6*. Pantipampa, Iruya area ( of Argentina)

Where: Argentina (22.8° S, 65.2° W: paleocoordinates 45.5° S, 128.5° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Kainella meridionalis trilobite zone, Santa Rosita Formation, Tremadoc (486.5 - 477.7 Ma)

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified, fine-grained, gray, green, calcareous sandstone

• "Dark gray to greenish gray, fine to very fine sandstone and calcareous sandstone beds containing bioclastic concentrations characterize Facies 3. Bioclastic concentrations consist mainly of fragmented brachiopods and trilobites, and generally appear at the bases of the calcareous sandstone beds, constituting lenses and layers up to 4 cm thick. Occasionally, concentrations occur at the tops of the sandstone beds. These beds were sampled for conodonts..."

Size class: mesofossils

Collection methods: JA: marked by Novack-Gottshall without explanation as omitting some genera, some macrofossils, some microfossils, and species names, but apparently complete
