South Polar region of the Cretaceous diversity terrestrial flora and fauna of the Late Cretaceous polar region. Seymour Island is similar in this respect, the area of discovery for vertebrate and invertebrate creatures–such as plesiosaurs–of the Late Cretaceous, extending into the Eocene. Other Cretaceous fossil-bearing formations in Antarctica are the Snow Hill Island Formation, the Lopez de Bertodano Formation, and the Hidden Lake Formation, also on James Ross Island. The Eumeralla Formation of Dinosaur Cove and the Wonthaggi Formation in Victoria, Australia, contain a number of dinosaur fossils and tracks from the Early Cretaceous. The Tahora Formation represents the reptile assemblage of Cretaceous New Zealand. The
