Material examined

ROMANIA • 1 complete carapace; Black Sea , Romanian Continental Shelf , borehole 817LV, sample CM31A; Rhaetian, Upper Triassic; MNHN.F. F63266 View Materials • 1 complete carapace; same locality as for preceding but sample CM31C; Rhaetian, Upper Triassic; MNHN.F.

Dimensions

RV: L = 333–482 µm; H = 162–243 µm; H/L = 0.46–0.49.

LV: L = 333–482 µm; H = 162–243 µm; H/L = 0.48–0.5.

Occurrence

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

Remarks

The present species is close to Aglaiocypris ? sp. from the Ladinian, Middle Triassic, of Spain ( Kozur et al. 1974). This species is morphologically similar to Fabalicypris ? sp. A in Ainsworth 1990 from the Hettangian, Early Jurassic, from Ireland ( Ainsworth 1990), but the carapace of the present species is thinner, with H max located more anteriorly, shorter and more rounded ADB, and AB more rounded and less bairdiid. These characters are closer to those of Aglaiocypris as described in Kozur et al. (1974).
