Where: Tierra del Fuego, Argentina (53.0° S, 68.7° W: paleocoordinates 53.6° S, 62.8° W)
• coordinate estimated from map
• local area-level geographic resolution
When: Cullen Formation, Early/Lower Miocene to Early/Lower Miocene (23.0 - 11.6 Ma)
• The Cullen Formation outcrops on the NE coast of Isla Grande de Tierra del Fuego and its age has been controversial for a long time; a probably early or middle Miocene age was proposed (Zamaloa, 1999).
• formation-level stratigraphic resolution
Environment/lithology: "channel"; paleosol/pedogenic, green, yellow, silty, sandy siltstone and fine-grained, medium, brown sandstone
Size class: microfossils
Preservation: original sporopollenin
Collection methods: chemical,
• 126 samples were collected, 61 of which contained palynomorphs. Standard palynological techniques were used to prepare the samples. Microscopic slides were mounted in glycerine jelly and stained with safranin. Slides and residues are archived in the palynological collection of the Departamento de Ecologia, Genética y Evolución, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, as BAFCB p.m.
