Abstract

Remains of Lyrurus partium Kretzoi, 1962 and “Lagopus” atavus Jánossy, 1974 (tribe Tetraonini, family Phasianidae, order Galliformes) are described from the Lower Pleistocene of the Taurida Cave (Crimea); these are the oldest finds of the grouse in Eurasia outside of Central and Eastern Europe (Bulgaria, Hungary, and Poland). The discovery of the primitive black grouse Lyrurus partium indicates that these birds were part of the savanna-like faunal associations of the Northern Black Sea region (along with Otididae and Struthionidae) in the Early Pleistocene. The origin and evolutionary history of the modern Caucasian black grouse T. mlokosiewiczi Taczanowski, 1875 is discussed. The complete tarsometatarsus of “Lagopus” atavus from the Taurida Cave indicates a separate generic status of this poorly studied Plio-Pleistocene form, which is here transferred to the genus Paralyra gen. nov. Therefore, the presence of ptarmigans (genus Lagopus) in the preglacial Plio-Pleistocene faunas of Eastern Europe is not confirmed.

克里米亚早更新世的松鸡（Aves: Phasianidae: Tetraonini）以及 Lagopus atavus 的分类地位

摘要描述了来自陶里达洞穴（克里米亚）下更新统的 Lyrurus partium Kretzoi, 1962 和 "Lagopus" atavus Jánossy, 1974（四齿鸟目，雉科，瘿形目）的遗骸；这是在中欧和东欧（保加利亚、匈牙利和波兰）以外的欧亚大陆发现的最古老的松鸡。原始黑松鸡（Lyrurus partium）的发现表明，在早更新世，这些鸟类是北黑海地区热带稀树草原动物群落的一部分（还有獭科和栗鸡科）。本文讨论了现代高加索黑松鸡（T. mlokosiewiczi Taczanowski, 1875）的起源和进化史。来自陶里达洞穴的 "Lagopus "atavus的完整跗蹠表明，这种研究较少的上新世形态具有独立的属种地位，在此将其归入Paralyra gen.因此，东欧冰期前的上新世动物群中存在侏儒动物（Lagopus 属）的说法没有得到证实。

期刊介绍： Paleontological Journal (Paleontologicheskii zhurnal) is the principal Russian periodical in paleontology. The journal publishes original work on the anatomy, morphology, and taxonomy of fossil organisms, as well as their distribution, ecology, and origin. It also publishes studies on the evolution of organisms, ecosystems, and the biosphere and provides invaluable information on global biostratigraphy with an emphasis on Eastern Europe and Asia.
