The zone is thus characterised by the co-occurrence of &#039;&#039;G. quadrata&#039;&#039; &#039;&#039;gracilis&#039;&#039; and &#039;&#039;B. mucronata&#039;&#039;.<br /> <br /> &#039;&#039;&#039;Biostratigraphical correlation&#039;&#039;&#039;: The zone equates with the top of the &#039;&#039;G. quadrata&#039;&#039; Zone (top &#039;post &#039;&#039;Applinocrinus&#039;&#039; beds&#039;) of the standard macrofossil zonal scheme for the UK Chalk Group (Christensen, 1991).<br /> <br /> &#039;&#039;&#039;Lithostratigraphical correlation&#039;&#039;&#039;: The zone can be inferred to equate with the basal part of the Portsdown Chalk Formation of southern England.<br /> <br /> &#039;&#039;&#039;Age&#039;&#039;&#039;: Campanian (Christensen, 1991).<br /> <br /> [[Category:Belemnite zonation for the Upper Coniacian, Santonian &amp; Lower Campanian of the UK | 008]]</div>
