Rio Maior, RM.52 (Pliocene of Portugal)

Where: Portugal (39.4° N, 9.0° W)

• Paleocoordinates: 38.8° N, 8.3° W (Wright 2013)

• coordinate estimated from map

• hand sample-level geographic resolution

When: Pliocene (5.3 - 2.6 Ma)

Environment/lithology: marine; diatomite and lignite

• A sequence of lacustrine diatomites and lignites. RM.52 was sampled in diatomite.

Size class: microfossils

Preservation: original sporopollenin
