Haramiyavia

Haramiyavia is a genus of synapsid in the clade Haramiyida that existed about 200 million years ago in the Rhaetian stage of the Triassic.[1] Like other haramiyidans, it was likely a non-mammalian mammaliaform.[2][3] It contains a single species, H. clemmenseni from the Fleming Fjord Formation of Greenland,[1] and has been assigned to the monogeneric family Haramiyaviidae.[4]
