The Moskvoretskaya Formation is a
Middle Jurassic (
Bathonian
In the geologic timescale the Bathonian is an age and stage of the Middle Jurassic. It lasted from approximately 168.3 Ma to around 166.1 Ma (million years ago). The Bathonian Age succeeds the Bajocian Age and precedes the Callovian Age.

. It consists of continental claystones, siltstones and sandstones deposited in
karstified segments of underlying Middle Carboniferous limestone, that would have formed underground
aquifer
An aquifer is an underground layer of water-bearing, permeable rock, rock fractures, or unconsolidated materials ( gravel, sand, or silt). Groundwater from aquifers can be extracted using a water well. Aquifers vary greatly in their characteris ...

The formation is divided up into two members, the lower consists of dark clays to silts and is highly
fossiliferous
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved ...

[Pashschenko et al., 2018]
The remains of indeterminate tetanuran dinosaurs are known from the formation. As are fossil flora, fish and abundant remains of the turtle ''
Heckerochelys romani'',
[Sukhanov, 2006] and various other fossils.
