2025 accepted Pleuroceras solare form solare (Phillips) ; Meister et al., pl. 85, figs. 3–5, 8–11, pl. 86, fig. 1–3

Material: Tree specimens (Ge 33503–33505) and twenty fragments.

Description: Typical platycone evolute Pleuroceras with regular, subradiate, simple, rather rigid and acute ribs, which are strongly arched forward on the latero-ventral part. Tese disappear before reaching the base of a well-developed crenulated keel. Te whorl section is subrectangular, weakly compressed with rather flat subparallel flanks. Tiny tubercles can be seen on the ribs below the latero-ventral edge in few specimens.

Remarks: Some specimens show a transitional morphology between P. transiens (Frentzen, 1937) and P. solare

( Fig. 3K View Fig ). Tis concerns mainly the ventral part which is not flat or sulcate as in typical P. solare , but arched, as in P. transiens . However, the keel is rather smooth, the crenulation is not as pronounced as in P. transiens . Te ribs are straight and sharp, curved strongly forward at the latero-ventral edge. Two fragmentary specimens ( Fig. 3I View Fig ) show typical ornamentation of P. solare but with flanks clearly converging towards venter and tubercles on ribs also in larger D, the characteristics of P. solare var. trapezoidiforme (Maubeuge, 1951) .

Occurrence: Tis species characterises the upper part of the Apyrenum Subzone (Meister, 1988) . It is well distributed in NW Europe and in the Western and also Mediterranean Tethys (Upper Austroalpine units in Austria, Western Carpathians in Slovakia and the Czech Republic, Eastern Carpathians and Bihor in Romania, Southern Calcareous Alps, UMB and Sicily in Italy, Betics in Spain, High Atlas in Morocco and in western Algeria).
