论文描述的双壳类壳体内的钻孔遗迹组合发现于湖南省东南部宜章县下坪附近的心田门组上部(早侏罗世,早辛涅缪尔期)浅海沉积地层中。这个遗迹化石群中,帚虫类动物制造的钻孔Talpinahunanensisichnosp.nov.(新遗迹化石种)明显地占据了大部分,偶尔共生的其它钻孔包括:Rogerellaichnosp.(蔓足亚纲尖胸类的遗迹)、Calcideletrixichnosp.(可能是藻类的遗迹)、藻或菌造的遗迹(暂定为“Mycelites”ichnosp.)、以及一种可能被海绵动物制造的未定钻孔。生物侵蚀者侵害了海底上较大的双壳类壳体。钻孔保存为天然印模(石核),它们是文石质壳体溶解后留下的空间中的充填物。此外,文中还讨论了遗迹化石属TalpinaHagenow,1840,尤其讨论了有关遗迹种颇为复杂的鉴别问题,同时校正了该遗迹属的属征。
The borehole assemblages in the bivalve shells described in the paper were found in shallow marine sedimentary formations in the upper part of the Xintianmen Formation (Early Jurassic, Early Sinuilleal) near Xiaping, Yizhang County, southeastern Hunan. Among this group of fossil fossils, the boreholes Talpinahunanensisichnosp. Nov. (A new fossil species) apparently made up of spiders clearly occupy most of the other boreholes occasionally symbiotic, including: Rogerellaichnosp. (Possibly a relic of algae), remains of algae or bacteria (tentatively named “Mycelites” ichnosp.), And an undetermined borehole that may be made of sponges. Biological attackers invade the larger bivalve shell on the sea floor. Drilled holes are preserved as natural impressions (stone core), which are fillings in the space left by the aesthetical body shell. In addition, TalpinaHagenow, 1840, is also discussed in this paper. In particular, it deals with the rather complex identification problems associated with the relics and at the same time corrects the signatures of the remains.
