Ust' Kolba quarry (Cretaceous to of Russian Federation)

Also known as LMCCE 001, UKo, Ust'-Kolba

Where: Kemerovo, Russian Federation (55.9° N, 88.3° E: paleocoordinates 54.2° N, 84.9° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Ilek Formation, Barremian to Barremian (129.4 - 113.0 Ma)

• Age of Ilek Formation is poorly constrained but is currently believed to be Barremian-Aptian (see Averianov et al. 2018). The fossiliferous layer at Shestakovo 1 locality was dated to Aptian (Bugadeva et al. 2017). The overlying Kiya Formation has been assigned Albian age based on plant remains (Golovneva and Shchepetov 2010).

• bed-level stratigraphic resolution

Environment/lithology: fluvial; green, yellow sandstone

• yellowish-green assorted sands with an admixture of pebble and gravel, confined mainly to the bottom of cross-bedded layers and lenses. Pebbles and gravel are presented by pellets (up to 0.1 m) of thick clays, silts, and carbonate nodules. Vertebrate fossils (scales, bone fragments, and teeth) are confined mainly to the gravel lenses at the bottom of the visible part of the section. These sediments represented a relatively high energy condition, but the preservation of the fossils, although fragmentary, indicates that they were not reworked.

Size classes: macrofossils, mesofossils

Collected in 1995. 2000–2001, 2014

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