Where: England, United Kingdom (50.7° N, 2.1° W: paleocoordinates 48.5° N, 6.0° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: MP16 zone, Creechbarrow Limestone Formation, Bartonian (41.3 - 38.0 Ma)
• This is the only known outcrop of the Creechbarrow Limestone, ranges in thickness from 0-16 m and lies above unnamed sands and clays
•
•"Chreechbarrow Hill is dated to mammal Paleogene Reference Level MP16 and the lautricense-siderolithicum Zone, by comparison with continental European faunas" (Benton et al., 2005)
• formation-level stratigraphic resolution
Environment/lithology: marine; oncoidal, shelly/skeletal, yellow, sandy marl and intraclastic, shelly/skeletal, yellow, silty, sandy marl
•buff marl: a buff calcareous silty clay with abundant angular to subangular quartz grains up to 1 m m in diameter and containing limestone clasts. It also contains oncoliths often containing [mollusc] and vertebrate remains and derived silicified Cretacous bryozoans.
Size classes: macrofossils, mesofossils
Preservation: cast, trace
