[1][2] The following species of Cymatoceras have been described:[1] Its shell is generally subglobular, variably involute with a rounded whorl section.

[3] Paracymatoceras, coeval during the Late Jurassic and Early Cretaceous differs primarily in having a more sinuous suture.

Neocymatoceras tsukushiense from the Oligocene Ashiya Group of Japan, described by Kobayashi, 1954, has been reassigned to Cymatoceras.

[3] Fossils of Cymatoceras are found in marine strata from the Jurassic until the Oligocene (age range: from 155.7 to 23 million years ago.).

Fossils are known from several localities:[1] Mexico Antarctica, Argentina, Armenia, Azerbaijan, Chile, Colombia (Payandé, Tolima and La Guajira), France, Georgia, Germany, Greenland, India, Italy, Japan, Kazakhstan, Madagascar, Mexico, Morocco, Mozambique, Papua New Guinea, Poland, the Russian Federation, Switzerland, Tanzania, Turkmenistan, Ukraine, the United Kingdom, United States (California, New Mexico, Texas).
