Ichthyolith (tooth and denticle) counts from sediment core Gubbio

These ichthyolith counts were collected as part of a prior study, however were lumped as all ichthyoliths >38 µm: Sibert et al. (2014). Here we report the ichthyoliths and classifications >106 µm, a distinction that was not made in the prior study. Age model was developed using published biostratigraphic and magnetostratigraphic datums and updated to GTS2012, please see supplementary data for Sibert et al. (2014) for details.

本研究所用的鱼石（ichthyolith）计数数据采集自一项先期研究，该研究将所有粒径大于38微米的鱼石合并归类，相关成果参见Sibert等人（2014）。本次研究则报道了粒径大于106微米的鱼石及其分类结果，而先期研究并未做出该粒度区分。本研究的年代模型基于已发表的生物地层学与磁地层学基准点构建，并更新至地质年代标尺2012（GTS2012），详细信息请参阅Sibert等人（2014）的补充数据。
