Fig. 8B

Material examined

ROMANIA • 1 complete carapace; Black Sea, Romanian Continental Shelf, borehole 817LV, sample CM31B; Rhaetian, Upper Triassic; MNHN.F. F63229 • 2 LV; same locality as for preceding but samples CM31B and CM31C; Rhaetian, Upper Triassic; MNHN.F. F63348 .

Dimensions

RV: L = 973 µm; H = 554 µm; H/L = 0.57.

LV: L = 710–973 µm; H = 500–608 µm; H/L = 0.62–0.7.

Occurrence

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

Remarks

Hiatobairdia sp. 1 is distinguished from other species known from the literature and from the present assemblages by its relatively poorly expressed lateral compressions along AVB and PVB, large AB with a maximum of curvature below mid-height and a posterior maximum of curvature located very low.
