Citrella? carniana Forel in Forel, Tekin, Okuyucu, Bedi, Tuncer & Crasquin, 2019a: 39, figs 20K-O.

Cytheropteron ? cf. triassica – Kozur in Kristan-Tollmann et al. 1991a: 201, pl. 4, fig. 4.

EXAMINED MATERIAL. — One right valve.

OCCURRENCE. — Middle Carnian, Late Triassic, Transdanubian Midmountains, Western Hungary (Kristan-Tollmann et al. 1991a); Tetraporobrachia haeckeli radiolarian Zone, Julian, Carnian, Late Triassic, Mersin Mélange, southern Turkey, Huğlu Tuffite (Forel et al. 2019a); Nicoraella ? budaensis conodont zone, late Julian-?earliest Tuvalian, Carnian, Late Triassic, sample BE2 ( Fig. 3 View FIG ), Belca section, ‘Raibl Beds’, Karavanke Mountains, Slovenia (this work).

DIMENSIONS. — L = 345 µm, H = 223 µm (BE2 [GeoZS6177]).

DISCUSSION

Citrella? carniana has only been found in sample BE2 of Belca section, where it is rare ( Fig. 3 View FIG ). This species is until now only known from the Carnian stage. The specimens from the type locality in Turkey range from 250 to 400 µm in length and from 169 to 238 µm in height (Forel et al. 2019a). The specimen obtained from the Belca section might therefore not be an adult but rather a late juvenile.
