Mickleton Tunnel, near Chipping Campden (Jurassic of the United Kingdom)

Where: England, United Kingdom (52.1° N, 1.8° W: paleocoordinates 39.4° N, 7.0° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Charmouth Mudstone Formation, Davoei (189.6 - 183.0 Ma)

• from the Aegoceras capricornis Subzone of the Prodactylioceras davoei Zone

• group of beds-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; lithified shale

• Echinoderms were found at many horizons at interfaces between different lithologies; Simms (1986) interpreted these occurences as obrution deposits, and he suggested periodic smothering resulting from the influx of sand and finer sediments

Size class: macrofossils

Reposited in the BMNH
