Argentoconodon is an extinct genus of theriimorph mammal from the Cañadon Asfalto Formation of Patagonia. Whe originally described, it was known only from a single molariform tooth, which possessed a combination of primitive and derived features. The tooth is currently held in the Museo Paleontológico Egidio Feruglio, where it was given the specimen number MPEF-PV 1877.[1] New material described in 2011, including most of a skull and many mostly complete skeletons, show that Argentoconodon was similar to Ichthyoconodon and Volaticotherium within the family Triconodontidae.[2] Several postcranial similarities to Volaticotherium also suggest that it was a gliding or even flying mammal.
