The only pangolin ever discovered in the New World, fossil occurrences of Patriomanis americanus are very rare, largely due to the animal’s lack of teeth (Gebo and Rasmussen 1985). Only three individuals have ever been found, all from Eocene deposits in central Wyoming (PBDB). Though some modern pangolins have considerable ranges, all are solitary and none occur in high population densities. Without further fossil evidence, it is impossible to infer the total distribution of Patriomanis on the continent, although it was likely closely linked to food availability, as in most species.
