Material examined

ROMANIA • 1 RV; Black Sea, Romanian Continental Shelf, borehole 817LV, sample CM31A; Rhaetian, Upper Triassic; MNHN.F. F63210 .

Occurrence

Romanian Continental Shelf, Black Sea, Rhaetian, Upper Triassic (this paper).

Remarks

Bairdiacypris sp. 1 differs from Bairdiacypris sp. in Forel et al. 2018 in being more elongate in lateral view with a more elongate posterior end, PB located higher and PDB concave, while it is uniformly convex in Bairdiacypris sp. in Forel et al. 2018. Bairdiacypris sp. 1 is also close to Fabalicypris triassica Bolz, 1971 from the Norian–Rhaetian of the Northern Calcareous Alps (Bolz 1971b), but it differs by its higher posterior end and straight DB. In spite of the lack of a complete carapace to observe the nature of its ventral overlap, Bairdiacypris sp. 1 has a clear tripartite dorsal margin, which precludes the attribution to Fabalicypris .
