Iguanodon
Iguanodon was a large herbivorous dinosaur that lived during the late Jurassic to early Cretaceous periods, around 150 to 100 million years ago. It is known for its distinctive thumb spikes, which were likely used for defense and foraging. Iguanodon could walk on both two legs and four, making it a versatile dinosaur.
Fossils of Iguanodon have been found in Europe and North America, providing valuable insights into its behavior and environment. This dinosaur could grow up to 33 feet long and weighed around 3 to 5 tons. Its name means "iguana tooth," reflecting its tooth structure similar to that of modern iguanas.
