Staple Pit (Triassic of the United Kingdom)

Where: England, United Kingdom (53.0° N, 0.8° W: paleocoordinates 37.8° N, 1.4° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Westbury Formation (Penarth Group), Rhaetian (208.5 - 201.3 Ma)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; phosphatic, sandy conglomerate and pyritic sandstone

• "a thin conglomerate (0-3cm) containing phopatised coprolites up to 12 cm long. White and pink quartz pebbles are also abundant. The whole is enclosed in a sandy matrix, portions of which are cemented by pyrite. Small authigenic bipyramidal quartz crystals have also been found in this horizon."
