Ebyewuunyisa

Styxosaurus had an extremely long neck, with over 60 vertebrae, making it one of the longest necks of any animal that ever lived.2

It lived in the Western Interior Seaway, a huge inland sea that split North America in two during the time of the dinosaurs.2

Some fossils of Styxosaurus were once thought to belong to a different animal called Hydralmosaurus, but scientists now think they are the same.2

?What did Styxosaurus eat?

It ate fish, squid, and belemnites. It grabbed slippery prey with its sharp, interlocking teeth and swallowed it whole.4

?When did Styxosaurus live?

It lived during the Late Cretaceous period, about 100 to 72 million years ago.4 5

?Did Styxosaurus have a long neck?

Yes, it had an extremely long neck with over 60 vertebrae, making it one of the longest necks of any animal.4 2

?Is Styxosaurus a dinosaur?

No, it is a plesiosaur, a marine reptile that lived in the sea, not a dinosaur.4

?Where was Styxosaurus found?

Fossils have been found in North America, mainly in Kansas, South Dakota, Nebraska, and Wyoming, in rocks that were once the bottom of a shallow sea.4 5
