Hastanectes was named in 2013 by scientists Benson, Ketchum, Naish, and Turner.3 1

Its name means 'spear swimmer' in Greek, because of its long, pointed snout.3

Hastanectes lived about 139 to 132 million years ago, during the Early Cretaceous.3

It was originally thought to be a species of Cimoliasaurus, another plesiosaur.1

Fossils of Hastanectes have been found in the Wadhurst Clay Formation of England and the Bückeberg Formation of Germany.3

Scientists are unsure if Hastanectes belongs to the plesiosaur family Leptocleididae or the pliosaur family Pliosauridae.3 1

Ammallee falmisiisaa: Scientists still debate whether Hastanectes is a leptocleidid plesiosaur or a pliosaur, because its fossils share features of both groups.3 1
