Taeniodonta

Taeniodonta ("banded teeth") is an extinct order of eutherian mammals, that lived in North America and Europe from the late Cretaceous (Maastrichtian) to the middle Eocene. They were among the first mammals to evolve large body sizes (comparable to a modern wild boar or American black bear), as well as ever-growing teeth for eating tough plants.

Psittacotherium ("parrot beast") is an extinct genus of taeniodonts from extinct tribe Psittacotheriini within subfamily Stylinodontinae and family Stylinodontidae, that lived in North America from early to late Paleocene. With a weight between and , and length of , it had similar size of a large dog.

Stylinodon ("tooth with pilar-like fibers") is an extinct genus of taeniodonts that lived in North America from early to middle Eocene.

Stylinodontidae ("teeth with pilar-like fibers") is an extinct family of mammals from extinct superfamily Stylinodontoidea within extinct order Taeniodonta, that lived in North America from the early Paleocene to middle Eocene.

Ectoganus ("outside brightness") is an extinct genus of taeniodonts from tribe Ectoganini within subfamily Stylinodontinae and family Stylinodontidae, that lived in North America from the Late Paleocene to Early Eocene.

Schowalteria is a genus of extinct mammal from the Cretaceous of Canada. It is the earliest known representative of order Taeniodonta, a specialised lineage of eutherian mammals otherwise found in Paleocene and Eocene deposits. It is notable for its large size, being among the largest of Mesozoic mammals, as well as its speciation towards herbivory, which in some respects exceeds that of its later relatives.

Wortmania ("Wotman's animal") is an extinct genus of taeniodonts from extinct subfamily Wortmaniinae within extinct family Stylinodontidae, that lived in North America during the early Paleocene.

Conoryctes ("cone digger") is an extinct genus of taeniodonts from extinct tribe Conoryctini within extinct subfamily Conoryctinae and extinct family Conoryctidae, that lived in North America from early to middle Paleocene.

Conoryctella ("cone digger of earth") is an extinct genus of taeniodonts from extinct tribe Conoryctellini within extinct subfamily Conoryctinae and extinct family Conoryctidae, that lived in North America during the early Paleocene.

Conoryctidae ("cone diggers") is an extinct family of mammals from extinct order Taeniodonta, that lived in North America and Europe from the early Paleocene to early Eocene.
