Where: Buryatia, Russian Federation (51.8° 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)

• 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.

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - small; lithified siliciclastic sediments

Size classes: macrofossils, mesofossils

Preservation: adpression
