Gastrochaenolites hospitium isp. nov., trace fossil by a coral-associated boring bivalve from the Eocene and Miocene of Austria

Abstract: Gastrochaenolites hospitiumisp. nov., trace fossil by a coral-associated boring bivalve from the Eocene and Miocene of AustriaGastrochaenolites hospitiumisp. nov. is a domichnial boring showing the so-called false floors in scleractinian coral skeletons. The borings are semi-circular in mid-longitudinal section. They are produced by the mytilidLithophaga (Leiosolenus) and keep up with further growth of their hosts for years. The false floors, being a retrusive equilibrium trace, are related to annual events.

“…In both modern-day and ancient reef environments, borers are known to colonize not only hardgrounds or shells, but also coral skeletons (Jones and Pemberton, 1988;Perry, 2000;Perry and Hepburn, 2008;Valentich-Scott and Tongkerd, 2008;Martinell and Domènech, 2009;Abdel-Fattah and Assal, 2016;El-Hedeny and El-Sabbagh, 2018), establishing a symbiotic relationship, with the bivalve borers shifting laterally in order to keep pace with the coral growth (Morton, 1990;Kleemann, 2009). This codevelopment of reef and endolithic communities is useful to evaluate timing and preferred coral growth, allowing us to identify anomalies in these patterns, which are of particular importance when related to changes in sea-water depth.…”

“…By presenting the host range of boring mussels and by showing the morphological range of their borehole orifices, we aim to facilitate the easy detection of these bioeroding organisms in future research. Our findings may also help in the interpretation of fossil holes of boring mussels, recognized as trace fossils of the ichnogenus Gastrochaenolites, and may tell us more about the condition and habitat of their host corals or other substrates when these were still alive [4,[55][56][57][58][59].…”

“…The diagnostic characters used to distinguish the species are the shape of the main chamber, the occurrence of one or two tubes in the neck region, and the shape (bilobate, smooth, parabolic) of the base of the boring (e.g. Kelly 1980;Kelly & Bromely 1984;Edinger & Risk 1994;Ekdale & Bromley 2001;Donovan 2002;Kleemann 2009;Rahman et al 2015). The species identification needs, therefore, well preserved ichnospecimens or representative sections showing these diagnostic characters (Bertling et al 2006), as with the investigated specimens.…”

“…In hard carbonate substrate such as shells boring bivalves inhabiting holes are sedentary and boring is accomplished by secretion of low pH chemicals and/or mechanical rasping (Kleemann 1996;Taylor & Wilson 2003). Most boring mytilids are chemical borers and prefer hard carbonate substrates, while all pholadids are mechanical borers preferring firmgrounds such as hardened mud and wooden substrates (Savazzi 1999;Owada 2007Owada , 2009Owada , 2015.…”
