Tribosphenida
Infralegion of mammals / From Wikipedia, the free encyclopedia
Tribosphenida is a group (infralegion) of mammals that includes the ancestor of Hypomylos, Aegialodontia and Theria (the last common ancestor of marsupials and placentals plus all of its descendants). It belongs to the group Zatheria.[1] The current definition of Tribosphenida is more or less synonymous with Boreosphenida.[2][3]
