       Discovered in New Zealand,‭ ‬Mauisaurus was for a long time credited as one of the largest plesiosaurs.‭ ‬However in more recent times there have been doubts about the validity of fossils attributed to the genus since these have come from so many different locations.‭ ‬Mauisaurus also displays the long sharp teeth often seen in elasmosaurid plesiosaurs that would have been ideally suited for snaring slippery fast moving prey.
       Mauisaurus‭ ‬was the first plesiosaur known from‭ ‬New Zealand,‭ ‬but a second called Tuarangisaurus has since been discovered.
