Iguanodon tooth #1
Iguanodon is the first dinosaur ever discovered. The best cast replica tooth comes from an Iguanodon.
The cast replica measures approximately 2.5 inches
Iguanodon orientalis
Iguanodon means "Iguana tooth". It is classified as: Ornithopoda; Iguanodontia; Iguanodontidae
Early Cretaceous
Its hands had four fingers and a spike-like thumb, which it may have used to defend itself. Its teeth are reminiscent of those in hypsilophodonts, flattened side to side, and leaf-shaped. They probably sliced up plant material like a pair of scissors.
Because of the large number of skeletons of these dinosaurs frequently found together and evidence from fossil trackways, paleontologists think they may have formed herds. Their remains are most often found in sediments deposited in swampy, lake, and river edge environments suggesting that is the place they spent most of their time munching on horsetails (like the living Equisetum), ferns, cycads, and various kinds of conifers.
