Biology:Filikomys
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.[1] The type species is F. primaevus; a second, smaller species, F. minor, has been tentatively assigned to the genus.[2]
Description
Filikomys primaevus is a roughly squirrel sized mammal. Several individuals were found within the same locale. The holotype is a dentary, NMC 1890.[1]
Etymology
From Greek Filikós "friendly", and mys, mouse, alluding to its social behaviour. Primaevus is Latin for youthful.[1]
Classification
Filikomys primaevus is nested among the Ptilodontoidea.[1]
Social behaviour
Several individuals were found co-habitating a burrow. This suggests multituberculates had complex social behaviours like modern mammals,[1] which in particular have been compared to the social complexity of placentals.[3]
