Abstract Gondwanatherians are an enigmatic group of extinct non-therian mammals apparently restricted to some of the western Gondwanan continents (Late Cretaceous-early Palaeocene of South America, and Late Cretaceous of Madagascar and India). They developed rodent-like incisors and the earliest known hypsodont cheek-teeth among mammals. Recently, a small rodent-like dentary fragment was recovered from middle Eocene beds on the Antarctic Peninsula, preserving part of the incisor; both the…

Analysis of the unique combination of characters exhibited by Magallanodon shed doubts on the monophyly of Ferugliotheriidae and suggest that South American taxa may be closely related to each other.

Several features suggest the allocation of this specimen among basal polydolopimorphians (Prepidolopidae or, more probably, Glasbiidae), which could offer new insights on the origins and early diversification of Australidelphian marsupials in southern (and northern?) continents.

The craniodental evidence provided by Vintana supports inclusion in Sudamericidae, the monophyly of Gondwanatheria, and the position of Gondeonatheria as nested within or sister to Multituberculata.

The new taxon, here referred to the new family Woodburnodontidae, constitutes the second microbiotherian known from these Antarctic levels and age and confirms the association of representatives of this order within a common, Andean-Patagonian-Antarctic biogeographic region, already present since the Late Cretaceous.

The new taxon adds evidence regarding the extensive radiation of the Gondwanatheria throughout the Southern Hemisphere, persistence of several lineages well after the Cretaceous/Paleogene boundary, and early evolution of hypsodont types among South American herbivorous mammals.
