Material examined

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

Dimensions

L = 821 µm; H = 311 µm; H/L = 0.38.

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 .
