یوریسور

Eurysaurus (meaning "wide lizard") is an extinct genus of plesiosaur, originally classed as a nothosaur, from the Early Jurassic of Echenoz-la-Meline, France, named in 1878. The type material, consisting of a cranium, teeth and five vertebrae, is now lost. The type species is E. raincourti, and a second species, E. schafferi, was named in 1924 but it has since been absorbed into the unrelated genus Germanosaurus.
