Cariy Sandstone, Unit 2 (Silurian to of Paraguay)

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 (436.0 - 426.2 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

• "The Cairy Sandstone, which forms the upper part of the Itacuburi Group, conformably overlies the Vargas Pena Shale and is unconformably overlain by upper Paleozoic glacial deposits. The sandstones and intercalated clay-shales were deposited in a marine environment, probably ranging from proximal neritic to sublittoral."
• "Well-bedded, yellow to reddish-brown, fine-grained micaceous sandstones, with intercalations of ligh-gray to whitish clay-shale..."

Size class: macrofossils

Collection methods: I have combined lists from Cerro Aparipi and Cerro Pero.
