Iguanodon was a large herbivorous dinosaur from the Early Cretaceous period. Imagine a giant iguana, but much, much bigger! 🦖 It was one of the first dinosaurs ever discovered and helped shape our understanding of these ancient creatures. It had strong hind legs, smaller arms, and a distinctive thumb spike, probably used for defense. They roamed across what is now Europe and North America. Think of it as a prehistoric cow, peacefully munching plants. Iguanodons teach us about the diverse forms dinosaurs took.
