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. [2]
