چکیده
Located within the Beni Fouda intramontane basin, Oued Boucherit area (Guelta Zerga, North East Algeria) hosts a unique succession of archaeological and palaeontological deposits spanning from late Pliocene to Early Pleistocene. While recent work by Sahnouni et al., (2018) mostly focused on two Oldowan levels AB-Lw AB-Up, we present here an updated overview entire sequence, resulting long-term multidisciplinary investigation that started in 1992. In particular, report for first time description oldest dated >3 Ma, uppermost level hosting Acheulean artefacts. The age-depth model initially proposed al. was further extended chronologically constrain whole which spans ∼3.93 Ma at bottom ∼1.65 top. sedimentary sequence records earliest evolutionary steps lithic technology, with early assemblages Ain about 2.44 (AB-Lw) 1.92 (AB-Up) followed ∼1.77-1.72 Hanech El Kherba showing more derived features, appearance ∼1.67 Ma. This chonostratigraphic framework indicates (<1 km2) identified so far Africa. It is also especially striking their chronology somewhat close evidence found Africa South Moreover, least six fossiliferous ranging ∼3.78 1.77-1.72 have been stratigraphically positioned sequence.

Bovids as indicators of Plio-Pleistocene paleoenvironments in east Africa.
Reconstructions of the paleoenvironments of early hominids offer a framework for understanding hominid ecological and behavioral adaptations. Habitat reconstructions typically rely upon various biological or physical habitat indicators, and here we present reconstructions of the Plio-Pleistocene paleohabitats of Koobi Fora and Olduvai Gorge as based on fossil bovids (Artiodactyla: Bovidae). Bov...

15 صفحه اولEvolutionism and North America's archaeological record
The archaeological record of North America has long been a laboratory for evolutionary studies. Beginning in the late nineteenth century, culture historians would regularly turn to evolutionism as a source of archaeological explanations. Sometimes the explanations were broadly Darwinian in nature, with reference to processes such as selection and genetic transmission, and other times they were ...

The Miocene hominoid and Plio-Pleistocene hominid vertebral record is poor. In 1994, a complete atlas of a hominoid was found in breccia at Berg Aukas in Namibia. Its age was estimated to be middle Miocene (13 myr) on the basis of microfauna. This locality yielded the holotype of Otavipithecus namibiensis and the atlas could belong to the same genus. The specimen exhibits clear hominoid traits ...
