Abstract:
Preliminary assessment of the taphonomy of these assemblages reveals a pattern in their preservation: dinosaurs and non-phytosaurian and aetosaurian pseudosuchians are common in blue floodplain paleosols, whereas phytosaurs, aetosaurs, and metoposaurs occur in most facies and are common in red- and grey-hued floodplain deposits. The restriction of dinosaurs to particular facies may be a major factor influencing our understanding of dinosaur diversification relative to that of other vertebrate faunas in the Late Triassic. The differing faunal assemblages and their association with particular facies suggest that preservation, along with evolution, likely influenced the biostratigraphic distribution of Chinle vertebrates.
