    "subtitle": null,
    "abstract": "Three species of the cimolestid \nProcerberus \nare currently recognized in the northern North American Western Interior in latest Cretaceous and earliest Paleocene (Puercan North American Land Mammal Age) faunas: \nP. formicarum\n,\n P. andesiticus\n, and\n P. grandis\n. Analysis of a new topotypic sample of \nP. formicarum\n from the Bug Creek Anthills locality provides an estimate of the range of variation of its postcanine dentition. The three currently recognized species occur in Puercan 1 (Pu1) interval zone faunas, but two other occurrences indicate that the genus originated and initially diversified prior to the Cretaceous/Paleogene boundary. Rare occurrences at several localities and entries in faunal lists suggest even greater taxonomic diversity. Limited evidence suggests continued diversification in the later Puercan and possible survival of the genus into the Torrejonian. \nProcerberus grandis\n or a closely related species may be a sister group of primitive taeniodonts.",
