Where: England, United Kingdom (53.5° N, 0.3° W: paleocoordinates 44.3° N, 9.2° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Lower Member (Spilsby Sandstone Formation), Late/Upper Tithonian to Late/Upper Tithonian (150.8 - 140.2 Ma)
• Some of the elements were found in the basal Spilsby nodule bed (which is probably late Tithonian) and others in the overlying argillaceous sandstone (earliest Berriasian)
Environment/lithology: lagoonal; glauconitic, pebbly, phosphatic, gray, green sandstone
Size class: macrofossils
Collected by Pauline Taylor (and others) in 1999 and subsequent visits
