Brook pterosaurs (PROXY) (Cretaceous to of the United Kingdom)

Where: England, United Kingdom (50.6° N, 1.5° W: paleocoordinates 40.8° N, 9.4° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Wessex Formation (Wealden Group), Barremian to Barremian (130.0 - 122.5 Ma)

• "This material cannot be satisfactorily assigned to a Wealden Group horizon" (Sweetman & Martill 2010). However, if the locality "Brook" refers to Brook Bay, rather than a wider vicinity, then the specimen is likely from the Wessex Formation because the Vectis Formation is not present at Brook Bay (Sweetman & Martill 2010).

• bed-level stratigraphic resolution

Environment/lithology: crevasse splay; conglomerate and mudstone

• Wessex Formation was "deposited in a meander-belt river system with a dominant flow direction from west to east"
• Bed CL3 is a "plant debris bed". "The lower part of most plant debris beds comprises a poorly sorted, matrix-supported conglomerate. The upper part of most consists of structureless mudstone, which usually grades up into colour-mottled but predominantly red and purple floodplain mudstones." (Sweetman & Insole 2010 PPP 292:409)

Size class: macrofossils
