Eurhinosaurus

Eurhinosaurus (Greek for 'well-nosed lizard'- eu meaning 'well or good', rhino meaning 'nose' and sauros meaning 'lizard') is an extinct genus of ichthyosaur from the Early Jurassic (Toarcian), ranging between 183 and 175 million years. Fossils of the aquatic reptile have been found in Western Europe (England, southern and northern Germany, the Benelux, France and Switzerland). They used to live in the deep, open sea area. Eurhinosaurus was a large genus of ichthyosaurs. An adult individual could reach up to 7 metres (23 ft) in length.

Eurhinosaurus followed the regular body morphology, with a fish-like fusiform body including well developed dorsal fin, hypocercal caudal fin, paired pectoral and pelvic fins, and remarkably large eyes. Like other ichthyosaurs, Eurhinosaurus did not have gills and used lungs for breathing. Eurhinosaurus had one distinct feature different from other ichthyosaurs: the upper jaw was twice as long as the lower jaw and covered with up and downwards-pointing teeth.
