   Abstract:
   The fossil mammals of the lower Eocene part of the Willwood Formation in the southern Bighorn Basin constitute by far the largest sample of stratigraphically documented fossil mammals of any age from anywhere in the world. For this reason, the southern Bighorn Basin Willwood sample of fossil vertebrates has become the most important for empirically derived paleontological studies of tempo and mode of evolution in Mammalia. Locality data for 1472 Willwood fossil mammal sites and the detailed stratigraphic correlation of 941 of them into measured stratigraphic sections afford a framework for the biostratigraphic integration of nearly 80 000 catalogued and at least 30 000 uncatalogued specimens. A preliminary list of the Willwood mammal fauna of the south-central and southeast Bighorn Basin and mammalian compositions for some of the most important sites are presented. Locality and stratigraphic correlations are also provided for 37 fossil plant localities. -from Authors
