Trace fossil classification

Chaetosalpinx is an ichnogenus of bioclaustrations (a type of trace fossil). Chaetosalpinx includes straight to sinous cavities that are parallel to the host’s axis of growth. The cavity is circular to oval in cross-section and it lacks a wall lining or floor-like tabulae (Tapanila 2005). They are common in tabulate and rugose corals from Late Ordovician to Devonian of Europe and North America (Tapanila 2005, Mõtus and Vinn 2009). They may have been parasites (Zapalski 2007).
