"Hooooo! Indeed, hootie hoo! I couldn't possibly be more enthused! Hoo hoo! The iguanodon holds the distinction of being the first dinosaur ever found! Until this beast was found, we were unaware that dinosaurs even existed, wot! One wonders if the first iguanodon tooth found was thought to be an iguana's! Ah. Hoo, terribly sorry. I went on a tangent again, didn't I? Hoo, sorry!"

"The spikes that look like spears are characteristic of the iguanodon, eh wot? When it was first found, it was actually thought to be a giant iguana because of the shape of its teeth. Indeed, that's how it got its name. It was also thought that it would fight off predators with its spikes... Any way one slices it, all signs point to this beast being one mobile, tough, herbivorous dinosaur!"

"The iguanodon is so named because it was mistakenly believed to be a large iguana. An herbivore, it is famous for its spikelike thumb claws, which seem somewhat odd on a nonpredator. Supposedly it would run on two legs but would use all four when it was just walking at its leisure."

"Ah, that graceful ballerina of the Cretaceous, the Iguanodon! When I say it was graceful, I mean by the...ahem...rather low bar set by other large herbivores. Apparently it would nimbly dodge the attacks of predators and fight back with its thumb claws! It could even walk on two legs when it wanted to! Er...truly it was the most elegant and lithe of the dinosaurs."

In Real Life
Iguanodon was an herbivorous ornithopod dinosaur which lived in Europe. It is one of the first named genera of dinosaur, described by Gideon Mantell in 1824 and named by Friedrich Holl in 1829. While multiple species ranging from the Late Jurassic to Early Cretaceous have historically been classified as Iguanodon, reclassification efforts during the 21st century limited the genus to only two species living 126-122 million years ago in the Early Cretaceous. It was up to 10 meters long, weighed 3 tons, and sported a beak with iguana-like teeth (hence the name). Its most notable anatomical feature was a thumb spike, which Mantell originally misinterpreted as a horn on the nose.
