Tenontosaurus was a hyphsilodont dinosaur from the early Cretaceous North America.


Tenontosaurus was a dinosaur who shared the traits of both iguanodonts (i.e. Iguanodon) and smaller hypsilophodonts (i.e. Leaellynasaura), but it indeed the most basal iguanodont. It reached up to 6.5 m in length and in many ways it was the cow of the Cretaceous. It didn't have many means of self-defence besides its size and relatively powerful tail - longer than the rest of its body and built like a two-by-four board - and it was popular prey for many carnivores, including Acrocanthosaurus and Dromaeosaurus, because of its relatively small size.
