Polydolopimorphia is an extinct order of metatherians, more closely related to extant marsupials than other extinct mammals. Known from the Paleocene-Pliocene of South America and the Eocene of Antarctica, they were a diverse group during the Paleogene, filling many niches, before declining and becoming extinct at the end of the Neogene.^[1] It is divided into two suborders, Bonapartheriiformes, and Polydolopiformes ^[2] The morphology of the teeth suggests that polydolopimorphians may be crown group marsupials, nested within Australidelphia. The group contained omnivorous, frugivorous and herbivorous forms.^[3]
