Where: Wales, United Kingdom (51.8° N, 5.0° W)
• Paleocoordinates: 32.2° S, 67.7° W (Wright 2013)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: atavus - acinaces zone, Rhuddanian (443.4 - 440.8 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." 120 mm, 8.2 kg.
