Pantosaurus
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.12

Сонирхолтой баримтууд
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

- Pantosaurus was first found in Wyoming in the late 1800s by Othniel Charles Marsh. He named it Parasaurus in 1891, but changed the name to Pantosaurus in 1893 because the old name was already taken.13
- Маргаантай хэвээр
- Scientists still debate whether some fossils belong to Pantosaurus or to another similar plesiosaur, because the skull is not known.3
