The Moskvoretskaya Formation is a Middle Jurassic (Bathonian stage) geologic formation in the European part of Russia. It consists of continental claystones, siltstones and sandstones deposited in karstified segments of underlying Middle Carboniferous limestone, that would have formed underground aquifers.

The formation is divided up into two members, the lower consists of dark clays to silts and is highly fossiliferous, while the upper member is sandy and lean in fossil content.[1]

The remains of indeterminate tetanuran dinosaurs are known from the formation. As are fossil flora, fish and abundant remains of the turtle Heckerochelys romani,[2] and various other fossils.[3]
