Edgarosaurus was a short-necked plesiosaur that swam in the warm, shallow sea that once covered Montana. It used its long snout and sharp teeth to catch fish and other slippery prey.12

1

Edgarosaurus had a short neck and a long snout, unlike the long-necked plesiosaurs like Elasmosaurus.1

2

Its skull is one of the oldest and best-preserved plesiosaur skulls from the Cretaceous of North America.1

3

Edgarosaurus had 26 neck bones, which is more than some other short-necked plesiosaurs like Dolichorhynchops (which had 19).2

4

It had a small opening in the top of its skull called a pineal foramen, which some other plesiosaurs lacked.2

5

The only known fossil of Edgarosaurus was found in the Thermopolis Shale, which was once the bottom of the Western Interior Seaway.1

6

Edgarosaurus lived about 106 to 94 million years ago, during the Late Cretaceous period.2

Edgarosaurus was named by Pat S. Druckenmiller in 2002, based on a partial skeleton found in Montana. The type specimen includes a complete skull, many vertebrae, and a forelimb.13
ገና ዘከራኽር
Scientists are not sure exactly how Edgarosaurus is related to other plesiosaurs. Some place it in the group Polycotylidae, but its exact family tree is still debated.1
