Whitecliff Bay, Barton Beds (Bed 11) Isle of Wight (Eocene of the United Kingdom)

Where: England, United Kingdom (50.7° N, 1.1° W: paleocoordinates 48.5° N, 5.0° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

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

• This bed is part of the "London Clay" sequence recognized by Prestwich and Bowerbank. I'm using Prestwich's numbering system for the unit (Bowerbank numbers it 12). I have correlated it with Bosma's naming system as the Barton Beds. When adding the occurrences from Gardner et al., this is a best-guess (based on fossil occur.) in correlating this bed with their Lower Barton fossils.

• bed-level stratigraphic resolution

Environment/lithology: marine; pebbly, shelly/skeletal, sandy, calcareous claystone and concretionary, green, calcareous sandstone

• This bed is massive light and dark-coloured slightly calcareous greensand with small soft white calcareous concretions, the upper half has numerous shells and teeth. This unit in general is clay with sands and marls, in places it has pebble or shell beds.

Size class: macrofossils
