Who were DINOSAURS

They are basically termed the "terrible lizards". Dinosaurs were the land ruling replies whereas only 40% of them were carnivores. The common dinosaurs everyone knows are Triceratops, Tyrannosaurus rex, Parasaurolophus, Brontosaurus, Velociraptor(thanks to the Jurrasic Park franchise, although its body depicted is of a Deinonychus). But we misunderstand the Pterodactyls as dinosaurs whereas they aren't they are the species of the cousins of dinosaurs Pterosaurs. Even the Mosasaurus whereas they are a part of the genus Mosasaurs.
