If you like the evolution of mammals, probably you known about the groups of placental mammals found by molecular research: Laurasiatheria, Euarchontoglires and Afrotheria. The last one are the mammals that began their evolutive history in Africa and in the Paleocene occur for first time in diverse sites of the north of the continent, and includes the ancestors of elephants, manatees, hyraxes, aardvarks, tenrecs and extinct groups like embrithopodans and desmostylians. Unfortunately, like is usual in paleontology, the remains of this animals are scarce, generally teeth and fragments of jaws, which complicates the understanding of the history and appearance of the early representatives of these animals.
But we have now a (more or less) complete skull of one of this animals - Ocepeia
. And the description paper (again, courtesy of Plos ONE: www.plosone.org/article/info%3…
) have a 3D model of the skull and an interesting conclusion: Afrotheria could be not a natural group.
