Altynshokysu (bone bed I) (Oligocene of Kazakhstan)

Also known as Altyn Schokysu; bone bed 1

Where: Aktyubinsk, Kazakhstan (50.3° N, 57.2° E: paleocoordinates 51.0° N, 54.6° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Aral Formation, Late/Upper Oligocene (28.4 - 23.0 Ma)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; pebbly, gray, blue, sandy siltstone and claystone

• Clayey silts, light bluish gray, sand-rich in an upper portion enclosing the bone-bearing lenses and intercalations. The main bone-bearing level is at the top of the bed. Fragments of bones are usually mixed with small pebbles and gravels (1 m).

Size classes: macrofossils, mesofossils
