Amphitherium

amphitherium
Amphitherium is an extinct genus of stem cladotherian mammal that lived during the Middle Jurassic[1] It was one of the first Mesozoic mammals ever described A recently phylogenetic study found it to be the sister taxon of Palaeoxonodon[2]

Etymology

Amphitherium comes from the Greek amphi meaning 'on both sides', and therion meaning 'wild beast' This was in reference to de Blainville's incorrect belief that the original fossil jaw of this animal was not a mammal, but something in between mammals and reptiles
