Rio Maior, RM.71 (Pliocene of Portugal)

Where: Portugal (39.4° N, 9.0° W: paleocoordinates 39.4° N, 9.3° W)

• 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.71 was sampled in diatomite.

Size class: microfossils

Preservation: original sporopollenin

Collection methods: bulk, chemical, hydrochloric, hydroflouric,

• Standard laboratory processing for palynomorphs with HCl and HF for acid maceration followed by sieving. Final residues were diluted in liquid glycerine and mounted on slides.
