Eurycleidus was a big, swimming reptile that lived in the sea during the Early Jurassic, about 200 million years ago. It was not a dinosaur, but a plesiosaur with a long body and strong flippers. It used its sharp, needle-like teeth to catch fish.1

Datu dibertigarriak

Eurycleidus had large shoulder bones, which gave it a powerful forward stroke for fast swimming.1

The first fossils were bought by Thomas Hawkins in the early 1830s from a quarry in Street, Somerset, England.1

In 1837, Richard Owen mistakenly thought the fossils came from Lyme Regis, but they actually came from Somerset.1

The species was first named Plesiosaurus arcuatus in 1840, and later renamed Eurycleidus in 1922.1

Some fossils that were once thought to be Eurycleidus were later moved to other genera, like Atychodracon and Lindwurmia.1

Eurycleidus lived in the sea and was an active swimmer, living near the surface.2

Eurycleidus: AAk egindako irudia — Eurycleidus nolakoa izan zitekeen erakusten duen AAk egindako irudia, ordenagailu batek zientzialariek dakitenetik sortua. Asmakizun bat da: benetako animalia desberdina izan zitekeen, eta inork ez daki zein ziren bere benetako koloreak.

Mito-hauslea

Mitoa: Eurycleidus was a dinosaur.

Egia: Eurycleidus was a plesiosaur, a marine reptile, not a dinosaur.1
