Ust-Baley Locality (Czekanowski collection) (Jurassic of Russian Federation)

Also known as Ust-Balei

Where: Irkutsk, Russian Federation (54.2° N, 100.3° E: paleocoordinates 61.8° N, 99.4° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Ust' -Baleyskaya Member (Cheremkhovskaya Formation), Toarcian (182.7 - 174.1 Ma)

Environment/lithology: lacustrine - small; lithology not reported

• The Ust'-Baley palaeocenosis is a well-described Mesozoic "hypotrophic" lake (Zherikhin and Kalugina 1985), of type "B" according to Sinitshenkova and Zherikhin (1996). It was a small, shallow, permanent lake in a large river valley (but completely isolated from the river), with a low primary production and high oxygen concentration.

Size classes: macrofossils, mesofossils

Preservation: mold/impression

Collected by A. Czekanowski in 1869; reposited in the PIN

• Martynov says specimens are in the Collection of the Geologic Museum Academy of Sciences, now know as PIN
