Cryonectes was a marine reptile that lived in the Early Jurassic seas, about 185 to 183 million years ago. It was a pliosaur, a type of plesiosaur with a big head and a short neck, built to hunt other sea creatures. Its fossils were found in Normandy, France.1 3

Cryonectes is known from a partial skull, lower jaw, and ten vertebrae, which were collected in the 1980s from a quarry in France.1

Its skull is about 47 centimeters (19 inches) long, making it a moderate-sized pliosaurid.1

The name Cryonectes means 'cold swimmer' because it lived during a cool period in the Early Jurassic.1

Cryonectes was a subadult when it died, as shown by its vertebrae having open growth plates.1

Its snout is very long, and the lower jaw has a long symphysis (where the two halves meet) with seven tooth positions.1

Scientists think Cryonectes is one of the earliest pliosaurids, helping to show that pliosaurids evolved earlier than previously thought.2

Nhunumu: Cryonectes was named in 2012 by Peggy Vincent, Nathalie Bardet, and Emanuela Mattioli based on a fossil found in the 1980s in Normandy, France. The fossil was stored at the Musée de l’Agglomération d’Elbeuff in Elbeuf-sur-Seine.1 2
Wɔda so gye ho akyinnye: Scientists are still debating exactly where Cryonectes fits in the pliosaur family tree, though it is thought to be a basal (early) pliosaurid.1 2
