Terquemella globularis Elliott 1956

Fig. 5 u-v; Fig. 9 a-b

Another Terquemella (sample T13) also occurs in the Maatrichitian, which is moderately large, most likely subspherical and more or less irregular. The diameter (de) is 330 P m with spherical cysts of 40 P m in thickness (at). 14 cysts can be counted in transversal section. Its general shape and size allow relating such taxon with Terquemella bosnae Radoičić (1992) , but this latter species displays a greater number of cysts. As to size, shape and number of cysts, these calcified bodies seem more appropriately assigned to Terquemella globularis from the Paleocene of Iraq.
