Novospasskoye Village, well 156, depth 58 m (PIN Collection 2023) (Jurassic of Russian Federation)

Where: Russian Federation (51.3° N, 108.6° E: paleocoordinates 55.9° N, 109.3° E)

• coordinate based on nearby landmark

• small collection-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

• bed-level stratigraphic resolution

Environment/lithology: lacustrine - small; 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 class: macrofossils

Preservation: mold/impression

Reposited in the PIN
