'''Age:''' Earliest Maastrichtian.<br />
<br />
'''Macrofaunal correlation''': The ''B. lanceolata'' Zone.<br />
<br />
'''Definition:''' The interval between the'' ''LAD of ''Palaeohystrichophora infusorioides ''and'' ''the LAD of ''Neoeurysphaeridium glabrum.''<br />
<br />
'''Comments:''' Alternative biomarkers for the top of this biozone are the LADS of ''Eatonicysta hapala, Odontochitina costata'', ''Odontochitina operculata'' and ''Turnhosphaera hypoflata'' (see Kjellström, 1973; Wilson, 1974; Haq ''et al''., 1987; Costa & Davey, 1992; Schiøler & Wilson, 1993; Foucher & Monteil, 1998). The FAD of ''Triblastula utinensis'' typically occurs within this biozone (Wilson, 1974; Schiøler & Wilson, 1993).<br />
<br />
'''Lithostratigraphical correlation''': The Sidestrand Chalk and the Trimingham Sponge Beds members (East Anglia) and the Mackerel Formation (North Sea).<br />
