Where: Wales, United Kingdom (52.1° N, 3.5° W: paleocoordinates 36.6° S, 16.8° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: acinaces - cyphus zone, shelly facies Member, Rhuddanian (443.4 - 440.8 Ma)

• No formation name. [Late Rhuddanian entered because of the listed biozone.]

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified, sandy siltstone

• "...consists of detrital sediments, but mainly mudstones and sandstones, and with a fauna predominantly of brachiopods."

Collection methods: bulk,

• Two samples were grabbed, "A" and "A1" which, presumably, were different but are undistinguished in their collection notes. Abundances b/w the two were given, they are in the comments field.
