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.^[1][2] The flora of the formation is relictual, containing some of the youngest remains of the extinct plant orders Bennettitales and Czekanowskiales.^[3][4]
