Pantosaurus was a long-necked marine reptile that swam in a shallow sea that once covered part of North America. It was not a dinosaur, but a plesiosaur, a type of ocean predator. It used its four flippers to glide through the water and catch fish and other prey.1 2

Pantosaurus had a very long neck with between 35 and 40 neck bones, called cervical vertebrae. These bones were almost as long as they were wide, which helped make the neck flexible.3

The name Pantosaurus was originally 'Parasaurus', but that name was already used for another animal, so scientists changed it.1

Pantosaurus lived in the Sundance Sea, a shallow ocean that covered parts of Wyoming millions of years ago.1

Scientists think Pantosaurus might have given birth to live young, not laid eggs, because it lived in the water.2

The front flippers of Pantosaurus were special: the radius bone was much longer and broader than the ulna, which helped it steer in the water.3

A fossil of a baby ichthyosaur (a different marine reptile) was found inside a Pantosaurus stomach, showing it ate other marine reptiles.1

?What did Pantosaurus eat?

Pantosaurus ate fish and other marine reptiles. A fossil of a baby ichthyosaur was found inside a Pantosaurus stomach, showing it ate ichthyosaurs.1 3

?How big was Pantosaurus?

Pantosaurus was a small plesiosaur, but its exact size is not known from the sources. It had a very long neck with 35 to 40 neck bones.1 3

?When did Pantosaurus live?

Pantosaurus lived during the Late Jurassic period, about 163 to 157 million years ago.1 4

?Was Pantosaurus a dinosaur?

No, Pantosaurus was not a dinosaur. It was a plesiosaur, a type of marine reptile that lived in the ocean.1

Mosenyi wa ditshomo

Tshomo: Some people think Pantosaurus was a dinosaur because it lived in the same time as dinosaurs.

Nnete: Pantosaurus was a plesiosaur, a marine reptile, not a dinosaur. Dinosaurs lived on land, while Pantosaurus swam in the sea.1
