Remarks on the genera Ophthalmidium and Palaeomiliolina (Foraminiferida)
Olga Pazdro
In the light of ambiguities in interpretation of some genera of Miliolidae by various authors a precise definition of Ophthalmidium Kübler & Zwingli, 1870, and Palaeomiliolina Loeblich & Tappan, 1964 is given on the basis of Jurassic materials from Poland, other countries and literature. Structure of tests and microstructure of walls were investigated. Enlarged photographs in polarized light are presented. Close affinity was stated of the genera in question and both were assigned to one family. A stratigraphic table of species noted from the Triassic and Jurassic is presented and
their generic affiliation corrected.
