Descriptive anatomy of the largest known specimen of Protoichthyosaurus prostaxalis

Representing one of the first times that medical imaging and three-dimensional reconstruction methods have been applied to a large skull of a marine reptile, researchers describe the partial skeleton of a large ichthyosaur from the Lower Jurassic of Warwickshire, England. The unusual three-dimensional preservation of the specimen permitted computed tomography (CT) scanning of individual braincase elements as well as the entire reassembled skull.
