Alphadon is a small prehistoric marsupial that appeared in film Walking with Dinosaurs: The Movie. It is seen being chased by an inquisitive baby Pachyrhinosaurus.


As a metathere mammal, it was related to Didelphodon and the modern marsupials; it was small in size and probably similar to the modern opossum of North America. Its name means "First tooth." Alphadon lived from 76 to 63 million years ago.
