Panthera gombaszoegensis georgica

Panthera gombaszoegensis georgica

Panthera onca georgica ssp

 

Order: Carnivora

Family: Felidae

Genus: Panthera

Species: P. onca

Dimensions: length - 1,9 m, height - 75 сm, weight - 35-120 kg

Temporal range: during the Early Pleistocene in Eurasia (Republic of Georgia, dated to about 1.77 Myr)

 

Comparative evaluation of fossil remains of the lower dentition of the jaguar, Panthera onca (Linnaeus, 1758) in the light of recent DNA assessment allows a comprehensive phylogeographic interpretation. The speciation process led a jaguar stem population, clearly of African origin, to disperse over Europe during the time of the Olduvai polarity subchron (1.95-1.77 Myr) (Panthera onca toscana). Based on a hemimandible from Dmanisi, Republic of Georgia, dated to about 1.77 Myr, a new taxon Panthera onca georgica ssp. nov. is proposed for the earliest known Asian member of the species. Its generalized, more cutting dentition mediates between the contemporaneous P. onca toscana and the two later sister subspecies, the Eurasian P. onca gombaszoegensis, which is characterized by a specialized cutting and crushing dentition, and the North American P. onca augusta. Placing the tooth differences within geographic coordinates indicates a central Asian evolutionary node between the latter two forms. Transcontinental dispersal probably brought the jaguar to North America during a glacial period between the Jaramillo polarity subchron and the end of the Matuyama magnetochron (0.99-0.78 Myr), to finally reach South America not before the Rancholabrean. Divergent taxonomic concepts for Pleistocene jaguars are discussed: single species P. onca with several subspecies, two species P. gombaszoegensis and P. onca, or three species P. toscana, P. gombaszoegensis and P. onca.

Сейчас с европейскими ягуарами каша. Проще всего назвать и "Гомбасцогскими" и просто поделить на рассы - западную и восточную. И да, они дотопали до Америки.

Великолепный евразийский ягуар! Только, Ром, я не въезжаю тут с географией - ну там Гомбасцог,Дорн-Дюркгейм, Ахалкалаки или Лахути, люди грамотные знают. А причем тут "трансберингийская"? Эта кошара, что дотопала из Гомасцога или Ахалкалаки до Берингии (Чукото-Аляски)?Или она была открыта как вид где-то в "берингийских" регионах близ Берингова пролива? Так это уже субарктические широты! Просвети неразумеющего...
