Imi-n-Ifri Formation
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.
Description
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.
