Pediomeryx
''Pediomeryx'' is an extinct genus of artiodactyl, of the family Dromomerycidae, endemic to North America. It lived during the Late Miocene 10.3—4.9 Ma, existing for approximately . Fossils have been recovered from the Midway Site in Florida, the Gray Fossil Site in northeast Tennessee, several sites in Nebraska and Wyoming, Saskatchewan, and Boron, California. They were comparable in size to red deer The red deer (''Cervus elaphus'') is one of the largest deer species. A male red deer is called a stag or hart, and a female is called a hind. The red deer inhabits most of Europe, the Caucasus Mountains region, Anatolia, Iran, and parts of wes ..., with most specimens weighing 100–200 kg but surpassing 400 kg in the case of ''P. figginsi''.

Dromomerycidae
The Dromomerycidae is an extinct family of Neogene ruminants belonging to the infraorder Pecora. Dromomerycids, known by two subfamilies, were endemic to North America from the later early Miocene up to the early Pliocene (~5 Ma), leaving no descendants. Dromomerycidae has a long history of uncertain taxonomic affiliations due to its superficial resemblances with the Eurasian Neogene Palaeomerycidae and were traditionally classified as subfamilies within the family. However, recent research differentiates the dromomerycids from the Giraffomorpha (Giraffoidea and Palaeomerycoidea) by the lack of sutures on the skull roof that typically make up the ossicones of the later clade. The similar resemblances of the appendages therefore could be the result of parallel evolution. The dromomerycids are characterized by unbranched and nondeciduous appendages above the orbits of the eyes. These traits may have been typically characteristic of males but appear to have been present in both ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gray Fossil Site
The Gray Fossil Site is an Early Pliocene assemblage of fossils dating between 4.5 and 4.9 million years old, located near the town of Gray in Washington County, Tennessee. The site was discovered during a widening project of Tennessee State Route 75 by the Tennessee Department of Transportation in May 2000, after which local officials decided to preserve the site for research and education. The site became part of East Tennessee State University, and the Gray Fossil Site & Museum was opened on the site in 2007. The ancient habitat of the Gray Fossil Site was a pond formed within a sinkhole surrounded by a warm, wet forest. The fossils found at the site represent the ancient plants and animals that lived and died in and around the sinkhole pond. As the first site of its age known from the Appalachian region, the Gray Fossil Site is a unique window into the past. Research at the site has yielded many surprising discoveries, including new species of red panda, rhinoceros, pond tur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeomerycidae
The Palaeomerycidae are an extinct family of ruminants in the order Artiodactyla. Palaeomerycids lived in North America, Europe, Africa and Asia from 33 to 4.9 million years ago (from the Late Eocene to Pliocene epochs), existing for about 28 million years; one species was also reported from South America, but its identity as a palaeomerycid was subsequently disputed. Specimens of '' Amphitragulus'', the earliest known genus, have been found in Aragon (Spain), Ronheim (Germany), Sardinia (Italy), France, and Kazakhstan and range from 33 to 15.97 million years old. Fossils of '' Lagomeryx'' and ''Palaeomeryx feignouxi'' were recovered in Germany and Slovakia from the Middle Eocene. The oldest known North American specimen, '' Barbouromeryx'', was discovered in Scotts Bluff, Nebraska, and estimated at 23.03 million years old. Palaeomerycids such as ''Cranioceras'' and other Dromomerycinae continued to live in North America until the early Pliocene. Description Palaeomerycids w ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Prehistoric Artiodactyla Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

Zanclean Extinctions
The Zanclean is the lowest stage or earliest age on the geologic time scale of the Pliocene. It spans the time between 5.332 ± 0.005 Ma (million years ago) and 3.6 ± 0.005 Ma. It is preceded by the Messinian Age of the Miocene Epoch, and followed by the Piacenzian Age. The Zanclean can be correlated with regionally used stages, such as the Opoitian of New Zealand, and the Tabianian or Dacian of Central Europe. It also corresponds to the late Hemphillian to mid-Blancan North American Land Mammal Ages. In California, the Zanclean roughly corresponds to the middle part of the Delmontian stage. Definition The Zanclean Stage was introduced by Giuseppe Seguenza in 1868. It is named after ''Zancle'', the pre-Roman name for the Italian city of Messina on Sicily. The base of the Zanclean (and the Pliocene Series) lies with the top of magnetic chronozone Cr3 (about 100,000 years before the Thvera normal subchronozone C3n.4n). The base is also close to the extinction level of the calca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Deer
The red deer (''Cervus elaphus'') is one of the largest deer species. A male red deer is called a stag or hart, and a female is called a hind. The red deer inhabits most of Europe, the Caucasus Mountains region, Anatolia, Iran, and parts of western Asia. It also inhabits the Atlas Mountains of Northern Africa; its early ancestors are thought to have crossed over to Morocco, then to Algeria, Libya and Tunisia via the Strait of Gibraltar, becoming the only species of true deer (Cervidae) to inhabit Africa. Red deer have been introduced to other areas, including Australia, New Zealand, the United States, Canada, Peru, Uruguay, Chile and Argentina. In many parts of the world, the meat (venison) from red deer is used as a food source. Red deer are ruminants, characterized by a four-chambered stomach. Genetics, Genetic evidence indicates that the red deer, as traditionally defined, is a species group, rather than a single species, though exactly how many species the group includes rem ...
