Where: England, United Kingdom (50.6° N, 1.6° W: paleocoordinates 49.1° N, 5.4° W)

• coordinate estimated from map

When: Upper Headon Beds Formation, Late/Upper Eocene (37.2 - 33.9 Ma)

• This author considers the Upper Headon Beds to be a formation, HH4 refers to a locality within a unit (maximally 15 cm thick), just above a lignite band (the band separates HH3 and HH4).

• bed-level stratigraphic resolution

Environment/lithology: marine; silty, sandy, calcareous claystone and shelly/skeletal, brown, silty marl

Size classes: macrofossils, mesofossils

Collection methods: bulk, sieve,

• This is probably the same location used by Prestwich, 1946, but his stratigraphy is all screwed up, it is my guess that HH3 and HH4 are within his beds 55-57
