Family EOENDOTHYRANOPSIDAE Reitlinger View in CoL in Rauzer-Chernousova et al., 1996
Test involute, almost planispiral, with numerous quadratic chambers, truncated septa, no sutures, and a carinate to rounded periphery. Pseudochomata, often associated with a terminal hook. Wall brownish with calcareous agglutinate. Early–late Visean.
Remark: The wall microstructure of Ninella is unfortunately poorly known; either microgranular or granular. Consequently and hypothetically, we reattached Ninella to the Eoendothyranopsidae . Ninella staffelliformis (Chernysheva, 1948) is relatively similar to Eoendothyranopsis , whereas Ninellla asiatica is more comparable, morphologically, to a big dainellid; furthermore, N. extremus Ponomaryova, 2009 is most probably a dainellid Vissarionovella rather than a true Ninella . The emendated description of Ninella by Reitlinger in Rauzer-Chernousova et al. (1996) is here followed.
Composition: Eoendothyranopsis Reitlinger & Rostovzeva, 1966 ; Ninella Malakhova, 1975 ; Skippella Mamet, 1974 .
