First up, meet the Iguanodon. This dinosaur’s name means “iguana tooth” because its teeth looked a lot like those of an iguana! The Iguanodon was one of the first dinosaurs ever discovered. It was pretty big, walked on two legs, and had thumb spikes. Scientists think these spikes could have been used for defense or to help them find food.

Then there’s the incredible Irritator. Yes, that’s really its name! The Irritator was a meat-eating dinosaur and got its funny name because the scientists who found its fossil were irritated by how hard it was to clean the rock off its bones. Imagine being named after someone’s bad day!

And don’t forget about the Ichthyosaurus, which wasn’t exactly a dinosaur but lived at the same time. Its name means “fish lizard,” and it looked a lot like a big fish or a dolphin. The Ichthyosaurus was a great swimmer and lived in the ocean, catching fish and squid.
