Genus

Ropalonaria Ulrich, 1879

Taxon description

Buatois et al., 2017

Category of architectural design: 2.70. Camerate network borings.

Taylor & Wilson, 2003

Remark: Ramifying tunnels with periodic expansions and openings to the surface putatively made by ctenostome bryozoans. Various other ctenostome borings have been named, some as trace fossils but others as body fossils, including Iramena, Orbignyopora, Penetrantia, Pennatichnus, and Pinaceocladichnus. The total range of ctenostome borings is Ordovician– Recent.

Buatois et al., 2017

Among the partly corresponding bryozoan zootaxa, many were described solely on the basis of their borings, and thus should be considered ichnotaxa rather than zootaxa.This concerns for instance Spathipora Fischer, 1866, TerebriporaT d'Orbigny, 1847, Foraripora Voigt and Soule,1973, Ropalonaria Ulrich, 1879, and Orbignyopora Pohowsky, 1978, to name just a few.
