FerugliotheriumFerugliotherium is a genus of mammals from the extinct suborder Gondwanatheria, that lived in Patagonia, specificially Los Alamitos, Argentina. It is the only genus in the family Ferugliotheriidae. These mammals lived during the Upper Cretaceous period, which is part of the "Age of Dinosaurs". Classification The genus and species were named by the Argentinian paleontologist Jos Bonaparte in 1986 (Bonaparte, 1986). Bonaparte also named the Vucetichia gracilis genus and species in 1990 (Bonaparte, 1990), which was synonymized with Ferugliotherium by David Krause in 1993 (Krause, 1993). Gondwanatheria is no longer regarded as part of Multituberculata but, according to Kielan-Jaworowska & Hurum, 2001, p.411: - "a few specimens described as ?Ferugliotherium," are from Multituberculata. "These poorly known specimens (not discussed herein) demonstrate that a branch of multituberculates apparently lived during the Late Cretaceous in South America."
As Gondwanatherians aren't Multituberculata, these remains would clearly not belong to this genus or grouping. The position of Gondwanatherians within Mammalia is not yet clear. References - Jos F.
