Abstract

Ediacara-type body fossils are reported here for the first time from the West African craton in Algeria. This assemblage comprises medusoids comparable to Medusinites sp. and Nimbia, atrace fossil, and a new genus of body fossil with uncertain affinity. The fossils are in sandstones of the Neoproterozoic cover, separated by a major unconformity from the overlying tillite, considered until now to be late Neoproterozoic. Most Ediacaran fauna radiated after the Varanger ice age, and tillites - associated in Ahaggar with molasse of the Pan-African belt - are overlain by carbonates that were deposited during deglaciation and that locally contain Early Cambrian shelly fossils; therefore, we interpret the glaciogenic diamictite as Early Cambrian in age.
