Paleoazolla type locality, Cerro Buitre (Cretaceous of Argentina)
Also known as Paleoazolla type locality, Cerro Buitre, NE Chubut Province
Where: Chubut, Argentina (42.5° S, 66.5° W: paleocoordinates 44.9° S, 54.8° W)
• coordinate based on political unit
• outcrop-level geographic resolution
When: La Colonia Formation, Maastrichtian (72.1 - 66.0 Ma)
• La Colonia Formation is located between the Telsen and Sierra Rosada (Puesto Pintihueque) regions along the plateau border, in Chubut Province, Argentina.
•
•La Colonia Fm = Maastrichtian (Clyde et al. 2021)
• bed-level stratigraphic resolution
Environment/lithology: terrestrial; lithology not reported
• Argillaceous portions of the lower and middle levels of the formation are continental, probably lacustrine deposits, reflecting periodic wet and dry intervals (Ardolino, and Franchi, 1996). Fossil plants and the remains of the dinosaur Carnotaurus sastrei were found in the wet units. The upper part of the sequence changes gradually to a marginal and shallow marine environment with an important assemblage of micro- and megafauna.
Size class: microfossils
Preservation: original sporopollenin
Collection methods: surface (in situ), chemical,
• Located at Museo Paleontologico Egidio Feruglio
