  Kakanaut Formation (Russia) | |
The Kakanaut Formation is a geological formation in Siberia, whose strata date back to the Late Cretaceous (Maastrichtian). Dinosaur remains are among the fossils that have been recovered from the formation. The flora of the formation is relictual, containing some of the youngest remains of the extinct plant orders Bennettitales and Czekanowskiales.
