Abstract

The article describes the first find of a bird from the Paleogene of Siberia. A fragment of tibiotarsus from the Eocene Tavda Formation of the Tyumen Region (Western Siberia) is assigned to Procellariiformes. The bird is morphologically closer to Procellariidae, but comparable in size to albatrosses (Diomedeidae) and is assumed to represent the stem members of the family. The find indicated for the first time that either stem albatrosses or similar large Procellariiformes could have had a worldwide distribution as early as the Eocene.

西伯利亚西部始新世的一种大型海鸟（有孔虫类：Procellariiformes）。

文章描述了在西伯利亚古近纪首次发现的鸟类。从秋明地区（西西伯利亚西部）始新世塔夫达地层中发现的一块胫跗骨碎片被归入鸨形目。这种鸟在形态上与信天翁科（Procellariidae）较为接近，但体型与信天翁科（Diomedeidae）相当，因此被认为是信天翁科干系成员的代表。这一发现首次表明，早在始新世，茎信天翁或类似的大型信天翁类就可能分布于世界各地。
