Amphitherium is an extinct genus of stem cladotherian mammal that lived during the Middle Jurassic of England.[1] It was one of the first Mesozoic mammals ever described. A recent phylogenetic study found it to be the sister taxon of Palaeoxonodon.[2] It is found in the Forest Marble Formation and the Taynton Limestone Formation.
