Caudipteryx
Also known as the 'feathered dinosaur', its arms were covered in feathers and it had a fan-like tail, could grow up to 1 m in length and 0.7 m in height, had extremely large claws and its tail helped it balance while it attacked its prey
Scientists have found a way to measure the age of dinosaurs by studying their bones. They study the growth rings inside the fossilised bones, a technique similar to the one used to measure the age of trees. But it is not a foolproof method for all species because, in the case of some species, their bones grew continuously without any neat growth rings.
Brachiosaurus

Stegosaurus
A herbivore, also known as a 'roof lizard', had two rows of bony plates along its back, which helped it regulate its body temperature and also defend against carnivorous dinosaurs
