Syndyoceras
''Syndyoceras'' is a small extinct genus of Artiodactyla, of the family Protoceratidae, endemic to central North America from the Miocene epoch (24.8—20.6 Ma), existing for approximately . Taxonomy ''Syndyoceras'' was named by Barbour (1905). Its type is ''Syndyoceras cooki''. It was assigned to Protoceratidae by Barbour (1905) and Carroll (1988); and to Kyptoceratini by Webb (1981), Prothero (1998), Webb ''et al.'' (2003) and Prothero and Ludtke (2007). Morphology The skull decoration of ''Syndyoceras'' looked quite unlike those of a deer. It had two pairs of horns. The first was a V-shaped pair on the snout, fused at the base. The second pair was placed between the eyes and the ears and was curved inwards, the horns facing towards each other in a semicircular shape. Like giraffe ossicones, these protrusions were covered with skin. They were probably used for display and fighting. In addition to the horns, ''Syndyoceras'' also possessed tusk-like canine teeth, that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protoceratidae
Protoceratidae is an extinct family of herbivorous North American artiodactyls (even-toed ungulates) that lived during the Eocene through Pliocene at around 46.2—4.9 Mya, existing for about 41 million years. Classification Protoceratidae was erected by Othniel Charles Marsh in 1891, with the type genus '' Protoceras'' and assigned to the Artiodactyla. It was later assigned to Pecora, and more recently to Ruminantia or Tylopoda. However, recently a relationship to chevrotains in the infraorder Tragulina has been proposed. Morphology When alive, protoceratids would have resembled deer, though they were not directly related. Protoceratids ranged from 1 to 2 m in length, from about the size of a roe deer to an elk. Unlike many modern ungulates, they lacked cannon bones in their legs. Their dentition was similar to that of modern deer and cattle, suggesting they fed on tough grasses and similar foods, with a complex stomach similar to that of camels. At least some forms are believe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deer
Deer or true deer are hoofed ruminant mammals forming the family Cervidae. The two main groups of deer are the Cervinae, including the muntjac, the elk (wapiti), the red deer, and the fallow deer; and the Capreolinae, including the reindeer (caribou), white-tailed deer, the roe deer, and the moose. Male deer of all species (except the water deer), as well as female reindeer, grow and shed new antlers each year. In this they differ from permanently horned antelope, which are part of a different family (Bovidae) within the same order of even-toed ungulates (Artiodactyla). The musk deer (Moschidae) of Asia and chevrotains (Tragulidae) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia; they are not especially closely related to Cervidae. Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in heraldry, such as ...

Kyptoceratini
Kyptoceratini is an extinct tribe of the subfamily Synthetoceratinae, deer-like mammals within the family Protoceratidae belonging to the order Artiodactyla, endemic to North America during the Miocene through Pliocene, living 23.03—3.6 Ma, existing for approximately . Taxonomy Kyptoceratini is a sister taxa to Synthetoceratini. Kyptoceratini was named by Webb (1981). Its type is ''Kyptoceras''.

Erwin Hinckly Barbour
Erwin Hinckley Barbour (April 5, 1856 – May 10, 1947) was an American geologist and paleontologist. He was born near Oxford, Ohio, and was educated at Miami University and at Yale, where he graduated in 1882. He was assistant paleontologist to the United States Geological Survey under Othniel Charles Marsh from 1882 to 1888. He then taught at the University of Iowa for two years, before being hired by the University of Nebraska in 1891 as head of the Department of Geology. Upon his arrival in at the University of Nebraska, he worked vigorously to equip his department and to start populating the University museum. Within a year, he was appointed Curator of the University of Nebraska State Museum. He remained the director until 1941. Also in 1891, he was appointed by Governor Thayer as Acting State Geologist, a position he also retained for many years. Barbour gave his time free for the next 25 summers to manage field parties throughout the state, surveying the geological and p ...

Chattian Genus First Appearances
The Chattian is, in the geologic timescale, the younger of two ages or upper of two stages of the Oligocene Epoch/Series. It spans the time between . The Chattian is preceded by the Rupelian and is followed by the Aquitanian (the lowest stage of the Miocene). Stratigraphic definition The Chattian was introduced by Austrian palaeontologist Theodor Fuchs in 1894. Fuchs named the stage after the Chatti, a Germanic tribe.Berry, Edward W"The Mayence Basin, a Chapter of Geologic History" ''The Scientific Monthly'', Vol. 16, No. 2, February 1923. pp. 114. Retrieved March 18, 2020. The original type locality was near the German city of Kassel. The base of the Chattian is at the extinction of the foram genus ''Chiloguembelina'' (which is also the base of foram biozone P21b). An official GSSP for the Chattian Stage was ratified in October of 2016. The top of the Chattian Stage (which is the base of the Aquitanian Stage, Miocene Series and Neogene System) is at the first appearance of ...

Miocene Mammals Of North America
The Miocene ( ) is the first geological epoch of the Neogene The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period Mya. ... Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch.

The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch.
