Cryonectes
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.13

Datos curiosos
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

- Descubrimento
- 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.12
- Aínda en debate
- Scientists are still debating exactly where Cryonectes fits in the pliosaur family tree, though it is thought to be a basal (early) pliosaurid.12
