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
Size classes: macrofossils, mesofossils
Preservation: mold/impression
