Valle Laoz - Bed No. 32 [Gordon Mbr, Nocedo Fm] (Devonian of Spain)

Where: Spain (42.8° N, 5.2° W: paleocoordinates 30.4° S, 17.0° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Gordon Member (Nocedo Formation), Frasnian (382.7 - 372.2 Ma)

• STRATIGRAPHIC RELATIONS: According to the regional geology north of La Ercina, it appears most plausible that the host rocks belong to the Gordon Member of the Nocedo Formation which crops out 3 km north of La Ercina. The Nocedo Formation was described by Evers (1968) and van Loevezijn (1982, 1986a, b). AGE: STRATIGRAPHIC POSITION: All of the specimens are said to come from ‘Schicht N 32’, that is, bed N 32, of a section not known today, as we have no information about the outcrops and sections near La Ercina studied by Kegel during his field studies in 1927.

• bed-level stratigraphic resolution

Environment/lithology: lithified, medium-grained, coarse sandstone

• SPECIFIC LITHOLOGY: The host sedimentary rock is a medium- to coarse-grained, pale reddish to pale brownish sandstone. All the fossils are preserved as internal or external moulds. LITHIFICATION: Lithified, on the basis of facies description and figured specimens.

Size class: macrofossils

Preservation: cast, mold/impression

Collected by Kegel in 1927; reposited in the NMB

Collection methods: surface (in situ),

• COLLECTOR: W. Kegel, 1927. REPOSITORY: Naturkunde Museum Berlin.
