Eupantotheria

from Wikipedia, the free encyclopedia

A group of Mesozoic mammals is summarized as Eupantotheria (formerly Pantotheria) . This group is characterized by certain features in the structure of the teeth, somewhat the absence of the protoconid (a cusp of the upper molars ). Since today's Theria developed from this group, it is paraphyletic , but the group is still in use as a form taxon . However, many species are only known from sparse tooth or jaw finds, which makes the precise systematic classification difficult. Well-known representatives of the Eupantotheria are the Dryolestida , Vincelestes , Amphitherium and the Peramuridae .
