Stowell Park borehole (Gryphite and buckmani Grits, 206-214ft) (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: Gryphite Grits Formation (Inferior Oolite Group), Middle Jurassic (174.7 - 161.5 Ma)

• "206ft - 214ft 3in" (Melville 1956)

• group of beds-level stratigraphic resolution

Environment/lithology: ooidal, sandy limestone

• "Fine-grained sandy and oolitic limestones extend without lithological change... and although Gryphaea sublobata (Deshayes) is abundant only in the top two feet, it was not possible to separate the Gryphite Grit above from the buckmani Grit below... a bed of black sandy clay with perished chalky shell-fragments is grouped with these beds." (Green & Melville 1956)

Size class: macrofossils

Preservation: mold/impression

Reposited in the BGS

Collection methods: core
