Abstract
Several hundred isolated anuran bones recovered from 37 localities in southern Utah, USA, provide a relatively continuous record of the evolution of anuran assemblages in the central part of the North American Western Interior that spans almost 25 million years, from the early Cenomanian to the late Campanian. Although it is difficult to associate isolated anuran bones from different parts of the skeleton with each other, it is possible to identify distinctive morphs for certain bones (e.g., ilia, maxillae) that can be used to make inferences about the taxonomic diversity of fossil assemblages.
