Also known as Eurypterid-Associated Biota of the Mocktree Shale, Leintwardine

Where: England, United Kingdom (52.4° N, 2.9° W: paleocoordinates 25.8° S, 12.5° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Leintwardine Formation, Ludfordian (425.6 - 423.0 Ma)

• Lower Leintwardine (=Mocktree Shale). Age given as Ludlow. Ludfordian assignment based on Cherns (1999, PBDB ref. 6652).

• formation-level stratigraphic resolution

Environment/lithology: marine; micaceous, gray, green siltstone

• BA 3, based on the brachiopods
• "Greenish-gray, finely micaceous, fine-grained siltstone"

Collection methods: Brachiopods overlap with collections 479,533,23109,23110,23111,23113,23184, 26300, and 26301, but none of these collections includes the eurypterids.
