which is approximately above sea level. The high altitude of this site supports the idea that early Jurassic Antarctica had forests populated by a diverse range of species, at least along the coast. The Hanson Formation was deposited in an active volcano−tectonic rift system formed during the breakup of Gondwana. In the Early Jurassic, Antarctica was closer to the equator and the world was considerably warmer than today, but the climate was still cool temperate. Models of Jurassic air flow indicate that coastal areas probably never dropped much below freezing, although more extreme conditions existed inland. Cryolophosaurus was found about from the South Pole but, at the time it lived, this was about or so farther north. This formation has produced the remains of Glacialisaurus (a large basal sauropodomorph), a crow-sized pterosaur (a dimorphodontid), a synapsid (a tritylodont, which is a type of synapsid about the size of a rat), herbivorous synapsid, and two small unnamed sauropodomorphs. There are also the remains of many plant genera recovered from the Early Jurassic Camp Hill Formation, around the same age as fossils of Cryolophosaurus, proving that dense plant matter had once grown on Antarctica's surface before it drifted southward.
