Historical and Ecological Biogeography of Nearctic Pikas (Lagomorpha: Ochotonidae)
Allozymic patterns among populations of Ochotona princeps indicate a pre-Wisconsin (> 120,000 years ago) divergence of four major genetic units in the western United States (northern Rocky Mountains,Expand
THE KIRTLANDIAN LAND-VERTEBRATE "AGE"—FAUNAL COMPOSITION, TEMPORAL POSITION AND BIOSTRATIGRAPHIC CORRELATION IN THE NONMARINE UPPER CRETACEOUS OF WESTERN NORTH AMERICA
The Kirtlandian land-vertebrate “age” (LVA) is equivalent to 2.2 million years of Campanian time and fills a long-standing biochronologic gap between the Judithian and Edmontonian LVAs. TheExpand
Late Triassic dinosaursfrom the western United States
Western North America has one of the most extensive fossil records of Late Triassic dinosaurs. AllUpper Triassic strata are assigned to the Chinle Group which yields four successive, dinosaur-bearingExpand
