Leptocleidus

Leptocleidus is an extinct genus of pliosaurid plesiosaur, belonging to the family Leptocleididae. It is the only known pliosaur to be found in sediments on the Isle of Wight.

In short, the term Leptocleidus means "slender clavicle". It comes from a merge of the Greek words λεπτοσ, meaning "slender" and κλειδ (also spelled κλεισ) meaning clavicle.
