Abstract

Trace fossils recording the activity of organisms are common in the Ordovician terrigenous deposits of Tuva. The richest location of ichnofossils was found in the Chirgaky section in the western part of the region. Ichnofossil taxa such as Dimorphichnus Seilacher and Helmintopsis Heer have already been sporadically recorded in other regions of the world. Along with them, the author found predominant trace fossils which should be attributed to a new species of a new subgenus of the genus Rusophycus Hall.

Rusophycus (Hemisphaerichnus) Communitas——来自图瓦地区奥陶纪的一个新的石化石分类群

摘要

记录生物活动的痕迹化石在图瓦的奥陶纪陆源沉积物中很常见。在该地区西部的 Chirgaky 部分发现了最丰富的 ichnofossils 位置。石化石类群，如Dimorphichnus Seilacher 和Helmintopsis Heer 已经在世界其他地区零星记录。与他们一起，作者发现了主要的痕迹化石，这些化石应该归因于Rusophycus Hall属的一个新亚属的一个新物种。
