Deltatheridium (meaning triangle beast or delta beast) is an extinct species of metatherian. It lived in what is now Mongolia during the Upper Cretaceous, circa 80 million years ago.[1] It was a basal metatherian, which places it near start of the lineage that led to the marsupials, such as kangaroos, wallabies, koalas, and opossums.
It had a length of 15 cm (5.9 in). Its teeth indicate it was carnivorous.
