Filikomys is an extinct genus of mammal from the Campanian of North America. A multituberculate, it demonstrates complex social behaviours were present in these early mammals. [3] The type species is F. primaevus; a second, smaller species, F. minor, has been tentatively assigned to the genus. [4]
Filikomys primaevus is a roughly squirrel sized mammal. Several individuals were found within the same locale. The holotype is a dentary, NMC 1890. [3]
From Greek Filikós "friendly", and mys, mouse, alluding to its social behaviour. Primaevus is Latin for youthful. [3]
Filikomys primaevus is nested among the Ptilodontoidea. [3]
Several individuals were found co-habitating a burrow. This suggests multituberculates had complex social behaviours like modern mammals, [3] which in particular have been compared to the social complexity of placentals. [5]
