通过对柯坪地区剖面志留系的研究,在柯坪塔格组中已识别出遗迹化石15属20种,它们是:Asterichnus lawrencensis,Cochlichnus anguineus, Cruziana ichnosp., Cruziana qinlingensis, Cruziana rouaulti, Diplichnites bipartibilis,Gordia molassica, Helminthopsis abeli, Helminthopsis isp., Lockeia siliquaria,Monocraterion cf. teataculatum, Palaeophycus tubularis, Planolites isp.,Planolites montanus, Planolites punctatus, Rusophycus ramellensis,?Scolicia ichnosp., Sagittichnus lincki,Spirophycus bicornis,Taenidium cameronensis.根据这些遗迹化石的组成、产状、分布规律及其围岩的沉积特征,可以划分为两种不同沉积环境条件下的遗迹组合,即①Helminthopsis-Gordia遗迹组合, 主要组成分子有Asterichnus, Diplichnites,Gorida, Helminthopsis, Planolites, Rusophycus,?Scolicia和Spirophycus等,被解释形成于低能的滨外远岸浅海陆棚环境;②Cruziana-Rusophycus遗迹组合,常见组成分子有Cochlichnus,Cruziana, Lockeia, Palaeophycus,Rusophycus, Monocraterion,Sagittichnus,和Taenidium等,解释它们形成于滨外近岸浅海陆棚环境.
