Stratigraphy
Formation:Nocedo Member:Gordon
Local section:Valle Laoz Local bed:32
Local order:bottom to top
Stratigraphic resolution:bed
Stratigraphy comments: 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.
Lithology and environment
Primary lithology:medium,coarse,red or brown lithified sandstone
Lithology description: 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.
Taphonomy
Modes of preservation:cast,mold/impression
Size of fossils:macrofossils
Collection methods and comments
Collection excludes:some genera
Collection methods:surface (in situ),survey of museum collection
Reason for describing collection:taxonomic analysis
Museum repositories:NMB
Collectors:Kegel Collection dates:1927
Collection method comments: COLLECTOR: W. Kegel, 1927. REPOSITORY: Naturkunde Museum Berlin.
Taxonomic list comments:COVERAGE: Limited to bivalves, but probably not an exhaustive sampling of fauna. NOMENCLATURE: Authoritative publication with modern nomenclature and some species-resolution identifications; some taxa remain nomen nudum.
