Although the evidence is rare, fossils reveal that there were Mesozoic reptiles, including dinosaurs in New Zealand.
Possibly because it lacks the right conditions for fossilization, only fragmentary dinosaur remains have been found there.
Therefore, some fossils of marine reptiles are complete enough to be assigned to a specific genus or species.
So far, there have been fossils found in New Zealand that have been identified as coming from: Dinosaurs that lived in the Ross Dependency, a part of Antarctica within the Realm of New Zealand, include the tetanuran Cryolophosaurus.
Newer fossils from a Cretaceous-Paleogene boundary fossil formation known as the Takatika Grit in the Chatham Islands include six or seven (possibly more) bones from dinosaurs, as well as numerous bones from early birds, but more information is needed about these to add them to the list.
