TheInfoList



OR:

''Saxoceras'' is a genus of very evolute schlotheimiid ammonoids from the Lower Jurassic. The shell of ''Saxoceras'' is discoidal, bearing strong, generally straight ribs that arise on the umbilical shoulder and thicken in the middle of the venter. Similar '' Waehneroceras'' has ribs that curve forward as they approach the venter, and '' Kammerkarites'' has finer ribs with secondaries. 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.
