Where: Wales, United Kingdom (51.9° N, 4.3° W: paleocoordinates 35.8° S, 17.4° W)

• coordinate based on political unit

• small collection-level geographic resolution

When: Rhuddanian to Rhuddanian (443.4 - 438.5 Ma)

• Unless a conodont zone was explicitly stated, a Late Rhudd - Late Aeron age was entered because of the statement these beds are all "pre-sedgwickii Zone."

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified mudstone and sandstone

Collection methods: bulk,

• "... a single collection (from bulk material) [was made] from each locality, identifying and recording all fossils encountered during break up of the rock... [sacrificing commoner taxa in continued searching, or preserving rarer specimens and not breaking the rock further]...figures obtained for relative frequencies of the taxa are prob accurate...estimates of volumetric abundance...are prob too low." Sample: 125 mm, 6.1 kg.
