base notes	potential GSSP may coincide with lowest occurrence of calpionellid Calpionellites darderi (base of Calpionellid Zone E); followed by the lowest occurrence of ammonite ""Thurmanniceras"" pertransiens.				comp notes	It seems that the T. otopeta TAsZ has been moved from the Valanginan to the Berriasian to which makes some of the older notes confusing. In addition the stage base in the Stage Summary/Cret output/TSC is different to that on the CRET Macro sheet Base Calp darderi (137.7 Ma) CalpZ vs 0.3 M14r (137.44 Ma)
