Table 1S: Miocene Marsupials and Insectivores in the Northern U.S. Rocky Mountains

Faunal lists and age interpretations provided in Alroy (1999) and Janis et al. (1998) were cross-checked and augmented by field observations, primary literature, and unpublished data collected by ADB. Unpublished specimens used in this compilation are mainly from the Hepburn's Mesa (=Chalk Cliffs) area of Montana and the Railroad Canyon / Lemhi Valley region of the Idaho-Montana border and are housed in the University of California Museum of Paleontology and the Carnegie Museum of Natural History. Abbreviations: Ar - Arikareean; He - Hemingfordian; Ba - Barstovian. Subdivisions of Ar, He, and Ba follow Woodburne and Swisher*. Codes such as M18 in the Locality column are links to a database in the ADB lab. Shaded boxes show time periods in which various taxa are known. Dark shading (and black type in the locality column) indicates a locality within the mountains; light shading (and red type in the Locality column) indicates an area that is not within the mountains proper but within 200 km of the mountain front. All localities are within 200 km of the mountainous part of Wyoming, Montana, and Idaho.
