Dinosaurs lived on Earth for around 160 million years, from the Triassic period to the Cretaceous period.
Not all dinosaurs were huge – some were the size of a chicken.
The largest dinosaur ever discovered was the Argentinosaurus, which was estimated to be around 100 feet long and weigh around 100 tons.
The smallest known dinosaur was the Microraptor, which was only about the size of a sparrow.
The T-Rex had teeth that were up to 12 inches long.
Some dinosaurs were feathered, such as the Velociraptor and the Microraptor.
The Stegosaurus had bony plates on its back that may have been used for thermoregulation or as a form of protection.
The Triceratops had three horns on its head, one above each eye and one on its snout.
The Brontosaurus is not a real dinosaur, it was a mistaken identity for the Apatosaurus.
The extinction of dinosaurs is believed to have been caused by an asteroid impact, which created a dust cloud that blocked out sunlight and caused a mass extinction event.
Dinosaurs are a fascinating and mysterious subject, with many interesting facts and theories still being discovered today. From the giant Argentinosaurus to the tiny Microraptor, there was a great diversity among dinosaurs, and they continue to capture the imagination of people of all ages.
