the site and establish this assemblage as arguably the most important for the eastern Iberian coast. Its iconographic and technical features make it one of the few major Pleistocene decorated sites of eastern Iberia.” (Ruiz-Redondo et al. 2023:4) This decorated cave is far from done presenting researchers with surprises.

Along with the Paleolithic cave art this cave holds a large number of inscriptions in Latin carved into the walls. “Archaeologists recorded the inscriptions during a 2026 campaign at Cova de les Dones, near Millares in Valencia. Most date from the first and second centuries CE. The new finds raise the known number of Latin texts at the site from about 15 to at least 129. The inscriptions sit on the walls and ceilings of a chamber more than 200 meters underground. Researchers call the space the Roman Sanctuary. Their location and tight grouping point to a planned place of worship rather than a cave used for occasional religious visits. Five votive inscriptions refer to a goddess addressed as Domina, meaning ‘the Lady.’ Three also contain the word ‘MALACI,’ and unknown title or name linked to the goddess. Researchers are still working on its exact reading and meaning. The title might relate to water, and important feature of the underground setting.” (Radley 2026) Another possibility is that the word MALACI may be a millennia-old ‘Kilroy was here.’

And, along with the inscriptions in Latin were found a large number of artifacts including many spindle whorls which point to a focus on female activities or concerns. Other finds include rings and a coin featuring the emperor Hadrian. (Radley 2026)

It is always interesting when a discovery opens up a new area or field of inquiry, and Cova Dones has provided more than one.

RADIO CARBON DATING THE PAINTINGS OF FONT-DE-GAUME:

Students of rock art and cave painting have long lamented the difficulties of estimating dates. With carbon 14 dating you need an organic component in order to date the image, and if there is no black charcoal in the image the pigment cannot be dated. Some paints have organic binders which can be dated sometimes, but organic binders usually do not last as long as inorganic pigments.

One cave in France with Paleolithic cave art that we have wanted to date is Font-de-gaume. “Font-de-Gaume is one of many caves designated as a UNESCO World Heritage site in the Dordogne region of France. Because of the historical significance of the cave art, touching the walls of Font-de-Gaume is forbidden. The only exception is for collecting a sample to conduct radiocarbon dating, as the analytical technique intrinsically requires some physical material.” (Samuels 2026)

The cave of Font-de-Gaume in France has many paintings, but it has always been assumed that the black pigment was a manganese and/or iron mineral and, as such, could not be dated with radiocarbon dating. “Radiocarbon dating works by measuring carbon-14, a radioactive form of carbon that gradually disappears after an organism dies. Because charcoal is made from burned organic material, it can often be dated using this method. Mineral pigments, however, usually contain no carbon and therefore cannot be analyzed in the same way. Researchers had long believed that many black paintings in the region were made entirely from iron and manganese oxides. These naturally occurring minerals can produce dark pigments, but they do not contain the organic carbon needed for radiocarbon dating.” (CNRS 2026) A recent study, however, disproved this assumption.

In a recent study it was proven that there is indeed charcoal in some of the black paint in Font-de-Gaume. “To carry out this verification, the scientists examined the chemical composition of two black drawings, depicting a bison and a mask, using Raman microspectrometry and hyperspectral imaging . These noninvasive methods revealed traces of charcoal in the black pigments.” (Landurant  2026)

Knowing that a portion of the black paint provided a means for Carbon-14 dating, the researchers received permission to remove samples for testing. “Ina Reiche, a research chemist at the French National Center for Scientific Research led the team that removed tiny samples of charcoal for dating. They also added reflectance imaging spectroscopy (RIS) to their repertoire. The method essentially combines imaging and spectroscopy, and might be ‘even better with respect to what we did before,’ Reiche says. The scientists collected four tiny pigment samples one from the bison and three from the mask. The team then used accelerator mass spectrometry to determine the concentration of carbon-14 in each sample and calculated the ages. Three of the four samples date to the Paleolithic era, but the left eye of the mask was markedly younger. Reiche says that it’s clear the left eye contains younger carbon but impossible to know if it came from purposeful retouching, accidental contamination, or more recent graffiti.” (Samuels 2026) This newer date, however, is a sport and not relevant to our purposes.

After the collection and processing of the samples the results turned out to be truly exciting. “Collecting micro-samples was authorized on an exceptional basis for carbon 14 dating. Although this dating is challenging given the tiny amount of material, analyses confirmed a date in the Upper Paleolithic, slightly more recent than previously estimated: the bison was painted between 13,461 and 13,162 calBP, while different parts of the mask were painted between 8,993 and 8,590 calBP, 15,981 and 15,121 calBP, and between 15,297 and 14,246 calBP.” (Landurant 2026) This procedure opens up possibilities for other locations as well. Being able to identify carbon in black painted images will provide a powerful new tool in cave art analysis.

DAMAGE TO ROCK ART FROM POWER PLANT POLLUTION EMISSIONS:

From 2020 to 2026 a study was conducted at a location known as Murujuga, on the Burrup Peninsula and Dampier Archipelago in the Pilbara region of Western Australia. This fascinating study was an attempt to discern what, if any, damage to rock art was inflicted by the air pollution emitted from power plants and industrial enterprises.

Amy Stevens (2026) has written about the area and the importance of the abundant rock art found there, frequently citing K. A. Evans (2026). “Murujuga is a sacred cultural landscape of land and sea Country across the Burrup Peninsula and Dampier Archipelago, in Western Australia’s Pilbara region. It contains an estimated 1 million to 2 million petroglyphs, or rock engravings, that tell the story of the relationship between Ngarda-Ngarli Traditional Owners and this landscape over at least 50,000 years. These petroglyphs hold deep meaning for Ngarda-Ngarli, embodying cultural, spiritual, ancestral and environmental knowledge.” (Stevens 2026)

“In July 2025, the Murujuga Cultural Landscape was added to the UNESCO World Heritage List in recognition of its outstanding cultural and spiritual significance. This brought renewed attention to Murujuga, “commodities such as liquefied natural gas (LNG). Concerns have been raised that industrial pollution is degrading the rock art.” (Stevens 2026) As it is a site in the UNESCO World Heritage List, there is an international recognition of its importance to all people, and degradation of the rock art is then a concert to all people.

Indeed, this has been a concern for over a decade. A 2017 paper by John Black studied the color changes that the pollution might cause in the patina of the rock art panels, and did conclude that there was destruction beginning to show. “The art is under threat due to high concentration sof acidic and nitrate-rich pollution from nearby industrial complexes. Maintenance of the outer, rock or desert varnish, layer of therocks is essential for preservation of the art. An increase in acidity of rock surfaces through acid rain and organic acids from nitrate-stimulated microbial growth may alter the mineral composition, integrity and color of the rock varnish. This paper describes analyses of distilled water washings from rocks on Burrup Peninsula compared with rocks collected prior to industrialization. Acidity of rock surfaces has increased from near neutral to a pH just above 4. The increasing acidity has been associated with a logarithmic increase in solubilization of manganese (Mn) and iron (Fe) compounds from the rock surfaces. A theoretical evaluation using electrochemical equilibrium principles confirms that increasing acidity will increase the solubilization of Mn and Fe compounds. Removal of darker Mn and Fe mixed M(II)/M(III) compounds from the outer, rock varnish layer and the relative increase in ferrous oxide and illite/kaolin compounds will result in the rock surface layers becoming thinner, lighter, redder and more white/yellow over time. The impact on engraved surfaces would be expected to be greater because the rock varnish is thinner than on the non-engraved surface rock. Pollution from industry on Burrup Peninsula is likely to destroy the rock art over time.” (Black et al 2017) In other words, Black et al found that aerial pollution was degrading the patina on the rock surfaces, especially within the petroglyphs themselves.

Stevens (2026) reported on the third annual report of this monitoring program. In her article K. A. Evans stated “today we released the third annual peer-reviewed report of the Murujuga Rock Art Monitoring Program (MRAMP). This government-funded research effort doesn’t resolve every question – understanding a system as complex as Murujuga takes time. The research is undertaken by a team of more than 30 multidisciplinary researchers, and independently peer reviewed by a range of international experts. It is solely written by the researchers.” (Stevens 2026)

Stevens (2026) quoted from Evans report that “Earlier monitoring pointed to nitrogen dioxide, the most abundant air pollutant gas at Murujuga, as a possible cause. But our data at the time couldn’t clearly separate its effects from other air-borne pollutants, particularly sulfur dioxide.” (Stevens 2026)

Evans (2026) stated “This year’s results change that and the acid rain it can produce, as the most relevant factor. The chemistry behind this is well understood: sulfur dioxide reacts in the atmosphere or on the rock surface to form sulfuric acid. This can dissolve the manganese and iron oxide minerals that give the rock varnish its dark color, to create porosity. Several lines of evidence – atmospheric chemistry, rainfall pH and laboratory testing – now point to historic levels of sulphur dioxide from a range of industry and shipping.” (Evans 2026) Known as acid rain this will degrade the patina as well as the rock surface.

“Rock, rainfall, and dry deposition pH values argue against present-day acidification of rock surfaces and historically high rates of patina dissolution. However, the elevated porosity values proximal to heavy industry require explanation. Any such explanation must be placed in the context of this ancient landscape. The rocks of Murujuga weathered sub-aerially for thousands to tens of thousands or even hundreds of thousands of years, prior to the introduction of heavy industry from the 1960s onwards. As heavy industry evolved, the fluxes and composition of emitted gases changed. This extended history complicates attribution of the elevated porosity to any specific time or emissions source. Porosity would have formed naturally over the weathering history of the rock. However, elevated porosity within the weathered rind is observed proximal to Dampier, within a region spatially coincident with current elevated concentrations of NO². This association suggests a link between emissions and the elevated porosity. Both NOx, which include NO², and SOx which include SO², are considered reactive gases, which means that they react in the atmosphere to form nitric and sulfuric acids, which can increase the rate of rock weathering.” (Evans 2026)

“Damage to landscapes such as Murujuga rarely have a single cause. We’re tracking how many factors interact, sometimes over decades. The fourth and final year of this research will focus on the interplay of air quality, rock surfaces and microbial communities. We will also complete the environmental criteria to protect Murujuga in the long term, with a focus on ammonia and ozone, in addition to sulphur dioxide and nitrogen dioxide. However, ongoing monitoring will continue to ensure the protection of the rock art.” (Stevens 2026) This damage has accumulated over time, and perhaps will hopefully be prevented in the future. This is, however, not the only site by any means where rock art has been damaged by industrial pollution. Indeed, using the findings of both the 2017 study (Black et al.) and the 2026 study (Evans et al.) these processes are constantly at work at many rock art sites, if not all.

One site that I know well, here in Colorado, is not far from the Hayden Power Plant in Hayden, Colorado. This is a 465 megawatt coal generating station operated by Xcel Energy Company. This is quite near the Hayden pictograph site which is found along Highway 40. As the photographs show, the rock face here is extremely degraded.

This damage is not just from the shotgun pellets scattered all over the equestrian on the left (seen as faint white spots). The coal plant emissions cannot be doing this rock art panel any good. Wouldn’t it be a lovely surprise to find something happening to rock art that is good for its preservations?

ORGANIZING PATTERNS IN CAVE PAINTING?

Horse, bison and reindeer, Chauvet Cave, France. Internet image, public domain.

From the discovery of the painted caves of Europe (and the eventual acceptance of their authenticity) people have been trying to reason out a meaning for these images. Of course, one of the first theories posited to explain them was hunting magic, the idea that creating the image of a game animal would improve one’s chances of success in the hunt. Another way of looking at this art was to attempt organizational analysis, what would be called ‘design’ in art history.

In ‘The Hunters of Prehistory’, in 1989, Andre Leroi-Gourhan wrote “it is certain that the men of the Upper Paleolithic had a highly developed system of beliefs, expressed in symbolic images related to the world of hunting. It was long believed that the animals represented prey, whose portrait was ‘killed’, and so, by magic, the animal itself. The detailed study of some one hundred ornamented caves in France and Spain revealed that, although the caves don’t follow the rules of modern composition and perspective, the positions of the images could not be explained solely by chance.” (Leroi-Gourhan 1989:137-138)

When interest turned to the design of the painted panels (their patterning) relationships between various species have been posited and expressed. “The list of animals represented on walls is shorter than for those depicted on bone artifacts. On walls horse-bison plus ibex is the most widely distributed assemblage. Horse and bison (or auroch) make up the basic formula, but examples of just these two species are rare. In ond case, the figures are located face to face on two walls.” (Leroi-Gourhan 1989:140) So here is posited a relationship between animal imagery that leads to design decisions on placement.

Other species are assigned places in these assumed relationships as well. “The most dangerous animals – bear, large felines and rhinoceros – have positions at the edge of the engraved panels (Les Trois-Freres), in the grouping farthest away from the entrance (Lascaux), or simply at the end of the grouping (Labastide).” (Leroi-Gourhan 1989:140) In this he is leaning on a much shakier assumption, indeed, perhaps the bear, large feline and rhinoceros are the important groupings, and the other animals grouped somewhere away from them.

What seems to have been missing in these analyses is any indication of the painting style of individual animals. In some cases the hand of the artist is recognizable in a group of animals, but in other instances animals in close proximity may have been done by different hands at different times. This would make it somewhat harder to state a certain relationship between animals. Different minds and different artists may not see the supposed rules quite the same way. In other words, I might paint the bison here just because I want the bison here, irrespective of other animals in its vicinity.

A new study, and statistical analysis, of painted caves in France, Spain, and Italy has come out with conclusions that re-open the arguments about intentional groupings of painted subjects.

“Taken together, the network-based results support the existence of an underlying organizational grammar governing the combination and distribution of themes in Magdalenian cave art. This structure operates at multiple, interrelated levels: through recurrent thematic associations within panels; through hierarchical differentiation, whereby certain motifs occupy structurally central positions; and through spatial patterning, expressed in the uneven distribution and reiteration of motifs across compositional units. Within this framework, large herbivores—particularly bison, horse, and ibex—emerge as key organizing themes, while other motifs appear to fulfill more contextual or articulatory roles.” (Intxaurbe 2026)

“These findings are consistent with long-standing structural interpretations of Upper Paleolithic parietal art and extend them by demonstrating their statistical robustness within an expanded, systematically documented, and partly unpublished corpus. The minimum spanning tree analysis further refines this picture by identifying bison as the primary structuring node of the thematic hierarchy. This configuration closely matches patterns previously described for both Cantabrian and Pyrenean contexts and gains particular significance in the Basque region, which occupies an intermediate geographical and cultural position between these areas. However, sensitivity analyses indicate that the precise hierarchical ordering may vary depending on the inclusion or exclusion of specific categories or assemblages, with ibex or horse occasionally occupying the most central position. This variability does not undermine the overall structure; rather, it suggests the existence of a stable triadic core—bison, horse, and ibex—whose internal ordering remains flexible. The recurrence of this triadic configuration across analytical variants supports the hypothesis of partially shared organizational principles operating within interconnected Magdalenian symbolic networks, while the shifting prominence of each element points to complementary rather than strictly hierarchical thematic roles.” (Intxaurbe 2026) This analysis has a renewed reference to Leroi-Gourhan’s bison, horse and ibex centrality.

“Beyond these substantive results, this study highlights the methodological importance of grounding statistical analyses of Paleolithic art in empirically controlled and taphonomically assessed datasets. By integrating geoarcheological evaluation, detailed spatial documentation, and an open, reproducible computational workflow, the approach aims to minimize interpretative biases previously identified in the reuse of fragmentary or insufficiently contextualised corpora. At the same time, we deliberately refrain from advancing speculative interpretations concerning symbolic meaning or narrative content. While the analyses demonstrate structured organization and relational regularities, they do not—and cannot—provide direct access to the social meanings or underlying symbolic intentions.” (Intxaurbe 2026) The organizational and relational regularities mentioned may be as much an artifact of the viewer than the creator. ‘I will keep looking until I find what I want to see.’ So Intxaurbe may have covered more aspects of the subject than I am aware of. For instance, has he considered things like ratios of size of images to distances apart? Or, did he look at colors in his relational analysis?

Horses, aurochs and reindeer, Chauvet Cave, France. Internet image, public domain.

With an admirable lack of hubris, Intxaurbe offers his work as a tool or an approach to aid others. He is not claiming to have solved everything.

“Rather than offering definitive interpretations, this work should be understood as a methodological contribution and an invitation to further comparative research. More broadly, the approach offers a formal tool for investigating the internal organization of symbolic systems and is therefore potentially relevant to adjacent fields such as epigraphy, paleography, or historical linguistics, where co-occurrence and combinatorial structure play a central role. The accumulation of comparable, well-documented datasets and the adoption of shared analytical frameworks represent the most promising path toward refining our understanding of Paleolithic graphic systems.” (Intxaurbe 2026) There is, indeed, much truth to this. There are great portions of the paper by Intxaurbe that are based upon mathematics and statistical analysis, and I confess that I cannot understand much of that. An education in traditional art history does not include any of these concepts. I point this out to say that he may cover certain aspects of this subject that my reading of his study did not give me insight to.

I will not argue with these findings because, to a certain extent, I can believe that this may be true for certain cave artists, at certain times and in a certain place. My objection is the old one that having found something that works in interpreting or analyzing an example of rock art it becomes the only explanation considered. I have also frequently referred to my skepticism about analyses proven by statistics, especially when the data has to be massaged to get to the end result sought for – ‘I want to find this so I will keep massaging the data until I do.’ This is, to me, analogous to Laurenty Beria’s answer to Joseph Stalin, “show me the person and I will find the crime.”

As someone who has studied art history for sixty years I am just unable to accept any ‘one answer fits all’ theory. I see no reason not to assume that one artist painted a horse on the cave wall, and fifteen years later another artist wanted to paint a bison and found a convenient spot. In such a case it would be hard for me to agree that they are there in a mutual relationship. Intxaurbe has, however, produced a piece of work that deserves serious consideration. Read his paper, and who knows, you may agree with him.

CHINESE PICTOGRAPH PAINT CONTAINS HUMAN BLOOD:

Zuojiang Hashan pictographs. Internet image, public domain (photograph sharpened with chatGPT).

How well a painted image will last on a cliff or boulder depends upon a number of factors. One factor, of course, is the kind of rock it is painted on, how hard or how soft? Another factor is the weather itself and the sites exposure to it. Is it directly in the Sun’s fading rays, is it in a location that is hit by rain, etc.? Another, and perhaps most important, factor is the composition of the paint itself. Is the pigment durable or fugitive? How thoroughly does the binder in the paint harden and hold on to the rock surface?

Zuojiang Hashan pictographs. Image, science.org.

The images painted in one section of China have long mystified scientists with their clarity and appartent durability. “The Zuojiang Huashan Rock  Art Cultural Landscape was created over the course of nearly 700 years, between the fifth century BCE and the second century CE, by the Luoyue people – a matriarchal, hunter-fisher-gatherer society that lived in southern China. The images are found across 80 sites along a 260-kilometer stretch of river cliffs. Given that the area is battered by regular monsoons, the art is remarkably intact, especially compared with murals made hundreds of years later in other parts of the country.” (Sagar 2026) Normally, frequent monsoon rains would be thought to doom painted images to quick destruction.

These painted images, however, act very different – they are exceedingly durable. “The pigments are so firmly bonded to the bedrock that when peeling occurs, it is the limestone layer itself that detaches along with the pigments,” says Meng Wu, a chemist at Shandong University.  “The material stability of this art has long been an unsolved mystery.” (Sagar 2026)

“These paintings are bound to the rock so well that scientists had to use electric drills to scrape off samples for testing, which revealed that the paint contained lime, red clay, and blood from women who’d just given birth.” (Spitz 2026) The most surprising component of the paint used was blood, which came from both humans and animals. “The human portion contained two proteins that were linked to pregnancy, breastfeeding, and female reproductive biology. Therefore the team concluded that these proteins likely came from women who had very recently given birth, and that the blood came from routine postpartum bleeding.” (Spitz 2026) This is a likelihood, not a certainty, as the proteins in question are not totally unique to women and childbirth. Much of the durability of the red paint is due to the lime and red clay ingredients setting up in a reaction much like cement. Then, adding the proteins from blood, we can expect this to only enhance the durability of the paint.

As the Luoyue creators of this rock art are believed by historians to have been a matriarchal society, the use of postpartum blood in the paint may have had a deeply spiritual significance to the people. Therefore the act of creating the rock art may have also involved significant ritual contexts. At least that makes a great deal of sense.

CARVED IVORY BIRDS FROM HOHLE FELS CAVE:

For many years excavations have been underway at theh caves of the Ach Valley of the Swabian Jura, near Schelkiingen in southwestern Germany. These sites, particularly the caves Hohle Fels and Geissenklosterle, have produced an amazing number of carved ivory, antler and bone figurines along with other artifacts.

“The cave site of Hohle Fels was occupied during the Aurignacian period of prehistory (43,000 to 28,000 years before present), when early humans – thrived in Europe following the disappearance of the Neanderthals. These groups created an explosion of art, some of which had never been seen before in human history, including so-called Venus figurines, musical instruments, elaborate jewelry and cave paintings. Much of this art involved drawing and carving animals that the Aurignacian people would have seen on a day-to-day basis.” (Killgrove 2025)

Sculptures recovered from Hohle Fels include a small bird assumed to represent a water bird, animal figurines, a therianthrope known as the Lion Man, a flute (made from a vulture’s femur) and the famous Hohle Fels Venus. “The Hohle Fels bird is not the oldest figurative sculpture in Europe. That title has been taken by another discovery from the same cave in 2008: the Venus of Hohle Fels, a sculpture of a woman with exaggerated breasts and thighs, which was created 41,000 years ago.” (Killgrove 2025) On 18 July 2026 I published an article on RockArtBlog with the title “CLAVIFORM, VENUS OR STEATOPYGIA?” which questioned the enlarged buttocks seen on Paleolithic Venus figures and in some rock art, suggesting that it might represent the phenomenon of steatopygia.

Does this collection of work represent the beginning of figurative sculpture in Western civilization? Ewen Calloway suggest just that. “The entire collection of ivory carvings at Hohle Fels suggests that something very new was happening around 40,000 years ago in the south German mountains, as the people who created the Aurignacian culture invented types of figurative art and music akin to what we have today.” (Killgrove 2025)

These carvings strike the modern eye as extremely interesting, as if we have not changed that much in the period between their creation in the Aurignacian and now. “There’s something magical about these pieces,’ says Nicholas Conard, an archeologist at the University of Tubingen in Germany, who has led the excavation of Hohle Fels since the late 1990s. Conard argues that the artistic capabilities on display at Hohle Fels and nearby caves mark a shift in cognitive and cultural sophistication that might have helped these humans to flourish in ice-age Europe, when other groups vanished. He now hopes to test this theory by collecting ancient DNA from the Hohle Fels cave sediments.” (Callaway 2026) This would, at least, allow him to determine whether the carvings were made by modern humans, or our predecessors in Eutope.

Now, new discoveries at Hohle Fels have made the news. During the  2025 field season, Alexander Janas, an archeologist at the Senckenberg Center for Human Evolution and Paleoenvironment in Tubinge, Germany, discovered two more miniature bird carvings thought to resemble ptarmigans. “This week, Janas and his colleagues announced their latest treasures: a pair of tiny bird figurines carved from mammoth ivory, and vulture bone flute fragments, discovered during the 2025 field season. The artifacts were unveiled at the Museum of Prehistory and Ice Age Art in Blaubeuren, Germany, on 29 July.” (Callaway 2026) These two new birds are indeed tiny, measuring 2 – 3 cm. each.

And, as I said above, we immediately find these birds charming. They are cute. What else might be waiting to be discovered?
