Cliffend, Middle Barton Beds, C, Hampshire (Eocene of the United Kingdom)

Where: England, United Kingdom (50.7° N, 1.7° W: paleocoordinates 49.2° N, 5.6° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Middle Member (Barton Beds Formation), Late/Upper Eocene (37.2 - 33.9 Ma)

• this bed is 6 ft thick, the lettering of the beds starts with the lowest Barton beds, this is the first in the Middle Barton Series

• bed-level stratigraphic resolution

Environment/lithology: marine; gypsiferous, pebbly, shelly/skeletal claystone

• above horizon B, the clay becomes darker in texture, it is coarse and gritty owing to the presence of numerous subangular pebbles incorporated with the finer argillaceous material, the upper limit is devined by a layer of septaria.

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.
