The “Sima del Elefante ” cave site at Atapuerca (Spain)

The “Sima del Elefante ” (TE site) (Atapuerca, Spain) is a major cave infill with a stratigraphic succes-sion 25 m thick and 15 m wide, wealthy in animal bones and evidences of human occupation at different Pleistocene ages. TE site is under systematic excavation since 1996, and the inferior and superior levels are being dug up independently. The exposed section has been divided into 21 lito-stratigraphic units defined by major unconformities. Concerning the cave history, at least three main infill phases have been identified. The lower phase (TE8-TE14) is dated to Early Pleistocene (between 1.1 and 1.4 million years ago) on the basis of inverse paleomagnetics and belonging to the later Early Pleistocene on the basis of biochronology. The TE lower phase is providing a rich faunal assemblage, and shows evidence of human occupation. A set of stone tools of flint, and possibly, calcareous, is being found at these lev-els. Hence, the lower part of the TE section documents early presence of hominids in Europe and consti-tuted an important element in the understanding of human dispersions out-of-Africa. The middle phase (TE15-TE19) dated to Middle Pleistocene and it is further sud-divided into a basal part (TE15-TE17), still largely unexplored, but no vertebrate fossil record is present at this levels. Units TE18, and mainly TE19 unit, date to late Middle Pleistocene, and contain an abundant record of large mammals as well as ston
