Sivaladapidae
Sivaladapidae is an extinct family of adapiform primates from Asia. They survived longer than any other adapiform primate because they were able to shift south as the climate cooled. Their remains date from the Eocene through the Miocene 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 recen ....

Ramadapis
''Ramadapis sahnii'' was a primitive primate belonging to Sivaladapidae that existed around 11 to 14 million years ago ( Early to Mid-Miocene). Only a mandible (a lower jaw bone) was found at the dig site, which was near Ramnagar in Udhampur district in Jammu and Kashmir specifically the lower Siwalik deposits. The jawbone indicates that ''Ramadapis'' resembled a modern day ring-tailed lemur. The early lemur was named after Ashok Sahni, who discovered the first sivaladapid in the Siwalik deposits. The mandible In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower tooth, teeth in place. The mandible sits beneath the maxilla. It is the only movabl ... was only around one and a quarter inch long, which led scientists to assume that it was only around 11 pounds. Ecology The environment that ''Ramadapis sahnii'' lived in is highly disputed upon. It has been hypothesi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adapiformes
Adapiformes is a group of early primates. Adapiforms radiated throughout much of the northern continental mass (now Europe, Asia and North America), reaching as far south as northern Africa and tropical Asia. They existed from the Eocene to the Miocene epoch. Some adapiforms resembled living lemurs. Adapiforms are known from the fossil record only, and it is unclear whether they form a monophyletic or paraphyletic group. When assumed to be a clade, they are usually grouped under the "wet-nosed" taxon Strepsirrhini, which would make them more closely related to the lemurs and less so to the "dry-nosed" Haplorhini taxon that includes monkeys and apes.Callum Ross, Richard F. Kay, ''Anthropoid origins: new visions'', Springer, 2004, , p. 100 In 2009, Franzen and colleagues placed the newly described genus ''Darwinius'' in the "Adapoidea group of early primates representative of early haplorhine diversification" so that, according to these authors, the adapiforms would not be within ...

Siamoadapis
''Siamoadapis'' is an extinct genus of adapiform primate. Remains of its only known species, ''Siamoadapis maemohensis'', were found in Thailand. The fossils were discovered in the lignite layer of a coal mine in Mae Mo district, Lampang Province, northern Thailand, from which it also received its scientific species name. Four lower jaws with teeth were unearthed by a joint team of Thai and French geologists in 2004. It was dated to be 13.1 to 13.3 million years old, and described in 2007 by a team led by geologist Yaowalak Chaimanee (เยาวลักษณ์ ชัยมณี) from the Department of Mineral Resources, Thailand. The animal was a very small primate, with a body length of 15 centimetres and estimated to have weighted 500 grams. Distinct for the species is the small size and differences in the teething compared to other Miocene The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma).

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Miocene Extinctions
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. 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. 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.

Eocene First Appearances
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay.

Prehistoric Strepsirrhines
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
