Ishunin G.I. (1989). The Felids family Felidae Gray, 1821.
Abstract: Zoolites of the Felidae family are known from the Upper Eocene Lower Pliocene in Eurasia, Africa, and North America. Two sub-families are know to inhabit the territory of the USSR and adjacent territories: the extinct sabre-toothed Felidae species Machairodontia and now existing Felidae species. In the USSR the extinct Felidae species were found to exist in Upper Miocene, Upper and Middle Pliocene, and Pleistocene. In Eurasia panthers has been know since early Pliocene. Three species were found in Uzbekistan – the extinct cave lion Felidae sd†l…†… (Goldfuss, 1810), and now existing P…nth†a… tigris, P…nth†a… pardus. The ancient finds and modern habitats are briefly described. Genus Uncia is represented by one species snow leopard or irbis. Probably it appeared in later Pliocene or Pleistocene in the mountain of Central Asia. In Uzbekistan, remains of snow leopard were found in the Samarqand region in the layer of Upper Pleistocene or Holocene. Probably it moved into the area in Pleistocene or the period of glacier removal in the Western Tien Shan mountains, Turkestan, Zeravshan, and Hissar ridges.

Warren E.Johnson, E. E. (2006). The Late Miocene Radiation of Modern Felidae: A Genetic Assessment (Stephen J.O'Brien Emma Teeling Agostinho Antunes W. J. M. Jill Pecon-Slattery, Ed.) (Vol. 311). Washington D.C.
Abstract: Modern felid species descend from relatively recent (<11 million years ago) divergence and
speciation events that produced successful predatory carnivores worldwide but that have
confounded taxonomic classifications. A highly resolved molecular phylogeny with divergence dates
for all living cat species, derived from autosomal, X-linked, Y-linked, and mitochondrial gene
segments (22,789 base pairs) and 16 fossil calibrations define eight principal lineages produced
through at least 10 intercontinental migrations facilitated by sea-level fluctuations. A ghost lineage
analysis indicates that available felid fossils underestimate (i.e., unrepresented basal branch
length) first occurrence by an average of 76%, revealing a low representation of felid lineages
in paleontological remains. The phylogenetic performance of distinct gene classes showed that
Y-chromosome segments are appreciably more informative than mitochondrial DNA, X-linked,
or autosomal genes in resolving the rapid Felidae species radiation.
