Where: Paraguay (25.0° S, 58.0° W: paleocoordinates 47.2° S, 140.3° W)
• coordinate estimated from map
• local area-level geographic resolution
When: Salopochtina monterrosae other zone, Cariy Sandstone Formation, Telychian to Telychian (438.5 - 430.5 Ma)
• Unit 2 (informal) (from bottom). Harrington provisionally places this formation as Llandovery. Grahn and Gutierrez (2001, PBDB ref. 7139), on the basis of chitinizoan zonation, conclude that it spans Telychian to Sheinwoodian ages. Unit 2
• member-level stratigraphic resolution
Environment/lithology: marine; micaceous, yellow sandstone and gray claystone
Size class: macrofossils
Collection methods: I have combined lists from Cerro Aparipi and Cerro Pero.
