Potton bonebed (Cretaceous of the United Kingdom)

Also known as Craterosaurus type

Where: England, United Kingdom (52.1° N, 0.2° E: paleocoordinates 42.2° N, 10.9° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Potton Nodule Bed Member (Woburn Sand Formation), Early/Lower Aptian (125.5 - 122.5 Ma)

• Potton Sands = Woburn Sands; possibly reworked. "it may be as new as the upper part of the Lower Greensand" (Seeley, 1874).

• formation-level stratigraphic resolution

Environment/lithology: terrestrial; concretionary, phosphatic, brown sandstone

• "the bed of phosphatic nodules which there occurs in the brown sands, named by Conybeare and Fitton Woburn sands"

Size class: macrofossils

Collection methods: quarrying, mechanical,
