Where: England, United Kingdom (52.5° N, 2.1° W: paleocoordinates 28.4° S, 12.9° W)
• coordinate based on political unit
• local area-level geographic resolution
When: Much Wenlock Limestone Formation, Homerian (430.5 - 427.4 Ma)
• formation-level stratigraphic resolution
Environment/lithology: marine; grainstone and lime mudstone
Size class: macrofossils
Collection methods: The Assemblage type is broadly distributed, but it seems fairly clear from the text that the elements listed here are known from the Much Wenlock Limestone.
