Tenontosaurus
Tenontosaurus meaning Tendon Lizard.
Judging by the number of remains that have been found,including 25 skeletons and
scattered bones and teeth,Tenontosaurus must have been one of the most abundant
herbivores in early Cretaceous North America. It was certainly attractive to meat-eaters. One skeleton has been found surrounded by the bodies of Deinonychus that had been killed while attacking it.
Tenontosaurus was the prey of the North American plains
Tenontosaurus is like a Hypsilophodontid but lacks the teeth on the front of the
jaw. Otherwise it is like an Iguanodontid but the classification is still not clear.
Its distinctive feature is it's very long tail-longer than the rest of the body-
and the network of tendons that supports the spine. It's long forelimbs and strong
finger bones suggest that it walked on all fours for most of the time.
