Chapter 2. Material and Localities

This chapter describes the main localities of fossil Eurasian coturnicines (Aves: Phasianidae: Coturnicini). The age and fauna of the Sansan locality (Middle Miocene; France) and Tagay locality (latest Early–early Middle Miocene; East Siberia), which yielded the oldest finds of coturnicines in Eurasia, are discussed in more detail. The geological description of the Sharga locality (Middle Miocene; Mongolia), Hyargas-Nuur 2 locality (Khirgiz-Nur; Miocene–Pleistocene; Mongolia), and Chono-Harayah 1 and 2 localities (Chono-Khariakh; Pliocene; Mongolia) are given as of 2010.
