Picrocleidus

Naam beteken: “sharp key”1

Het geëet: VleisPlesiosourusseMiddel-JuraTegnies nie 'n dinosourus nie

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

Prettige feit: hierdie seereptiel het geswem terwyl dinosourusse op land geloop het. Almal noem hulle dino's, maar hulle was 'n ander tak van die reptiele.

Prettige feite

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

KI-prent van Picrocleidus — 'n KI-prent van hoe Picrocleidus dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Vir dino-kenners

Wetenskaplike naam: Picrocleidus
Benoem deur: Andrews 19092
Groep: Plesiosourusse
Familie / klade: Cryptoclididae2
Klassifikasie: Plesiosauria > Sauropterygia2
Ouderdom van die rotse: 165 tot 162 miljoen jaar (Callovian)2
Rotsformasies: Oxford Clay2
Lande: Verenigde Koninkryk2
Fossielrekords: 1 in The Paleobiology Database2
Ontdekking: 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
Steeds omstrede: Scientists are not sure if Picrocleidus is really a separate genus from Muraenosaurus, or if they are the same animal.1
