Diversity Patterns of Nonmarine Cretaceous Vertebrates of the Western Interior Basin,ding the distribution of nonmarine vertebrate orders, families, and genera spanning the Barremian through Maastrichtian stages of the Cretaceous. The Western Interior to date has not yielded any unequivocal records of older Cretaceous vertebrates. Nonetheless, these faunas span the remarkable develo

Limestone Concretions as Near-Isochronous Surfaces,l, smaller, but they are still much thicker and more prevalent than contemporary ashes. Establishing a high-resolution chronostratigraphic framework is becoming increasingly viable as more detailed stratigraphic sections are measured and described, a process well underway within the Cretaceous depos

The Limits of Paleontological Resolution,n be recognized vertically, traced laterally, and correlated using approaches such as biostratigraphy or sequence stratigraphy. However, the term “resolution” can also denote . of the physical records (e.g., fossils, grains, diagenetic precipitates, etc.) contained within individual strata. Due to t
