Rhaeticosaurus was a small, early plesiosaur that swam in the seas of the Late Triassic. It had four flippers shaped like wings and a long neck, and it used its flippers to fly through the water. This marine reptile is one of the oldest plesiosaurs ever found.2

1

Rhaeticosaurus is the first plesiosaur skeleton ever found from the Triassic period, showing that plesiosaurs were already around before the Jurassic.2

2

Its name means 'Rhaetian lizard' because it lived during the Rhaetian age, the last stage of the Triassic.1

3

Rhaeticosaurus had very short lower arm and leg bones compared to its upper limb bones, with a humerus-to-radius ratio of 3.8 and a femur-to-tibia ratio of 4.3.2

4

The holotype skeleton was discovered in 2013 by Michael Mertens, a private collector who reported it to authorities.1

5

Rhaeticosaurus was a basal member of the Pliosauridae, a group of plesiosaurs with large heads and short necks.2

6

Its teeth had sharp ridges on the enamel, a feature that helped scientists identify it as a plesiosaur.2
