Canis Mosbachensis
''Canis mosbachensis'', sometimes known as the Mosbach wolf, is an extinct small wolf that once inhabited Eurasia from the Middle Pleistocene era to the Late Pleistocene. It is widely accepted as the ancestor of ''Canis lupus'', the grey wolf. Taxonomy The holotype of the Mosbach wolf ''Canis mosbachensis'' Soergel, 1925 was found in Jockgrim, Germany. In 2010, a study found that the diversity of the ''Canis'' group decreased by the end of the Early Pleistocene to Middle Pleistocene and was limited in Eurasia to two types of wolves. These were the small wolves of the ''C. mosbachensis–C. variabilis'' group that were a comparable size to the extant Indian wolf ''(Canis lupus pallipes)'', and the large hypercarnivorous ''Canis (Xenocyon) lycaonoides'' that was comparable in size to extant northern grey wolves. The Mosbach wolf occurred in time between ''C. etruscus'' in the Early Pleistocene and the modern ''C. lupus''. The Mosbach wolf was smaller than most North American wolf ...

Middle Pleistocene
The Chibanian, widely known by its previous designation of Middle Pleistocene, is an age in the international geologic timescale or a stage in chronostratigraphy, being a division of the Pleistocene Epoch within the ongoing Quaternary Period. The Chibanian name was officially ratified in January 2020. It is currently estimated to span the time between 0.770 Ma (770,000 years ago) and 0.126 Ma (126,000 years ago), also expressed as 770–126 ka. It includes the transition in palaeoanthropology from the Lower to the Middle Palaeolithic over 300 ka. The Chibanian is preceded by the Calabrian and succeeded by the proposed Tarantian. The beginning of the Chibanian is the Brunhes–Matuyama reversal, when the Earth's magnetic field last underwent reversal. It ends with the onset of the Eemian interglacial period (Marine Isotope Stage 5). The term Middle Pleistocene was in use as a provisional or "quasi-formal" designation by the International Union of Geological Sciences (IUGS). W ...

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Wolf Cranium Labelled
The wolf (''Canis lupus''; : wolves), also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. More than thirty subspecies of ''Canis lupus'' have been recognized, and gray wolves, as popularly understood, comprise wild subspecies. The wolf is the largest extant member of the family Canidae. It is also distinguished from other ''Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The banded fur of a wolf is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most specialized for cooperative game hunting as demonstrated by its physical adaptations to tackling large prey, its more social nature, and its highly advanced ...

Peking Man
Peking Man (''Homo erectus pekinensis'') is a subspecies of ''Homo erectus, H. erectus'' which inhabited the Zhoukoudian Cave of northern China during the Middle Pleistocene. The first fossil, a tooth, was discovered in 1921, and the Zhoukoudian Cave has since then become the most productive ''H. erectus'' site in the world. Peking Man was instrumental in the foundation of Chinese anthropology, and fostered an important dialogue between Western and Eastern science for decades to come. The fossils became the centre of anthropological discussion, and were classified as a direct human ancestor, propping up the Out of Asia hypothesis that humans evolved in Asia. Peking Man also played a vital role in the restructuring of the Chinese identity following the Chinese Communist Revolution, and was intensively communicated to working class and peasant communities to introduce them to Marxism and science (overturning deeply-rooted superstitions and Chinese creation myths, creation myths). ...

Canis
''Canis'' is a genus of the Caninae which includes multiple extant species, such as wolves, dogs, coyotes, and golden jackals. Species of this genus are distinguished by their moderate to large size, their massive, well-developed skulls and dentition, long legs, and comparatively short ears and tails.Heptner, V. G.; Naumov, N. P. (1998). ''Mammals of the Soviet Union'' Vol.II Part 1a, SIRENIA AND CARNIVORA (Sea Cows, Wolves and Bears). Science Publishers, Inc. USA. pp. 124–129. . Taxonomy The genus ''Canis'' (Carl Linnaeus, 1758) was published in the 10th edition of Systema Naturae and included the dog-like carnivores: the domestic dog, wolves, coyotes and jackals. All species within ''Canis'' are phylogenetically closely related with 78 chromosomes and can potentially interbreed. In 1926, the International Commission on Zoological Nomenclature (ICZN) in Opinion 91 included Genus ''Canis'' on its ''Official Lists and Indexes of Names in Zoology''.

Open Nomenclature
Open nomenclature is a vocabulary of partly informal terms and signs in which a taxonomist may express remarks about their own material. This is in contrast to synonymy lists, in which a taxonomist may express remarks on the work of others. Commonly such remarks take the form of abbreviated taxonomic expressions in biological classification. Usage of open nomenclature There are no strict conventions in open nomenclature concerning which expressions to use or where to place them in the Latin name of a species or other taxon, and this may lead to difficulties of interpretation. However, the most significant unsettled issues concern the way that their meanings are to be interpreted. The International Code of Zoological Nomenclature (ICZN) makes no reference to open nomenclature, leaving its use and meaning open for interpretation by taxonomists. The following are examples of commonly used shorthand in open nomenclature: *Sp. (pl. spp.; short for "species") indicates potentially new ...

Canis Arnensis
''Canis arnensis'', the Arno River dog, is an extinct species of canine that was endemic to Mediterranean Europe during the Early Pleistocene. The Arno River dog has been described as a small jackal-like dog. Its anatomy and morphology relate it more to the modern golden jackal (''Canis aureus'') than to the larger Etruscan wolf of that time. It is probably the ancestor of modern jackals. Taxonomy The fossil record for ancient vertebrates is composed of rarely occurring fragments from which it is often impossible to obtain genetic material. Researchers are limited to morphologic analysis, but it is difficult to estimate the intraspecies and interspecies variations and relationships that existed between specimens across time and place. Some observations are debated by researchers who do not always agree and hypotheses that are supported by some authors are challenged by others. Several species of Caninae from the Pleistocene of Europe have been described. Most of their system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canis Etruscus
''Canis etruscus'', the Etruscan wolf, is an extinct species of canine that was endemic to Mediterranean Europe during the Early Pleistocene. The Etruscan wolf has been described as a small wolf-like dog. The Etruscan wolf has been accepted as the ancestor of '' C. mosbachensis'', that is the ancestor of the grey wolf (''C. lupus''), for a long time. Recent research has suggested that ''C. borjgali'' from Dmanisi has to be considered the ancestor of '' C. mosbachensis''.
