Quantifying Oldowan Stone Tool Production at Olduvai Gorge, Tanzania. by Jay S Reti

“…To establish these expectations this research 1) models the expected range of variation through large scale reduction experiments, 2) develops an algorithm to categorize archaeological flakes based on how they are produced, and 3) statistically assesses the methods of production behavior used by Oldowan producing hominins at the site of DK from Olduvai Gorge, Tanzania via the experimental model. Results indicate that a subset of quartzite flakes deviate from the null expectations in a manner that demonstrates efficiency in flake manufacture, while some basalt flakes deviate from null expectations in a manner that demonstrates inefficiency in flake manufacture. …”

Earliest porotic hyperostosis on a 1.5-million-year-old hominin, olduvai gorge, Tanzania. by Manuel Domínguez-Rodrigo, Travis Rayne Pickering, Fernando Diez-Martín, Audax Mabulla, Charles Musiba, Gonzalo Trancho, Enrique Baquedano, Henry T Bunn, Doris Barboni, Manuel Santonja, David Uribelarrea, Gail M Ashley, María del Sol Martínez-Ávila, Rebeca Barba, Agness Gidna, José Yravedra, Carmen Arriaza

“…Stone tool butchery marks on ungulate fossils in several African archaeological assemblages demonstrate a significant level of carnivory by Pleistocene hominins, but the discovery at Olduvai Gorge of a child's pathological cranial fragments indicates that some hominins probably experienced scarcity of animal foods during various stages of their life histories. …”

Lions as Bone Accumulators? Paleontological and Ecological Implications of a Modern Bone Assemblage from Olduvai Gorge. by Mari Carmen Arriaza, Manuel Domínguez-Rodrigo, José Yravedra, Enrique Baquedano

“…A carnivore-made bone assemblage located in the short-grassland ecological unit of the Serengeti (within Olduvai Gorge) was studied. Taphonomic analyses of this assemblage including skeletal part representation, bone density, breakage patterns and anatomical distribution of tooth marks, along with an ecological approach to the prey selection made by large carnivores of the Serengeti, were carried out. …”

PHYLOGENETIC SIGNATURES IN THE JUVENILE SKULL AND DENTITION OF OLDUVAI <em>EURYGNATHOHIPPUS CORNELIANUS</em> (MAMMALIA: EQUIDAE) by RAYMOND L. BERNOR, TIPHAINE COILLOT, DOMINIK WOLF

“…We describe and compare a Eurgnathohippus juvenile skull, RMNH67/5665 from site BKII, Olduvai Gorge, ca. 1.2 Ma. Study of the facial morphology and cheek tooth metrical data including length versus width and protocone length versus width of the dP2, 3 and 4 support the conclusion that this juvenile skull is the species Eurygnathohippus cornelianus, and that in turn Eu. cornelianus is a member of the “Sivalhippus” Complex, which includes the following superspecific clades: Sivalhippus, Eurygnathohippus, Plesiohipparion and Proboscidipparion. …”
