Where: England, United Kingdom (52.2° N, 0.1° E: paleocoordinates 40.6° N, 2.7° E)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Cambridge Greensand Member (West Melbury Marly Chalk Formation), Late/Upper Albian (105.3 - 99.6 Ma)
• Remanie fauna - reworked from late Albian into early Cenomanian deposits. Faunal assemblage is late Albian in age (age used here). "Although the deposit itself is generally considered to be of late Cretaceous, Cenomanian age, its macrofossil assemblage is thought to be derived largely from the underlying early Cretaceous, Albian, Gault Formation, on the basis of derived ammonites associated with the vertebrate fossils. An early Cenomanian age for deposition of the Cambridge Greensand is based on an apparently autochthonous foraminiferan assemblage, but Morter and Wood (1983) could not rule out the possibility of a very late Albian age due to the presence of the bivalve Aucinella. The age of the derived vertebrates is now considered to be no older than the Callihoplites auritus ammonite subzone and most likely no younger than upper Stoliczkaia dispar Zone, and they are thus of late Albian age."
