Abstract. The benthonic foraminiferid Osangularia schloenbachi (Reuss, 1863) is an established index taxon for Albian to Aptian age sediments worldwide. It is a very useful marker species commonly encountered in cuttings sampled from offshore boreholes on the north-west European continental shelf. However, despite its biostratigraphical utility there is no known holotype for this species. This short article rectifies this taxonomic point of order by erecting a neotype for the species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
