Abstract:
Ichthyolith counts (>106µm) and calculated ichthyolith accumulation rates used in this study. This data was originally published in Sibert et al. 2016.
Age, DBD, and MAR based on age model and linear sedimentation rates of Snoeckx et al. 1995.
Ichthyolith counts from the above study were scaled from >106um to >38µm using the ratio of ichthyoliths in the 106um fraction to the total teeth per tooth >106µm. 38µm fraction common to all other sites in this study, determined to be ich >38µm = 4.25 * ich >106µm, denoted as 'scaled' columns in this table
