'''Temnodontosaurus''' was an
ichthyosaur from the early
Jurassic found in
Europe (
England &
Germany) which grew to about 9 meters (30 ft) in length. Sometimes known as ''Leptopterygius'', this huge
ichthyosaur cruised the shallow seas, hunting large
squid and
ammonites. ''Temnodontosaurus'' eyes were approximately 20 cm (8 in) in diameter making them the largest of any known vertebrate.
