Grange Chine cliff face (MIWG/BMNH) (Cretaceous of the United Kingdom)

Where: England, United Kingdom (50.6° N, 1.4° W: paleocoordinates 40.9° N, 9.3° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Wessex Formation (Wealden Group), Late/Upper Barremian (130.0 - 125.5 Ma)

• about 17 m below the Grange Chine Black Band, in bed L9

• bed-level stratigraphic resolution

Environment/lithology: alluvial fan; pyritic, sideritic, carbonaceous siltstone and claystone

• The palaeoenvironment has been interpreted as a sequence of alluvial meander plains, that overran the Wessex Sub-basin (Allen 1998), together with season- ally ephemeral lakes and ponds (Martill & Naish 2001).
• "a plant debris bed" in a siltstone

Size classes: macrofossils, mesofossils

• Lockwood et al. 2021: The skeleton was found asso- ciated with one of the UK’s most complete theropods, Neovenator salerii Hutt et al., 1996 (MIWG 6348; Brusatte et al. 2008). Both individuals were contained, with some overlap, in an area of ~3x6 m. he then curator is confident that the material was associated (S. Hutt, pers. comm. 2021). Some photographs and drawings of the site are included in Supplementary material (Figs S1–S5) and hard copies of other contemporaneous records have been accessioned under MIWG 6344.
