Comment:
Ichthyolith counts were made based on images of samples processed in ImageJ for serial 165-230; For all others, counts done manually. These ichthyolith counts (total >106 microns) were collected as part of a prior study: Sibert et al. (2014). Here we report teeth and denticles >106 microns, which was not designated in the prior study.
