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,[1][2] as well as its speciation towards herbivory, which in some respects exceeds that of its later relatives.[3]

Description

Currently, Schowalteria is considered to be a

Repenomamus giganticus,[2] while posterior analysis showcase it to be as large as latter taeniodonts.[4]

Range

Schowalteria occurs in the

multituberculates
.

Classification

Schowalteria is a taeniodont eutherian. It was initially recovered as a fairly derived member related to

stylinodonts,[1] but more recent examinations show it to be a more basal species within the group, less related to them than Onychodectes.[3]

Biology

In spite of being a basal taeniodont, Schowalteria is fairly derived, perhaps more so than later taenidonts. It shares with them similar speciations towards herbivory and possibly fossoriality,

mastication, making it even more specialised towards processing vegetation.[3]

As one of the largest mammals of its time period and a rather specialised herbivore, Schowalteria was a rather spectacular species among the dinosaur-rich faunas of the end of the Cretaceous.
