Shakh Shakh 2C (Cretaceous to of Kazakhstan)

Where: Qyzylorda, Kazakhstan (45.9° N, 64.7° E: paleocoordinates 38.7° N, 58.0° E)

• coordinate estimated from map

• outcrop-level geographic resolution

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

• Bostobe Formation (Late Cretaceous, Santonian–?Campanian).

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; silty claystone

• Once wet, the clay and silt quickly disintegrated, leaving about 10% of the original weight composed mostly of small rock fragments and rare bones

Size class: mesofossils

Collected by G. Dyke and D.V. Malakhov in 2007; reposited in the PIN

Collection methods: bulk, sieve,

• The matrix from Shakh Shakh 2C was wet sieved through a 1 mm mesh screen. Once wet, the clay and silt quickly disintegrated, leaving about 10% of the original weight composed mostly of small rock fragments and rare bones. The concentrate was picked in Almaty in 2007
