Protungulatum donnae

Protungulatum donnae is the type species for the genus Protungulatum, an extinct early form of eutherian mammal. Though it is by no means the earliest mammal in the fossil record, a 2013 study considers P. donnae to be the oldest undisputed placental mammal fossil, though more recent examinations conclude that it was a more basal eutherian and that no placental predates the Paleocene.
