Euprox is an extinct genus of deer that lived in Eurasia during the Miocene.
The type species Euprox furcatus was originally under the genus Prox, but that name was already taken. Depéret assigned it to the related genus Dicrocerus in 1887, before it was assigned to its current placement in 1928. [2] Euprox dicranocerus and Euprox minimus were transferred to the genus soon after; they were originally described as Cervus dicranocerus and Dicracerus minimus, respectively. [3]
Euprox was some of the earliest types of deer known to have true antlers. [4] It would have resembled a muntjac in size and appearance, standing at up to 1 m (3.3 ft) in height.
The antlers of Euprox were short, with two small prongs projecting from the main branch. Euprox is notable for being the earliest deer to possess the presence of a real burr, which are indicative of the border between permanent and deciduous segments of deer antlers. [5] It possessed brachyodont teeth and likely fed on leaves. [4] The environment that Euprox inhabited would have been warm and humid, with many tropical forests. [4] [6]
Ungulates are members of the diverse clade Euungulata which primarily consists of large mammals with hooves. Once part of the clade "Ungulata" along with the clade Paenungulata, "Ungulata" has since been determined to be a polyphyletic and thereby invalid clade based on molecular data. As a result, true ungulates had since been reclassified to the newer clade Euungulata in 2001 within the clade Laurasiatheria while Paenungulata has been reclassified to a distant clade Afrotheria. Living ungulates are divided into two orders: Perissodactyla including equines, rhinoceroses, and tapirs; and Artiodactyla including cattle, antelope, pigs, giraffes, camels, sheep, deer, and hippopotamuses, among others. Cetaceans such as whales, dolphins, and porpoises are also classified as artiodactyls, although they do not have hooves. Most terrestrial ungulates use the hoofed tips of their toes to support their body weight while standing or moving. Two other orders of ungulates, Notoungulata and Litopterna, both native to South America, became extinct at the end of the Pleistocene, around 12,000 years ago.
A deer or true deer is a hoofed ruminant mammal of the family Cervidae. The two main groups of deer are the Cervinae, including muntjac, elk (wapiti), red deer, and fallow deer; and the Capreolinae, including reindeer (caribou), white-tailed deer, roe deer, and moose. Male deer of all species, 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).
Moschidae is a family of pecoran even-toed ungulates, containing the musk deer (Moschus) and its extinct relatives. They are characterized by long 'saber teeth' instead of horns, antlers or ossicones, modest size and a lack of facial glands. While various Oligocene and Miocene pecorans were previously assigned to this family, recent studies find that most should be assigned to their own clades, although further research would need to confirm these traits. As a result, Micromeryx, Hispanomeryx, and Moschus are the only undisputed moschid members, making them known from at least 18 Ma. The group was abundant across Eurasia and North America during the Miocene, but afterwards declined to only the extant genus Moschus by the early Pleistocene.
Musk deer can refer to any one, or all seven, of the species that make up Moschus, the only extant genus of the family Moschidae. Despite being commonly called deer, they are not true deer belonging to the family Cervidae, but rather their family is closely related to Bovidae, the group that contains antelopes, bovines, sheep, and goats. The musk deer family differs from cervids, or true deer, by lacking antlers and preorbital glands also, possessing only a single pair of teats, a gallbladder, a caudal gland, a pair of canine tusks and—of particular economic importance to humans—a musk gland.
Paramachaerodus is an extinct genus of saber-tooth cat of the subfamily Machairodontinae, which was endemic to Europe and Asia during the late Miocene from 15 to 9 Ma.
The Antilocapridae are a family of artiodactyls endemic to North America. Their closest extant relatives are the giraffids. Only one species, the pronghorn, is living today; all other members of the family are extinct. The living pronghorn is a small ruminant mammal resembling an antelope.
Amphicyon is an extinct genus of large carnivorans belonging to the family Amphicyonidae, subfamily Amphicyoninae, from the Miocene epoch. Members of this family received their vernacular name for possessing bear-like and dog-like features. They ranged over North America, Europe, Asia, and Africa.
Eucladoceros or bush-antlered deer is an extinct genus of deer whose fossils have been discovered in Europe, the Middle East and Central Asia. This genus was formally described by Hugh Falconer in 1868.
Dicrocerus elegans is an extinct species of deer found in France, Europe. Dicrocerus probably came from Asia, from the region where true deer are believed to have originated and evolved. It inhabited forests in the temperate belt and in Europe it was typical of the Miocene. It died out at the beginning of Pliocene without leaving any descendants.
Protoceratidae is an extinct family of herbivorous North American artiodactyls that lived during the Eocene through Pliocene. While early members of the group were hornless, in later members males developed elaborate cranial oramentation. They are variously allied with Ruminantia or Tylopoda.
Agnotherium is a genus of large sized carnivoran mammals, belonging to the Amphicyonidae, which has been found in Western Europe, and possibly China and Northern Africa, and lived during the Late Miocene epoch. Despite only being known from fragmentary remains, the genus notable for hypercarnivorous adaptions, which have been said to represent the "apex" among its family.
Gobicyon is an extinct genus of large-sized carnivoran mammals, belonging to the Amphicyonidae, that was discovered in China, Mongolia, and Serbia, and lived during the Middle Miocene epoch. Despite only being known from rather fragmentary remains, recent discoveries showcase that it was an aberrant member of the subfamily Haplocyoninae, with adaptions towards bone-crushing similar to those of a hyaena.
Rucervus is a genus of deer from India, Nepal, Indochina, and the Chinese island of Hainan. The only extant representatives, the barasingha or swamp deer and Eld's deer, are threatened by habitat loss and hunting; another species, Schomburgk’s deer, went extinct in 1938. Deer species found within the genus Rucervus are characterized by a specific antler structure, where the basal ramification is often supplemented with an additional small prong, and the middle tine is never present. The crown tines are inserted on the posterior side of the beam and may be bifurcated or fused into a small palmation.
Dama is a genus of deer in the subfamily Cervinae, commonly referred to as fallow deer.
Uteodon is a genus of herbivorous iguanodontian dinosaur. It is a basal iguanodontian which lived during the late Jurassic period in what is now Uintah County, Utah. It is known from the middle of the Brushy Basin Member, Morrison Formation. The genus was named by Andrew T. McDonald in 2011 and the type species is U. aphanoecetes.

Croizetoceros is an extinct genus of deer which lived throughout much of Europe, first appearing during the last stages of the Miocene and living until the Early Pleistocene.
Comptonia columbiana is an extinct species of sweet fern in the flowering plant family Myricaceae. The species is known from fossil leaves found in the early Eocene deposits of central to southern British Columbia, Canada, plus northern Washington state, United States, and, tentatively, the late Eocene of Southern Idaho and Earliest Oligocene of Oregon, United States.
Amphiprox is an extinct genus of early deer from the Miocene of Europe.
Dihoplus is an extinct genus of rhinoceros that lived in Eurasia from the Late Miocene to Pliocene.
