Trigonostylops is an extinct genus of South American meridiungulatan ungulate, from the Late Paleocene to Late Eocene ( Itaboraian to Tinguirirican in the SALMA classification) of South America ( Argentina and Peru) and Antarctica ( Seymour Island). It is the only member of the family Trigonostylopidae.
A complete skull of the type species, T. wortmani, has been found, and it has been classified as an astrapothere based on its large lower incisors. [1]
