Fossil frogs from the early Campanian of West Texas, USA, with comments on Late Cretaceous anuran diversity in southern Laramidia

Palaeobiodiversity and Palaeoenvironments, 2021
A rare early Campanian (Aquilan) assemblage consisting of disarticulated anuran bones is described from the Aguja Formation of West Texas, USA. Many specimens within the assemblage pertain to taxonomically informative elements (maxillae, urostyles, and ilia).

Refined geochronology and revised stratigraphic nomenclature of the Upper Cretaceous Wahweap Formation, Utah, U.S.A. and the age of early Campanian vertebrates from southern Laramidia

Palaeogeography, Palaeoclimatology, Palaeoecology, 2022
The Western Interior of North America preserves one of the most complete successions of Upper Cretaceous marine and non-marine strata in the world; among these, the Cenomanian-Campanian units of the Kaiparowits Plateau in southern Utah are a critical archive of terrestrial environments and biotas.

A new chasmosaurine from northern Laramidia expands frill disparity in ceratopsid dinosaurs

Naturwissenschaften, 2014
A new taxon of chasmosaurine ceratopsid demonstrates unexpected disparity in parietosquamosal frill shape among ceratopsid dinosaurs early in their evolutionary radiation. The new taxon is described based on two apomorphic squamosals collected from approximately time equivalent (approximately 77 million years old) sections of the upper Judith River ...
