Chalk Group Lithostratigraphy: Northern England - Lower Inoceramus Bed

The lower Inoceramus Bed (c. 1 m thick in the Hull-Brigg district), like its East Anglian correlative, comprises coarse-grained chalk with large shell fragments and complete specimens of the inoceramid bivalve Inoceramus crippsi (Gaunt et al., 1992). In the Hull-Brigg district it also has a rich fauna of serpulids and brachiopods, and glauconitised pebbles associated with numerous Holaster occur at the base of the bed (Gaunt et al., 1992).

Macrofossil Biozonation: M. mantelli Zone, ?S. schlueteri Subzone
