Gastrochaenolites
Gastrochaenolites (G) and Entobia (E) in limestone cobble from the Los Banós Formation, Upper Miocene, SE Spain.
Gastrochaenolites is a trace fossil formed as a clavate (club-shaped) boring in a hard substrate such as a shell, rock or carbonate hardground. The aperture of the boring is narrower than the main chamber and may be circular, oval, or dumb-bell shaped (Kelly and Bromley, 1984). Gastrochaenolites is most commonly attributed to bioeroding bivalves such as Lithophaga and Gastrochaena (Kleeman, 1980). The fossil ranges from the Ordovician to the Recent (Taylor and Wilson, 2003; Vinn and Wilson, 2010).
