The document discusses geological timescales and how fossils found in Grand Canyon National Park and Capitol Reef National Park in Utah provide evidence about periods of the Phanerozoic Eon. Specifically, it notes that during the Phanerozoic Eon the number of species with shells and skeletons dramatically increased, as did the total number of individual organisms, species, and average size of organisms preserved as fossils. The document also mentions a virtual field trip to these two national parks to see fossils from different periods in geological history.
