Pantodonta

Pantodonta is an extinct order (or, according to some, an suborder) of eutherian mammals. These herbivorous mammals were one of the first groups of large mammals to evolve (around 66 million years ago) after the end of the Cretaceous. The last pantodonts died out at the end of the Eocene (around 34 million years ago).

Barylambda (Greek: "heavy" (baros), "lambda" (lambda) in a reference to larger size than that of Pantolambda) is an extinct genus of pantodont mammal from the middle to late Paleocene, well known from several finds in the Wasatchian (NALMA classification) DeBeque Formation of Colorado and the Clarkforkian Wasatch Formation to Tiffanian Fort Union Formation in Wyoming. Three species of Barylambda are currently recognized. The creature likely lived a life similar to that of a modern tapir, browsing on foliage and soft vegetation. Barylambda seems to have been quite successful for an early pantod

Coryphodon (from Greek , "point", and , "tooth", meaning peaked tooth, referring to "the development of the angles of the ridges into points [on the molars].") is an extinct genus of pantodonts of the family Coryphodontidae.

Pantolambda (Greek: "all" (pantos), "lambda" (lambda), in a reference to the shape of upper premolars, similar to the Greek letter lambda) is an extinct genus of Paleocene pantodont mammal. Pantolambda lived during the middle Paleocene, and has been found both in Asia and North America.

Titanoides is an extinct genus of pantodont mammal that lived in North Dakota and as far north as central Alberta. They were up to long and up to in weight, being the largest mammals of their habitat, a tropical swampland where the main predators were crocodiles. They had a bear-like appearance with huge canines, short limbs and five clawed digits; however, they were herbivores and probably had traits and attributes more similar to diprotodontids.

Coryphodontidae is an extinct family of pantodont mammals known from the Late Paleocene to the Middle Eocene of Eurasia and North America.

Described from a skull, Hypercoryphodon is a quadrupedal hippopotamus-like herbivore that may have been able to adapt its feeding to suit different situations. It is thought to have possibly lived in wetland to forest ecosystems that it might have shared with other herbivores such as dinoceratans like Gobiatherium. The low-crowned teeth of Hypercoryphodon were adapted for feeding on soft aquatic vegetation.

Barylambdidae is an extinct family of pantodont mammals from North America.

Alcidedorbignya is an extinct pantodont mammal known from the Early Paleocene (Tiupampan SALMA, ) Santa Lucia Formation (, paleocoordinates ) at Tiupampa near Mizque, Cochabamba, Bolivia.

Bemalambda (meaning "stepped lambda") is a genus of extinct mammal, belonging to the pantodonts. It lived in the lower-middle Paleocene (about 63–58 million years ago) and the fossil remains have been found in China.

Pantolambdidae is an extinct family of pantodont mammal in the order Pantodonta.

Bemalambdidae is an extinct family of pantodont mammals known from Early and Middle Paleocene of China.

Haplolambda is an extinct genus of pantodont mammals in the family Barylambdidae from the Paleocene of North America, containing two species: H. quinni known from Colorado and H. simpsoni from Utah.
