Eurypterid-Associated Biota of the Reservoir Beds, Pentland Hills (Silurian of the United Kingdom)

Where: Scotland, United Kingdom (56.0° N, 3.0° W: paleocoordinates 15.0° S, 21.5° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Reservoir Formation, Llandovery (443.4 - 433.4 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marginal marine; mudstone and sandy siltstone

• "Waterston (1979) tentatively interprets this as a marginal marine setting. The described sedimentary features are compatible with, but not diagnostic of, a tidal flat setting. BA 1"
• "Alternating mudstone and sandy siltstone; groove casts and load casts; small cross laminae and convolute lamination in siltstone."
