Most of what is known about the ecology Patriomanis americanus has been inferred from its close similarity to modern pangolins. It was probably solitary and occurred in low population densities, just like modern pangolins. Occurring only in the Eocene, this species had already become completely edentulous (toothless), and fed on ants and termites, using its long claws to tear into the mounds of these colonial insects. It was probably scansorial (adapted for climbing trees) (PBDB).
