All members of the Ammonoidea should share a homologous developmental mode), or have been excluded outright as having formed differently. Tanabe (1989), for example, views embryonic shells of the Mesozoic ammonoids as having formed by a non-accretionary mode. However, like Erben, Tanabe interprets the transverse lirae (or ornament) on the embryonic shells of Paleozoic ammonoids as an indication of accretionary growth. In our examination of the embryonic ornament of Paleozoic ammonoids we seek a way to differentiate between ornament formed by accretionary versus non-accretionary modes.
