, a rostrum (or telum) is undocumented, which was interpreted by Jeletzky (1966) as primary absence. If this is the case, then they cannot be assigned to the Aulacoceratida, an approach that was already proposed by Mariotti and Pignatti (1992, 1993) and by the Treatise on Invertebrate Palaeontology (Mariotti et al., 2021). The absence of a rostrum may be taken as evidence to classify these taxa within the Phragmoteuthida, but representatives of this order are generally characterised by much larger apical angles and possess a typical three-lobed proostracum (Fuchs & Donovan, 2018). In contrast,
