Stowell Park borehole (?Sharp's Hill Beds, 114-118ft) (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: Stonesfield Slate Formation (Great Oolite Group), Middle Jurassic (174.7 - 161.5 Ma)

• "113ft 7in - 118ft 5in" (Melville 1956)

• group of beds-level stratigraphic resolution

Environment/lithology: estuary or bay; brown, green claystone and limestone

• "Beneath the lower sandy and marly oolitic limestones lies a group of blotchy green yellow and brownish clays and thin limestones. The lithology recalls some of the clays of the Upper Estuarine Series of Northamptonshire and the impression of an estuarine environment is strengthened by certain faunal resemblances to the Sharp's Hill Beds, with which these beds are tentatively correlated." (Green & Melville 1956)

Size class: macrofossils

Preservation: mold/impression

Reposited in the BGS
