Remarks

The two specimens of Histriabairdia gen. nov. sp. 1 have different dimensions and correspond to distinct ontogenetic stages. This species is characterized by its relatively slender carapace, long and straight to convex ADB and reticulate surface. The reticulate surface of Histriabairdia gen. nov. sp. 1 is reminiscent of that of Histriabairdia gemmellaroi (Crasquin in Crasquin et al., 2018) gen. et comb. nov. from the Late Carnian of Sicily ( Crasquin et al. 2018). However, Histriabairdia gemmellaroi gen. et comb. nov. is comparatively shorter (H/L = 0.61) with ADB shorter and concave, postero-dorsal angulation less expressed at both valves and small tubercles developed in the antero-dorsal and dorsal areas of the surface. Histriabairdia gen. nov. sp. 1 is very close to Histriabairdia tuningensis ( Beher, 2004) gen. et comb. nov. from the Sinemurian, Early Jurassic, of Germany and Switzerland ( Beher 2004), as shown by its similar elongation and long, straight ADB. However, the marginal compressions along AVB and PVB are narrower, anterior maximum of curvature is located lower and the surface is punctate rather than reticulate.
