iguanodons

Iguanodons are a genus of herbivorous ornithopod dinosaurs that lived during the Late Cretaceous period, approximately 112 to 93 million years ago. They are known from fossils found in Europe, Asia, and North America. Iguanodons are characterized by their distinctive, duck-billed snouts, which were likely used for grazing on low-growing vegetation. Their teeth were continuously replaced throughout their lives, a feature known as polyphyodonty.

Iguanodons were medium to large-sized dinosaurs, with some species reaching lengths of up to 10 meters (33 feet) and weighing over a ton. They had a robust body, short limbs, and a long, whip-like tail. Their legs were positioned far back on the body, which allowed them to move quickly and efficiently over long distances.

Iguanodons are one of the most well-known and well-studied dinosaurs, with numerous species described from various locations. Some of the most well-known species include Iguanodon bernissartensis, Iguanodon ottingeri, and Iguanodon mantelli. Despite their popularity in popular culture, iguanodons were not the dominant herbivores of their time; they coexisted with other large herbivorous dinosaurs such as hadrosaurs and ceratopsians.

The name "Iguanodon" comes from the Greek words "iguanos," meaning "iguana," and "odon," meaning "tooth," reflecting the dinosaur's distinctive duck-billed snout. Iguanodons are an important part of the fossil record, providing valuable insights into the evolution and ecology of Late Cretaceous ecosystems.
