Navahoceros Skeleton
''Odocoileus lucasi'' (historically ''Navahoceros fricki''), known commonly as the American mountain deer, is an extinct species of North American deer. Taxonomy Kurten described a species he called ''Navahoceros fricki'' in 1975. However, his analysis has been questioned on technical grounds and new paleontological data. Kurten's analysis was based on averages of length of dissociated bones (samples sizes 9–52), without specifying the sex or age of the source animals, and without providing standard deviations to let the reader know about variability due to sex and age. One comparative element he used was the skeletal measurements of a single mule deer, but he did not provide the data on sex, age or locality. However, from data provided by Klein (1964) and McMahon (1975), the relative lower leg length of mule deer can vary at least by 22%. Kurten also stated that ''Navahoceros'' resembled ibex (''Capra ibex'') based on short metapodials which made him label the ''Navahoceros ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

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 ...

Hippocamelus
''Hippocamelus'' is a genus of Cervidae, the deer family. It comprises two extant Andean and two fossil species. The living members are commonly known as the huemul (from the Mapuche language), and the taruca. Both species have a stocky, thick, and short-legged body. They live at high altitudes in the summer, then move down the mountains in the fall and spend the winter in sheltered forested valleys. Areas with fresh water are preferred. They are herbivores that feed primarily on herbaceous plants and shrubs as well as sedges, lichens, and grasses found between the rocks on high peaks. They are active during daytime and have a lifespan of about ten years. Extant species The huemul (''Hippocamelus bisulcus''), also known as the South Andean deer, is found in Chile and Argentina. Huemuls live in groups of varying size, typically of two or three individuals, but sometimes as many as eleven. In the past, groups of over a hundred deer were reported. Groups are made up of a femal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomen Nudum
In taxonomy, a ''nomen nudum'' ('naked name'; plural ''nomina nuda'') is a designation which looks exactly like a scientific name of an organism, and may have originally been intended to be one, but it has not been published with an adequate description. This makes it a "bare" or "naked" name, which cannot be accepted as it stands. A largely equivalent but much less frequently used term is ''nomen tantum'' ("name only"). In zoology According to the rules of zoological nomenclature a ''nomen nudum'' is unavailable; the glossary of the ''International Code of Zoological Nomenclature'' gives this definition: And among the rules of that same Zoological Code: In botany According to the rules of botanical nomenclature a ''nomen nudum'' is not validly published. The glossary of the ''International Code of Nomenclature for algae, fungi, and plants'' gives this definition: The requirements for the diagnosis or description are covered by articles 32, 36, 41, 42, and 44.

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/ British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. The ...

Before Present
Before Present (BP) years, or "years before present", is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale. The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must now account for. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation RCYBP stands for the explicit "radio carbon years before present". Usage The BP scale is sometimes used for dates established by means other than radiocarbon dating, such as stratigraphy. This usage differs from t ...

Burnet Cave
Burnet Cave (also known as Rocky Arroyo Cave of Wetmore) is an important archaeological and paleontological site located in Eddy County, New Mexico, United States within the Guadalupe Mountains about 26 miles west of Carlsbad. Physical details The cave has a southern exposure and is reported as being 21 m (70 feet) from the canyon floor. It has an elevation of 1402 m (4600 feet) according to Shultz and Howard (1935). Archaeological finds The cave originally had two walls. They were removed by locals several years before professional excavation began. The locals also dug several 3 foot deep holes and removed several baskets (one containing charred bones), fragments of netting, hide, sandals, and beads. Excavation began in Burnet Cave under returning student E. B. Howard who was working under Alden Mason's Southwestern Expeditions sponsored by the University of Pennsylvania Museum of Anthropology and Archaeology. The first southwestern trip was in 1929 and Bill Burnet showed th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guadalupe Mountains
The Guadalupe Mountains ( es, Sierra de Guadalupe) are a mountain range located in West Texas and southeastern New Mexico. The range includes the highest summit in Texas, Guadalupe Peak, , and the "signature peak" of West Texas, El Capitan, both of which are located within Guadalupe Mountains National Park. The Guadalupe Mountains are bordered by the Pecos River valley and Llano Estacado to the east and north, Delaware Mountains to the south, and Sacramento Mountains to the west. One of the clearest exposures of a prehistoric reef is preserved in the mountain range's bedrock geology. Bedrock contains fossils of reef-dwelling organisms from the Permian period, and the geology is widely studied, mostly by stratigraphers, paleontologists, and Paleoecologists (see geology section). History Archaeological evidence has shown that people lived over 10,000 years ago in and among the many caves and alcoves. The first humans to live here were hunter-gatherers who followed large game ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
