Roll out a piece of paper of the proper length, and measure and label the eras.
We have some fossils that are quite good including dinosaur poop, petrified wood, some nautiloid cephalopod isorthoceras from Graf, Iowa, and some Devonian age coral that is 400 million years old from the Devonian Gorge in Iowa City, IA, all courtesy of our fossil gathering friends in the Physics Department and the Science Ed. Department.
