Ichnological features of a marine transgression: Middle Miocene Rocky Shores of Tarragona, Spain

Extreme habitat adaptation by boring bivalves on volcanically active paleoshores from North Atlantic Macaronesia

“…However, diVerences concerning Gastrochaenolites density are evident. The more easily penetrated substrates normally have a boring community with the highest density (e.g., Lewy 1985;Watkins 1990;Domènech et al 2001;Johnson et al 2011b). In most of the harder substrates, i.e., greywacke, basalt or calcareous arkose, the density of borers is very low (McHuron 1976).…”

Sedimentology, architecture, and sequence stratigraphy of coarse-grained, submarine canyon fills from the Pleistocene (Gelasian-Calabrian) of the Peri-Adriatic basin, central Italy

“…Finally, the presence of reworked shallow-marine molluscs and Entobia and Gastrochaenolites trace fossils, which have been commonly recognised in Neogene rocky shorelines and gravel beach deposits (e.g. Watkins, 1990;de Gibert et al, 1998;Domènech et al, 2001), suggests that these clasts resided for at least some time in the littoral zone before final burial at upper bathyal depths. Similarly, the well-rounded nature of the extrabasinal clasts implies a fluvial or shallow shelf origin.…”

The bioeroded megasurface of Oura (Algarve, south Portugal): implications for the Neogene stratigraphy and tectonic evolution of southwest Iberia

“…The existence in the Iberian Neogene of basal transgressive surfaces aVected by bioerosion structures indicative of ancient rocky shores or hardgrounds of Miocene age has been abundantly documented in the last 15 years (e.g., de Gibert et al 1996;Mayoral et al 1998;da Silva et al 1999;Domènech et al 2001;Santos et al 2008). However, only recently such a bioeroded surface has been identiWed in an intra-Miocene position at Oura Domènech et al 1999).…”

“…They represent a marine sedimentary environment in which erosion processes dominate (rather than depositional processes) and where wave-cut marine erosion platforms are being formed. Therefore, the recognition of rocky palaeoshores in the geological record is of paramount importance, for they characterize major Xooding surfaces and provide crucial information about palaeoshorelines and ancient sea levels (Martinell and Domènech 1995;Jia-Yu and Johnson 1996;Ghibaudo et al 1996;de Gibert et al 1996;da Silva et al 1999;Domènech et al 2001;Santos et al 2008).…”
