The larger mammal palimpsest from TK (Thiongo Korongo), Bed II, Olduvai Gorge, Tanzania

Ever since Mary Leakey's initial excavations in the 1960s, TK (Thiongo Korongo) has been recognized as one of Olduvai Gorge's most important Acheulean sites. The significant concentrations of lithics and fauna reported by Mary Leakey have been augmented in recent years by Santonja et al., who argue that human activities appear to be largely related to the manufacture of lithic implements. In contrast, the faunal remains have been interpreted to be of uncertain origin, and their anthropogenic nature remains in question. This paper presents new data on the formation of the TK bone accumulation. Our results reveal a diverse list of taxa, many of which reflect open habitats. Only limited evidence of anthropogenic activity is documented.
