The quality and quantity of the fossils are superb: most of the species to be found there are known from hundreds of specimens. The fossils in the White River Group (and similar deposits in the American west) preserve the entire late Eocene through the middle Oligocene, roughly Summary: The three informal divisions of the Wasatch group of Hayden ()) basal reddish-yellow sandy clays and conglomerates, 2) light-colored rhyolitic ash beds with intercalated white limestone lenses with freshwater shells and leaves, and 3) reddish-yellow sandy clay and irregular sandstone beds named a) Almy formation, b) Fowkes formation, and c) Knight formation in this report.
ABSTRACT-Several recently discovered fossil specimens add to our knowledge of plesiadapiform primates. Micromomys willwoodensis, new species, is a diminutive mic-rosyopid from the early Eocene (early Wasatchian) Willwood Formation of the Clark's Fork Basin, Wyoming. It is larger and more specialized than late Paleocene M. vossae and M.

The Kishenehn Formation of northwest Montana and southeast British Columbia hosts one of the most prolific and diverse assemblages of fossil nonmarine mollusks in North America. More than 76 taxa, of which 41 are newly described species, of middle Eocene to early Miocene terrestrial and aquatic gastropods have been collected and described. This paper reports on the discoveries made in the. The first Eocene vertebrate assemblage known from the Great Basin, the Elderberry Canyon Local Fauna, occurs in rocks referred to the Sheep Pass Formation near Ely, Nevada. Approximately 40 taxa are now known, including small anuran amphibians, small reptiles, birds, and mammals.

This formation is of particular interest to the study of ancient primates because their remains are plentiful. Local heterogeneity was lower in Paleocene backswamp floras, although distinct groups of species dominated in different local fluvial settings such as backswamps and alluvial ridges.
Heterogeneity of backswamp forests increased by about 65% from the early to late Wasatchian (early Eocene). Galecyon is one of the first appearing hyaenodontid creodonts, as well as one of the most poorly known.
New specimens greatly improve our understanding of the morphology of this early Eocene genus, thereby enhance knowledge of the earliest radiation of Hyaenodontidae, and include the first associated upper dental remains, as well as fragmentary cranial remains.
The new records substantially. Two new genera of Clarkforkian and early Wasatchian mammals add to our knowledge of the diversity of early Eocene faunas of the Bighorn Basin.
