Abstract

A comprehensive paleontological survey of Grand Teton National Park (GTNP) was completed during the 2002 and 2003 field seasons. A number of formations from within the park have yielded a variety of invertebrate, vertebrate, and plant fossils. The following formations (listed in stratigraphic sequence from oldest to youngest) were surveyed in this study: the Gros Ventre, Gallatin Limestone, Bighorn Dolomite, Darby, Madison Limestone, Amsden, Tensleep Sandstone, Phosphoria, Dinwoody, Chugwater, Gypsum Springs, Sundance, Morrison, Cloverly, Thermopolis, Mowry Shale, Frontier, Cody Shale, Bacon Ridge Sandstone, Sohare, Mesaverde, Meeteetse, Harebell, Pinyon Creek, Hominy Peak, Colter, Teewinot, and Huckleberry Ridge Tuff. Comments on the depostional environments of the various formations are based on field observations and analysis of voucher specimens. This study provides a greater understanding of the extensive paleontological resources present in the park.
