Andreiella rajkae Bucur, 2014

( Fig. 5 e )

Andreiella rajkae was recently described by Bucur (2014) from Upper Barremian – lowermost Aptian (lower Bedoulian) limestones in the Hăghimaş Mountains (Eastern Carpathians, Romania). It is characterized by a cylindrical thallus with a narrow main stem and two orders of laterals. The first order laterals, large and clubshaped, gradually broaden from the proximal to the distal part where they slightly narrow towards the exterior. The secondary laterals are short and vesiculiform to ovoid in shape. Calcification forms an irregular sleeve around the distal end of the primary laterals, embedding the secondary ones.

A single specimen was identified in the studied samples from Trbušnica ( Fig. 5 e ), however it is very representative for the species. Until this study, A. rajkae has been identified in only three sites: Mount Rujen (Vardar zone, Macedonia) (Radoičić, 2002), Bicaz Gorges (Hăghimaş Mountains, Eastern Carpathians, Romania) ( Bucur & Săsăran, 2011; Bucur, 2014), and Munella Platform ( Albania) (Schlagintweit, unpublished; Bucur, 2014). Thus, Trbušnica represents the fourth location for this species.

Dimensions (mm): D = 2.60; d = 0.60; p (distal) = 0.30; p’ = 0.07.
