Figure 5.8
Yorkshire East Quarry, Conesby; trial excavation in mid-1995, prior to SSSI notification. The lower face shows around 7 m of bedded Frodingham Ironstone Member above water level, with the top 1 m corresponding to beds 20–23 and yielding late Stellare to Denotatus subzone faunas. Above, and in the rear cliff, around 3.5 m of Charmouth Mudstone Formation can be seen, of Simpsoni Subzone age. The succession is capped by Quaternary ‘Cover Sands’. (Photo: K.N. Page.)

Figure 5.12
The Upper Pliensbachian succession exposed at the Napton Hill Quarry GCR site. The Marlstone Rock Formation lies at the top of the section, with the sandstone of Bed 33 visible a little lower in the face. The large blocks projecting from the lower part of the right-hand face are some of the doggers that occur in Bed 29. (Photo: M.J. Simms.)
