Dinosaur

https://www.nps.gov/dino/index.htm https://en.wikipedia.org/wiki/Dinosaur_National_Monument Dinosaur National Monument is located on the southeast flank of the Uinta Mountains on the border between Colorado and Utah at the confluence of the Green and Yampa Rivers. Dinosaurs once roamed here. Their fantastic remains are still visibly embedded in the rocks. Today, the mountains, desert, and untamed rivers flowing in deep canyons support an array of life. Petroglyphs hint at earlier cultures. Later, homesteaders and outlaws found refuge here. Whether your passion is science, adventure, history or scenery, Dinosaur offers much to explore. Dinosaur National Monument is located on the Colorado and Utah border with a parts of the monument in both states. Dinosaur fossils are not visible in the Colorado portion of the monument - only on the Utah side. The Quarry Visitor Center and Exhibit Hall (where you see the dinosaur fossils) are located approximately 7 miles north of Jensen, Utah. Canyon Visitor Center - Colorado Located near Dinosaur, Colorado, at the base of the Harpers Corner Road, the Canyon Visitor Center is the gateway to the monument's mountains and river canyons. This building is open in summer and closed during the winter. Exhibits and a park film orient visitors to resources, and staff are available to answer questions. A bookstore sells items that can further enhance your experience. Restrooms and water are available seasonally. There are no dinosaur fossil sites on this side of the park. Located on US Hwy 40, two miles east of Dinosaur, CO. Quarry Exhibit Hall - Utah The Quarry Exhibit Hall is where you can see a wall of approximately 1,500 dinosaur bones. This includes the remains of numerous species, such as Allosaurus, Apatosaurus, Camarasaurus, Diplodocus, and Stegosaurus. Exhibits, including an 80 foot (24 m) long mural, reveal the story of the many animals that lived in the Morrison environment during the Late Jurassic. This building is open year-round, except on certain holidays. Open hours change seasonally. Quarry Visitor Center - Utah Located 7 miles (11 km) north of Jensen, Utah, off Highway 149, the Quarry Visitor Center is the gateway to the Quarry Exhibit Hall and the wall of dinosaur bones. This facility features a staffed information desk, gift shop, and theater with a 12-minute park film. Exhibits introduce a variety of resources and places to explore within the monument.

Predicting Vegetation and Topographic Change in Response to Altered River Flows on the Northern Colorado Plateau Lots of things can impact the quality of your raft trip. Weather. Water levels. Packing the right (or wrong) gear. But would you expect plants to play a role? Riparian plants influence the shape and character of rivers—and river flow helps determine what grows where. This model can help river managers predict the downstream effects of shifts in flow, and respond accordingly. The model was tested in Dinosaur National Monument. A person stands near four rafts pulled up onshore near a river camp. Traits, Tradeoffs, and Pivot Points: How Climate, Plant, and Soil Properties Affect Vegetation Growth on the Northern Colorado Plateau As the northern Colorado Plateau heads into a hotter, drier future, there will be ecological winners and losers.

Robyn Henderek Series: Geologic Time Periods in the Mesozoic Era The Mesozoic Era (251.9 to 66 million years ago) was the "Age of Reptiles." During the Mesozoic, Pangaea began separating into the modern continents, and the modern Rocky Mountains rose. Dinosaurs, crocodiles, and pterosaurs ruled the land and air. As climate changed and rapid plate tectonics resulted in shallow ocean basins, sea levels rose world-wide and seas expanded across the center of North America. fossil dinosaur skull in rock face Series: Geologic Time Periods in the Paleozoic Era During the Paleozoic Era (541 to 252 million years ago), fish diversified and marine organisms were very abundant. In North America, the Paleozoic is characterized by multiple advances and retreats of shallow seas and repeated continental collisions that formed the Appalachian Mountains.

Updated Species Database Will Help Boost Amphibian Conservation Across the National Park Service To steward amphibians effectively, managers need basic information about which species live in parks. But species lists need constant maintenance to remain accurate. Due to recent efforts, the National Park Service now has an up-to-date amphibian species checklist for almost 300 parks. This information can serve as the basis for innumerable conservation efforts across the nation.

National Park Service U.S. Department of the Interior Dinosaur National Monument Fossil Discovery Trail The Fossil Discovery Trail winds through numerous titled rock layers Travel through millions of years of history on the Fossil Discovery Trail. Long ago, dynamic forces pushed and tilted these layers of rock upward. Later, erosion exposed the layers as colorful ridges. Erosion also revealed remnants of ancient ecosystems including now-extinct animals that inhabited landscapes quite different from what we see today. Discover more about several of these ancient ecosystems. Getting Started Trail Trivia Length: 1.5 mi/2 km one-way Elevation change: 150 ft/46 m Time to hike: about 1 hour Rock layers exposed: Stump Formation Morrison Formation Cedar Mountain Formation Dakota Sandstone Mowry Shale Frontier Sandstone Mancos Shale Geologic time exposed: Jurassic to Cretaceous This guide describes the trail as hiked downhill from the Quarry Exhibit Hall to the visitor center. Follow the guardrail down the right side of the road from the exhibit hall parking lot to find the trailhead. (You may also hike uphill from the trailhead located behind the visitor center.) Restrooms and drinking fountains are available during business hours near both trailheads. Restricted Access Road SHUTTLES ONLY (in Summer) RANGER-GUIDED (Fall - Spring) Prepare for this rocky, sun-exposed trail by wearing good hiking shoes and dress for the weather. In summer, that means bringing plenty of water, sunscreen, and a sun hat. The trail is very slippery when wet. Please stay on the established trail and leave all plants, rocks and fossils in place for the next hikers to discover.

The trail travels through the edge of an arch, or anticline, where layers are tilted steeply to the south. On the other side of Split Mountain, the same layers tilt to the north. As you begin your hike, take a moment to look at the rock layers that are dramatically uplifted and tilted around you. These were once horizontal layers of sediment that eventually turned into flat-lying sedimentary rock. So how did they end up tilted? 80 million years ago 60 million years ago About 60 million years ago, rocks here were pushed up like an arch. Since then, erosion exposed stronger sandstone and limestone as ridges while shale formed softer mounds. Thanks to the tilt, more rock layers are exposed in a shorter, less steep hike. 30 million years ago 3 million years ago Morrison Formation How Old? One of the more accurate ways to determine the age of a geologic layer is to examine the ratio of potassium to argon gasses trapped in crystals of volcanic ash. Unstable potassium turns into argon at a stable rate. By looking at crystals in ash that contain both potassium and argon, the ratio of the two elements gives geologists an estimate of the age of a rock layer. Each step leads you through rock layers with different colors, textures, and fossils. Sometimes these differences are subtle, sometimes striking. Most of the Morrison Formation is mudstone and clay, but watch for the trail spur that hugs a sandstone cliff. This part of the Morrison Formation is made up of river-deposited sand and gravel. Based on potassium-argon dating of volcanic ash, in older and younger layers on either side of the sandstone wall, this layer is estimated to be about 149 million years old. Fossil fragments of dinosaurs are embedded in the cliff along with impressions of freshwater clams. The Morrison Formation trail spur follows the same sandstone layer that is exposed in the Quarry Exhibit Hall. However, this cliff has not been worked on by paleontologists to make the bones easier to see. The first fossils along the spur are fragments that are somewhat shiny and dark orange in color. Some have a spongy-looking interior which contained bone marrow. Their texture is generally smooth and their size ranges from ½ inch to 10 inches in diameter. Find the fossil vertebrae about 10 feet above the trail. As you hike along the cliff, the quality and size of the fossil bones increase. Just past the mid-point of the spur, the trail dips a few feet. After the dip, look up on the cliff face to see eight vertebrae. Keep hiking and look around waist level for the end of a humerus. Saving the best for last, a large femur rests at the end of the spur. Sharp eyes can find more bones, depending on the angle o

Dinosaur National Park Service U.S. Department of the Interior Dinosaur National Monument Petroglyphs and Pictographs Petroglyphs at Cub Creek About 1,000 years ago, the Fremont people lived in this area and left evidence of their presence in the form of petroglyphs and pictographs. Several areas in the monument allow visitors to easily access these designs and ponder the mystery of why they were created. The Fremont Culture Archaeologists first studied and named the Fremont culture along the Fremont River in south-central Utah and have since traced it through much of the Green and Colorado River drainages. The lifestyle of the Fremont people varied considerably throughout that area, reflecting the diverse environments that they inhabited. In general, they lived in small bands or family groups, grew crops to supplement native foods, and did not build large permanent dwellings. In the Dinosaur National Monument area, archaeological evidence of the Fremont dates from about 200 A.D. to about 1300 A.D. While few actual houses remain, known dwelling places ranged from natural shelters (such as rock overhangs or shallow caves) to small “villages” in open areas. Archeological evidence suggests many dwelling sites were occupied only seasonally, as the people moved into and out of an area according to the availability of water and food. The Fremont relied heavily on native plant foods, such as piñon nuts, berries, and cactus fruits, and on wild game, including mule deer, bighorn sheep, smaller mammals, and birds. However, they also grew corn, beans, and squash, sometimes using irrigation techniques. This horticulture gave them, at least seasonally, a more settled life than a purely Pictographs at Deluge Shelter hunting-and-gathering existence, which in turn may have given them the time needed to create elaborate rock designs. The fate of the Fremont culture is unclear. Recent theories suggest that the Fremont’s lifestyle may have changed resulting from drought or other climatic factors, dwindling natural resources, or the influence of other neighboring cultures. Whatever the case, it is difficult to trace the Fremont as a distinct culture in the archaeological record after about 1200 A.D., but the Fremont petroglyphs and pictographs survive as a vivid reminder of these ancient people. Petroglyphs at Cub Creek Designs in the Rock Fremont designs include both petroglyphs (patterns chipped or carved into the rock) and pictographs (patterns painted on the rock). Pictographs are relatively rare here, perhaps because they are more easily weathered. Some petroglyphs show traces of pigment, possibly indicating that many designs originally included both carved and painted areas. Many sandstone cliffs darkened with desert varnish, a naturally formed stain of iron and manganese oxides, provided an ideal canvas for carving petroglyphs. Most of these designs are outlines, but some are completely pecked to form solid figures, and a few consist of small holes in closely-spaced rows. The style and content of Fremont designs vary throughout the region. The “Classic Vernal Style” predominates in Dinosaur National Monument. This style is characterized by human-like figures, animal- Many designs in the monument are fairly easy to access and allow up-close viewing. These designs are very fragile. Touching the petroglyphs and pictographs can damage the designs by leaving oils UTAH 191 44 COLORADO Viewing Designs 5 4 Why did the Fremont create these designs and what did they mean? Perhaps the designs served some ceremonial or religious purpose, related to hunting activities, identified clans, or simply expressed the artist’s imagination – or perhaps all or none of these. Attempts to interpret the designs by comparing them with recent Native American groups may provide clues, but the true meaning remains a mystery. behind that abrade the rock.

Human figures typically have trapezoidal bodies, which may or may not include arms, legs, fingers, and toes. Elaborate decorations on the bodies suggest headdresses, earrings, necklaces, shields, or other objects.

Dinosaur National Park Service U.S. Department of the Interior Dinosaur National Monument Josie Bassett Morris Wild and dangerous, romantic and adventurous, the American West is for most people today an almost mythological world, one separated from ours by time, technology, and civilization. Yet, for Josie Bassett Morris, the Wild West was a stark reality. Josie lived most of her 90 years of life in this austere, yet beautiful, landscape in a time simpler than today, when people depended directly on the bounty of the land for survival and “neighbors” for companionship. Embracing the Freedom of the Frontier In 1862, the United States Congress passed the Homestead Act in an effort to move people into their newly acquired territory of the American West. Born in Arkansas around 1874 to educated and wealthy parents, Josie was only three years old when she and her mother–ambitious, independent, strong-willed Elizabeth–and her mild-mannered father, Herb, packed their belongings and made the journey west by wagon. They homesteaded in an area called Brown’s Park, only 40 miles from the Cub Creek site that Josie homesteaded independently later in life. A Progressive Style of Womanhood The women of Josie’s family were not only pioneers of the west, but also represented a progressive style of womanhood. Josie married five times and she divorced four husbands, in a time when divorce was almost unheard of. For this, Josie, with her strong will, charm, and independence, garnered rumors about her throughout most of her life. Josie was universally admired, however. Living such a remote and rugged lifestyle, women were respected if they could work alongside the cowhands and run an efficient ranch, in addition to being feminine. With no money to buy property, Josie decided in 1913 to homestead again – this time in Cub Creek. Here she built her own cabin and lived for over 50 years. She shared her home with her son Crawford and his wife for a time; grandchildren spent summers working and playing alongside Josie. Written by Alida Bus, 2007 As a child in Brown’s Park, Josie contributed her part of the household and ranch chores. Once these duties were complete, young Josie was free to play in the surrounding wilderness with her four siblings. The children grew up having an intimacy with and dependence on the natural environment, forming values based on hard work and resourcefulness. Josie’s family hosted many guests in their home, including some outlaws like Butch Cassidy, which fostered in Josie a strong sense of hospitality, generosity and community. The Pioneer West in the Modern Age Raised on the frontier, Josie lived into the modern era of electronics. For friends and acquaintances in the 1950s, Josie was a link to a world past. During Prohibition in the 1920s and into the 1930s, Josie brewed apricot brandy and chokecherry wine. After a lifetime of dressing in skirts, she switched to wearing pants in her later years. She was tried and acquitted twice for cattle rustling when she was in her 60s. At the age of 71, in an ambitious move to revive a profitable cattle business, she deeded her land away and lost all but the five acres where her cabin still stands. In December of 1963 the legendary Josie suffered a broken hip while in her cabin; she died of complications in May of 1964. Josie’s Homesite Today Today Josie’s cabin would be considered a modest structure. It is hard to imagine this place as a hub of activity, a site where one individual poured heart and soul into endless hours of chopping wood, cooking meals, milking cows, entertaining guests, and tending the chicken coop and vegetable garden. Look closer at the walls and envision a bed where Josie slept through bitter cold nights. Breathe in and imagine the rich aroma of Josie’s homebrewed coffee and homemade biscuits. Envision how it would have been to be a guest at the generous hostess’ table. Take a moment to sit in the shade of the trees surrounding Josie’s cabin – trees she carefully planted to provide the shade and fruit necessary for survival in a harsh environment. Walk the short trail to the box canyon where Josie penned her livestock; the wooden fence still stands. Imagine living in this place without plumbing, electricity, or neighbors for over fifty years. Relax and let the stillness enchant you; it is this same peacefulness that Josie may also have felt here.

Dinosaur National Monument National Park Service US Department of the Interior Boating in the Monument 2017 Information and Regulations Warm Springs Camp Photo by Jacob W Frank Whitewater rafting is a popular way to experience the remote canyons in Dinosaur National Monument, but the Green and Yampa rivers should never be mistaken for placid rivers. When John Wesley Powell floated the river in 1869, the scenery enthralled his group, but the rapids caused them great anguish as boats overturned, men were hurt, and supplies were lost. Even today, many boats end up pinned on rocks, their boatmen bruised and battered. For that reason, permit holders and trip leaders must have previous experience on comparable rivers. Depending on the water level, some rapids are rated as high as Class 4. Boating permits are limited to protect the natural and cultural resources and to leave the river canyons unimpaired for future boaters. The following rules and regulations have been put in place to assure that all travelers on the river will have a safe, peaceful, and memorable trip. The permit holder must know the rules and regulations described in this booklet, and assure that all persons participating in your boating trip are aware of them.

U.S. Fish & Wildlife Service National Park Service U.S. Department of the Interior Guide to Important Fish Species in Dinosaur National Monument This pamphlet is a joint project by the National Park Service and the U.S. Fish and Wildlife Service, both agencies of the Department of the Interior. For questions please contact: Tildon Jones U.S. Fish and Wildlife Service Vernal, Utah tildon_jones@fws.gov or Tamara Naumann Dinosaur National Monument tamara_naumann@nps.gov Reports of captured burbot can be given to any Dinosaur National Monument ranger. (Please include information on the specific location.) June 2014 ON THE COVER Sam Sewell holding a Colorado pikeminnow caught in the Green River, ca. 1928 Dinosaur National Monument Archives Why are these fish “important?” Native species Introduced species Most of the native fish species described in this guide are unique to the Colorado River Basin, which includes the Green and Yampa rivers in Dinosaur National Monument. Others may occur in additional river systems, but represent important contributors to the river ecosystems in Dinosaur National Monument. There are more introduced fish species in Dinosaur National Monument’s rivers than described in this guide, but those included are of particular concern for their contribution to the decline of native fish populations in the Colorado River Basin. The natives found only in the Colorado River Basin have evolved specialized traits to survive in the difficult natural environments found in these rivers, which include highly variable seasonal flows and heavy sediment loads. With the dramatic changes that dams and water diversions have made in the hydrology of these rivers during the 20th century, most of these species are now severely reduced in range and population numbers. Some, such as the bonytail, are very close to extinction. All of these native fish represent a unique and irreplaceable natural heritage. Fishermen can aid in the recovery of native fish species by IMMEDIATELY RELEASING unharmed any native fish caught in Dinosaur National Monument. Most of these introduced species are voracious predators on native species. The catfish can have a different impact on the Colorado pikeminnow (itself a predator) because of its spiny fins. There have been many reports of pikeminnow found choked to death, with catfish wedged in their throats. The introduction of these nonnative species to the basin’s river environments has occasionally been by accident, but more frequently has been deliberate—often through misguided attempts to “improve” the fish populations in these rivers. Although nonnative fish cannot be legally stocked in Dinosaur National Monument, many have arrived here from up- or downstream. Please DO NOT RELEASE any of the introduced species discussed in this guide back into the rivers, unless specifically required to do so by state regulations. Fishermen are reminded that all fishing within Dinosaur National Monument is subject to state fishing regulations, including the possession of a current fishing license from the appropriate state. Bonytail Utah Division of Wildlife Resources Native • Federally listed as Endangered • Relatively small eye and mouth for its overall size • May have a small hump behind its head, or more often the head appears compressed • Very thin tail fin attachment for the overall body size • Please RELEASE UNHARMED immediately The bonytail has experienced the most abrupt decline of all the large native fish species of the Colorado River Basin. After the construction of Hoover Dam on the lower Colorado River, the bonytail quickly disappeared from the lower Colorado River Basin. Today the bonytail is extremely rare in the upper Colorado River Basin, and reproduction in wild populations is generally unsuccessful. Present populations are being maintained by restoration stocking programs. Colorado Pikeminnow M.T. Jones, USFWS Native • Federally listed as Endangered • Most that are caught in Dinosaur National Monument are large (12–36 inches in length) • Cylinder-shaped, silvery white body with gold flecks • Large, fleshy lips with a split above the upper lip • A compressed, somewhat flattened head with no teeth • Single dorsal (top) fin is behind the midpoint of the body length • Please RELEASE UNHARMED immediately The Colorado pikeminnow is the largest minnow in North America. In the early 1900s it was known as a big, aggressive, and easily caught “sport” fish. In those times the Colorado pikeminnow was the top fish predator in the upper Colorado River Basin. Historical accounts include descriptions of pikeminnows up to six feet long and weighing 80 pounds. Many earlier settlers also considered pikeminnows to be an abundant and valuable food source. Other common names for the species have included “whitefish,” “white salmon,” and “squawfish.” The Colorado pikeminnow is known for its long-distance spawning migrations of up to 200 miles. Today the
