Novaya Bryan' (PIN collection 1569) (Jurassic of Russian Federation)

Where: Buryatia, Russian Federation (51.7° N, 108.3° E: paleocoordinates 56.3° N, 108.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Ichetuy Formation, Oxfordian (163.5 - 157.3 Ma)

• Formation also translated Ichetyua. Insect workers often assign a late Early Jurassic-early Middle Jurassic (or Toarcian-Aalenian) age but radiometric dating of Ichituy Fm volcanics gives ages of 159-156 Ma.

Environment/lithology: lacustrine - small; lithified siliciclastic sediments

• Novospasskoe was a typical Mesozoic lake of type "A" according to Sinitshenkova and Zherikhin (1996), a deep mountain lake formed when a river valley was naturally dammed. It was a cold oligotrophic water body with low primary production and ample oxygen.

Size classes: macrofossils, mesofossils

Preservation: mold/impression
