Neanderthal kneeprint – Misryoum reports on evidence that Neanderthals knelt near Bruniquel cave’s stalagmite rings, with DNA possibilities.
A possible Neanderthal kneeprint could be hiding beside one of prehistory’s strangest monuments: circular structures built from broken stalagmites deep inside Bruniquel cave.
In a limestone cave system in what is now southwestern France. Misryoum says researchers have focused on a clay impression that may reflect the moment a kneeling person pressed weight into the ground.. The idea emerged because later activity by bears erased most other traces. leaving the clay imprint as one of the few surviving marks from the time when the stalagmite circles were being constructed.
This matters because “kneeprints” would add a new kind of evidence to a field that has long relied on footprints. If the impression truly comes from a kneeling Neanderthal, it could help reconstruct not just what happened at Bruniquel, but how people moved and positioned themselves in the dark.
Misryoum notes that the stalagmite circles themselves were discovered in the 1990s and later described in research published in the mid-2010s.. While ancient footprints are widely studied. the question of whether kneeprints can be identified and compared has received far less attention. prompting researchers to plan controlled experiments.. The approach is straightforward in concept: record how knees imprint different clays. so that future comparisons are grounded in real. measurable patterns.
A key part of the investigation is preservation.. Misryoum reports that the impression is ancient and appears to have been sealed under a thin coating of calcium carbonate. the same mineral material that formed the cave’s stalagmites.. That covering can act like a natural protective layer. and Misryoum says a specialist assessment also indicates the mark does not match what would be expected from a bear print.
Meanwhile, there is also the tantalizing possibility of biomolecular evidence.. Misryoum says researchers are exploring whether Neanderthal DNA could survive within calcite. since DNA can diffuse into mineral material and persist under certain conditions.. If the kneeprint was mineralized quickly enough, tiny biological traces may have been locked in rather than fully breaking down.
This matters because genetic traces could shift the evidence from interpretation toward confirmation. In sites where animal activity has blurred the record, even small, well-preserved samples can be decisive.
Misryoum adds that the people responsible for the stalagmite structures are strongly linked to Neanderthals.. At the time the cave features were formed. Homo sapiens was not present in Europe. and researchers point to additional cave chronology work showing that the entrance later collapsed and stayed sealed for a long period.. That helps reduce the risk of mixing events from different groups and times.
Beyond identifying the kneeling mark. Misryoum reports that the research team is developing ways to “fingerprint” the broken stalagmites by analyzing their mineral composition.. The goal is to trace where the broken pieces came from inside the cave. and potentially whether materials were brought from farther away or even from other caves.. Pinpointing the sources could reshape ideas about why the circles were built. whether for cultural or symbolic purposes or for something more practical—despite the fact that the chambers where the structures sit lie more than 300 meters from the entrance. where lighting and daily life become complicated questions.
At Misryoum, the bigger takeaway is the way this project keeps opening new doors even after years of study. Each additional observation in Bruniquel cave, from clay impressions to mineral layers, offers another chance to read a human story written in stone.
