Boca do Chapim / Praia do Areia do Mastro tracksite (Cretaceous of Portugal)

Where: Lisboa, Portugal (38.4° N, 9.2° W: paleocoordinates 31.8° N, 1.3° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Areia do Mastro Formation, Early/Lower Barremian (130.0 - 125.5 Ma)
