What is "pantodonta"

Pantodonta is an extinct suborder (or, according to some, an order) of eutherian mammals. These herbivorous mammals were one of the first groups of large mammals to evolve after the end of the Cretaceous.

Pantodonta include some of the largest mammals of their time, but were a diversified group, with some primitive members weighing less than and the largest more than .

The earliest and most primitive pantodonts, Bemalambda (with a skull probably the size of a dog) and Hypsilolambda, appear in the early Paleocene Shanghuan Formation in China. All more derived families are collectively classified as Eupantodonta. The pantodonts appear in North America in the middle Paleocene, where Coryphodon survived into the middle Eocene. Pantodont teeth have been found in South America ( Alcidedorbignya) and Antarctica, and footprints in a coal mine on Svalbard.
