Kuruksay, Kuruksai-Navrukho (Pliocene of Tajikistan)

Also known as Navrukho, Kuruksai

Where: Tajikistan (38.3° N, 69.7° E: paleocoordinates 38.5° N, 69.5° E)

• coordinate based on nearby landmark

When: Kuruksai suite Formation, Pliocene (5.3 - 2.6 Ma)

• Middle Villafranchian, Late Pliocene, MN17. Below the Olduvai Subchron in the lower part of the Matuyama Chron. At the top of the Kuruksay/Kuruksai suite. There are 4 layers at the site - the three lowest are conglomerates and aleurites belonging to the Kuruksai suite (the bone bed is the second of these layers). The topmost bed is largely loessic clay and belongs to the Kairubak suite.

Environment/lithology: fluvial; siltstone and conglomeratic sandstone

• Fluvial deposits - siltstone, sandstone with interbedded conglomerates, belonging to the Kuruksay suite.

Size classes: macrofossils, mesofossils

Collection methods: Two localities have been excavated - Kuruksai-Navrukho and Kuruksai-Lagernaya. This is probably the faunal list from Navrukho.

•The locality was discovered in 1962.
