Hastanectes was a plesiosaur, a marine reptile that lived in the seas around what is now England and Germany. It had a long neck, flippers, and a mouth full of teeth to catch fish. It swam in warm, shallow waters during the Early Cretaceous period.3 1

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

Chithunzi cha Hastanectes chopangidwa ndi AI — Chithunzi cha momwe Hastanectes mwina ankaonekera, chopangidwa ndi kompyuta kuchokera pa zomwe asayansi amadziwa. Ndi kungoyerekeza: nyama yeniyeniyo mwina inkaoneka mosiyana, ndipo palibe amene akudziwa mitundu yake yeniyeni.

Kupezeka: Hastanectes was first named in 2013 by a team of scientists who re-examined old fossils that had been called Cimoliasaurus valdensis since 1889. The fossils came from the Wadhurst Clay of England.1
Akukambiranabe: Scientists still debate whether Hastanectes is a leptocleidid plesiosaur or a pliosaur, because its fossils share features of both groups.3 1
