Procamelus
''Procamelus'' is an extinct genus of camel endemic to North America. It lived from the Middle to Late Miocene 16.0—5.3 mya, existing for approximately . The name is derived from the Greek πρό, meaning "before" or denoting priority of order, and κάμελος ("camel"), thus meaning "fore-camel", "early camel" or "predecessor camel". It had long legs designed for speed, and was about in height at the shoulder, slightly smaller than a modern llama. Unlike modern camelids, it had a pair of small incisor teeth in the upper jaw. The remaining teeth were large and adapted for eating tough vegetation. The shape of the toes suggests that it possessed foot pads, like modern camels, unlike earlier forms of camelid, which generally had hooves. This would have helped it walk over relatively soft ground. It had a straighter neck than ''Oxydactylus'' or ''Aepycamelus ''Aepycamelus'' is an extinct genus of camelids that lived during the Miocene 20.6–4.9 million years ago, exist ...

Alticamelus
''Aepycamelus'' is an extinct genus of camelids that lived during the Miocene 20.6–4.9 million years ago, existing for about . Its name is derived from the Homeric Greek , "high and steep" and κάμηλος – "camel"; thus, "high camel"; ''alticamelus'' in Latin. ''Aepycamelus'' spp. walked on their toes only. Unlike earlier species of camelids, they possessed cushioned pads like those of modern camels. Taxonomy ''Aepycamelus'' was formerly referred to the genus ''Alticamelus'', which Matthew (1901) erected for ''"Procamelus" altus'' Marsh, 1894, a camel species described from a calcaneum found in Neogene deposits in Oregon, after he referred a complete skeleton of a tall camel from Colorado to that species. Matthew and Cook (1909) erected ''Alticamelus giraffinus'' for the Colorado specimen after recognizing the ''A. altus'' holotype as indeterminate. MacDonald (1956) recognized ''Alticamelus'' as a'' nomen dubium'' and erected ''Aepycamelus'' for species previously assigne ...

Middle Miocene
The Middle Miocene is a sub-epoch of the Miocene Epoch made up of two stages: the Langhian and Serravallian stages. The Middle Miocene is preceded by the Early Miocene. The sub-epoch lasted from 15.97 ± 0.05 Ma to 11.608 ± 0.005 Ma (million years ago). During this period, a sharp drop in global temperatures took place. This event is known as the Middle Miocene Climate Transition. For the purpose of establishing European Land Mammal Ages The European Land Mammal Mega Zones (abbreviation: ELMMZ, more commonly known as European land mammal ages or ELMA) are zones in rock layers that have a specific assemblage of fossils (biozones) based on occurrences of fossil assemblages of Europe ... this sub-epoch is equivalent to the Astaracian age.

Oxydactylus
''Oxydactylus'' is an extinct genus of camelid endemic to North America. It lived from the Late Oligocene to the Middle Miocene (28.4–13.7 mya), existing for approximately . The name is from the Ancient Greek οξύς (oxys, "sharp")and δάκτυλος (daktylos, "finger"). They had very long legs and necks, and were probably adapted to eating high vegetation, much like modern giraffes The giraffe is a large African hoofed mammal belonging to the genus ''Giraffa''. It is the tallest living terrestrial animal and the largest ruminant on Earth. Traditionally, giraffes were thought to be one species, ''Giraffa camelopardalis .... Unlike modern camelids, they had hooves, rather than tough sole-pads, and splayed toes.

The Clarendonian North American Stage on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from 13,600,000 to 10,300,000 years BP, a period of . It is usually considered to overlap the Serravallian age of the Middle Miocene and the Tortonian age of the Late Miocene.

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] |

The Miocene ( ) is the first geological epoch of the Neogene 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.

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. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Prehistoric Even-toed Ungulate 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. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
