Yunnanodon
Yunnanodon is an extinct genus of tritylodontid mammaliamorphs that lived in China during the Sinemurian stage of the Early Jurassic period. Its specific name brevirostre is Latin for "short-beaked" + rostrum ).
Yunnanodon was discovered in the Lower [Lufeng Series], in Yunnan Province, China. As a tritylodontid, it belongs to one of the few cynodont groups to survive the Triassic–Jurassic [extinction event]. It was small, with adult skulls only reaching in length.
