Muraenosaurus (meaning "moray eel lizard") is an extinct genus of cryptoclidid plesiosaur reptile, from the Middle Jurassic of England and possibly France.

Description[edit]

M. leedsii
With a human to scale

Muraenosaurus grew to around 6 metres (20 ft) long, with around half of that length being taken up by the animal's neck, which possessed 44 vertebrae. Behind the neck, Muraenosaurus had a short, relatively inflexible body and powerful flippers. The head was remarkably small compared to the overall size of the animal, being only around 37 centimetres (15 in) long.[1][2][3]
