在天山志留系、石炭系和东昆仑-西秦岭三叠系浊积岩系中遗迹化石发育，经研究计有：Helminthopsis hieroglyphica, Neonereites biserialis, N. uniserialis, Palaeophycus isp., P. serratus, P. striatus, P. tubularis, Paleodictyon imperfectum, Phycodes circinnatum, Phycosiphon incertum, Planolites annularis, P. beverleyensis, P. montanus, Rhizocorallium isp., Scalarituba missouriensis, Skolithos isp., ? Spirorhaphe isp., Sublorenzinia isp. Tambia isp., Taphrhelminthopsis auricularis, Teichichnus isp., Thalassinoides isp.。它们构成4种遗迹化石组合：Phycosiphon-Palaeophycus 组合、Neonereites-Scalarituba组合、Paleodictyon组合和Phycodes-Skolithos组合，分别代表局限缺氧深海盆地浊流沉积、半深海环境的中-上扇沉积、多岛洋环境的中-下扇沉积、半深海环境的中扇浊流沉积。“,”Twenty-two ichnotaxa have been found in the Silurian and Carboniferous turbidites of the Tianshan orogenic belt and the Triassic turbidites of the East Kunlun-West Qinling orogenic belt of northwestern China. They are Helminthopsis hieroglyphica, Neonereites biserialis, N. uniserialis, Palaeophycus isp., P. serratus, P. striatus, P. tubularis, Paleodictyon imperfectum, Phycodes circinnatum, Phycosiphon incertum, Planolites annularis, P. beverleyensis, P. montanus, Rhizocorallium isp., Scalarituba missouriensis, Skolithos isp., ? Spirorhaphe isp., Sublorenzinia isp., Tambia isp., Taphrhelminthopsis auricularis, Teichichnus isp., and Thalassinoides isp. These trace fossils can be grouped into four ichno-assemblages: Phycosiphon-Palaeophycus ichno-assemblage representing turbidity current deposits of a restricted anoxic deep-sea basin, Neonereites-Scalarituba ichno-assemblage representing the upper-middle turbidity fan deposits of a pelagic and hemipelagic environment., Paleodictyon ichno-assemblage representing the middle-lower turbidity fan deposits of an oceanic archipelago, and Phycodes-Skolithos ichno-assemblage showing middle turbidity fan environments.
