Shakh Shakh (PIN/IZN) (Cretaceous to of Kazakhstan)

Also known as Shakh-Shakh

Where: Qyzylorda, Kazakhstan (45.6° N, 64.4° E: paleocoordinates 38.3° N, 57.8° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Bostobe Formation, Santonian to Santonian (86.3 - 70.6 Ma)

• bed-level stratigraphic resolution

Environment/lithology: estuary or bay; red claystone and red sandstone

• the abundance and diversity of chondrichthyan fish suggests a marine influence

• The fossil-bearing level belongs to the Senonian Bostobe Formation, which is composed of alternating predominantly red clays and sandstones (Sidorenko, 1972; Kordikova et al., 2001). The main fossiliferous bed is red clay in the middle of the section (Rozhdestvensky, 1964).

Size classes: macrofossils, mesofossils

Collected by A. Averianov in 2012

Collection methods: bulk, surface (float), surface (in situ),

• Screen washing of 402kg of matrix
