FOSSIL QUEST
To Josh and Pedro, it sounded like a great summer trip: fossil hunting. They would be outside, and the trip would look awesome on college applications. But where should they go? And who would lead them? Their parents were okay with the idea—if they stayed within the United States. Both boys liked dinosaurs and extinct mammals, but for this trip, Josh wanted to search for the very first animals. Pedro, on the other hand, loved his pet parakeet so he wanted to look for the ancestors of birds. But where could they find these fossils… and were any good sites close enough to satisfy their parents?
They realized that they needed to figure out in which periods their target animals lived. Then, they needed to figure out where they could find rocks of the appropriate ages. As you read this chapter, look for clues to the geologic time periods Josh and Pedro's target animals might have lived in and where the two boys might expect to find their fossils. Then, solve the mystery.
Never Stop Exploring Your World.
Discovering where Josh and Pedro's “Fossil Quest” will take them is only the beginning. Take a video field trip with the ecogeeks of Untamed Science to see where the mystery leads.
