A large bear that ate mostly plants

Although it belongs to the carnivore family, its diet was mainly vegetarian.

Digital reconstruction supplied by the project and generated with Tripo. It is not an archaeological scan or a metric replica; the model is displayed at approximately life size: standing on its hind legs, as in the model, it measures about 3 m, the height of an upright adult male; on all fours it would be around 1.5–1.7 m at the withers. Representation of a Pleistocene cave bear, not fauna living at Çakmaktepe around 9600 BCE.

History and context

European caves preserve thousands of cave bear bones because these animals used them for hibernation and giving birth. They could reach about 3.5 metres in length, but their size does not tell the whole story.

Amino acids in their collagen reveal a strongly plant-based diet. Their specialisation may have become vulnerable when the cold reduced landscape productivity until their disappearance.

Evidence and interpretation

Amino acid isotopes support a plant diet. Climate and vegetation loss are consistent explanations for their extinction, not the only possible cause.

A diet can change depending on the scale of observation

Toll's analyses, in Catalonia, introduce an important nuance to the plant-diet predominance. Collagen isotopes integrate long periods, while dental microwear reflects meals from the last days or weeks. In those specimens, the dental signals also approach omnivorous diets. It does not invalidate all herbivorous results: it indicates that a single label can hide seasonal and regional variation. It is worth imagining populations that responded to specific resources, not animals obliged to always eat exactly the same thing.
