Both, that notes, are maritime animals. But take a quick look at a map the landlocked Newport and a question can quickly involved mind: Why is vital taking his students here to look because that the fossilized continues to be of maritime animals, come a website that is more than 190 miles from the Atlantic Ocean?"When Africa collided through North America, throughout the top Devonian period, every these rocks were folded up into the Appalachian Mountains and also ended up here—about 375 million year ago," an essential explains.

If we were going to carry out an evolutionary study, exactly how would we attack this outcrop differently?"And the impromptu lesson, at the height of this vertigo-inducing cliff, turns right into a question-and-answer practice on the scientific process and a great in just how to deal with paleontological mysteries.
