The shell of Euaptetoceras has an evolute, compressed, discoidal shape with a whorl section higher than wide. The inner whorls have long primary ribs while the outer whorls become smooth. The venter, which is the outer rim, is narrowly to sharply rounded and its suture is rather complex. Euaptetoceras is found in strata of Europe, Iran, and Argentina.
