The Imi-n-Ifri Formation is a Sinemurian geologic formation outcropping about 6 kilometres (3.7 mi) from Demnate, to the east of Marrakech, Morocco.

Fossil ornithopod tracks have been reported from the formation.

[1] The formation comprises limestones and dolomites deposited in shallow depth of water, low-energy, marine or lagoonal to supratidal environments.

The footprints appear on the surface of a vast limestone on a surface of between 8 and 9,000 square metres (86 and 96,875 sq ft).

The top of the carbonate sequence is marked by a bench of yellow 'cargneule' capped by a hardground.
