Menoceras
''Menoceras'' ("Crescent Horns") is a genus of extinct, small rhinoceros endemic to most of southern North America and ranged as far south as Panama during the early Miocene epoch. It lived from around 30.7—19.7 Ma, existing for approximately . Description Male ''Menoceras'' sported two horns side by side at the tip of the nose, whereas the females were hornless. All other rhino genera, save the related genus '' Diceratherium'', have their horns arranged one behind the other. Either gender of ''Menoceros'' grew to a length of long. Paleobiology ''Menoceras'' roamed across a tropical, savanna-like grassland and plains environment that covered much of North America. Because of the massive accumulations of fossil bones of this animal, particularly at Agate Springs Nebraska, ''Menoceras'' may have lived in large herds. Other sites include Martin-Anthony site Martin County, Florida, and Cady Mountains Horse Quarry, San Bernardino County, California. Taxonomy ''Menoceras'' w ...

Rhinoceros
A rhinoceros (; ; ), commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates in the family Rhinocerotidae. (It can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea.) Two of the extant species are native to Africa, and three to South and Southeast Asia. Rhinoceroses are some of the largest remaining megafauna: all weigh at least one tonne in adulthood. They have a herbivorous diet, small brains (400–600 g) for mammals of their size, one or two horns, and a thick (1.5–5 cm), protective skin formed from layers of collagen positioned in a lattice structure. They generally eat leafy material, although their ability to ferment food in their hindgut allows them to subsist on more fibrous plant matter when necessary. Unlike other perissodactyls, the two African species of rhinoceros lack teeth at the front of their mouths; they rely instead on their lips to pl ...

Agate Fossil Beds National Monument
Agate Fossil Beds National Monument is a U.S. National Monument near Harrison, Nebraska. The main features of the monument are a valley of the Niobrara River and the fossils found on Carnegie Hill and University Hill. The area largely consists of grass-covered plains. Plants on the site include prairie sandreed, blue grama, little bluestem and needle and thread grass, and the wildflowers lupin, spiderwort, wallflower, western wallflower and sunflowers. History Originally the Agate Springs Ranch, a working cattle ranch, was owned by Capt. James Cook. The monument's museum collection also contains more than 500 artifacts from the Cook Collection of Plains Indians artifacts. The national monument was authorized on June 5, 1965, but was not established until June 14, 1997. The Harold J. Cook Homestead (Bone Cabin Complex) was listed on the National Register of Historic Places in 1977. Agate Fossil Beds is maintained by the National Park Service. Paleontology The site is best ...

Moropus
''Moropus'' (meaning "slow foot") is an extinct genus of large perissodactyl ("odd-toed" ungulate) mammal in the chalicothere family. They were endemic to North America during the Miocene from ~20.4—13.6 Mya, existing for approximately . ''Moropus'' belonged to the schizotheriine subfamily of chalicotheres, and has the best fossil record of any member of this group; numbers of individuals, including complete skeletons, have been found. The closest extant relatives of ''Moropus'' are other perissodactyls: Equus (genus), horses, Rhinoceros, rhinos, and tapirs. Description Like other chalicothere Chalicotheres (from Greek '' chalix'', "gravel" and '' therion'', "beast") are an extinct clade of herbivorous, odd-toed ungulate (perissodactyl) mammals that lived in North America, Eurasia, and Africa from the Middle Eocene until the Early Plei ...s, ''Moropus'' differed from typical ungulates in having large claws, rather than hooves, on the feet.
