Let's look at a typical Tenontosaurus image by Raul Martin.

Tenontosaurus lived along that coast of inland sea we know of that stretched through the heartland of America. It had a grasping hand but lacked the enormous thumb spike of its cousin the Iguanodon. This image, therefore, is not sculpted correctly as the hand is actually quite slender and the five fingers actually show a bit of articulation, enough to grasp plant matter at the very least. However, as far as dinosaur safaris go, it is an interesting piece.
