Plesiosaurus
Plesiosaurus was a marine reptile that swam in the oceans while dinosaurs lived on land. It had a long neck, a small head, and four flipper-like limbs to push through the water. It was about 3.5 metres long and ate small prey like fish and crustaceans.1

Fakte argëtuese
Plesiosaurus was named in 1821 by William Conybeare and Henry Thomas De la Beche, and the name means 'near reptile'.1
Mary Anning discovered an almost complete Plesiosaurus skeleton in 1823, which helped scientists understand what these animals looked like.1
Plesiosaurs swam with four flipper-like limbs, and experiments with robot flippers showed they could generate 60% more thrust from their back flipper by timing both limbs carefully.1
Plesiosaurs were unable to return to land, so they likely gave birth to live young in the open water, as supported by a preserved foetus in a related species.1
Plesiosaurs survived for more than 140 million years, making it through multiple extinctions that wiped out other groups.1
Some plesiosaurs swallowed stones that stayed in their stomachs, possibly to help break up food or to help with buoyancy.1
