Cliffend, Lower Barton Beds, B, Hampshire (Eocene of the United Kingdom)

Where: England, United Kingdom (50.7° N, 1.7° W: paleocoordinates 48.6° N, 5.6° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Barton Clay Formation, Bartonian (41.3 - 38.0 Ma)

• "Lower Barton Beds"; this bed is 4 ft thick

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; concretionary, glauconitic, gray, sandy claystone

• Upper parts of the Lower Barton Beds contains "sandy clays with storm-generated laminated sand and shell beds." Poor preservation of shell ornament also interpreted as abrasion by currents.
• grey sandy and glauconitic clay, overlain by a line of irregularly-spaced concretions

Size class: macrofossils

Collection methods: In the introduction, Burton says that he is reporting fauna "the horizons of which are known to the author", and states that he has collected 480 specimens. It is also clear that he is pulling from other sources, some published (in difficult to obtain British journals), some not. It's difficult to tell which are his and which aren't. This is not a definitive source for this collection, but I think it's a reasonable place to start.
