Terquemella sp.

Fig. 5 l (right specimens), o-r; Fig. 8 a-c

In sample S4, assembled with Russoella parthica , there is a rather small lenticular Terquemella . The size is similar to, but even smaller than the previous species, about 120- 170 P m in diameter (de) and 70 P m in thickness (da). It displays ellipsoidic cavities 35 P m long (ar) and 25 P m large (at) that are arranged radially around the surface of the little calcareous body, but in higher concentrations near the equatorial zone. The number of specimens and the size do not allow a more detailed description or an attibution to a known species.
