PBDB Collection

Kempendyay River (PIN collection 923) (Cretaceous to of Russian Federation)

Also known as Teete

Where: Yakutiya, Russian Federation (62.2° N, 118.6° E: paleocoordinates 66.2° N, 111.7° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Khaya Formation (Sangara Group), Berriasian to Berriasian (145.0 - 125.0 Ma)

• Age given as "earliest Cretaceous or Latest Jurassic" but "latest Jurassic" in Shcherbakov 2008. Berriasian-Barremian, or the lower part of the Lower Cretaceous (Averianov et al., 2012).

• bed-level stratigraphic resolution

Environment/lithology: pond; lithified, lenticular siltstone and poorly lithified, fine-grained, medium sandstone

• "The insect remains are fragmentary due to the alluvial genesis of the sediments." Mostovski, 2000. Insect fossils found (mostly isolated wings) were probably deposited under conditions of a former riverbed in a small river backwater or oxbow lake (Sinitshenkova, 1992). Lena-Vilyuy basin in Preverkhoyansk foreland basin.

• "More than a thousand insect remains have been found here in the siltstone lenses that occurred among the poorly cemented obliquely laminated fine- and middle-grained sandstones." Mostovski, 2000

Size classes: macrofossils, mesofossils

Preservation: mold/impression

Reposited in the PIN
