  Batylykh Formation (Russia) | |
The Batylykh Formation is a geological formation in Yakutia, Russia. It is of an uncertain Early Cretaceous age, probably dating between the Berriasian and the Barremian. It is the oldest unit of the 1,500 metres (4,900 ft) thick Sangar Series within the Vilyuy syneclise. The mudstones, sandstones and shales of the formation were deposited in a fluvial to lacustrine environment.
