...), was the sister group of Tillodontia, and that both evolved from Cimolestidae ( Didelphodus ), but neither hypothesis has been corroborated by further analysis. No other likely postulate of the affinities of tillodonts has been proposed, and they remain one of the most enigmatic Paleogene clades. In fact, despite...

Tinerhodon especially supports a derivation from cimolestid-like eutherians, as illustrated for instance by its referral to the Cimolestidae by McKenna & Bell (1997) . The cimolestid origin of the Creodonta was initially suggested by Van Valen (1966...

Subsequently, this interpretation of the phylogenetic relationships of taeniodonts was reflected in the classification presented by McKenna and Bell (1997) , who included Procerberus and Cimolestes Marsh, 1889 , in the Family Cimolestidae.
