Where: Chubut, Argentina (42.7° S, 69.7° W: paleocoordinates 43.2° S, 65.5° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Collón Cura Formation, Langhian to Langhian (16.0 - 11.6 Ma)
• Los Yeguarizos has an area of ∽0.5 km2 and it is constituted by ∽35 m thick of volcaniclastic sediments
•Fossils collected in two different levels in the base of the section, but as the authors do not clearly separate the specimens per level, all the occurrences are grouped into a single collection point for the moment.
Environment/lithology: delta plain; sandstone and siltstone
Size classes: macrofossils, mesofossils
