Pararcus was a marine reptile that lived in the shallow seas of the Netherlands about 245 million years ago. It had a flat body and strong, paddle-like limbs for swimming. Unlike many other placodonts, it did not have a heavy shell on its back.12

1

Pararcus had a special backbone where the neural arches (the parts that protect the spinal cord) were not fused together, even in adults. This is called paedomorphosis and is common in animals that live in the sea.1

2

Its hip bones (pubis and ischium) were flat and plate-like, which helped it swim efficiently.1

3

The only known fossil of Pararcus was found by a fossil collector named Gerben Diepenbroek, and the species is named after him.1

4

Pararcus lived during the Middle Triassic period, about 247 to 241 million years ago, when the Netherlands was covered by a shallow sea.2

5

Unlike some other placodonts that had heavy armour plates, Pararcus only had a few small, unfused armour plates scattered in its skin.1

6

The vertebrae of Pararcus were deeply hollowed out on both ends (amphicoelous) and still had a notochord, a flexible rod that runs through the spine.1

Pararcus was named in 2014 by Nicole Klein and Torsten Scheyer. The only fossil was found by Gerben Diepenbroek in a quarry near Winterswijk, the Netherlands.21
E sa ntse e phehwa kgang
Scientists are not sure exactly how Pararcus swam. Its flexible backbone and flat hip bones suggest it might have moved differently from other placodonts.1
