Stowell Park borehole (Lower Freestone, 233-346ft) (Jurassic of the United Kingdom)

Where: Gloucestershire, United Kingdom (51.8° N, 1.9° W: paleocoordinates 41.0° N, 8.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Lower Freestone Formation (Inferior Oolite Group), Middle Jurassic (174.7 - 161.5 Ma)

• "233ft 4in - 346ft 2in" (Melville 1956)

• group of beds-level stratigraphic resolution

Environment/lithology: ooidal, sandy limestone

• "The bulk of the Lower Freestone is white to grey or fawn current-bedded oolite. The lowest third contains much sand; comminuted shell-debris and small, rounded pellets of calcite-mudstone are scattered throughout. The basal 3.5ft were decalcified, with soft, chalky ooliths in a porous friable matrix." (Green & Melville 1956)

Size class: macrofossils

Preservation: mold/impression

Reposited in the BGS

Collection methods: core
