Ichthyosaurus

Genus of extinct marine reptile, type genus of Ichthyosauria

Ichthyosaurus (derived from Greek ἰχθύς (ichthys) meaning 'fish' and σαῦρος (sauros) meaning 'lizard') is an extinct genus of ichthyosaurs from the Early Jurassic (Hettangian - Pliensbachian) of Europe (Belgium, England, Germany and Portugal). Some specimens of the ichthyosaurid Protoichthyosaurus from England and Switzerland have been erroneously referred to this genus in the past. It is among the best known ichthyosaur genera, as it is the type genus of the order Ichthyosauria.
