Abstract The Upper Triassic Chinle Formation is a critical non-marine archive of low-
paleolatitude biotic and environmental change in southwestern North America. The well …

Pycnodont fishes were a successful clade of neopterygian fishes that are predominantly
found in shallow marine deposits. However, throughout their long 180 million year reign …

Understanding how biodiversity has changed through time and space is a central aim of
paleobiology. To elucidate accurate biodiversity patterns in deep time, regional case …

Intensifying macrovertebrate reconnaissance together with refined age-dating of mid-
Cretaceous assemblages in recent decades is producing a more nuanced understanding of …

Over the past 30 years, exploration of the terrestrial Mesozoic section in Utah has resulted in
a more than five-fold increase in the known species of dinosaurs. A highly resolved temporal …

Although intensified work on the volcaniclastic-rich sediments of the fossil-bearing
Mussentuchit Member (uppermost Cedar Mountain Formation, Utah) has provided a refined …

Abstract The Early Cretaceous is an important time of transition in Earth history, marked by a
succession of oceanic anoxic events and carbon cycle perturbations that drove changes on …

Presented here is a coupled model of the nonmarine fossil record, based on a geometric
model of deposition, a random-branching model of evolution, and an ecological model …

Detangling the pace and structure of biotic turnover between the late Early and early Late
Cretaceous within the Western Interior of North America requires refined stratigraphic …

Current investigations into the Albian–Cenomanian sedimentary record within the Western
Interior have identified multiple complex tectono‐sedimentary process–response systems …
