Morrison, CO: Ancient Landscapes, Ancient Lives
Morrison, Colorado is known for its exceptional place in paleontological history. Not only is the Jurassic-famous Morrison Formation named after the Town of Morrison, but it also preserves some of the first large Jurassic dinosaur fossils to be collected and described by science. Jeffco residents can explore the tomb of the first Stegosaurus, touch the mind-blowingly massive forelimb of an Apatosaurus, and experience new discoveries—such as evidence of a hatchling Stegosaurus—right in their backyard, making them the envy of paleonerds around the globe. This presentation will provide a glimpse into the ancient worlds and ancient lives our local landscape reveals, if you are curious enough to wonder about it.
