The pedicle of C. chuni is long and slender and frays some distance from the umbo whereas that of C. incerta frays immediately on emergence from the foramen to give a radiating effect. The loop of C. chuni is longer and more pointed than that of C. incerta, which is short and rounded. The Meiring Naude specimens have the.
