PBDB Collection

Salopina Comm., Leintwardine Grp., Wales and Welsh Borderland (Silurian of the United Kingdom)

Where: England, United Kingdom (52.0° N, 3.0° W: paleocoordinates 26.2° S, 12.5° W)

• basin-level geographic resolution

When: Whitcliffe Group, Ludfordian (425.6 - 423.0 Ma)

• Community mainly from Whitcliffe group but appears earlier along the Towy Anticline at the level of the Upper Elton (mid-Gorstian), in the siltier facies, and also in the top Wenlock.

Environment/lithology: marine; siliciclastic sediments

• "Regarded as the depth equivalent of the Eocoelia Comm. of the Upper Llandovery. A typical BA 2 unit."

• Ref. 6661: [No lithologic description. See geology comments.]

•Ref. 6660: "clastic sediments"

Size class: mesofossils

Collection methods: Based on Calef and Hancock 1974 (ref. 6660). Abundance data are given, but only brachiopods are treated in detail. This is similar to PBDB coll. 523, but that collections are not identical.
