Creniceras

Creniceras is a rather small Upper Jurassic^[1] ammonite with a shell in the range of about 1.6 cm in diameter,(about 1/2 in). The shell of Creniceras is eccentrically coiled, compressed, and generally smooth, except for a median row of cockscomb serrations on the body chamber and the possibility of blunt ribbing on the sides.
