Picrocleidus was a plesiosaur, a long-necked marine reptile that swam in the Jurassic seas. It had a small head, a very long neck, and four flippers to paddle through the water. Picrocleidus was a meat-eater that hunted fish and other sea creatures.1 2

Utuntu dushimishije

Picrocleidus lived about 165 to 161 million years ago, during the Middle Jurassic period.2

The first Picrocleidus fossil was found in the Oxford Clay Formation in Peterborough, England.1

Picrocleidus was originally thought to be a species of another plesiosaur called Muraenosaurus, but scientists later gave it its own name.1

Five Picrocleidus specimens have been found, including one with a complete tail and another that was a young individual.1

The name Picrocleidus comes from Greek words meaning 'sharp key', because of its sharp, key-shaped collarbones.1

Picrocleidus is classified as a cryptoclidid, a group of plesiosaurs with long necks and small heads.1 2

Ivumburwa: The first Picrocleidus fossil was discovered in the Oxford Clay Formation in Peterborough, England, and was acquired by Alfred Nicholson Leeds. It was first named Muraenosaurus beloclis by Seeley in 1892, but Charles William Andrews gave it its own genus name Picrocleidus in 1910.1
Biracyagibwaho impaka: Scientists are not sure if Picrocleidus is really a separate genus from Muraenosaurus, or if they are the same animal.1
