The name means ‘frozen crested reptile’ in reference to its polar occurrence and the unusual bony display crest on top of the skull. Large long-necked sauropod herbivores such as Apatosaurus and Brachiosaurus were also present along with the ﬂying reptiles, the pterosaurs, that co-existed with the dinosaurs during the Mesozoic. The success of the dinosaurs was quick and striking, and seems to have been associated with equally striking climate and ﬂoral changes. The Dicroidium ﬂora gave way to a conifer-dominated plant assemblage, which was to ﬂourish for much of the period of the dinosaurs.
