Siphopfenderina sp. aff. geyikensis (Solak)
Fig. 2.7-2.21 View Fig
Remarks The specimens from the Aptian of northern Spain ( Figs. 2.8-2.9, 2.11, 2.14 View Fig ) and central Iran ( Figs. 2.7, 2.10, 2.12-2.13, 2.15-2.21 View Fig ) are here treated as a single morphotype exhibiting high variability, and showing similarities to some smaller specimens of Solak (2022, pl. 1, fig. H) re-illustrated herein in Fig. 2.6 View Fig . The Turkish type-material shows generally larger dimensions, but with overlapping size-ranges to the Spanish and Iranian material. The number of whorls is three to six; transverse sections show six chambers per whorl.
Dimensions: wall thickness up to 0.065 mm ( Solak, 2022: 0.05 to 0.11 mm); test diameter up to 0.57 mm; test height up to 0.75 mm.

Remarks: Siphopfenderina ssp. is morphologically variable, a common, high-conical morphotype is treated in open nomenclature herein. It has been referred to as
Foraminifer F-66, Arenobulimina sp. , and Nezzazatinella picardi in upper Cenomanian to upper Maastrichtian shallow water carbonates of Croatia, Serbia, and Turkey (see synonymy). The central siphon is clearly visible in the specimens illustrated by Radoičić (1980) ( Fig. 2.22, 2.24 View Fig ).
