1. **Dino Names**: Dinosaurs had fascinating names like Brachiosaurus, Tyrannosaurus Rex, and Stegosaurus. These names often describe their features, such as their long necks or sharp teeth.
2. **Long Ago**: Dinosaurs lived a very long time ago, over 65 million years ago! They roamed the Earth during the Mesozoic Era.
3. **T-Rex: Tiny Arms**: Despite being enormous, the Tyrannosaurus Rex had very small arms, about the size of a human's. Scientists are still trying to figure out why!
4. **Herbivores and Carnivores**: Some dinosaurs were plant-eaters (herbivores), while others were meat-eaters (carnivores). The Brachiosaurus was a herbivore, while the Velociraptor was a carnivore.
5. **Extinction Mystery**: Scientists believe that a huge asteroid impact, volcanic activity, or climate change may have caused the mass extinction of dinosaurs. However, birds are considered the modern descendants of dinosaurs, so they're not entirely extinct!
