Vectocleidus

Say it: vek-toe-KLYE-dus
Name means: “Vectis (the Isle of Wight) + kleid- (key or collar bone), meaning 'Vectis collar bone'”1
Ate: MeatPlesiosaursEarly CretaceousNot technically a dinosaur

Vectocleidus was a plesiosaur, a long-necked marine reptile that swam in the warm seas of the Early Cretaceous. It lived about 125 million years ago near what is now the Isle of Wight in the United Kingdom. This predator used its sharp teeth to catch fish and other slippery prey.14

Fun fact: this sea reptile swam while dinosaurs walked on land. Everyone calls them dinos, but they were a different branch of reptiles.

Fun facts

1

Vectocleidus is known from only a single specimen, which includes parts of the skull, backbone, and flippers.1

2

It belonged to a group called Leptocleididae, which were small to medium-sized plesiosaurs that lived in shallow seas.14

3

The name Vectocleidus comes from Vectis, the ancient Roman name for the Isle of Wight, and the Greek word kleid- meaning 'key' or 'collar bone'.1

4

Its fossils were found in the Vectis Formation, which was once the bottom of a warm, shallow sea.14

5

Scientists think Vectocleidus was a fast swimmer that used its long neck to ambush prey.1

Myth buster

Myth: Vectocleidus is often mistaken for a dinosaur.

Truth: Vectocleidus was a plesiosaur, a marine reptile, not a dinosaur. Dinosaurs lived on land, while plesiosaurs swam in the oceans.1

Scientists are still debating exactly how Vectocleidus is related to other leptocleidid plesiosaurs, because its skeleton is incomplete.1
