ABSTRACT The Paleocene-Eocene transition in North American land-mammal faunas is
well documented on the south side of Polecat Bench and in surrounding badlands of …

Abstract The Tiffanian North American land-mammal age is an informal biochronologic unit
that spans 4.5 myr of the middle and late Paleocene. It is preceded and succeeded by the …

The boundary between the Paleocene and Eocene epochs of the Paleogene period is
associated with a dramatic episode of global change in climate, geochemical cycles, and …

Patterns of mammalian generic turnover, richness, and faunal composition were
investigated for faunas from 17 biostratigraphic zones in middle Paleocene through early …

The mammal fauna of the Willwood Formation, central Bighorn Basin, Wyoming, is ideal for
paleoecological analysis because it is extensive, well studied, and continuously distributed …

An exceptionally rich paleontological site containing thousands of mammalian fossils and
well-dated with 18 radiocarbon samples provides evidence of late-Holocene ecological …

This study provides an analysis of biotic change in successive mammalian communities
during the last 1.8 million years of the Cretaceous (67.3–65.58 Ma) from the Hell Creek …

In spite of decades of intense research directed toward understanding the climates and
ecology of the Great Basin (western United States) during the past 10,000 years, the …

The Paleocene-Eocene boundary is defined chemostratigraphically by the onset of a 100
kyr global carbon isotope excursion (CIE) that is recognized in marine and continental strata …

The McCullough Peaks section of the Willwood Formation in the northern Bighorn Basin,
Wyoming, has produced a rich fossil record of early Eocene mammals spanning much of the …
