How can we protect known fossil sites so that they can continue to help science? Objective Students will study an outcrop that has been excavated along with 2 petrified stumps and make their best judgements on the amount of erosion that has occurred, what is being done to prevent erosion, how many fossils they see, how many fossils they think have been damaged/stolen/lost, how accessible the site it, and what is being done to protect the sites. They will be evaluating the sites based on a number system. Background Paleontologists visit different sites around the National Monument and monitor a Duration: 60 Minutes.
