Carnivores

Kronosaurus

Spinosaurus

Pteranodon

Today, I'm going to talk about these three dinosaurs. Kronosaurus is the fiercest water creature that ever lived. The reason why I'm calling Kronosaurus a ''creature'' is because it's not a dinosaur. Dinosaurs don't fly or swim.The creatures that fly or swim are called ''reptiles.'' There are specific names and they're for flying creatures are Pterosaurs. The water creatures are Plesiosaurs. Dinosaurs only walk on land.Spinosaurus is a very big vicious predator. Velociraptor hunt in packs. They have one 7 inch claw  on each foot. A pack of Velociraptors can take down a Tyrannosaurus Rex.
