Range and ecology
Fossils of Coloniatherium come from the La Colonia Formation, which outcrops in north-central Chubut Province. The mammalian fossils come from the Mirasol Chico valley. The formation includes fluvial (river), deep-sea, and near-shore deposits, and the mammalian fauna probably comes from an estuary, tidal flat, or coastal plain.[1] La Colonia Formation also contains dryolestoids, such as Coloniatherium and Reigitherium, as well as the enigmatic possible multituberculates Argentodites and Ferugliotherium.[7] Coloniatherium is the largest and most abundant mammal found in the formation.[1]
Mesungulatids, including Coloniatherium, are a highly derived group of mammals, possibly specialized for an
