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
