Taxonomic remark From Pavia & Fernández López, 2019: The family Lissoceratidae (early Bajocian-middle Oxfordian: cf. Callomon in Donovan et al. 1981) was repeatedly treated in literature after Douvillé’s proposition. In general, it was synonymized by priority in favour of the family Haploceratidae Zittel, 1884 (e. g., Arkell 1951-1958; Arkell et al. 1957; Sturani 1971; Galácz 1980), whose typical representatives are aged to the Kimmeridgian-Hauterivian (cf. Callomon in Donovan et al. 1981) or reduced to a subfamily rank within the Haploceratidae (e.g., Fernandez-Lopez 1985; Sandoval 1986). Nevertheless, despite the morpho-structural similarities of Lissoceras Bayle, 1879 and Haploceras Zittel, 1870, the upper Oxfordian biostratigraphical gap between these two morpho-groups hinders from clarifying the phyletic relationships among the Middle and Late Jurassic haploceratoid taxa; possibly, such relationships do not exist, and the latter taxon developed analogous features deriving from a Late Jurassic haploceratoid independent of lissoceratids. Consequently, we follow Pavia’s proposition (1983, p 73; see also Zaton 2010, p. 94) that confirmed the lissoceratids at family rank after Douvillé (1885). In this systematic arrangement the subfamily Bradfordiinae (Callomon in Donovan et al. 1981) is also comprised that is represented by the late Aalenian to early Bajocian Bradfordia Buckman, (1910) with several subgenera (Sandoval 1986) or linked genera (Fernandez-Lopez 1985).
