The Newark Supergroup is a significant geological formation from the Late Triassic to Early Jurassic periods, located primarily in the eastern United States. It comprises a series of sedimentary rocks and volcanic deposits that provide crucial insights into the paleoenvironments and paleoclimate of the time. Its stratigraphy includes important fossil sites that have yielded evidence of early dinosaur evolution and the ecological changes associated with the transition from the Triassic to the Jurassic.
