Abstract Ichnological analysis was conducted in the late Miocene sandy clastic contouritic deposits from the Rifian Corridor (Morocco). The Rifian Corridor was a main gateway between the Mediterranean Sea and the Atlantic Ocean during the late Miocene. An initial detailed ichnological analysis of clastic contourite facies revealed trace fossil assemblages of high abundance (similar to that of calcareous contourites) and low ichnodiversity. Parahaentzschelinia and Rosselia were registered for the first time in contouritic facies. Scolicia and Macaronichnus were found to be the dominant ichnogenera in the studied sandy clastic contourites. Abundant Macaronichnus, Parahaentzschelinia and Scolicia evidence the adaptation of trace makers to “unfavourable” energetic conditions, food availability being a major parameter that favoured opportunistic colonization of the supposedly “un-inhabitable” high-energy contourite depositional setting. Similar ichnological studies conducted in selected outcrops will allow us to address the representative ichnoassemblage of coarser (silty/sandy) clastic contourites.

晚中新世 Rifian 走廊（摩洛哥）砂质碎屑等高沉积物的痕量化石分析：Ichnotaxonomical 和古环境见解

摘要 对摩洛哥里夫安走廊晚中新世砂质碎屑等高岩沉积进行了地质学分析。里菲亚走廊是中新世晚期地中海和大西洋之间的主要门户。对碎屑等深岩相的初步详细地质学分析揭示了高丰度（类似于钙质等高岩）和低地层多样性的痕量化石组合。Parahaentzschelinia 和 Rosselia 首次在等高相中被记录。Scolicia 和 Macaronichnus 被发现是研究的砂质碎屑等高岩中的优势鱼属。丰富的 Macaronichnus、Parahaentzschelinia 和 Scolicia 证明了痕迹制造商对“不利”的能量条件的适应，食物供应是一个主要参数，有利于在所谓的“不适合居住”的高能量等高线沉积环境中进行机会主义殖民。在选定的露头中进行的类似地层学研究将使我们能够解决较粗（粉砂质/砂质）碎屑等高岩的代表性地层组合。
