|skeleton cast of Cryptoclidus
University of Tübingen
Cryptoclidus was a plesiosaur, an aquatic reptile up to 13 feet (4 m) long. It had curved, interlocking teeth, a wide skull, and large, flexible, paddle-like flippers. The fragile head and teeth could not deal with large prey. That suggests a diet of small, soft-bodied animals such as squid and small shoaling fish.
Cryptoclidus was named by Seeley in 1892. The type species is C. eurymerus.
