Pantodonta

Pantodonta is an extinct order of mostly large-bodied herbivorous mammals that lived from the Paleocene to the Eocene, chiefly in North America and Asia.

Mammalia: Mammalia is the vertebrate class containing living mammals and their extinct relatives. Pantodonta is an extinct order within this broader class.
Coryphodon: Coryphodon is a large, semiaquatic pantodont genus known from the Paleocene and Eocene of the Northern Hemisphere. Its abundant fossils make it one of the best-known pantodonts.
Cretaceous–Paleogene extinction event: The Cretaceous–Paleogene extinction event was a global biological crisis about 66 million years ago that eliminated non-avian dinosaurs. Pantodonts diversified among mammals in ecosystems reshaped by this extinction.
Dinocerata: Dinocerata is an extinct order of large herbivorous mammals that included Uintatherium. Dinocerates were another giant herbivore lineage, distinct from pantodonts.
Placentalia: Placentalia is the mammal group whose living members nourish fetuses through a placenta. Pantodonts are generally placed among early placental mammals.
Pantolambda: Pantolambda is an early pantodont genus from Paleocene North America. It represents pantodonts near the order's early diversification.
Mammalian radiation: Mammalian radiation is the diversification of mammal lineages into new forms and ecological roles. Pantodonts were one lineage in the post-extinction expansion of mammals.
Tillodontia: Tillodontia is an extinct order of mammals with specialized, rodent-like incisors and broad cheek teeth. Tillodonts shared some herbivorous traits but belonged to a separate mammal order.
Mammalian dentition: Mammalian dentition is the structure, arrangement, and replacement of teeth in mammals. Pantodont classification relies heavily on tooth form and pattern.
Barylambda: Barylambda is a large pantodont genus from the Paleocene of North America. Its massive skeleton illustrates the order's evolution toward very large body size.
