Triisodontidae is an extinct paraphyletic family of hoofed mammals. All undisputed triisodontid genera lived during the Paleocene in North America.[1][2] Triisodontids were the first large predatory mammals to appear in North America following the extinction of the non-avian dinosaurs.[3][4] They differ from mesonychians in having less highly modified dentition.[5]
Because of their similar tooth morphology, triisodontids were considered to have been mesonychians by many experts.[5][1][6] However, a recent study recovered them outside the order and instead a paraphyletic group of stem-mesonychians.[7] Other studies have found them to be more closely related to modern ungulates than to mesonychians.[8][9] Phylogenetic analysis suggests mesonychians splitting off from triisodontids during the Late Cretaceous.[10]
