Mececyon Trinilensis
''Mececyon trinilensis'', the Trinil dog, is an extinct canid species that lived in Indonesia during the Pleistocene. Description The body size of ''Mececyon trinilensis'' been estimated to be about 22 kg. This size is the result of insular dwarfism. Habitat and ecology ''Mececyon trinilensis'' is endemic to the island of Java. It was part of the Pleistocene Trinil Fauna of Java. Other animals of this Faunal assemblage were '' Bos palaesondaicus'', the Indian muntjak (''Muntiacus muntjak''), '' Bubalus palaeokerabau'', the Dubois santeng and ''Stegodon trigonocephalus''. Other predators of the Trinil Fauna were the Trinil tiger (''Panthera tigris trinilensis'') and the leopard cat (''Prionailurus bengalensis'').Christine Hertler/ Yan Rizal (2005): Excursion guide to the Pleistocene Hominid Sites in Central and East Java, Johann Wolfgang Geothe-Universität, Frankfurt am Main, Germany/ ITB, Bandung, Indonesia It has been estimated that ''Mececyon trinilensis'' hunted ...

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 ...

Trinil Tiger
''Panthera tigris trinilensis'', known as the Trinil tiger, is an extinct tiger subspecies dating from about 1.2 million years ago that was found at the locality of Trinil, Java, Indonesia. The fossil remains are now stored in the Dubois Collection of the National Museum of Natural History in Leiden, the Netherlands. Although these fossils have been found on Java, the Trinil tiger is probably not a direct ancestor of the Javan tiger. The Trinil tiger probably became extinct 50,000 years ago. The Bali tiger was also not closely related to the Trinil because of their time differences. It lived in Indonesia, particularly in Java and Trinil, and according to some zoologists, it could be the ancestor of all known Indonesian subspecies. Perhaps, East Asia was a center of the origin of Pantherinae. The oldest tiger fossils found in Early Pleistocene Java show that about two million years ago, tigers were already quite common in East Asia. However, the glacial and interglacial climatic ...

Prehistoric Canines
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] |
Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.

Dhole
The dhole (''Cuon alpinus''; ) is a canid native to Central, South, East and Southeast Asia. Other English names for the species include Asian wild dog, Asiatic wild dog, Indian wild dog, whistling dog, red dog, red wolf, and mountain wolf. It is genetically close to species within the genus ''Canis'', but distinct in several anatomical aspects: its skull is convex rather than concave in profile, it lacks a third lower molar and the upper molars sport only a single cusp as opposed to between two and four. During the Pleistocene, the dhole ranged throughout Asia, Europe and North America but became restricted to its historical range 12,000–18,000 years ago. The dhole is a highly social animal, living in large clans without rigid dominance hierarchies and containing multiple breeding females. Such clans usually consist of about 12 individuals, but groups of over 40 are known. It is a diurnal pack hunter which preferentially targets large and medium-sized ungulates. I ...

African Wild Dog
The African wild dog (''Lycaon pictus''), also called the painted dog or Cape hunting dog, is a wild canine which is a native species to sub-Saharan Africa. It is the largest wild canine in Africa, and the only extant member of the genus '' Lycaon'', which is distinguished from ''Canis'' by dentition highly specialised for a hypercarnivorous diet, and by a lack of dewclaws. It is estimated that about 6,600 adults (including 1,400 mature individuals) live in 39 subpopulations that are all threatened by habitat fragmentation, human persecution, and outbreaks of disease. As the largest subpopulation probably comprises fewer than 250 individuals, the African wild dog has been listed as endangered on the IUCN Red List since 1990. The species is a specialised diurnal hunter of antelopes, which it catches by chasing them to exhaustion. Its natural enemies are lions and spotted hyenas: the former will kill the dogs where possible, whilst hyenas are frequent kleptoparasites. Like ot ...

Sardinian Dhole
The Sardinian dhole (''Cynotherium sardous'') is an extinct insular canid which was endemic to what is now the Mediterranean islands of Sardinia (Italy) and Corsica (France), which were joined for much of the Pleistocene. It went extinct when humans began to settle on the island. Its scientific name means "dog-beast of Sardinia", the genus name from the and and the specific name from the , alt. form of . The oldest fossils of the ''Cynotherium'' lineage on Sardinia, belonging to the species ''Cynotherium malatestai'' likely ancestral to ''C. sardous'' date to the Early-Middle Pleistocene transition, corresponding to faunal turnover between the older '' Nesogoral'' Faunal Complex and the younger ''Microtus'' ('' Tyrrhenicola'') faunal complex. The genomic analysis of a 21,000 year-old Sardinian dhole specimen indicates that the Sardinian dhole lineage and the Asian dhole lineage diverged from each other 885,000 years ago. Gene flow continued between the two lineages until b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megacyon Merriami
''Megacyon merriami'', or Merriam's dog, was a prehistoric canid that lived in the early/middle Pleistocene (about 800-300 thousand years ago). Its fossilized remains have been found on the island of Java. Its scientific name means "Merriam's large dog". Description The fossil remains of this canid are incomplete, hence they do not provide an accurate reconstruction. The species appears to have been diverged from ''Xenocyon'', along with the African wild dog, Sardinian dhole and ''Mececyon trinilensis'', another extinct Javanese canid. The Merriam's dog had a set of strong, robust teeth. Its size probably exceeded that of the extant African wild dog The African wild dog (''Lycaon pictus''), also called the painted dog or Cape hunting dog, is a wild canine which is a native species to sub-Saharan Africa.

Xenocyon
''Xenocyon'' ("strange dog") is an extinct subgenus of ''Canis''. The group includes ''Canis'' (''Xenocyon'') ''africanus'', ''Canis'' (''Xenocyon'') ''antonii'' and ''Canis'' (''Xenocyon'') ''falconeri'' that gave rise to ''Canis'' (''Xenocyon'') ''lycanoides''. The hypercarnivorous ''Xenocyon'' gave rise to the modern dhole and the African wild dog. Taxonomy ''Xenocyon'' is proposed as a subgenus of ''Canis'' named ''Canis'' (''Xenocyon''). One taxonomic authority proposes that as part of this subgenus, the group named ''Canis'' (''Xenocyon'') ex gr. ''falconeri'' (ex gr. meaning "of the group including") would include all of the large hypercarnivorous canids that inhabited the Old World during the Late Pliocene–Early Pleistocene: ''Canis'' (''Xenocyon'') ''africanus'' in Africa, ''Canis'' (''Xenocyon'') ''antonii'' in Asia and ''Canis'' (''Xenocyon'') ''falconeri'' in Europe. Further, these three could be regarded as extreme geographical variations within the one taxon. Thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leopard Cat
The leopard cat (''Prionailurus bengalensis'') is a small wild cat native to continental South, Southeast, and East Asia. Since 2002 it has been listed as Least Concern on the IUCN Red List as it is widely distributed although threatened by habitat loss and hunting in parts of its range. Historically, the leopard cat of continental Asia was considered the same species as the Sunda leopard cat. As of 2017, the latter is recognised as a distinct species, with the taxonomic name ''Prionailurus javanensis''. Leopard cat subspecies differ widely in fur colour, tail length, skull shape and size of carnassials. Archaeological evidence indicates that the leopard cat was the first cat species domesticated in Neolithic China about 5,000 years ago in Shaanxi and Henan Provinces. Characteristics A leopard cat is about the size of a domestic cat, but more slender, with longer legs and well-defined webs between its toes. Its small head is marked with two prominent dark stripes and a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stegodon
''Stegodon'' ("roofed tooth" from the Ancient Greek words , , 'to cover', + , , 'tooth' because of the distinctive ridges on the animal's molars) is an extinct genus of proboscidean, related to elephants. It was originally assigned to the family Elephantidae along with modern elephants but is now placed in the extinct family Stegodontidae. Like elephants, ''Stegodon'' had teeth with plate-like lophs that are different from those of more primitive proboscideans like gomphotheres and mastodons. The oldest fossils of the genus are found in Late Miocene strata in Asia, likely originating from the more archaic ''Stegolophodon,'' shortly afterwards migrating into Africa. While the genus became extinct in Africa during the Pliocene, ''Stegodon'' remained widespread in Asia until the end of the Pleistocene. Morphology Size Some species of ''Stegodon'' were amongst the largest proboscideans. ''S. zdanskyi'' is known from an old male (50-plus years old) from the Yellow River that is tall ...

Canidae
Canidae (; from Latin, ''canis'', "dog") is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade. A member of this family is also called a canid (). There are three subfamilies found within the canid family, which are the extinct Borophaginae and Hesperocyoninae, and the extant Caninae. The Caninae are known as canines, and include domestic dogs, wolves, coyotes, foxes, jackals and other extant and extinct species. Canids are found on all continents except Antarctica, having arrived independently or accompanied human beings over extended periods of time. Canids vary in size from the gray wolf to the fennec fox. The body forms of canids are similar, typically having long muzzles, upright ears, teeth adapted for cracking bones and slicing flesh, long legs, and bushy tails. They are mostly social animals, living together in family units or small groups and behaving cooperatively. Typically, only the dominant pair in a group bree ...
