DESCRIPTION

Test is much convex on ventral side than the dorsal side ( Figs6D View FIG ; 7C View FIG ). Diameter is between 0.65-1.146 mm and the axial thickness is 0.43-0.7 mm.The ratio of (d/t-diameter/thickness)ranges from 1.51 to 1.63. Small spheric proloculus (0.0147 -0.0265 mm in diameter) is followed by subrectangular chambers arranging in three (in a 0.65 mm diameter) and four (in a 1.04 mm diameter) regular coiled whorls ( Figs 6A View FIG ; 7A, G, O View FIG ). There are 12-13 chambers at the last whorl of grown specimens ( Figs 6A View FIG ; 7A View FIG ; Benedetti et al. 2011: figs11b, d-e). Both dorsal and ventral sides filled with pillars ( Figs 6 View FIG E-H, I-N; 7B, F-O). It has intraseptal, spiral and vertical canals (funnels) ( Figs 6A View FIG , E-N; 7A-B, F-O).

REMARKS

One specimen in Reiss & Merling (1958: pl. 3, fig. 5) resembles to G. sublobata rather than Pararotalia viennoti (Greig) owing to the mentioned generic characteristics above. Pararotalia supposed to have smooth dorsal and ventral surface with a solid and undivided umbilical plug unlike the specimens in Reiss & Merling (1958).

Four specimens from Ovčiarsko village (Žilina/ Slovakia) in ( Samuel et al. 1972; Fig. 6 View FIG K-N) defined as Rotalia sp. 8 , are identical to G. sublobata for their pseudospine, pillars and funnels.

Neorotalia alicantina Colom, 1954 View in CoL in Hottinger (2014) are not close to Neorotalia View in CoL possessing different generic characteristics (also see in Benedetti et al. [2018: 86]). However, they are very close to G. sublobata View in CoL related to the similar lateral, equatorial and axial features.

Additionally, one isolated specimen in Benedetti (2015: text-fig. 1, figs 1-3) was left out from the synonym because of the well-developed spines seeing in Ornatorotalia spinosa View in CoL ( Fig. 4 View FIG G-H). The axial sections of G. sublobata View in CoL in Samuel et al. (1972: pl. XLVII, fig. 1), Benedetti et al. (2011: fig. 11a, 13e), Sirel & Deveciler (2017: pl. 3, fig. 13), and Benedetti et al. (2018: fig. 8A) were illustrated short spine-like (pseudospine) structures rather than a canaliculate true spine.

STRATIGRAPHIC DISTRIBUTION

G. sublobata View in CoL was created first in Cuisian limestone deposits in Monte Bosco formation, Sicily-Italy and it was identified in the same stratigraphic position from Haymana-Turkey (Benedetti el al. 2011; Sirel & Deveciler 2017). However, it was previously figured under different names in Middle Eocene of Nitzana, Israel ( Reiss & Merling 1958) and West Carpatian from Slovakia ( Samuel et al. 1972). Although 27 figures in pl. 8.1 in ( Hottinger 2014) are identical to G. sublobata View in CoL , the stratigraphic position and locality of the samples were left unclear.

In this study, G. sublobata View in CoL has been found in early Lutetian (SBZ 13) together with Nummulites cf. malatyaensis View in CoL ( Fig. 8A, B View FIG ), N. praediscorbinus Schaub, 1981 View in CoL ( Fig. 8 View FIG C-H), N. praeaturicus Schaub, 1962 View in CoL ( Fig. 8 View FIG I-K), Nummulites somaliensis Nuttall & Brighton, 1931 View in CoL ( Fig. 8L View FIG ), Alveolina cf. stipes ( Fig. 9A, B View FIG ), A. stercusmuris ( Fig. 9C, D View FIG ), A. kieli ( Fig. 9E, F View FIG 1, G2), A. cf. levantina Hottinger, 1960 ( Fig. 11A, B View FIG ), Orbitolites cotentinensis Lehmann, 1961 ( Fig. 10 View FIG A-H), Pseudochrysalidina alva (Silvestri, 1939) View in CoL ( Fig. 10J, K View FIG ), Asterigerina rotula (Kaufmann, 1867) ( Fig. 11 View FIG C-E), Sphaerogypsina globulus (Reuss, 1848) View in CoL ( Fig. 11F View FIG ), Gyroidinella magna Le Calvez, 1949 View in CoL ( Fig. 11 View FIG G-I) and Fabiania cassis (Oppenheim, 1896) View in CoL ( Fig. 11J View FIG ).
