Alzadasaurus was a long-necked marine reptile that swam in the seas of North America about 80 million years ago. It was not a dinosaur, but a plesiosaur, and it used its four flippers to paddle through the water. With sharp teeth, it hunted fish and other sea creatures.4

Alzadasaurus lived during the Late Cretaceous period, between about 83.6 and 72.2 million years ago.1
It belonged to a group of plesiosaurs called elasmosaurids, which had very long necks.4
Fossils of Alzadasaurus have been found in the Bearpaw Shale formation in Montana.4
Some scientists think Alzadasaurus might actually be the same animal as Thalassomedon, another elasmosaurid.4
Alzadasaurus was named by paleontologist Samuel Paul Welles in 1943.4
It is the type genus of the subfamily Alzadasaurinae, a group of elasmosaurids.4
