Eosimias
''Eosimias'' is a genus of early primates, first discovered and identified in 1999 from fossils collected in the Shanghuang fissure-fillings of Liyang, the southern city of Jiangsu Province, China. It is a part of the family Eosimiidae, and includes three known species: ''Eosimias sinensis'', ''Eosimias centennicus'', and ''Eosimias dawsonae''. It provides us with a glimpse of a primate skeleton similar to that of the common ancestor of the Haplorhini (including all simians). The name ''Eosimias'' is designed to mean "dawn monkey", from Greek ''eos'' "dawn" and Latin ''simius'' "monkey". Dating has proven this genus lived from 45 to 40 million years ago in the middle Eocene. The genus ''Eosimias'' is unique because of the presence of primitive and derived traits. It provides new insight into the phylogenetic relationships between simians and prosimians (especially the phylogenetic position of the haplorhine prosimian tarsiers). It can best be described as a likely tree dweller th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eosimiidae
Eosimiidae is the possible family of extinct primates believed to be the earliest simians. Taxonomy When they were discovered the possibility that Eosimians were outside and ancestral to Simians was considered (Culotta 1992), but subsequent work showed them to be Simians (Kay et al. 1997, Ross et al. 1998). Some scholars continue to question whether the eosimiids are simians, as they seem closer to Tarsiiformes - Gunnell and Miller (2001), for instance, found that eosimiid morphology didn't match up to anthropoid (simian) morphology.Primate Adaptation and Evolution: 3rd Edition, Ch. 13, p 279-281 However, most experts now place Eosimians as stem simians - Williams, Kay and Kirk (2010) note this is because more and more evidence points in that direction. Williams, Kay and Kirk note that (as at late 2009), accounting for all proposed species, there would be 11 species in total in 6 genera (Amphipithecidae, '' Anthrasimias'', '' Bahinia'', ''Eosimias'', '' Phenacopithecus'', '' ...

Simian
The simians, anthropoids, or higher primates are an infraorder (Simiiformes ) of primates containing all animals traditionally called monkeys and apes. More precisely, they consist of the parvorders New World monkeys (Platyrrhini) and Catarrhini, the latter of which consists of the superfamilies Cercopithecidae (Old World monkeys in the stricter sense) and apes (Hominoidea; including the genus ''Homo (genus), Homo''). The simians are sister group to the Tarsiiformes, tarsiers (Tarsiiformes), together forming the Haplorhini, haplorhines. The radiation occurred about 60 million years ago (during the Cenozoic era); 40 million years ago, simians colonized South America, giving rise to the New World monkeys. The remaining simians (catarrhines) split about 25 million years ago into Old World monkey, Cercopithecidae and apes (including humans). Taxonomy and evolution In earlier classification, New World monkeys, Old World monkeys, apes, and humans – collectively known as simians or ...

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 ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Myanmar
Myanmar, ; UK pronunciations: US pronunciations incl. . Note: Wikipedia's IPA conventions require indicating /r/ even in British English although only some British English speakers pronounce r at the end of syllables. As John C. Wells, John Wells explains, the English spellings of both Myanmar and Burma assume a non-rhotic variety of English, in which the letter r before a consonant or finally serves merely to indicate a long vowel: [ˈmjænmɑː, ˈbɜːmə]. So the pronunciation of the last syllable of Myanmar as [mɑːr] or of Burma as [bɜːrmə] by some speakers in the UK and most speakers in North America is in fact a spelling pronunciation based on a misunderstanding of non-rhotic spelling conventions. The final ''r'' in ''Myanmar'' was not intended for pronunciation and is there to ensure that the final a is pronounced with the broad a, broad ''ah'' () in "father". If the Burmese name my, မြန်မာ, label=none were spelled "Myanma" in English, this would b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biostratigraphy
Biostratigraphy is the branch of stratigraphy which focuses on correlating and assigning relative ages of rock Stratum, strata by using the fossil assemblages contained within them.Hine, Robert. “Biostratigraphy.” ''Oxford Reference: Dictionary of Biology'', 8th ed., Oxford University Press, 2019. The primary objective of biostratigraphy is ''correlation'', demonstrating that a particular Horizon (geology), horizon in one geological section represents the same period of time as another horizon at a different section. Fossils within these strata are useful because sediments of the same age can look completely different, due to local variations in the Sedimentary depositional environment, sedimentary environment. For example, one section might have been made up of clays and marls, while another has more chalky limestones. However, if the fossil species recorded are similar, the two sediments are likely to have been laid down around the same time. Ideally these fossils are used to ...

Shanxi
Shanxi (; ; formerly romanised as Shansi) is a landlocked province of the People's Republic of China and is part of the North China region. The capital and largest city of the province is Taiyuan, while its next most populated prefecture-level cities are Changzhi and Datong. Its one-character abbreviation is "" (), after the state of Jin that existed there during the Spring and Autumn period. The name ''Shanxi'' means "West of the Mountains", a reference to the province's location west of the Taihang Mountains. Shanxi borders Hebei to the east, Henan to the south, Shaanxi to the west and Inner Mongolia to the north. Shanxi's terrain is characterised by a plateau bounded partly by mountain ranges. Shanxi's culture is largely dominated by the ethnic Han majority, who make up over 99% of its population. Jin Chinese is considered by some linguists to be a distinct language from Mandarin and its geographical range covers most of Shanxi. Both Jin and Mandarin are spoken in Shanx ...
