air flow indicate that coastal areas probably never dropped much below freezing, although more extreme conditions existed inland. Glacialisaurus was found about from the South Pole, which was about or so farther north at the time. This formation has yielded the remains of the large theropod Cryolophosaurus, a crow-sized dimorphodontid pterosaur, a rat-sized tritylodont synapsid, and two small unnamed sauropodomorphs. Many plant genera have also been recovered from the Shafer Peak section of the Hanson Formation that suggest forests similar to the open woodlands of North Island, New Zealand. Known plants include Cheirolepidiaceaen conifers, Equisetites horsetails, and Cladophlebis ferns that have also been found or are similar to plants found in other Early Jurassic sites that represent warm climates. Basal sauropodomorphs like Glacialisaurus were the first very large dinosaurs and, due to their height, the first herbivores to high browse.
