Iguanodon was a large, bulky herbivore, measuring up to 9–11 metres (30–36 ft) in length and 4.5 metric tons (5.0 short tons) in body mass. Distinctive features include large thumb spikes, which were possibly used for defense against predators, combined with long prehensile fifth fingers able to forage for food.

Iguanodon was the largest, best known, and most widespread of all the iguanodontids (family Iguanodontidae), which are closely related to the hadrosaurs, or duck-billed dinosaurs. Iguanodon was 9 metres (30 feet) long, stood nearly 2 metres tall at the hip, and weighed four to five tons.

Iguanodontidae is a family of iguanodontians belonging to Styracosterna, a derived clade within Ankylopollexia. The clade is formally defined in the PhyloCode by Daniel Madzia and colleagues in 2021 as "the largest clade containing Iguanodon bernissartensis, but not …

2022年4月4日 · Iguanodon is a genus of extinct ornithopod dinosaur that lived around 135 and 125 million years ago. It was one of the three genera, along with Megalosaurus and Hylaeosaurus, used to describe clade Dinosauria.

It had a large thumb spike on the end of its hand, probably to fend-off predators, and the structure of the muscles inside its head suggest it had a very long tongue. Explore Iguanodon, a plant-eating ornithopod dinosaur in the Dino Directory.
