Abstract

Bird bones from the Late Pleistocene (31–24 kyr) Ikhine-2 site (Central Yakutia), one of the key Upper Paleolithic sites in northeastern Siberia, have first been studied. This is the northernmost and the oldest bird association in the Pleistocene of Eastern Siberia. Among the bone materials available, the coracoids of the extinct Dyuktai goose (Anser djuktaiensis) and the hooded crane (Grus monacha) are of particular interest. Dyuktai goose is a large representative of the mammoth fauna, originally described from younger deposits (12–13 kyr) in southeastern Yakutia. This is the second find of this species in Russia, which significantly expands our understanding of the geography and time of its distribution. The hooded crane, a rare modern species with a limited habitat area, has first been found in paleontological record. This find indicates the northern distribution of this species during the Late Pleistocene Karginian interstadial. Bones of Anas crecca and Larus canus have also been found at the site.

来自中雅库特更新世的 Dyuktai 鹅 (Anser djuktaiensis) 和白头鹤 (Grus monacha)

摘要

来自晚更新世（31-24 kyr）Ikhine-2 遗址（雅库特中部）的鸟类骨骼是西伯利亚东北部上旧石器时代的主要遗址之一，已被首次研究。这是东西伯利亚更新世最北端和最古老的鸟类协会。在可用的骨骼材料中，已灭绝的 Dyuktai 鹅 ( Anser djuktaiensis ) 和白头鹤 ( Grus monacha ) 的喙骨) 特别感兴趣。Dyuktai鹅是猛犸象动物群的主要代表，最初描述于雅库特东南部较年轻的沉积物（12-13 kyr）。这是该物种在俄罗斯的第二次发现，极大地扩展了我们对其分布的地理和时间的了解。头巾鹤是一种栖息地有限的现代稀有物种，首次在古生物学记录中被发现。这一发现表明该物种在晚更新世卡吉尼亚间期的北部分布。在现场还发现了Anas crecca和Larus canus的骨头。
