From the WWD glossary:
Literally "flying reptile". These creatures were distinct from dinosaurs, none of which ever flew.
A group of air breathing, scaly-bodied animals with back bones that evolved from the amphibians. They fertilise their eggs internally and are not reliant on water to lay their eggs in. Modern turtles, crocodiles, lizards and snakes are all reptiles.
This huge two legged carnivore lived in the Late Cretaceous period. It roamed around the forests and marshes searching for prey. Its long, serrated teeth and enormous jaw made it a fearsome predator.
Settles a great deal.
