New Zealand Ichthyosaurs—a summary, including new records from the Cretaceous

Abstract

The bones reported from the Triassic of Mount Potts last century are indeterminable Ichthyosauria. No bones preserved in collections or seen on recent visits approach the large sizes reported by Hector. The names proposed for them by Hector, Lydekker and Chapman are either nomina nuda or were based on almost certainly non-diagnostic material which has subsequently been lost. Indeterminable ichthyosaurian centra from the Motuan Stage (Upper Albian) of Wairarapa district are the first Cretaceous ichthyosaurs to be reported from New Zealand.
