滑石板阶标准剖面的牙形刺主要有Neognathodus symmetricus, Declinognathodus noduliferus noduliferus, D.noduliferus inaequalis, D.lateralis, Idiognathoides corrugatus, I. sinuatus和I.sulcatus等,应属Neognathodus symmetricus带;滑石板阶之底界则在Neognathodus symmetricus带中通过.由此可知,在标准剖面上,滑石板阶的大部应与国际地层表中的巴什基尔阶或北美莫罗阶中部相当.
滑石闆階標準剖麵的牙形刺主要有Neognathodus symmetricus, Declinognathodus noduliferus noduliferus, D.noduliferus inaequalis, D.lateralis, Idiognathoides corrugatus, I. sinuatus和I.sulcatus等,應屬Neognathodus symmetricus帶;滑石闆階之底界則在Neognathodus symmetricus帶中通過.由此可知,在標準剖麵上,滑石闆階的大部應與國際地層錶中的巴什基爾階或北美莫囉階中部相噹.
