What is "saxoceras"

Saxoceras is a genus of very evolute schlotheimiid ammonoids from the Lower Jurassic of Europe and New Caledonia.

The shell of Saxoceras is discoidal bearing strong, generally straight ribs that arise on the umbilical shoulder and thicken on the middle of the venter. Similar Waehneroceras has ribs that curve forward as they approach the venter and Kammerkarites has finer ribs with secondaried. Both are also evolute schlotheimiids with all whorls exposed. Epamminites of the Arietitidae is similar from the side but has a smooth band running along the venter with a median keel.
