In this research study, 27 ichnospecies belonging to 18 ichnogenera are described for the first time from the lower Miocene Tiaret Marl Formation (north-western Algeria), which consists of thin-to medium-bedded sandstones and marlstones, representing deep-sea fan facies. The sandstones contain the following ichnotaxa: Cardioichnus isp., cf. Chondrites isp., Ophiomorpha isp., Ophiomorpha annulata, Ophiomorpha rudis, Palaeophycus isp., cf. Planolites isp., Planolites montanus, Zoophycos isp., Tisoa siphonalis, Helminthorhaphe isp., Scolicia isp., Scolicia prisca, Scolicia vertebralis, Cosmorhaphe isp., Desmograpton isp., Gordia isp., Helminthopsis isp., Nereites isp., Tubulichnium cf. incertum, Urohelminthoida appendiculata, cf. Megagrapton isp., Paleodictyon minimum, P. strozzii, P. majus, P. (Glenedictyum) miocenicum and P. maximum. The given ichnoassemblage is recorded for the first time from the Miocene of Algeria and assigned to the Nereites ichnofacies, which is typical of marine bathyal depth.

在这项研究中，首次从中新世Tiaret Marl组（阿尔及利亚西北部）描述了属于18个ichnogenera的27个鱼类物种，该组由薄至中层的砂岩和马林岩组成，代表深海扇相。砂岩包含以下鱼鳞生物：Cardioichnus isp。，cf. 球粒陨石的ISP，Ophiomorpha ISP，Ophiomorpha菇，Ophiomorpha rudis，Palaeophycus ISP，比照 Planolites ISP ，Planolites麻雀，Zoophycos ISP，Tisoa siphonalis，Helminthorhaphe ISP，Scolicia ISP，斯里卡斯菌属（Scolicia prisca），椎间盘菌属（Scolicia vertebralis），Cosmorhaphe isp。，Desmograpton isp。，Gordia isp。，Helminthopsis isp。，Nereites isp ，土布利铵cf. incertum，Urohelminthoida appendiculata，比照 Megagrapton isp 。，Paleodictyon最小值，P。strozzii，P。majus，P。（Glenedictyum）miocenicum和P.max 。给定的鱼骨组合首次从阿尔及利亚的中新世开始记录，并分配给Nereites的鱼岩相，这是典型的海洋深海深度。
