Top 10 facts on dinosaurs
1. Dinosaurs roamed the Earth for over 160 million years, from the Late Triassic period to the end of the Cretaceous period.
2. The largest dinosaur ever discovered is Argentinosaurus, weighing around 100 tons and measuring up to 100 feet long.
3. Velociraptors, made famous by movies like Jurassic Park, were actually about the size of a turkey, much smaller than portrayed in the films.

7. The oldest known dinosaur is Nyasasaurus, dating back to around 243 million years ago.
8. Birds are considered modern-day dinosaurs, as they share a common ancestry with certain small, feathered dinosaurs.
9. The Stegosaurus had a brain the size of a walnut, one of the smallest brain-to-body ratios among dinosaurs.
10. The extinction of dinosaurs 66 million years ago is thought to be caused by a combination of a massive asteroid impact and volcanic activity.
Certainly! Here are ten fascinating facts about dinosaurs:
1. **Dinosaurs lived on Earth for over 165 million years:** They roamed the planet during the Mesozoic Era, from about 230 million years ago to 65 million years ago.
2. **Tyrannosaurus Rex had a bite force of about 8,000 pounds:** This made it one of the most powerful land predators in history.
