SUMMARY:Como Bluff Three\, Nail Quarry 2025
DESCRIPTION:Home of the famous “Bone Wars” in the 1880s\, South-Central Wyoming’s Como Bluff has produced many well-preserved specimens from the Morrison Formation. Most of these were collected by men working for O.C. Marsh between 1877 and 1889 as well as the Hubbel brothers under E.D. Cope between 1879 and 1880. \nThe Nail Quarry is on private ranchland and Anita Colin along with J.P. Cavigelli are the quarry managers. Hundreds of bones have been excavated from this site; primarily remains of “classic” Jurassic dinosaurs such as Allosaurus\, Apatosaurus\, and Stegosaurus. All fossils are for scientific research and go to the Tate Museum in Casper\, Wyoming\, where they are prepped and studied by J.P. Cavigelli and his team. \nThis field opportunity is ideal for those with little or no experience working in a dinosaur quarry. Some tools are provided; however\, people are encouraged to bring their own tools. There are jobs for everyone from learning to identify and excavate fossils to hauling matrix out of the dig site. \nAbout 1/2 mile from the quarry is a marine exposure called the Sundance Formation where participants can collect and keep fossils such as belemnites\, ammonites and other invertebrates of the ancient seas. \nDirections will be provided\, and high-clearance vehicles are recommended\, for driving into the quarry. Folks who do not have a high-clearance vehicle can arrange to carpool with other participants or can park (and camp) at the top of the hill and walk the rest of the way into camp. People can camp at the quarry or stay in motels in Rock River or Medicine Bow for around $100 per night. \nWIPS registration is $10 per person\, and the additional cost of the trip is $50 per person\, per weekend. Checks need to be made out to the Tate Geological Museum for this additional cost.

SUMMARY:September Program - Karen Chin -A Dung’s Eye View of Dinosaur Life in the Cretaceous Period
DESCRIPTION:Brief description of presentation: \nStudies of 75-million-year-old coprolites (fossil feces) from Montana and Utah reveal that some plant-eating dinosaurs periodically consumed foods we would not expect giant herbivores to eat.  This talk will describe the fossil evidence for this unexpected discovery and how it changes our understanding of dinosaur paleobiology.   \nBrief bio:\nKaren Chin is a professor in the Department of Geological Sciences and Curator of Paleontology at the Museum of Natural History at the University of Colorado Boulder.  She began her career in paleontology working with dinosaur paleontologist Jack Horner at the Museum of the Rockies at Montana State University.  She later received her doctorate from the University of California at Santa Barbara where she studied with paleobotanist Bruce Tiffney.  Dr. Chin studies Mesozoic ecosystems — mostly through analysis of fossil feces (coprolites) and burrows.  She is particularly interested in ancient symbiotic relationships\, trophic interactions\, nutrient cycling processes\, evidence for paleoenvironmental conditions\, and the taphonomic processes that constrain our understanding of ancient ecosystems.

SUMMARY:Flat Tops
DESCRIPTION:The destination for this trip is the fossiliferous Dyer Formation on the White River Plateau of Colorado\, located in the White River National Forrest north of Glenwood Springs and south of the Flattops Wilderness Area. The Dyer formation is upper Devonian\, approximately 370 M.A. deposited when western Colorado was a shallow\, near shore ocean environment. Colorado at that time was positioned approximately 20 degrees south of the Equator.  The Plateau was uplifted during the Laramide Orogeny in the Cenozoic. \nMarine invertebrate fossils to be collected include brachiopods\, bryozoans\, crinoids\, sea stars\, gastropods\, cephalopods and rugose and tabulate corals.  All specimens can be accessed on the surface or with small hand tools.  No power tools or mechanical excavation is allowed. \nTrip Logistics: \nWe will meet on Monday\, September 15 at 12:00 pm in a parking lot at the base of Coffee Pot Road.  Special Note: Coffee Pot Road is impassable when wet. If we encounter rain we cannot continue\, and alternate plans will be communicated. Elevation: 6\,168–10\,644ft

SUMMARY:Indian Springs Trace Fossil NNL Site
DESCRIPTION:This 450 million-year-old National Natural Landmark changed paleontology history when it was discovered on a private working ranch by Bennie Thorson just east of Cañon City in the 1960s. Carly Thorson\, his daughter\, provides a guided tour and will decipher and explain the movement of the creatures whose incredibly-preserved fossil footprints were captured in one moment of time when a storm event covered the shallow floor of this Ordovician – Harding Sandstone Formation estuary. Literally stopped in their tracks\, we will learn to spot a resting spot\, feeding trace\, flick of a fin in the sand\, even the impression of bristles on a leg\, a stinger on a tail\, and the tiniest trilobite tracks. \nIndian Springs is considered the best Ordovician trace fossil site in North America and has been a federally protected registered National Natural Landmark since 1979. It is a significant location for paleontology\, geology\, archeology\, botany\, and recent history. It is the type locality for 9 trace fossil genera and species\, and illustrates traces of arthropods (trilobites\, eurypterids\, horseshoe crabs)\, polycheate worms\, and ostracoderm fish – primarily Astraspis desiderata\, a primitive jawless fish which represents the earliest record of cartilage-to-bone in the chain of evolution. \nDuring the walk through pristine juniper woods and then along a 2-track\, Carly will describe the medicinal nature of various plants\, a Civil War site\, a petroglyph\, and geologic features. \nIndian Springs is a private working ranch. No collecting is allowed. Participants must walk in as a group and leave as a group – no early departures except in an emergency. The 1/2 mile walk to the monument is not strenuous\, but there can be cactus\, rattlesnakes\, cows\, barbed wire\, etc. Wear sunscreen\, bring water and snacks/lunch\, and wear hiking boots; no open toed shoes allowed. The tour will depart at 9:30 am sharp. Please arrive by 9:15 am. For safety reasons\, late arrivals will not be allowed to go on the field trip. The field trip will last 2-3 hours. \nAn additional $15 per person for the guided tour will be collected at the site on the day of the field trip. Be certain to bring the exact cash of $15 per person\, as checks and credit cards can’t be accepted. Additional information will be sent out a week prior to the field trip.
