Also known as Upper Neseuretus tristani Shale/Los Rasos Sandstone Fm., Toledo Mountains, Spain

Where: Ciudad Real, Spain (39.0° N, 4.0° W: paleocoordinates 75.3° S, 79.1° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Glyptograptus teretiusculus graptolite zone, Navas de Estena Formation, Dobrotivian to Dobrotivian (459.0 - 449.5 Ma)

• Dobrotivian Stage, but possibly above G. teretiusculus zone: therefore possibly Lower Caradoc age. Regarding both Neseuretus tristani Shale and Los Rasos Sandstone: not sure if each facies given own formation name, or if these are synonymous

•

•PJW: Los Rasos is a member in the Lower Dobrotivian portion of the Navas de Estena/Navatrasierra formation. This probably is above that. Dobrotivian probably extends into lower Sandbian.

• formation-level stratigraphic resolution

Environment/lithology: offshore; lithified, concretionary, ferruginous, shelly/skeletal, argillaceous, calcareous shale and lithified sandstone

Size classes: macrofossils, mesofossils

Preservation: mold/impression
