Tozerium orbuklukeliense Tekin, n. sp. (Fig. 9 P-R) urn:lsid:zoobank.org:act: D0FD13C2-4B21-4640-9815-2297D5FFBEB3 HOLOTYPE. — Sample Orbuk-32, HU.JMB.0142 (Fig. 9P). TYPE LOCALITY. — Orbuklukeli section, Mersin Mélange, NW of Mersin city, southern Turkey. ETYMOLOGY. — Named after its type locality. OCCURRENCE. — Lower Jurassic, lower Sinemurian of the Orbuklukeli section, Mersin Mélange, NW of Mersin city, southern Turkey. PARATYPES. — HU.JMB.0143 (Fig. 9Q), HU.JMB.0144 (Fig. 9R). DIMENSIONS (based on three specimens, in µm). — Maximum diameter of cortical shell: 110-128 (holotype: 110, average: 116); Maximum length of spine: 85-114 (holotype: 100, average: 99.6). DESCRIPTION Cortical shell small to medium-sized with four strong spines. Cortical shell sphaerical to subsphaerical composed of small to medium-sized polygonal (mainly trigonal to tetragonal) pore frames and large, subcircular pores at pore frame vertices. Spines prominent, robust, needle-like, subcircular in transversal section, decreasing in width gradually to its end. Length of spines approximately equal to diameter of cortical shell. REMARKS This species differs from Tozerium nascens (Carter et al. 1998: 44, pl. 1, figs 1, 7, 8, 13, 14, 18, 23, 24) by having a sphaerical, smaller cortical shell with smaller pore frames, large nodes at pore frame vertices and prominent, robust and longer primary spines.
