Abstract
We describe lark (Alaudidae) fossils from the upper Pliocene of the Beregovaya (southern Transbaikalia) and Shaamar (northern Mongolia) localities. The presence of 4 extinct forms in these localities is established, including the new fossil horned lark Eremophila orkhonensis (Zelenkov et Kurochkin, 2012), comb. nov. This is the oldest member of Eremophila in the fossil record, indicating a possible Central Asian origin of the genus. Two other larks Alaudala aff. A. rufescens and Calandrella aff. C. brachydactyla also probably represent extinct forms. The paper describes in detail the osteology of larks and compares it with other passerines in its size class. The evolutionary history of Eremophila is discussed, and the environmental preferences of larks and their relationship to the late Pliocene landscapes of Central Asia are considered.
