Shuotherium is a fossil mammaliaform known from Middle-Late Jurassic of the Forest Marble Formation of England,[1] and the Shaximiao Formation of Sichuan, China.[2][3]
The original holotype is composed of a partial dentary and seven teeth (two which are incomplete).[2] The holotypes for other species of this genus are solely represented by isolated molars. Shuotherium, along with Pseudotribos has been placed in the family Shuotheriidae as a sister taxon of the Australosphenida (see, Yinotheria),[4] making it a relative of modern monotremes. However, some studies place it and other shuothereres as closer to therian mammals,[5][6] and another outside of Mammalia altogether.[7]
