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]
