Plesiopterys
Plesiopterys was a small, long-necked marine reptile that swam in the warm seas of Early Jurassic Germany. It had flippers like paddles and a mouth full of sharp teeth for catching fish and squid.1

Prettige feite
Plesiopterys had 39 neck vertebrae, giving it a long, flexible neck.2
One fossil of Plesiopterys preserves traces of scaly skin on its front flipper and smooth skin on its tail.1
The tail skin of that fossil also contains dark-colored melanosomes, which are pigment cells that may have given the animal a dark color.1
Plesiopterys is one of the most primitive plesiosaurs known, meaning it had many features from earlier ancestors.2
Its skull was small compared to its neck, only about 17 percent of the neck length.2
The name Plesiopterys also refers to the pterygoid bones in the roof of its mouth, which are important for identifying the species.1
