| Note brown and white CJ7 jeep parked along the dirt trail through Coral Reef Canyon, at bottom right. The bold exposures belong to the geologically oldest subunit "member one" of the Upper Triassic Luning Formation, which here yields prolific quantities of tangled reef-forming corals and sponges, in addition to weathered-free brachiopods, pelecypods, gastropods, echinoids (sea urchins), belemnites (straight-shelled cephalopods related to squids), ammonites (the Triassic types are also called ammonoids), and not a few ichthyosaur skeletal elements (be sure to take photographs, only, of the bones, unless you've secured a special use permit from the United States Bureau of Land Management). |
