Natural History - Fossil Keichousaurus Skeleton

Item Details

Description

Triassic Period, 250-200 million years BP. A complete fossil Keichousaurus hui marine 'dinosaur' skeleton on matrix. 1.5 kg, 27.3cm (10 3/4"). From a Lincoln palaeontological collection; acquired 1970s-1980s; from Xingyi, Guizhou, China. Keichousaurus was a late-Triassic marine reptile and a member of the Pleurosaur family; it died out around 250 million years ago during the Triassic-Jurassic extinction event. They were specialised fish eaters, and were highly unusual amongst marine reptiles in that they gave birth to live young rather than laying eggs.
