希腊罗兹岛的石灰岩岩溶地貌，在上新世晚期开始被构造主导的海侵所淹没。与海水接触的表面被钻孔和锉削的生物群落雕刻。一个凸起的悬崖，详细研究，包括栖息地，如悬崖脚下的平台，陡峭的表面沿着悬崖线，一个洞穴，和悬垂。每个栖息地都有一个独特的生物侵蚀雕塑。四个痕迹化石套件被确认，包括六个遗迹群落，不同的内石器时代古群落的工作环境，从照明，浅水悬崖面到黑暗，宁静的洞穴内部。随着海侵的进行，地表暴露在加深的水中，新的遗迹化石叠加在旧的遗迹化石上。共鉴定出31种遗迹种，分别属于柄链藻属、毛壳藻属、壳孔藻属、Entobia属、腹壳藻属、颚形藻属、Maeandropolydora属、Oichnus属、Phrixichnus（新）属、Radulichnus属、Renichnus属、Rogerella属.
A limestone karst topography on the island of Rhodes, Greece, was flooded by a tectonically dominated transgression starting in late Pliocene time. Surfaces in contact with seawater were sculptured by communities of boring and rasping organisms. A raised cliff, studied in detail, comprises habitats such as a cliff‐foot platform, steep surfaces along the cliffline, a cave, and overhangs. Each habitat has a distinctive bioerosion sculpture. Four trace fossil suites were recognized, comprising six ichnocoenoses, the work of different endolithic paleocommunities in environments ranging from illuminated, shallow water cliff‐face to aphotic, tranquil inner reaches of the cave. As the transgression progressed, and surfaces were exposed to deepening water, new trace fossils were superimposed on old. Thirty‐one ichnospecies were identified, belonging to Caulostrepsis, Cen‐trichnus, Conchotrema, Entobia, Gastrochaenolites, Gnathichnus, Maeandropolydora, Oichnus, Phrixichnus (new), Radulichnus, Ren‐ichnus, Rogerella...
