About Niobrarasaurus
What it was like
Niobrarasaurus was a nodosaur, an armored plant eater with bony plates on its back and no tail club.
Its world
It lived about 90 to 84 million years ago, in the Late Cretaceous, in what is now Kansas. Its bones come from the Niobrara Formation, which formed in the Western Interior Seaway far from land. Its body probably floated out to sea after death, like that of the duckbill relative Claosaurus from the same rocks.
How it was found
Carpenter and colleagues named it in 1995. There are two recorded finds.
