The nonmarine Glen Canyon Group in northern Arizona has the best known and most diverse assemblage of vertebrate fossils from the latest Triassic or Early Jurassic in North America. The purpose of this paper is to review the stratigraphic distributions of the vertebrate fossils within the group, especially those of the Moenave and Kayenta Formations and to interpret the implications of these distributions for the biostratigraphy of the group. -from Authors
