Ferugliotherium is an extinct mammal genus from the Upper Cretaceous of Patagonia. It was a member of the extinct taxon of Gondwanatheria, and lived during 'the age of the dinosaurs'.
The position of gondwanatherians within Mammalia is not yet clear.

Genus: Ferugliotherium Bonaparte JF, 1986
Aka: Vucetichia Bonaparte, 1990
Remarks: Gondwanatheria is now generally regarded as not part of Multituberculata but, according to Kielan-Jaworowska & Hurum, 2001, (p.411): "a few specimens described as ?Ferugliotherium," are from multis. "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 multis, these remains would clearly not belong to this genus or grouping.
