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.[2]
