Selenetherium kolleensis nov. gen. nov. sp. : un nouveau Proboscidea (Mammalia) dans le Pliocène tchadien

The survey of proboscides remains recovered from Kollé quarries (Northern Chad) gives evidence of a new taxa of Elephantidae. The anatomical and cladistic analysis permit to consider this new taxa as the sister group of Stegotetrabelodontinae. This new discovery reinforces, once again, the remarkable biodiversity of this group. The proboscidean's association observed in these layers and the evolutionary state of teeth permit us to date the Kollé fossiliferous sector close to the early Pliocene.
