base notes	DOTTED -- Shown in Mattias Franz et al. (2018; Keuper summary) as ca. 90% up between top of Lehberg Mbr and base of Heldberggips (base of breccia used here); where ages for these are now calibrated via magstrat to Newark etc by Wendy Zhang (2020). FAD of S. weemsi is shown as about 2/3rds up in W. pennslyvanica zone in Fig. 16 of Weems and Lucas (2015); but as top of Hassberge Fm.				comp notes
