Bob discovered in the beginning there were only tiny life forms. These tiny lines in the rock are actually fossils.
Bob learned that at one time most of the earth was covered with water.
He wondered about the types of sea creatures that once swam here.
Would they have eaten dogs?
some of the first sea creatures
right where he was standing!
Amazed, Bob moved further through time and discovered the first plants were much larger than what is on earth today.
And so were the bugs!!
This is a gigantic Arthropod!
It lived around 354 - 290
million years ago!
Bob is staying out of it's way!!
Bob moved quickly away from the Huge creature and right in the path of a Parasauroloplus!
The Parasuroloplus might be a plant eater, but Bob wasn't going to take any chances!
He jumped out of the giant's mouth and into a raptor's claws!
Lucky for Bob the raptor was looking the other way .
Bob was able to jump out of his claws, but uh oh!
Now Bob is being chased by a Herrerasaurus! Run Bob run!
Bob finally found a friendly Dinosaur.
The 3 horn, or Triceratops
gives him a ride safely away from the harmful dog eating
dinosaurs! Thanks 3 horn!
Bob thanks the Triceratops and goes to the T. rex exhibit.
