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

Lycaon (genus)
''Lycaon'' is a genus of canid which includes the African wild dog (''Lycaon pictus'') and the extinct '' Lycaon sekowei''. Taxonomy This hypercarnivorous and highly cursorial genus is distinguished by accessory cusps on the premolars. It branched from the wolflike canids lineage during the Plio-Pleistocene. Since then, ''Lycaon'' has become lighter and tetradactyl, but has remained hypercarnivorous. ''Lycaon sekowei'' is known from the Pliocene and Pleistocene of South Africa and was less cursorial. Some researchers consider the extinct ''Canis'' subgenus ''Xenocyon'' as ancestral to both ''Lycaon'' and ''Cuon''. Other researchers propose that the extinct '' Canis (Xenocyon) falconeri'' and '' Canis (Xenocyon) lycaonoides'' should be classified under genus ''Lycaon'', to give the descent of 3 chronospecies: ''L. falconeri'' in the Late Pliocene of Eurasia → ''L. lycaonoides'' in the Early Pleistocene and the beginning of the Middle Pleistocene The Chibanian, widely kno ...

Canis Antonii
The evolution of the wolf occurred over a geologic time scale of at least 300 thousand years. The grey wolf ''Canis lupus'' is a highly adaptable species that is able to exist in a range of environments and which possesses a wide distribution across the Holarctic. Studies of modern grey wolves have identified distinct sub-populations that live in close proximity to each other. This variation in sub-populations is closely linked to differences in habitat – precipitation, temperature, vegetation, and prey specialization – which affect cranio-dental plasticity. The archaeological and paleontological records show grey wolf continuous presence for at least the last 300,000 years. This continuous presence contrasts with genomic analyses, which suggest that all modern wolves and dogs descend from a common ancestral wolf population that existed as recently as 20,000 years ago. These analyses indicate a population bottleneck, followed by a rapid radiation from an ancestral population ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 oth ...

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 wo ...

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 ...

Arezzo
Arezzo ( , , ) , also ; ett, 𐌀𐌓𐌉𐌕𐌉𐌌, Aritim. is a city and '' comune'' in Italy and the capital of the province of the same name located in Tuscany. Arezzo is about southeast of Florence at an elevation of above sea level. As of 2022, the population was about 97,000. Known as the city of gold and of the high fashion, Arezzo was home to artists and poets such as Giorgio Vasari, Guido of Arezzo and Guittone d'Arezzo and in its province to Renaissance artist Michelangelo. In the artistic field, the city is famous for the frescoes by Piero della Francesca inside the Basilica of San Francesco, and the crucifix by Cimabue inside the Basilica of San Domenico. The city is also known for the important Giostra del Saracino, a game of chivalry that dates back to the Middle Ages. History Described by Livy as one of the ''Capita Etruriae'' (Etruscan capitals), Arezzo (''Aritim'' in Etruscan) is believed to have been one of the twelve most important Etruscan ...
