Description
Fig. 3 Ticinoteuthis chuchichaeschtli gen. et sp. nov. from the Besano Formation (Middle Triassic) of the Monte San Giorgio, Ticino, Switzerland and a co-occurring orthoceratoid for taphonomic comparison. A–D PIMUZ 39491, holotype, bed 112 A Lateral view. B Adapical view of preserved phragmocone, exposing the ventral position of the siphuncle. C Lateral view of preserved phragmocone, exposing faint traces of inclined septa. D Lateral view of adapical external mould, exposing potential traces of septa. E–G PIMUZ 39493, T. chuchichaeschtli gen. et sp. nov., bed 94. E Lateral view. F Enlarged view of longitudinal ribs. G Lateral view of counterpart. H PIMUZ 39060, bed 94, likely orthoceratoid with similar longitudinal ribs. Note the irregularity in these structures, suggesting that these represent a taphonomic artefact. Abbreviations: si = siphuncle, se = septa
