南极詹姆斯罗斯岛晚白垩世隐湖组发现一新遗迹分类群。Fuersichnus striatus由水平到近水平、孤立或松散聚集、U形、弯曲至香蕉状的洞穴组成，其特征是平行于痕迹轴的独特条纹。它被解释为可能由甲壳类动物或多毛类动物产生的居住结构。这一记录将Fuersichnus的地层范围从三叠纪-侏罗纪扩展到白垩纪，其环境背景从非海洋环境扩展到海洋环境。F. striatus代表了固结的，但未石化的基板。因此，它必须被认为是Glossifungites遗迹相的成员。
A new ichnotaxon is recognized in the Hidden Lake Formation, Upper Cretaceous of James Ross Island, Antarctica. Fuersichnus striatus consists of horizontal to subhorizontal, isolated or loosely clustered, U‐shaped, curved to banana‐like burrows, characterized by distinctive striations parallel to the trace axis. It is interpreted as a dwelling structure probably produced by crustaceans or polychaetes. This recording of Fuersichnus extends its stratigraphic range from the Triassic‐Jurassic to the Cretaceous and its environmental setting from nonmarine to marine environments. F. striatus typified consolidated, but unlithified substrates. Accordingly, it must be considered a member of the Glossifungites ichnofacies.
