Ichthyosaurs

Eurhinosaurus longirostris

Posidonia Shale, Early Jurassic: Toarcian,
approx. 180 Mio. years old
Ohmden, Baden-Württemberg, Germany

Ichthyosaurs were the most widely adapted group of reptiles to life in water. The body is streamlined, the arms and legs have been transformed into paddles, and the animals possessed a fish-like tail fin and a dorsal fin similar to a dolphin. They were apparently inhabitants of the open oceans and fed on fish, squid, and probably smaller marine reptiles.
