Eobasileus
''Eobasileus cornutus'' ("horned dawn-king") was a prehistoric species of dinocerate mammal. Description About long, and standing some tall at the shoulder, with a weight estimated to be around , ''Eobasilius'' was the largest uintathere. It looked much like the related ''Uintatherium''. Like ''Uintatherium'', it had three pairs of blunt horns on its skull, possibly covered with skin like the ossicones of a giraffe. The frontal pair may have been composed of keratin, like the horn(s) of a rhinoceros. ''Eobasileus'' also had a pair of tusks shielded by bony protrusions of the lower jaw. A dispute over ''Eobasilius'' specifically and the uintatheres more generally helped to spark the Bone Wars between Edward Drinker Cope and Othniel Charles Marsh. Cope, Marsh, and Joseph Leidy independently discovered specimens from related species—though Cope and Marsh believed they had each discovered the same species—in the Fort Bridger area, leading to disputes over naming rights fo ...

Dinocerata
Dinocerata (from the Greek (), "terrible", and (), "horn") is an extinct order of plant-eating hoofed mammals with horns and protuberant canine teeth. Classification A 2015 phylogenetic study recovered Dinocerata as closely related to '' Carodnia'', making them part of the Euungulata assemblage. Taxonomy and phylogeny Most experts place the known genera of Dinocerata within one family, Uintatheriidae, and split it into two subfamilies, Uintatheriinae and Gobiatheriinae. Some experts prefer to split Uintatheriidae into three families, with ''Gobiatherium'' placed in the monogeneric family Gobiatheriidae, the other Eocene genera in Uintatheriidae proper, and the Paleocene genera ''Prodinoceras'' and ''Probathyopsis'' placed in the family "Prodinoceratidae". *Laurasiatheria ** Ungulatomorpha? **Order Dinocerata ***Family Uintatheriidae ****Subfamily Gobiatheriinae *****''Gobiatherium'' ****Subfamily Uintatheriinae *****''Prodinoceras'' *****'' Probathyopsis'' *****''Bathyop ...

Uintatherium
''Uintatherium'' ("Beast of the Uinta Mountains") is an extinct genus of herbivorous mammal that lived during the Eocene epoch. Two species are currently recognized: ''U. anceps'' from the United States during the Early to Middle Eocene (56–38 million years ago) and ''U. insperatus'' of Middle to Late Eocene (48–34 million years ago) China. Description ''Uintatherium'' was a large browsing animal. With a skull long, tall at the shoulder, body length of about and a weight up to 2 tonnes, it was similar to today's rhinoceros, both in size and in shape. Its legs were robust to sustain the weight of the animal and were equipped with hooves. Moreover, a Uintathere's sternum was made up of horizontal segments, unlike today's rhinos, which have compressed vertical segments. Skull Its most unusual feature was the skull, which is both large and strongly built, but simultaneously flat and concave: this feature is rare and, apart from some brontotheres, not regularly characteristic ...

Field Museum
The Field Museum of Natural History (FMNH), also known as The Field Museum, is a natural history museum in Chicago, Illinois, and is one of the largest such museums in the world. The museum is popular for the size and quality of its educational and scientific programs, and its extensive scientific-specimen and artifact collections. The permanent exhibitions, which attract up to two million visitors annually, include fossils, current cultures from around the world, and interactive programming demonstrating today's urgent conservation needs. The museum is named in honor of its first major benefactor, Marshall Field, the department-store magnate. The museum and its collections originated from the 1893 World's Columbian Exposition and the artifacts displayed at the fair. The museum maintains a temporary exhibition program of traveling shows as well as in-house produced topical exhibitions. The professional staff maintains collections of over 24 million specimens and objects tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bone Wars
The Bone Wars, also known as the Great Dinosaur Rush, was a period of intense and ruthlessly competitive fossil hunting and discovery during the Gilded Age of American history, marked by a heated rivalry between Edward Drinker Cope (of the Academy of Natural Sciences of Philadelphia) and Othniel Charles Marsh (of the Peabody Museum of Natural History at Yale). Each of the two paleontologists used underhanded methods to try to outdo the other in the field, resorting to bribery, theft, and the destruction of bones. Each scientist also sought to ruin his rival's reputation and cut off his funding, using attacks in scientific publications. Their search for fossils led them west to rich bone beds in Colorado, Nebraska, and Wyoming. From 1877 to 1892, both paleontologists used their wealth and influence to finance their own expeditions and to procure services and dinosaur bones from fossil hunters. By the end of the Bone Wars, both men had exhausted their funds in the pursuit of paleon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uintathere
Uintatheriidae is a family of extinct ungulate mammals that includes ''Uintatherium''. Uintatheres belong to the order Dinocerata, one of several extinct orders of primitive hoofed mammals that are sometimes united in the Condylarthra. Uintatheres were the largest land animals of their time, surviving from the late Paleocene into the Uintan Epoch of the Middle Eocene. They were heavy animals, with thick legs, massive bones, broad feet, and tiny brains. The most distinctive feature of the great majority of species, however, was the presence of multiple blunt "horns", perhaps similar to the ossicones of modern giraffes, and the presence of large, sabre-like canine teeth. They were eventually replaced as large browsing animals by the even larger brontotheres.

Bridgerian
The Bridgerian North American Stage on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from 50,300,000 to 46,200,000 years BP lasting . It is usually considered to overlap the Ypresian and Lutetian within the Eocene epoch. The Bridgerian is preceded by the Wasatchian and followed by the Uintan NALMA stages. Substages The Bridgerian is considered to contain the following substages: *Twinbuttean: Lower boundary source of the base of the Bridgerian (approximate). *Lutetian which is contained within the Middle Eocene sharing the lower boundary. The Lutetian overlaps with New Zealand's Arnold epoch, Dannevirke epoch, Bortonian While also using the international geologic time scale, many nations–especially those with isolated and therefore non-standard prehistories–use their own systems of dividing geologic time into epochs and faunal stages. In New Zealand, these epo ... stage, and H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossil Taxa Described In 1872
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absol ...

Eocene Mammals Of North America
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulletin Of The Peabody Museum Of Natural History
The Peabody Museum of Natural History at Yale University is among the oldest, largest, and most prolific university natural history museums in the world. It was founded by the philanthropist George Peabody in 1866 at the behest of his nephew Othniel Charles Marsh, the early paleontologist. Most known to the public for its Great Hall of Dinosaurs, which includes a mounted juvenile ''Brontosaurus'' and the mural ''The Age of Reptiles,'' it also has permanent exhibits dedicated to human and mammal evolution; wildlife dioramas; Egyptian artifacts; and the birds, minerals and Native Americans of Connecticut. Description The Peabody Museum is located at 170 Whitney Avenue in New Haven, Connecticut, United States, and is operated by almost one hundred staff members. While the original building was demolished in 1917, it moved to its current location in 1925, and has since expanded to occupy the Peabody Museum, the attached Kline Geology Laboratory and the Class of 1954 Environmental S ...
