Our research, "Plio-Pleistocene fossil small mammals of the Afar Region (Ethiopia) and their ecological significance for hominin environments" focuses to reconstruct evolution, biogeography, biostratigraphy and biochronology of the Plio-Pleistocene fossil small mammal assemblages (a new and unstudied fossil collection) to explore hominin environments in Afar Region (Middle Awash and Woranso-Mille sites), Ethiopia. The Middle Awash and Woranso-Mille research areas in the Ethiopia's Afar Depression at the junction of the Red Sea, Gulf of Aden, and continental African rifts provide one of the most complete records of deep human prehistory, with a record of fossils from our earliest ancestors to the first members of our species, Homo sapiens. This makes the Afar Basin an excellent focus region to investigate climate and environmental changes that influenced evolution of our own species.
Owing to their unique geological settings and the intensive nature of the fieldwork efforts thus far carried out, the Middle Awash and Woranso Mille sedimentary successions provided new, in-situ, abundant and diverse small mammal fossil assemblages associated with larger vertebrate taxa including hominins from the multiple stratigraphic levels of the Plio-Pleistocene in Afar Rift, Ethiopia. These unstudied fossil small mammal collections from the Middle Awash (1.6 Ma to 0.100 Ma) and Woranso Mille (5.4 Ma to 3 Ma) localities constitute the main study material of this research. This project will elucidate taxonomy, taphonomy and community structure of these new and chronologically very promising fossil collections of the Middle Awash and Woranso Mille sites to explore the ecological context of associated hominin species around last 6 Ma in East Africa.
