Where: England, United Kingdom (50.6° N, 1.6° W: paleocoordinates 49.1° N, 5.4° W)
• coordinate estimated from map
When: Lower Headon Beds Formation, Late/Upper Eocene (37.2 - 33.9 Ma)
• This author considers the Lower Headon Beds to be a formation, HH2 refers to a locality in the second lowest mammal-bearing unit (thickness approximately 15 cm), which passes upwards into a lignitic clay (thickness approx. 5 cm). This is the upper portion of the Lower Headon Beds (approx. 18 m above HH1)
• bed-level stratigraphic resolution
Environment/lithology: marine; silty, sandy, calcareous claystone and shelly/skeletal, green, calcareous, carbonaceous claystone
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 HH2 is the same as his bed 45
