Abundant lithic industry was discovered in this rock shelter -tools made by prehistoric man- belonging to two species of human ancestors, Neanderthals and Cro-Magnons, as well as other archaeological remains, such as animal bones (rhinoceros, mammoth, bison, chamois, goat, etc.).
Some of the oldest art forms of humanity are also found on its walls: a set of non-figurative engravings belonging to the Aurignacian culture (more or less 30,000 years before the present).
El Conde Cave certainly contains in its strata the greatest mystery in recent prehistoric research, namely the coexistence of the last two human species who fought to adapt to the rigours of the European glacial climate: Neanderthals and Cro-Magnons.
