Answer
During early Jurassic time, the climate of the present-day American Southwest was generally warm and arid. The region was part of the supercontinent Pangaea, which had a global monsoonal climate. The American Southwest experienced seasonal rainfall patterns with distinct wet and dry seasons. Rivers and streams flowed through the region, creating lush floodplains and supporting diverse ecosystems. In some areas, there were shallow seas, where marine life thrived. The climate and environment during the early Jurassic contributed to the development of diverse flora and fauna, including dinosaurs, early mammals, and various plant species.
