Saitoum sp. A

( Fig. 13B )

OCCURRENCE. — Lower Jurassic, lower Sinemurian of the Mersin Mélange, NW of Mersin city, southern Turkey.

DESCRIPTION

Test small with subsphaerical cephalis and a short horn. Surface of cephalis with irregularly arranged, scattered, large, subcircular pores. Horn short, needle-like, uniform in width till to the end of its preserved length. Horn not aligned to the apex of cephalis. Three feet circular in transversal section. REMARKS

This specimen differs from Saitoum triumphense ( Carter et al. 1998: 68-69, pl. 17, figs 10-11, 14-15) by possessing a very short apical horn, rare, scattered, large pores on the surface of test and short foot. It differs also from Saitoum keki ( De Wever 1982a: 192, pl. 4, figs 4-6) by having both needle-like horn and feet instead of tricarinate ones.
