Ichthyolith counts (>38µm) and calculated ichthyolith accumulation rates determined in this study. Age model after Mackensen and Ehrmann 1992. (Table 2). Adjusted to GTS 2012; See Table S6 (this study doi:10.1594/PANGAEA.910669). Sediment dry bulk density (DBD) from: Faul and Delany 2010 (Table S2b), data: doi:10.1594/PANGAEA.831403. Variable DBD does not make a significant difference in calcualations of IAR (See supplement to: Sibertet al. 2014). 64695 Used varibale dry bulk density values in figures.
