Leptocleidus was a small plesiosaur that swam in shallow seas and rivers during the Early Cretaceous. It had a long neck, a short body, and four flippers to paddle through the water. Unlike many other plesiosaurs, it lived in lagoons and even brackish or fresh water.1

Leptocleidus had about 21 teeth on each side of its upper jaw and around 35 teeth on each side of its lower jaw.1

Its skull was triangle-shaped with a crest running from the tip of the nose to the nasal region.1

Unlike many plesiosaurs, Leptocleidus lived in shallow lagoons and may have entered brackish or fresh water, like river mouths.1

Scientists think Leptocleidus moved into fresh water to escape larger plesiosaurs and pliosaurs.1

The name Leptocleidus comes from Greek words meaning 'slender clavicle', referring to its thin collarbone.1

Leptocleidus had large clavicles and interclavicle bones but small shoulder blades, similar to the early Jurassic Rhomaleosaurus.1

A specimen from the Isle of Wight, once thought to be Leptocleidus, was later named a separate genus, Vectocleidus, in 2012.1

Las dumondas las pli frequentas davart Leptocleidus

?How big was Leptocleidus?

Leptocleidus was small for a plesiosaur, measuring up to 3 metres (9.8 feet) long. One species, Leptocleidus superstes, was even smaller at about 1.5 metres (5 feet).1 3

?Was Leptocleidus a dinosaur?

No, Leptocleidus was not a dinosaur. It was a plesiosaur, a type of extinct marine reptile that lived in the sea.1 3

?What did Leptocleidus eat?

Scientists are not sure exactly what Leptocleidus ate, but its many sharp teeth suggest it ate fish or other small sea creatures. It likely hunted in shallow waters.1 3

?Where did Leptocleidus live?

Leptocleidus lived in shallow lagoons and sometimes entered brackish or fresh water, like river mouths. Its fossils have been found in England, South Africa, and Australia.1 3
