The Pleistocene high-elevation environments between 2.02 and 0.6 Ma at Melka Kunture (Upper Awash Valley, Ethiopia) based upon stable isotope analysis
Autor: Giuseppe Briatico, Hervé Bocherens, Denis Geraads, Rita T. Melis, Margherita Mussi
Publikováno v: Scientific Reports, Vol 14, Iss 1, Pp 1-11 (2024)
Abstract Pleistocene environments are among the most studied issues in paleoecology and human evolution research in eastern Africa. Many data have been recorded from archaeological sites located at low and medium elevations (≤ 1500 m), whereas few

A new late Miocene elasmotheriine rhinoceros from Morocco
Autor: DENIS GERAADS, SAMIR ZOUHRI
Publikováno v: Acta Palaeontologica Polonica, Vol 66, Iss 4, Pp 753-765 (2021)
We describe here the first definite representative of the subfamily Elasmotheriinae in North Africa. It comes from the upper Miocene site of Skoura near Ouarzazate, on the southern slope of the Central High Atlas in Morocco. It consists of a virtuall

First high resolution chronostratigraphy for the early North African Acheulean at Casablanca (Morocco)
Autor: Rosalia Gallotti, Giovanni Muttoni, David Lefèvre, Jean-Philippe Degeai, Denis Geraads, Andrea Zerboni, Valérie Andrieu-Ponel, Matteo Maron, Serena Perini, Mohssine El Graoui, Séverine Sanz-Laliberté, Camille Daujeard, Paul Fernandes, Mathieu Rué, Lionel Magoga, Abderrahim Mohib, Jean-Paul Raynal
Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-14 (2021)
Abstract The onset of the Acheulean, marked by the emergence of large cutting tools (LCTs), is considered a major technological advance in the Early Stone Age and a key turning point in human evolution. The Acheulean originated in East Africa at ~ 1.

The fossil record of camelids demonstrates a late divergence between Bactrian camel and dromedary
Autor: Denis Geraads, Gilles Didier, Andrew Barr, Denne Reed, Michel Laurin
Publikováno v: Acta Palaeontologica Polonica, Vol 65, Iss 2, Pp 251-260 (2020)
A new compilation of the Old World fossil record of Camelidae and a recent phylogenetic analysis allow a new assessment of the timing of the clade’s diversification. Using a recent implementation of the fossilized birth-death process, we show that

Fossils from Mille-Logya, Afar, Ethiopia, elucidate the link between Pliocene environmental changes and Homo origins
Autor: Zeresenay Alemseged, Jonathan G. Wynn, Denis Geraads, Denne Reed, W. Andrew Barr, René Bobe, Shannon P. McPherron, Alan Deino, Mulugeta Alene, Mark J. Sier, Diana Roman, Joseph Mohan
Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-12 (2020)
Key events in human evolution are thought to have occurred between 3 and 2.5 Ma, but the fossil record of this period is sparse. Here, Alemseged et al. report a new fossil site from this period, Mille-Logya, Ethiopia, and characterize the geology, ba

International audience; While the emergence of the Acheulean is well documented in East Africa at ~1.7 Ma, subsequent developments are less well understood and to some extent controversial. Here, we provide robust evidence regarding the time period b

International audience; Pleistocene archaeology records the changing behaviour and capacities of early hominins. These behavioural changes, for example, to stone tools, are commonly linked to environmental constraints. It has been argued that, in ear
