We also known that H. heidelbergensis sometimes visited Galería. When it contained a dead animal, they entered and got it ready to take it away for consumption elsewhere. Limbs and heads were taken, which is why we have mainly found parts of the trunk (vertebrae, ribs, etc.). The groups that climbed down into Gallery brought stone tools that had been manufactured outside. Only the tools themselves have been discovered inside, but none of the flakes from the production process or the natural blocks they were hewn from.

Part of a skull was discovered in 1995, and back in 1976, a jawbone fragment was unearthed, both from the human species Homo heidelbergensis. These are the only two human remains detected so far.

The animals found in this cave include horses, red deer, bison, rhinoceros and carnivores including bears, lions, dholes, foxes and wildcats. We know that bears lived here because signs of their scraped nails can still be seen on the clay walls, hence the name of the site, Covacha de los Zarpazos (Claw Mark Cavity).
