We synthesize African paleoclimate from 150 to 30 ka (thousand years ago) using 85
diverse datasets at a regional scale, testing for coherence with North Atlantic …

Eastern Africa is an important area to study early populations of Homo sapiens because
subsets of those populations likely dispersed to Eurasia and subsequently throughout the …

From its Icelandic origins in the study of visible tephra horizons, tephrochronology took a

A climate/vegetation model simulates episodic wetter and drier periods at the 21,000-y
precession period in eastern North Africa, the Arabian Peninsula, and the Levant over the …

We define 17 African land mammal ages, or AFLMAs, covering the Cenozoic record of the

Abstract 'Nubian Levallois' lithic technology has been found from South Africa to India, it
occurs sporadically over a period of more than two hundred thousand years, and it appears …

We define tephras and cryptotephras and their components (mainly ash-sized particles of
glass±crystals in distal deposits) and summarize the basis of tephrochronology as a …
