Fauna s3d-gamma, Badenas Fmn., E. Iberian Chains (Silurian of Spain)

Where: Spain (41.6° N, 0.9° W: paleocoordinates 64.2° S, 48.5° E)

• coordinate based on nearby landmark

When: sandstone-3d Member (Badenas Formation), Ludlow (427.4 - 423.0 Ma)

• bed-level stratigraphic resolution

Environment/lithology: marine; sandstone and sandy shale

• "...general composition is predominantly black fine shales (graptolites very rare), arenaceous shales, sandstones with a few shelly faunas, and some quartzites. Changing sand content distinguishes five members the two youngest of which are considered here. Sandstone member s3d [has] 45 m alternance of fine-grained sandstones and arenaceous shales [sandstones containing shelly faunas] [calcareous ssts in some cases have conodonts]."
