Óbidos, OBI.15 (Pliocene of Portugal)

Where: Portugal (39.4° N, 9.1° W)

• Paleocoordinates: 38.8° N, 8.5° W (Wright 2013)

• coordinate estimated from map

• hand sample-level geographic resolution

When: Pliocene (5.3 - 2.6 Ma)

Environment/lithology: marine; lignite and diatomite

• A sequence of diatomites and lignites. OBI.15 was sampled in lignite, above the diatomite from sample OBI.4 (collection number 232122).

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.
