The moose or elk is the only species in the genus Alces. The moose is the tallest, and the second-largest, land animal in North America, only falling short of the American bison, in terms of mass. It is the world's tallest, largest and heaviest extant species of deer. Most adult male moose have distinctively broad, palmate antlers; other members of the deer family have antlers with a dendritic ("twig-like"), pointed configuration. Moose are winter specialists, and typically inhabit the circumpolar boreal forests or temperate broadleaf and mixed forests of the Northern Hemisphere, thriving in cooler, temperate areas as well as subarctic climates.
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).
The Irish elk, also called the giant deer or Irish deer, is an extinct species of deer in the genus Megaloceros and is one of the largest deer that ever lived. Its range extended across Eurasia during the Pleistocene, from Ireland to Lake Baikal in Siberia. The most recent remains of the species have been radiocarbon dated to about 7,700 years ago in western Russia. Its antlers, which can span 3.5 metres (11 ft) across are the largest known of any deer. It is not closely related to either living species called the elk, with it being widely agreed that its closest living relatives are fallow deer (Dama).
Megaloceros is an extinct genus of deer whose members lived throughout Eurasia from the Pleistocene to the early Holocene. The type and only undisputed member of the genus, Megaloceros giganteus, vernacularly known as the "Irish elk" or "giant deer", is also the best known. Fallow deer are thought to be their closest living relatives. Megaloceros is thought to be closely related to the East Asian genus Sinomegaceros, as well as possibly other extinct genera of "giant deer".
Gomphotheres are an extinct group of proboscideans related to modern elephants. They were widespread across Afro-Eurasia and North America during the Miocene and Pliocene epochs and dispersed into South America during the Pleistocene as part of the Great American Interchange. Gomphotheres are a paraphyletic group that is ancestral to Elephantidae, which contains modern elephants, as well as Stegodontidae. While most famous forms such as Gomphotherium had long lower jaws with tusks, which is the ancestral condition for the group, some later members developed shortened (brevirostrine) lower jaws with either vestigial or no lower tusks, looking very similar to modern elephants, an example of parallel evolution, which outlasted the long-jawed gomphotheres. By the end of the Early Pleistocene, gomphotheres became extinct in Afro-Eurasia, with the last two genera, Cuvieronius ranging from southern North America to western South America, and Notiomastodon having a wide range over most of South America until the end of the Pleistocene around 12,000 years ago, when they became extinct following the arrival of humans.
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.
Libralces was a genus of Eurasian deer that lived during the Pliocene epoch. Its main claim to fame is its 2+ meter wide antlers, comparable in size to those of Megaloceros.
Cervalces scotti, also known as stag-moose, is an extinct species of large deer that lived in North America during the Late Pleistocene epoch. It is the only known North American member of the genus Cervalces. Its closest living relative is the modern moose.
The Capreolinae, Odocoileinae, or the New World deer are a subfamily of deer. Alternatively, they are known as the telemetacarpal deer, due to their bone structure being different from the plesiometacarpal deer subfamily Cervinae. The telemetacarpal deer maintain their distal lateral metacarpals, while the plesiometacarpal deer maintain only their proximal lateral metacarpals. The Capreolinae are believed to have originated in the Middle Miocene, between 7.7 and 11.5 million years ago, in Central Asia.
Xenocyon is an extinct group of canids, either considered a distinct genus or a subgenus of Canis. The group includes Canis (Xenocyon) africanus, Canis (Xenocyon) antonii and Canis (Xenocyon) falconeri that gave rise to Canis (Xenocyon) lycanoides. The hypercarnivorous Xenocyon is thought to be closely related and possibly ancestral to modern dhole and the African wild dog, as well as the insular Sardinian dhole.
Odocoileus lucasi, known commonly as the American mountain deer, is an extinct species of North American deer.
A gazelle is one of many antelope species in the genus Gazella. There are also seven species included in two further genera; Eudorcas and Nanger, which were formerly considered subgenera of Gazella. A third former subgenus, Procapra, includes three living species of Asian gazelles.
Cervalces carnutorum, sometimes known as Alces carnutorum, is an extinct species of large deer that lived in Europe during the Early Pleistocene. Fragments were found in the site of Saint-Prest, near Chartres, and described by Laugel in 1862.
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.
Stephanorhinus is an extinct genus of two-horned rhinoceros native to Eurasia and North Africa that lived during the Late Pliocene to Late Pleistocene. Species of Stephanorhinus were the predominant and often only species of rhinoceros in much of temperate Eurasia, especially Europe, for most of the Pleistocene. The last two species of Stephanorhinus – Merck's rhinoceros and the narrow-nosed rhinoceros – went extinct during the last glacial period.
Dama is a genus of deer in the subfamily Cervinae, commonly referred to as fallow deer.
The Yukon Beringia Interpretive Centre is a research and exhibition facility located at km 1423 on the Alaska Highway in Whitehorse, Yukon, which opened in 1997. The focus of the interpretive centre is the story of Beringia, the 3200 km landmass stretching from the Kolyma River in Siberia to the MacKenzie River in Canada, which remained non-glaciated during the Pleistocene due to light snowfall from an arid climate. Beringia is of special interest to archeologists and paleontologists as it played a crucial role in the migrations of many animals and humans between Asia and the Americas. The term Beringia was first coined by the Swedish botanist Eric Hultén in 1937.
The Alaska moose, or Alaskan moose in Alaska, or giant moose and Yukon moose in Canada, is a subspecies of moose that ranges from Alaska to western Yukon. The Alaska moose is the largest subspecies of moose. Alaska moose inhabit boreal forests and mixed deciduous forests throughout most of Alaska and most of Western Yukon. Like all moose subspecies, the Alaska moose is usually solitary but sometimes will form small herds. Typically, they only come into contact with other moose for mating or competition for mates. Males and females select different home ranges during different seasons. This leads to spatial segregation throughout much of the year. While males and females are spatially separate the habitat that they occupy is not significantly different. During mating season, in autumn and winter, male Alaska moose become very aggressive and prone to attacking when startled.
Cervalces latifrons, the broad-fronted moose, or the giant moose was a giant species of deer that inhabited the Europe and Asia during the Pleistocene epoch. It is thought to be the ancestor of the modern moose, as well as the extinct North American Cervalces scotti. It was considerably larger than living moose, placing it as one of the largest deer to have ever lived.
Alceini is a tribe of deer, containing the extant genus Alces and the extinct genera Cervalces and Libralces.
