The Colorado Plateau and surrounding areas preserves one of the most extensive and complete examples of the terrestrial Triassic-Jurassic transition in North America, and arguably one of the best in the world. Rich in fossil resources, this region records a major, northwest-draining river system. In southwestern Utah, a wet, tropical, Late Triassic landscape slowly dried out and became, in the latest Triassic and Early Jurassic, an inland, Okavango Delta-like subtropical system that fluctuated between lake systems (Lake Dixie) and dry salt pans as ergs flanking the region to the east expanded and contracted. It is within this conceptual context that the geographic and temporal distribution of fossils can truly be understood and that the nature of the Triassic-Jurassic transition in the American Southwest can be appreciated.
