Pedreira do Galinha tracksite (Jurassic to of Portugal)

Also known as Serra D'Aire, Fatima

Where: Santarem, Portugal (39.6° N, 8.6° W: paleocoordinates 32.4° N, 3.1° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Serra de Aire Formation, Late/Upper Bajocian to Late/Upper Bajocian (171.6 - 164.7 Ma)

• near the Bajocian-Bathonian boundary; "The main track level of the Galinha tracksite is a single bedding surface of about 40,000 m2 forming the floor of an abandoned limestone quarry" (Santos et al. 2009)

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, micaceous limestone and pyritic, shelly/skeletal wackestone

• exposed sequence was "deposited in lacustrine, paralic and very shallow, restricted marine conditions"
• "The limestone at this quarry is a well-bedded micrite rich sequence"; the footprint layer is a biomicrite wackestone, with internal "brechhification" and pyrite pigmentation

Size classes: macrofossils, mesofossils

Preservation: mold/impression, trace
