Product Description

This holotype specimen is the first relatively complete plesiosaur described from Canada. The genuine fossil pectoral and pelvic girdles, along with many of the limb bones, were exhibited at the Museum’s former location, and have been on display in Winnipeg almost continuously since 1934. Carnivorous plesiosaurs were amongst the most successful marine reptiles. They evolved in the Triassic Period, about 240 million years ago, and probably survived until the end of the Cretaceous Period, 65.5 million years ago. Using two pairs of flippers, plesiosaurs could navigate slowly, like large sea turtles.
