Puesto Fernández - Bororó (Paleocene of Argentina)

Where: Chubut, Argentina (43.7° S, 67.8° W: paleocoordinates 46.2° S, 56.7° W)

When: Lower Member (Bororó Formation), Danian (66.0 - 61.6 Ma)

• This palynological assemblage was yielded by a single 15 cm thick bed.

Environment/lithology: marginal marine; lithified, carbonaceous mudstone

• The Lower Member of the Cerro Bororó Fm unconformably overlies the Late Cretaceous Chubut Group. An alternation of marginal marine strata and near-coast freshwater deposits occur in the sections.

• This palynological assemblage was yielded by a single 15 cm thick bed of carbonaceous mudstone.

Size class: microfossils

Preservation: soft parts, original sporopollenin

Collection methods: chemical, hydrochloric, hydroflouric,

• SEM studies (Phillips XL Serie 30) were done at the Museo “B. Rivadavia.”
