Percussion marks, tooth marks, and experimental determinations of the timing of hominid and carnivore access to long bones at FLK Zinjanthropus, Olduvai Gorge, Tanzania
Competing hypotheses about the timing and nature of hominid and carnivore contributions to the formation of the Plio-Pleistocene bone assemblage from FLK Zinjanthropus are tested. The hypothesesExpand

Systematic Butchery by Plio/Pleistocene Hominids at Olduvai Gorge, Tanzania [and Comments and Reply]
Human origins research by archaeologists has expanded the evidence of the diet and subsistence activities of ancient hominids. We examine an important component of that evidence, theExpand

An experimental model of the timing of hominid and carnivore influence on archaeological bone assemblages
Abstract Experiments were conducted to assess the timing of carnivore and hominid influence on archaeological bone assemblages. The results of disturbance by mainly spotted hyaenas to simulatedExpand

Ratio of central nervous system to body metabolism in vertebrates: its constancy and functional basis.
We present and document an hypothesis that healthy adults of most vertebrate species use 2-8% of their basal metabolism for the central nervous system (CNS). This relationship is constant across allExpand

Blind tests of inter-analyst correspondence and accuracy in the identification of cut marks, percussion marks and carnivore tooth marks on bone surfaces
Abstract We show through blind tests that marks inflicted on bone surfaces by carnivore teeth, hammerstone percussion, and metal knife cutting and scraping can be distinguished with near perfectExpand

A diagnosis of crocodile feeding traces on larger mammal bone, with fossil examples from the Plio-Pleistocene Olduvai Basin, Tanzania.
Neotaphonomic studies have determined the patterns of bone damage created by larger mammalian carnivores when consuming mammalian carcasses. Typically, mammalian carnivores gnaw and break bones toExpand

Late Pliocene Homo and Hominid Land Use from Western Olduvai Gorge, Tanzania
Excavation in the previously little-explored western portion of Olduvai Gorge indicates that hominid land use of the eastern paleobasin extended at least episodically to the west. Finds included aExpand

Captive hyaena bone choice and destruction, the Schlepp effect and olduvai archaeofaunas
Abstract Skeletal element representation at archaeological and palaeontological sites often differs from natural anatomical proportions. At archaeological sites this pattern could result from hominidExpand

Characteristics of an Early Hominid Scavenging Niche [and Comments and Reply]
The characteristics of scavenging opportunities in the Serengeti National Park and Ngorongoro Crater are here documented and applied to the Plio/Pleistocene East Turkana and Olduvai lake basins. TheExpand
