Deltatheridium is one of the first species of marsupial mammal. It lived in what is now Mongolia during the Upper Cretaceous. It was a basal metatherian, which places it near start of the linage that lead to the marsupials, such the kangaroo, koala, and opposum.
It had a length of 15 cm. Apart from preying on insects, its diet was also composed of small reptiles and what it could scavenge from left-over carcasses, using its sharp canine teeth.
[edit] In popular culture
Deltatheridium is briefly seen in the first episode of the Discovery Channel TV series Dinosaur planet.
