The Jurassic period occurred around 150-200 million years ago. It was home to many iconic dinosaurs like the Archaeopteryx, Dilophosaurus, Brachiosaurus, and Stegosaurus. The Archaeopteryx was an early bird that lived in Germany and may have been able to fly or glide. The Dilophosaurus was a speedy carnivore that lived in Arizona. The huge herbivorous Brachiosaurus lived in Colorado and Tanzania. Finally, the armored Stegosaurus inhabited Wyoming and Utah. The Jurassic period eventually ended, making way for the Cretaceous period.

2. What is the Jurassic
period?
Cretaceous period came up next after the

3. Meet the Archaeopteryx

possible link between reptiles and birds.
 Paleontologists are debating if this bird could fly or have merely
glided from tree to tree.
 It ate mammals, lizards, insects, and fish.
 Its size was 14 inches long.
 It lived in Germany 150 million years ago.
 It ran, leaped, glided, and flapped.
 In any event it actually seems, that it was not a strong flier.
