Cornuspiroidea
From Wikipedia, the free encyclopedia
Cornuspiroidea are globular, marine invertebrates belonging to the superfamily foraminiferan. The shell may be free or attached, planispiral or trochospiral, evolute or involute, spreading or discoidal[2]. The proloculus, or initial chamber, is followed by undivided spiral passage or enrolled tubular chamber, later may be irregularly coiled, unicoiled, or show zigzag growth pattern and may be distinctly chambered. The shell wall is composed of imperforate porcelaneous calcite[3], a character of the Miliolida
