OVERVIEW: Agate Fossil Beds National Monument
Agate Fossil Beds National Monument, located in northwest Nebraska, is part of the National Park Service, within the Department of the Interior. The over three-thousand-acre park is situated about forty-three miles north of Scottsbluff and twenty-two miles south of Harrison in the sparsely populated ranchland along the Niobrara River. The national monument was authorized on June 5, 1965, but was not established until June 14, 1997. Each year, thousands of visitors come to enjoy the unique experiences available at Agate Fossil Beds National Monument. We invite you to explore the park's natural beauty, from its elevated rock tablelands to its sweeping Niobrara Valley and meandering Niobrara River, which creates eleven miles of riverbank through the four-mile length of Agate Fossil Beds National Monument. The current wildlife at the park includes but is not limited to: Swanson's Hawk, Golden Eagles, Western Meadowlarks, Bard Owls, Sandhill Crane, Canada Geese, Prairie Rattlesnakes, Bull Snakes, Porcupine, Horned Toads, Cottontail Rabbits, Snapping Turtle, Toads, and Wild Turkey. Discover the Miocene bonebeds and learn about the abundance of mammals and vegetation that once lived here twenty-three million years ago. Hike the one-mile Daemonelix Trail to explore the exhibits of the spiral corkscrew fossil of the Paleocastor, an ancient land beaver, or the two-point-seven-mile Fossil Hills Trail to see historic dig sites and take in the park's picturesque landscape.
Learn about and honor the area's Native American heritage at the James H. Cook Collection of artifacts in the Visitor Center. This is a collection of gifts from Chief Red Cloud from Lakota Sioux and others from Cheyenne and other Plains Indians.
For those seeking to learn more about the park during their visit, fossil displays, informative audio guides, paper trail maps, Braille brochures, and large print information about the exhibits can be found at the Visitor Center. To find out more about what resources might be available or to contact the park directly, visit the "Accessibility" and "More Information" sections of this audio-described brochure.
OVERVIEW: Accessibility
We strive to make our facilities, services, and programs accessible to all.
Parking Spaces: There are three designated reserved parking spaces in the main lot at the visitor center and one designated reserved parking space in the Daemonelix Trailhead lot.
Park Theater: Park movie is located in a separate room just after making a left U-turn from the entrance doors. Seating is made of movable chairs on a flat, carpeted surface. The movie is not yet audio described. However, park rangers trained in audio description are happy to assist. Assistive Listening Devices are available at the front desk.
Visitor Center: Braille brochures and large print information about the exhibits are available at the front desk. Benches without arm rests or backs are available throughout the one-story building. The museum has a foyer with indoor restrooms. Two outward-facing double doors lead to a tile hallway which leads to a large, carpeted room with free-standing and wall-mounted, enclosed fossil exhibits to the left with wide aisles and approaches. The front desk is straight ahead containing a wheelchair accessible counter between the two higher counters. A small bookstore is to the right within the same room. Immediately to the right of the carpeted room from the entrance is an inward-opened, glass door. This leads to a small room of wall-mounted exhibits and a touch table. Straight across the room from the glass door are heavy wooden double doors that open outward. This leads to a darker carpeted room with ambient lighting and music. The room moves in a crescent shape to the left with displays behind plexiglass on the right, left, and one in the center. Another set of heavy wooden double doors open outward to the aforementioned bookstore.
Hiking Trails: There are two hiking trails in the park. For orientation to the hiking trails, we invite you to watch a brief, interactive film with a paleontologist narrator who walks the trails with a camera. The Fossil Hills Trail is a 2.7-mile round trip, gradually sloping, 5-foot wide, cement trail. There are three covered benches along the trail. The cement trail connects to a sheltered picnic area with wheelchair accessible tables, the visitor center, and the main parking lot. The Deamonelix Trail is a 1.0-mile round trip, 4-foot wide, gravel trail. It is mostly flat with one steep section that climbs up and around a hill with some steps. The trail contains two fossil displays behind plexiglass covers.
Service Animals are welcomed in all park buildings. All dogs on leash are welcome on park trails. Dog owners are responsible for picking up after their dogs. A relief area is located to the north of the visitor center parking lot.
NPS App: The NPS app contains additional tours and information about the park accessible by screenreading software.
OVERVIEW: Front Side of Brochure
The front side of the brochure begins with the distinctive National Park Service (NPS) black bar at the top containing the text "Agate Fossil Beds" in large font on the left side, and two separate two lined texts in smaller font are on the right, reading "Agate Fossil Beds National Monument" with "Nebraska" underneath, and to the right of it reads, "National Park Service" with "U.S. Department of the Interior" underneath. A National Park Service Arrowhead logo is situated to the far right of the band. Below the band is a picture of a large diorama, containing 7 skeleton models, belonging to extinct animals found here. The text below describes the story and history of the animal bones found fossilized here. The middle section contains four horizontal panels of historic photographs and drawings, which are described in text on the right. Text below are about "What animals roamed here", and "Discovery of the fossils" by Rancher James Cook. The lower portion of the brochure is separated by a thin black strip split in the middle. The left side of the black strip reads "Exploring Agate Fossil Beds". The text identifies visitor center museum, services and safety information. A map of the rectangular shaped 4-mile long park is in the middle, surrounded by visitor information. The right side of the black strip reads "The Cook Collection of American Indian Artifacts". Two columns of text identify many items found in the collection, followed to the right by a photograph of a Native American shirt. Text continues on the right of the picture. A thin black band runs the length of the brochure's bottom.
IMAGE and TEXT: Agate Fossil Beds
DESCRIBING: Horizontal color photograph with iconic NPS black bar across the top with the title Agate Fossil Beds on the left and the NPS arrowhead logo on the right. Additional small font text in the black bar is Agate Fossil Beds National Monument, Nebraska, National Park Service, U.S Department of the Interior. Four columns of text appear under the photo.
SYNOPSIS: Eight life-size skeletal models of extinct animals, seven of which are visible, huddle around a pile of scattered bones and a diminishing puddle of water within an indoor display. A floor to ceiling mural on the right and left shows a sandy, dry environment, suggesting drought conditions. Three vertical floor to ceiling windows provide an outdoor view into the real park landscape of grays, faded greens and white leading to two small hills in the far distance, one peaked and one flat. The bones depicted in the diorama were discovered in those hills.
IN-DEPTH DESCRIPTION: The exhibit is made up of hard packed sand and a few tufts of brownish-green and dark red grasses throughout. Seven skeletal models cluster into three groups (described from left to right). On the left, a grouping of two models consists of a small knee-high, dog-like creature and a massive wild hog-like beast with a large skull. The dog has a long tail and neck and stands with its small head displaying its sharp teeth at the larger beast to its left. This much larger and wider hog, heaviest boned of all the animals, stares back with its large skull that takes up about a quarter of its body. Its front legs begin where the small dog’s tail starts. Behind the hog-like animal’s short neck, a massive, flat, bow-tie shaped bone extends upward from its spine. Continuing down the horizontal spine, eleven crescent moon-shaped ribs point toward the ground on both sides while straight, flat bones extend straight up. Past its hind legs, a small tail emerges straight out toward the mural on the left-hand side of the display. The second grouping of three models consists of another hog-like animal and two tall giraffe-like animals with medium-sized skulls. This large hog-like animal stands in front of the center vertical window. Its massive head hovers over a giraffe-like animal, which lies prostrate on its side with legs outstretched in the middle of the scene just beyond a circular pile of scattered bones. This animal also has crescent moon-shaped ribs that curve up and away from its horizontal spine. Its long neck and head twist back on the ground toward the bone pile. This animal appears to be deceased. To its right, the second giraffe-like animal stands tall, its neck extended straight up. Its head faces down toward the other animal. Its mouth is open and one front leg reaches forward. The final grouping consists of two more giraffe-like animals on the right side of the display. One, while standing tall, positions itself a few feet behind the other. Open mouthed, it gapes at the scene across the bonebed. The other giraffe-like animal bends its front legs and reaches its neck down toward a small puddle of water between it and the bonebed. Its large front feet lie flat against the ground while its hind feet stand on its toes which are three distinct bones. In the foreground, portions of three exhibit signs show blurry text and images.
CAPTION: Fossil exhibits in visitor center.
CREDIT: NPSRELATED TEXT: About 19–20 million years ago drought struck the western Nebraska plains. Deprived of food, hundreds of animals died around a few shallow water holes. Over time their skeletons were buried in the silt, fine sand, and volcanic ash carried by the wind and reworked by streams. An ancient water hole with hundreds of fossilized skeletons is preserved today in the Niobrara River valley at Agate Fossil Beds National Monument.The early 1900s discovery of this deposit and others nearby was important to the developing science of paleontology. Study of these fossils—continuing today—has helped answer questions about the past. But what were the conditions that created this drought and brought these animals together so long ago? Millions of years before the drought, in the Age of Dinosaurs, erosion from mountain ranges to the west formed the bed of a shallow sea. About the time dinosaurs went extinct, the Rocky Mountain ranges were forming, the sea receded, and tropical lowlands occupied what is now the Great Plains.North America’s climate became ever cooler and drier, and volcanic activity in the western United States produced enormous amounts of ash blown eastward. Ash-mantled plains were home to great herds of plant-eating mammals and their predators. As in today’s east African savannas, the rich volcanic soils supported grasses that, together with small trees and bushes along shallow streams, fed grass- and leaf-eaters. Many animals that thrived here depended on the moderate climate for their survival, and their numbers expanded to the capacity of the food available.In time the climate grew more arid. The Rocky Mountains kept rising and blocked the flow of moisture-laden air from the west. With less rain came plants that could survive with less water. Droughts were common. Streams dried up and grasses withered. Water-dependent animals congregated at water holes between times of feeding on the dwindling plants. Large animals like the rhinoceros and the chalicothere Moropus, a distant relative of the horse, finally could not travel far enough to find fresh forage, so they died in the shallow water of the few remaining ponds.Hundreds and thousands of some species died, littering the area in and around water holes with their remains. In time the rains returned, the streams filled, and the process of burial began. Silt, sand, and ash covered the remains, burying them under several feet of wind- and stream-transported sediment.

TEXT: What Animals Roamed Here?
While some animals whose fossil remains were found at Agate Fossil Beds are now extinct, others are represented by a few modern relatives or descendants.
Palaeocastor had powerful clawed forelimbs for digging and long, curved teeth like modern beavers. Herds of Stenomylus, gazelle-camels about two feet tall, grazed grasslands beside the three-toed, pony-sized rhinoceroses Menoceras. The most common mammal in the bonebed, Menoceras may have roamed these plains in large herds. Only a few oreodonts, about the size of a sheep, have been found here, and they are most common in the carnivore dens nearby, where they were the prey of beardogs.
Fossil remains of the ancestors of the modern horse, Parahippus, also have been found in the water hole but are rare. Horses became extinct in North America millions of years after the die-off event at Agate, not to return until brought back by the Spaniards. Moropus was quite fantastic. Related to both the horse and rhinoceros, it was large, had back legs shorter than the front, with great clawlike hooves. It probably browsed leaves of bushes and small trees.
Another large animal, Dinohyus, was a giant entelodont related more closely to cows and pigs than to carnivores. Tracks of this huge scavenger have been found in the water hole mud. It broke bones with its teeth (bite marks show on chalicothere limb bones). Discoveries in the 1980s included fossil remains of beardogs and other carnivores and their dens—one of the few paleontological sites of this type in the world.
TEXT: Discovery of the Fossils
Most of the land that is now Agate Fossil Beds National Monument was once part of the Agate Springs Ranch owned by James and Kate Cook. They bought the ranch from her parents in 1887, a few years after they had found “a beautifully petrified piece of the shaft of some creatures leg bone.”
Erwin H. Barbour of the University of Nebraska, in 1892, was the first scientist to examine the strange Devil’s Corkscrews at Agate, later recognized as the fossilized burrows of Palaeocastor. In August 1904, O.A. Peterson of the Carnegie Museum discovered the great bonebed with the help of Harold J. Cook, son of James and Kate. Scientists from Yale University, the American Museum of Natural History, and other institutions also worked here, mostly between 1904 and 1923. The competition to find the best bones sometimes grew spirited. The work of these bone hunters formed many outstanding collections in museums around the world.

IMAGE and TEXT: The Cook Collection of American Indian Artifacts
DESCRIBING: A small, color photograph.
SYNOPSIS: A long-sleeve, light-brown, antelope hide shirt with a crew neck and numerous long fringes along sleeves and sides. It is similar to a long-sleeve pullover sweater. The garment's design is intricate adorned with purple, green, and red colors.
IN-DEPTH DESCRIPTION: Front of shirt: Purple paint smudges the center of the leather shirt. A non-painted equilateral triangle interrupts the purple paint and points down, flush with the neckline in the center of the chest area. The triangle is outlined with short, inch-long, leather fringe. Two leather strings hang from its bottom. The triangle contains three smaller, purple equilateral triangles in a neat column, pointing the same direction. A 4-finger width strip of yellow falls over the shoulder to near the bottom of the shirt on both sides of the neck and stops the purple from continuing to the sides. Three, long, skinny, isosceles triangles paint the top and bottom of each strip as if claws were holding it down. Fringe leather strings hang passed the bottom of the shirt from the outer border of each yellow strip like a horse's mane. It conceals the outer seams of the shirt. Sleeves of shirt: Each long-sleeve has a 2-finger width separate leather strip sewn down the middle of the entire length. Purple, blue, and yellow horizontal stripes create a pattern around one red horizontal stripe at the center point of each leather strip. Three isosceles triangles like the ones on the yellow strips of the main shirt protrude out from each side of the stripes. Braided leather strings thickly hang passed the bottom of the sleeves from the outer border of each leather strip.

RELATED TEXT: James H. Cook was a frontiersman, hunter, and scout before he settled on the Niobrara River. Cook first met Chief Red Cloud in 1874 when Yale University Professor Othniel C. Marsh came to western Nebraska looking for fossils.The Oglala Lakota (Sioux) were suspicious of Marsh because most white men they knew were gold seekers. But “Captain” Cook helped convince Red Cloud and the other Oglala that Marsh was what he said he was, a bone hunter. Over the years Cook often helped the Oglala and Cheyenne. A steadfast friendship grew up between the Cook family and the Indians, who brought gifts and told them stories about individual items. The family’s collection now belongs to the park, and many items are displayed in the visitor center.Pictographs painted on hides—one of a buffalo hunt and one of Custer’s Last Stand—saddles, bows, shirts, moccasins, bags, war clubs, pipes, and guns make this collection an outstanding representation of Plains Indian culture. Cook’s interest in fossils led his son Harold to become a paleontologist, publishing many papers and taking part in important scientific research. Preserved and available to researchers here at the park are the Cook collection, other natural history specimens, the paleontological library of Harold Cook, and family correspondence, books, and papers that span four generations.

TEXT: Life in the Cenozoic Era—the Last 65 Million Years
From simple beginnings, great numbers and varieties of life forms have evolved and populated the Earth. For 140 million years before the Cenozoic Era, dinosaurs held dominion over the land. Mammals also existed, but they were small and not abundant. As the dinosaurs perished the mammals took center stage. Even as mammals increased in numbers and diversity, so did birds, reptiles, fish, insects, trees, grasses, and other life forms. The fossil record gives us a fascinating glimpse into the Cenozoic Era. Without fossils we would have little way of knowing that ancient animals and plants were different from today’s. With fossils we discover that an extraordinary procession of organisms lived in North America and around the world. Species changed as the epochs of the Cenozoic Era passed. Those that could tolerate the changes in the environment survived. Other species migrated or became extinct. The fossil record tells these stories, but the study of fossils remains, paleontology, also raises many questions: What types of environments did these plants and animals live in? How did they adapt to climatic changes? How did different groups of plants and animals interrelate? How have they changed through time? Fossils are studied in the context in which they were found and as one element in a community of organisms. Every fossil can serve as a key to unlock knowledge, so the National Park Service is especially concerned with the protection of these keys as the questions unfold. The Cenozoic Era continues today—see the right side of the chart below—and scientists estimate that as many as 30 million species of animals and plants now inhabit the Earth. This is a mere fraction of all life forms that have ever existed. Scientists now think that about 100 species will become extinct every day, a rate accelerated by human actions. Pollution of the air and water; destruction of forests, grasslands, and other ecosystems; and other adverse changes to Earth’s environment challenge life’s very ability to survive. “Looking back on the long panorama of Cenozoic life,” Finnish scientist Björn Kurten has said, “I think we ought to sense the richness and beauty of life that is possible on this Earth of ours.” It is no longer enough to plan for the next generation or two, Kurten suggests. We should plan “for the geological time that is ahead. . . . It may stretch as far into the future as time behind us extends into the past.”
IMAGES and TEXT: Paleocene
RELATED TEXT: Began 65 million years ago.
The Paleocene Epoch began after dinosaurs became extinct. Mammals that had lived in their shadows for millions of years eventually evolved into a vast number of different forms to fill these newly vacated environmental niches. Many forms of these early mammals would soon become extinct. Others would survive to evolve into other forms.
The variety of other animals and plants also increased, and species became more specialized. Although dinosaurs were gone, birds continued to flourish, and reptiles lived on as turtles, crocodiles, lizards, and snakes.

IMAGES and TEXT: Eocene
RELATED TEXT: Began 55 million years ago.
In the Eocene Epoch mammals emerged as the dominant land animals. They also took to the air and the sea. The increasing diversity of mammals begun in the Paleocene continued at a rapid pace in the Eocene. The many variations included some of the earliest giant mammals. Some were successful, some not. The fossil record reveals many mammals quite unlike anything seen today. Increasingly, however, there were forest plants, freshwater fish, and insects much like those seen today.

IMAGE 2 of 12: Gar
DESCRIBING: A small, color illustration
SYNOPSIS: The Gar is a long fish, about 2x the length of the herring, and 4x the length of the sunfish. Much of its length comes from its long nose, which stretches in a spindly, thin beak for about ⅓ of the fish’s body length. It has huge round eyes, and 5 fins. Three of these fins are on its underside, spaced evenly, with the first two being smaller and the back fin being large and spotted. There is a matching fin on top that is also large and spotted, and the tail fin is the largest of all, behind the fish. The gar’s scales are almost square, giving it a disco ball effect. The scales are lighter brown on top of the fish, dark brown in a middle stripe down the fish’s body, and white on the belly of the fish.
CAPTION: Many freshwater fish lived in North American lakes during the Eocene Epoch. Gars, herring, and sunfish are similar in appearance to those Eocene fish. Found at Fossil Butte NM.

IMAGE 12 of 12: Silhouette of small horse
DESCRIBING: A small, black illustration is the first and the smallest of the timeline of horses.
SYNOPSIS: A black silhouette of a small horse-like creature. Its shape and size resemble a cross between a cow and sheep.
CAPTION: Living in Eocene forests, the first horse-like animals were barely bigger than today’s domestic cat. Throughout the Cenozoic Era their size increased. Their legs became longer, and their feet changed from many-toed to single-hoofed for faster running. Their teeth evolved from being adapted for browsing to being adapted for grazing. Just a few of the species in the evolutionary history of horses are shown here in silhouette across this chart. Fossil horses occur at many sites in the National Park System.

IMAGES and TEXT: Oligocene
RELATED TEXT: Began 34 million years ago.
The Oligocene Epoch was a time of transition between the earlier and later Cenozoic Era. The once warm and moist climate became cooler and drier. Subtropical forests gave way to more temperate forests.
Late in the Oligocene, savannas—grasslands broken by scattered woodlands—appeared. These changes caused mammals, insects, and other animals to keep trending toward specialization. Some adapted to the diminishing forests by becoming grazers. Early types of mammals continued to die out as more modern groups—dogs, cats, horses, pigs, camels, and rodents—rose to new prominence.
IMAGE 1 of 3: Ekgmowechashala
DESCRIBING: A small, color photograph.
SYNOPSIS: Weighing about five pounds, this 4-legged, light brown, furry animal with a wide body and a small head hangs upside down from a thick tree branch. Its long furry tail tucks between its back legs as each of its five toes grasp the top of the branch. Its head comes to a point with its small nose and mouth. Its rounded ears lie flat behind its large circular eyes.
CAPTION: Ekgmowechashala marked the end of the original primate lineage in North America. A small lemurlike primate, it may have used large skin folds to glide from tree to tree. Its name means “little cat man” in Lakota, which the discoverer understood to be their name for monkey. Found at John Day Fossil Beds NM.

IMAGES and TEXT: Miocene
RELATED TEXT: Began 23 million years ago.
The abundance of mammals peaked in the Miocene Epoch. The refinement in life forms that marked this epoch saw many animals and plants develop features recognizable in some species today. The forests and savannas persisted in some parts of North America. Treeless plains expanded where cool, dry conditions prevailed. Many mammals adapted for prairie life by becoming grazers, runners, or burrowers. Large and small carnivores evolved to prey on these plains-dwellers. Great intercontinental migrations took place throughout the Miocene, with various animals entering or leaving North America.
IMAGE 1 of 7: Moropus
DESCRIBING: A small, color photograph.
SYNOPSIS: This large, brown, furry animal stands on four, thick, muscular legs. The feet have three distinct clawed toes. Its front legs are longer than its rear legs causing its spine to slope down to a short stubby tail. Its bulky body has a thick, extended neck and an oblong, almond-shaped head with small ears that point straight up. Its upper lip extends over the bottom lip of its mouth.
CAPTION: Moropus was a distant relative of the horse and one of the more puzzling mammals. For many years paleontologists thought its feet had claws rather than hooves. Found at Agate Fossil Beds NM.

IMAGES and TEXT: Pliocene
RELATED TEXT:Began 5 million years ago.
Most life forms of the Pliocene Epoch would have been recognizable to us today. Many individual species were different, but distinguishing characteristics of various animal and plant groups were present. Evidence of wet meadows and of dry, open grassland environments has been found in the Pliocene. Toward the end of this epoch grasslands spread across much of North America, brought on by an ever cooler, ever drier climate. Horses and other hoofed mammals and the powerful, intelligent predators that preyed on them continued to prosper.
IMAGE 1 of 4: Mammut
DESCRIBING: A small, color illustration.
SYNOPSIS: A furry, light-brown, mammoth-like animal lumbers diagonally toward the viewer. Its long elephant-like trunk hangs and curves backward between two, long white tusks that extend from either side of its head below round eyes and large ears. The mammut stands on four thick legs, with semi-circular toenails on its feet. Its left front leg is bent. A short thin tail with a tasseled tip extends behind the mammut.
CAPTION: Mammut was a type of mastodon that migrated to North America in the Pliocene. In the early Pleistocene another elephant group called mammoths joined the mastodons. By the late Pleistocene mastodons and mammoths both became extinct, possibly because of climatic changes or hunting by early people. Found at Hagerman Fossil Beds NM.

IMAGES and TEXT: Pleistocene
RELATED TEXT: Began 2 million years ago.
The Pleistocene Epoch began with widespread migrations of mammals and ended with massive extinctions. It was also a time when glaciers repeatedly covered much of North America. Known evidence of humans living in North America dates to about 12,000 years ago. In this relatively brief period we have had a profound effect on the plants and other animals here. Do we have a responsibility to try to limit our effects on other species, or are humans simply a natural agent of extinction?

Plan Like a Park Ranger: Fuel Up Yourself and Your Vehicle First!
Visitors say we're "in the middle of nowhere." We'd prefer to say we're "halfway to awesomeness!" Make sure you gas up your vehicle and pack a lunch before heading to the Monument. The nearest gas and food is at least 30 miles north or south on Highway 29. We have sheltered picnic tables, but no food or water is sold in the park.
Service Animals are welcomed in all park buildings. All dogs on leash are welcomed on park trails. Dog owners are responsible for picking up after their dogs. A relief area is located to the north of the visitor center parking lot.
Braille brochures and large print exhibit information are available at the front desk of the visitor center. The movie is not audio described; however, the park rangers are trained in audio description and are happy to assist.
