Ribadesella, Barrios Fm, "El Fabar Beds” (Cambrian of Spain)

Where: Spain (43.5° N, 5.1° W: paleocoordinates 60.1° S, 99.0° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Protopeltura praecursor trilobite zone, La Matosa Member (Barrios Formation), Furongian (497.0 - 485.4 Ma)

• According to Albani et al. (2006), the El Fabar microflora might correspond to the lower part of Microflora RA5 from eastern Newfoundland (Parsons & Anderson 2000), which can be correlated with the upper part of Microflora A4 of Martin in Martin & Dean (1988) from the same area. The latter is placed in the

•Protopeltura praecursor trilobite biozone recognized in Avalonian Canada, Britain and Scandinavia, that has been considered either of late Jiangshanian age by Westrop et al. (2011) or as of earliest Cambrian Stage 10 age by

•Rushton et al.

Environment/lithology: shallow subtidal; gray shale

• one metre of fine grey and micaceous shale in the lower half of the “El Fabar Beds”.

Size classes: mesofossils, microfossils

Preservation: trace
