The first true mammals, which were very small, are supposed to appear in the Late Triassic.

Cretaceous placentals, smaller than those of present-day ones, were poised to take over the terrestrial environments as soon as the dinosaurs vanished.

This group includes the native species of Australia, kangaroos, koalas, and the North American opossum.
