TL;DR: In this paper, a number of transects were sampled over a variety of reefs in Bermuda and an analysis was made of the borings and their inhabitants, including 25 endolithic species, including sponges, a sea anemone, sipunculids, annelids, bivalves, a gastropod, a barnacle and an echinoid.
TL;DR: The island of Rhodes, Greece, was flooded by a tectonically dominated transgression starting in late Pliocene time as discussed by the authors, and the surface in contact with seawater was sculptured by communities of boring and rasping organisms.
Abstract: 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...
TL;DR: An Entobia is established for trace fossil assemblages dominated by deep tier borings and arising from long-term bioerosion, such as occurs on sediment-free submarine cliffs or hardgrounds as discussed by the authors.
Abstract: In bioerosion, as in trace fossils as a whole, deeply emplaced structures have greater survival value than shallow structures. That is to say, tiering (the relative depth to which rasping, etching and boring organisms penetrate their substrate) is of paramount importance for the preservation potential of individual trace fossils. An Entobia ichnofacies is established for trace fossil assemblages dominated by deep tier borings and arising from long-term bioerosion, such as occurs on sediment-free submarine cliffs or hardgrounds. A Gnathichnus ichnofacies comprises assemblages containing all tiers, including superficial sculptures produced by radulation that have very little preservation potential. Such assemblages occur in short-term bioerosion situations as on shell surfaces and hardgrounds buried early by sedimentation.
TL;DR: In this paper, the same Gastrochaenolites-Entobia assemblage has been described from Mesozoic and Cenozoic rocky shores around the world.
Abstract: Ichnological study of Lower Pliocene rocky shores in several northwestern Mediterranean basins has revealed the existence of a recurrent trace fossil assemblage of borings. This assemblage is dominated by the ichnogenera Gastrochaenolites and Entobia, which often are accompanied by other borings, such as Maeandropolydora, Caulostrepsis, Trypanites, Circolites, Iramena, and unnamed U-shaped borings. The same Gastrochaenolites-Entobia assemblage has been described from Mesozoic and Cenozoic rocky shores around the world, and these observations validate the recently proposed Entobia ichnofacies as a recurrent ichnofacies for post-Paleozoic rocky shores.
