Also known as Snowshill Quarry
Where: England, United Kingdom (52.0° N, 1.8° W)
• Paleocoordinates: 35.9° N, 19.1° E (Wright 2013)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Zigzagiceras zigzag zone, Chipping Norton Limestone Formation (Great Oolite Group), Early/Lower Bathonian (167.7 - 164.7 Ma)
• "Hornsleasow Clay Unit" placed between Chipping Norton Member (above) and Hook Norton Member (below). Upper part of unit is the "Green Clay" and lower part is the "Grey Clay". From the macrescens Subzone of the zigzag Zone
• bed-level stratigraphic resolution
Environment/lithology: karst; bioturbated, pebbly, carbonaceous claystone and claystone
•Secondary (Green Clay): "more homogenous than the Grey Clay. Limestone clasts and sand make up only 3 percent of the composition by weight. The deposit has more silica and sand and is an illite/chlorite clay. Vertical rootlets pervade the layer, extending from the mud-cracked, upper surface...into the underlying Grey Clay...The plant material is somewhat oxidized."
Size classes: macrofossils, mesofossils, microfossils
