Before us is the skeleton of a plesiosaur, a marine reptile, mounted as though the animal were swimming through open water. The long, narrow skull with its row of small teeth gives way to a spine with ribs, while four long flippers spread out to either side. The bones of the "fingers" are preserved within the flippers. The animal measures between two and a half and three metres in length.

Dolichorhynchops was a marine reptile, not a dinosaur: a short-necked plesiosaur of the Cretaceous period belonging to the family Polycotylidae. Its elongated snout was adapted for catching fish and cephalopods. Its four flippers worked as underwater wings: the animal did not row but flew through the water. It breathed air and rose regularly to the surface.

The skeleton's value lies in its completeness: the skull and all four flippers belong to a single animal. It reveals how this swimmer was built, from the narrow snout to the last bones of the "fingers". In space it reads as motion, arrested mid-stroke.

In life

Dolichorhynchops hunted in open water, beating its flippers like wings, and rose to the surface for a breath of air.
