El Pinetell, Montblanc district (Triassic of Spain)

Where: Spain (41.3° N, 1.1° E: paleocoordinates 5.9° N, 14.4° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Pedra d'Alcover Formation, Longobardian (242.0 - 235.0 Ma)

• Upper Ladinian, Alcover Unit

• bed-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; lithified dolomite

• Clearly marine laminated dolomicrite. The uniformity of the lamination, its fine grain size, the absence of structures such as ripples, and presence of euhedral halite crystals, suggest a very calm and hypersaline depositional environment. Also, these authors suggested the following depositional sequence: (1) the Alcover unit was deposited in an anoxic basin, affected by sporadic currents (of density?) and evolving to hypersaline conditions; (2) it settled among preexisting depressions due to former bioherms; (3) the deposit was caused by decanting from muddy suspensions.

Size class: macrofossils
