It has an age of 61 to 65.7 million years, corresponding to the early and middle Paleocene.In outcrops in southern areas of the formation, the Puercan fauna is found in the Arroyo Chijuillita Member, the Torrejonian fauna is found in the Ojo Encino Member, and the uppermost Escavada Member lacks age-diagnostic fossils.In northern outcrops, the two lower formations are indistinguishable, and are called the main body.
Above them are two more informal members. These preserve a younger, Tiffanian fauna. The Puercan and Torrejonian faunas are further subdivided into several biostratigraphic zones. Mammalian groups represented include multituberculates, didelphid marsupials, insectivorans, plesiadapiforms, carnivorans, taeniodonts, mesonychids, condylarths, and cimolestans.
