The History of Spains Gran Dolina

Gran Dolina is a cave site in the Sierra de Atapuerca region of central Spain, approximately 15 kilometers from the town of Burgos. It is one of six important paleolithic sites located in the Atapuerca cave system; Gran Dolina represents the longest occupied, with occupations dated from the Lower and Middle Paleolithic periods of human history. Gran Dolina has 18-19 meters of archaeological deposits, including 19 levels of which eleven include human occupations. Most of the human deposits, which date between 300,000 and 780,000 years ago, are rich in animal bone and stone tools. The Aurora Stratum at Gran Dolina The oldest layer at Gran Dolina is called the Aurora stratum (or TD6). Recovered from TD6 were stone core-choppers, chipping debris, animal bone and hominin remains. TD6 was dated using electron spin resonance to approximately 780,000 years ago or a little earlier. Gran Dolina is one of the oldest human sites in Europe as only Dmanisi in Georgia is older. The Aurora stratum contained the remains of six individuals, of a hominid ancestor called Homo antecessor, or perhaps H. erectus: there is some debate of the specific hominid at Gran Dolina, in part because of some Neanderthal-like characteristics of the hominid skeletons (see Bermà ºdez Bermudez de Castro 2012 for a discussion). Elements of all six exhibited cut marks and other evidence of butchering, including dismembering, defleshing, and skinning of the hominids and thus Gran Dolina is the oldest evidence of human cannibalism found to date. Bone Tools From Gran Dolina Stratum TD-10 at Gran Dolina is described in the archaeological literature as transitional between Acheulean and Mousterian, within Marine Isotope Stage 9, or approximately 330,000 to 350,000 years ago. Within this level were recovered more than 20,000 stone artifacts, mostly of chert, quartzite, quartz, and sandstone, and denticulates and side-scrapers are the primary tools. Bone have been identified within TD-10, a handful of which are believed to represent tools, including a bone hammer. The hammer, similar to ones found in several other Middle Paleolithic sites, appears to have been used for soft-hammer percussion, that is, as a tool for making stone tools. See the description of the evidence in Rosell et al. listed below. Archaeology at Gran Dolina The complex of caves in Atapuerca was discovered when a railway trench was excavated through them in the mid-19th century; professional archaeological excavations were conducted in the 1960s and the Atapuerca Project began in 1978 and continues to this day.
