Hello my name is Finneas, and I'm an expert on dinosaurs. Dinosaurs can be tall as a house or short as a coffee table. Next I will tell you about the types of dinosaurs.

            Coelophysis is a small agile dinosaur that hunts in packs. If a full grown man ever stood next to this dinosaur, it would be level with his waist, but it's still very scary. Plateosaurus is a bigger slower dinosaur that is taller than a full grown man. It can stand on its hind legs if necessary to reach the leafy greens on top of the trees. Antetonitrus is taller than a grown man and lived around the end of the Triassic. Its name means before the thunder because it came before the bigger sauropods also known as the thunder lizards.

            Many dinosaurs live in groups or herds for safety. They do this for safety because if there are  a lot of you an enemy will think twice before attacking. It also helps protect the young because they can stay in the center of the group with the stronger grownups protecting them. A disadvantage to living in a herd is that they eat everything quicker. This means they have to migrate more often and cross rivers which is dangerous because if the river floods it will drown and kill most of them.

Dinosaurs have many styles of communication. Some use body language like pecking the ground, and others can produce sounds as loud as a dog's bark or a cat's howl. These dinosaurs are called Crested Duckbills. These creatures can make these sounds because of their special skulls. Their nasal cavity is attached to tubes heading up to an air space in the top of the crest. When they breathe in, the air flows through the tubes and produces the noise.

            If you could stop the dinosaurs from doing extinct, would you? Although we don't want dinosaurs wandering around the streets, they are still interesting. Paleontologists are digging up new dinosaurs every year.
