St. Lawrence, Isle of Wight (upper Upper Greensand) (Cretaceous to of the United Kingdom)

Where: England, United Kingdom (50.6° N, 1.2° W)

• Paleocoordinates: 47.4° N, 18.0° E (Wright 2013)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Upper Chert and Rag Member (Upper Greensand Formation), Albian to Albian (113.0 - 93.5 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified chert and coarse-grained, green sandstone

• "The red sands give place to alternate bands of hard chert and coarse greensands (vide section). In the 6 feet of inferior building-stone A. rostratus attains its greatest development, and casts of large Nautili are common. This is divided from the building-freestone (which hardens on exposure to the atmosphere) by one foot of blue chert, having another chert band on the top little else but a mass of sponge-spicules embedded in siliceous matrix. " (Parkinson 1881)

Size class: macrofossils
