base notes	DASHED -- uncertain (no magnetostratigraphy). No subzonal divisions => scaled as "1.5 subzonal units" in relative duration. T. aonoides and T. aon are combined into a general Trachyceras zone in some zonal schemes.				comp notes	In the workbook base T. aon was given an age based on assigning the zone below (D. canadensis) an age of 1/12 interval from the D. candensis to T. subbulatus zone, this seems to be anachronistic approach based on a previous model giving Carnian subzones eqaul duration, so I have simply made this an offset of 0.6 Ma from the base D. candensis/base Carnian
