A jaw and teeth belonging to an Albertosaurus were identified by
Joseph Leidy, who named the first American dinosaurs.
Directions:
Write
a descriptive essay about being a Albertosaurus living in a
particular region. What would the eat dinosaur eat; would it be a
meat eater or a plant eater? How big would it be? What would it look
like? What kind of plants and other animals/dinosaurs would be there?
What would the weather be like? Would it be warm, hot or cool? Would
the climate be wet or dry? What other details would you like to add?

to help them dive.

Velociraptor Information
Translation:
Speedy Thief
Diet:
