La Tierna Mbr, Torreáboles Fm (Cambrian of Spain)

Where: Spain (37.9° N, 5.6° W: paleocoordinates 49.6° S, 108.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: La Tierna Member (Torreárboles Formation), Nemakit-Daldynian (541.0 - 530.0 Ma)

• STRATIGRAPHIC RELATIONS: From La Tierna Mbr of the Torreáboles Fm, which unconformably overlies a Precambrian volcano-sedimentary complex, and is apparently conformably overlain by the Campoallá series. THICKNESS: From single bedding plane within member. AGE: Cordubvan age, equivalent to the Nemakit-Daldynian plus the Tommorian, as indicated by trace fossils (Fedonkin etl, 1985, Liñán, 1984). STRATIGRAPHIC POSITION: From bedding plane within lower part of the La Tierna Member.

• bed-level stratigraphic resolution

Environment/lithology: foreshore; lithified sandstone and conglomerate

• ENVIRONMENT: Extremely shallow marine environment, in which organisms stranded during a single event.
• SPECIFIC LITHOLOGY: Parallel laminated sandstones and conglomerates. LITHIFICATION: Lithified based on figured specimens.

Size class: macrofossils

Preservation: cast, mold/impression

Collected by Mayoral et al.

Collection methods: surface (in situ),

• COLLECTORS: Observed in the field by authors. REPOSITORY: Type material remains in the field, but replicas of the holotype are found in the MPZ (Museo Paleontologico de la Universidad de Zarafoiza-Gobierno de Aragon). Replica of paratype material is found at the Museo de Geologia de la Univesidad de Sevilla (MGUS)
