Background Info:
Dinosaurs dominated the earth for over 140 million years. They came in
many different shapes and sizes, and could live in a variety of land
ecosystems. While there are many different
types of prehistoric reptiles, dinosaurs are set
apart because they had back legs that were
straight under their bodies (like those of their
cousins, birds!). This type of leg placement that
differed from lizards and crocodiles allowed
them to use less energy when they moved.
Like other reptiles, dinosaurs laid eggs and had
a hole between their eye socket and nostril.
They also have two holes behind the eye socket on their skull where large, strong jaw muscles
would attach to the top of their skull, allowing them to open their jaw wide and bite down with
large amounts of force.
While a pterodactyl is one of our plates to make, they are NOT dinosaurs-they lived in the air
and are called pterosaurs!
