Zaphriphyllum

Sutherland first described it in 1954 from a rock containing a fauna of the Middle Mississippian age in the Northern territory of Canada.^[3] Sutherland proposed the genus Zaphriphyllum for those zaphrentids which still possess a trochoid shape and pronounced cardinal fossula and consistently have dissepiments. These forms usually also show a tendency toward a radial arrangement of the septa in the immediate area of the cardinal fossula. Zaphriphyllum closely resembles Amplexizaphrentis Vaughan; except that, as Sutherland (personal communication) has pointed out, the latter is characterized by the absence, or very sparse and discontinuous development, of dissepiments.^{[citation needed]}
