Ralph B. Clark Regional Park includes a beautiful interpretive center with an extensive fossil collection. It displays marine fossils dating from about one million years ago, to more recent terrestrial mammals that walked the earth tens of thousands of years ago. These specimens were recovered inside the boundaries of Clark Park, and from the development of the Coyote Hills area in northern Orange County.
