Paleoecology Of Early Jurassic Navajo Sandstone Interdune Deposits, Nathan Daniel Wilkens
Paleoecology Of Early Jurassic Navajo Sandstone Interdune Deposits, Nathan Daniel Wilkens
Canyonlands Research Bibliography
The Lower Jurassic Navajo Sandstone represents a desert that covered more than 366,000 square kilometers. Localized interdune deposits commonly occur along the eastern edge of this desert that include carbonates, bioturbated layers, and plant fossils. Previous studies of these deposits focused on specific fossil types or isolated sites. This study involved a comprehensive analysis of the paleoecology of interdune deposits with an integrated approach combining paleontology, sedimentology and geochemistry. The methods used in this study were devised to test specific paleoecological and preservational questions, including water sources and geochemistry, sedimentation mechanisms, fossil identification and paleoecology, taphonomy, and diagenesis. Three hypotheses …
