Adrar-n-Ouglagal tracksite (Jurassic of Morocco)

Where: Ouarzazate, Morocco (31.3° N, 7.1° W: paleocoordinates 24.6° N, 6.8° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Imi-n-Ifri Formation, Sinemurian (196.5 - 189.6 Ma)

• upper third of formation

• bed-level stratigraphic resolution

Environment/lithology: paralic; limestone and dolomite

• shallow depth of water, low-energy, marine or lagoonal, supratidal
• "The footprints appear on the surface of a vast limestone...on a surface of between 8 and 9000 square meters." Dolomite elsewhere in formation. Described as "marls and dolomites (150 m) passing to limestones and dolomitic limestones (150 m) of the Lower Lias (Sinemurian); the summit of this carbonate sequence is marked by a bench of yellow 'cargneule' capped by a hard-ground."

Size class: macrofossils

Preservation: trace
