| Geological group: | Ancholme | Formation: | Oxford Clay | Member: | Weymouth |
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: "St Ives is situated on the easternmost part of the Oxford Clay Formation outcrop and both Arkell (1933) and Edmonds and Dinham (1965) regard the St Ives clay pits as having been excavated in the Upper Oxford Clay (now called Weymouth Member; see Cox et al. 1992) and close to the Oxford Clay/West Walton Beds boundary. Thus ‘R’ jessoni is also from the Upper Jurassic, albeit the lowest part." (Martill & Etches 2011) | |||||
