Aldeburgh, Suffolk (TM 458580)
Just over 2m of Aldeburgh Member are exposed in this old quarry, once the site of a market garden. Crag Pit Nursery is the most northern onshore exposure of the Coralline Crag. Compared with Aldeburgh Hall, large cyclostome bryozoans are less common but the locality is important for the occurrence of a rich bryozoan fauna encrusting pectinid shells. This locality is interpreted as representative of the ‘source area’ for the carbonate sand that was swept south-westwards by tidal currents along the linear sand bank which now forms the sandwave facies of the Sudbourne Member.
