Kyrkkuduk II (Cretaceous of Kazakhstan)

Also known as Kyrk-Kuduk, Alymtau; Grey Mesa

Where: OngtÞstik Qazaqstan, Kazakhstan (41.7° N, 68.5° E: paleocoordinates 35.1° N, 62.0° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Dabrazhin Formation, Early/Lower Campanian (83.5 - 70.6 Ma)

• Lower Darbazin subformation = Darbasa = Dabrazhin

• bed-level stratigraphic resolution

Environment/lithology: marginal marine; gray sandstone

• formation includes "terrestrial, brackish water and marine animals" (Averianov 1997), and the preponderance of shark teeth combined with rare terrestrial tetrapods at this site also suggests marginal marine environment
• "gray sandstones and sands"

Size classes: macrofossils, mesofossils

Collected in 1996

Collection methods: bulk, sieve,

• "About 1440 kg" was "dry screened" in 1996 (Averianov 1997)
