Eurypterid-Associated Biota of the Patrick Burn Fm., Lesmahagow (Siltstones) (Silurian to of the United Kingdom)

Where: Scotland, United Kingdom (55.7° N, 3.9° W: paleocoordinates 16.4° S, 20.6° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Patrick Burn Formation (Priesthill Group), Llandovery to Llandovery (443.4 - 427.4 Ma)

• Jamoytius horizon.

• member-level stratigraphic resolution

Environment/lithology: marginal marine; siltstone and siliciclastic

• "Probably BA 1 or nonmarine for the vertebrates-eurypterid bed, and BA 2 or 3 for the marine invertebrates that occur considerably lower in the formation; Rolfe and Beckett (1984) suggest deep (>100 m) basin."
• "Laminated siltstones, interbedded with turbidites."

Collection methods: "The marine shells [which are in the turbidites] are not in the same beds as the vertebrates or the eurypterids [which are in the laminated siltstones]."
