A newly discovered adult hominid mandible (BK 8518) from Baringo, Kenya, is described and assessed. The corpus, many of the tooth crowns, and most of the left ascending ramus are preserved. The teeth are heavily and asymmetrically worn. Compared with BK 67 (the 1966 mandible) the body of BK 8518 is more robust; the internal symphyseal buttressing is more pronounced; the M3s have seven cusps and exceed the M2s in size. There are no compelling reasons, however, to attribute the two mandibles to different taxa and, in view of the lack of any comprehensive taxonomic diagnosis for Homo erectus, "erectus-like," and habiline mandibular remains, the new specimen is also best regarded as Homo sp. indet. (aff. erectus).
Discoveries of organic remains are rare on Late Stone Age sites in southern Africa. However, it is known from numerous historical records that in the case of the Wilton people the perishable elements of the material culture were in many cases the most important aspects of the tool-kit of Late Stone Age man.The prehistoric settlements at Gwisho hot-springs, Lochinvar, Zambia, assume particular importance, for excellent circumstances of preservation have enabled us to make an exceptionally complete reconstruction of Late Stone Age economy and material culture in a savannah woodland and riverside environment. The object of this paper, in advance of a comprehensive study, is to describe some of the wooden implements found at the sites during recent excavations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
