Herefordshire Konservat-Lagerstätte (Silurian of the United Kingdom)

Where: United Kingdom (52.1° N, 2.8° W: paleocoordinates 29.4° S, 13.5° W)

• coordinate based on political unit

When: Wenlock (433.4 - 427.4 Ma)

• "2-20 cm concretions (n = 378) that occur in a roughly 1-m-thick volcanic ash-rich deposit"

• bed-level stratigraphic resolution

Environment/lithology: basinal (); concretionary, ferruginous, argillaceous, calcareous carbonate and volcaniclastic

• "relatively deep water west of a shelf area (the Midland Platform)"

• "concretions are dominantly calcitic with some quartz and clay minerals, and accessory iron oxide."

Size class: macrofossils

Preservation: concretion, soft parts, replaced with calcite, replaced with pyrite, replaced with hematite

Collection methods: specimens are in the Oxford University Museum
