- Аннотация: The evolution of superfamily Palaeotextularioidea (Foraminifera) is considered. Several stages in the development of palaeotextularioids in the Early Carboniferous were recognized: 1. the emergence of biserial forms with a single-layered and double-layered wall and a simple aperture; 2. complication of the aperture structure – there is the conversion from a simple to a cribrate aperture in the last chambers; 3. the appearance of bimorph forms with a complicated cribrate aperture in the uniserial last part of the test.
