Excavations at a fossil site called Gran Dolina, in Atapuerca, Spain, during 2008. The horizon receiving primary attention of this excavation is called TD-10, which is all that remains of a Homo heidelbergensis camp. Under the plank, a woman in a red sweatshirt is excavating the TD-6 horizon, where the first documented remains of Homo antecessor were discovered.
