Aplococeras is an evolute discoidal ceratitid ammonite from the Middle Triassic Ladinian stage, found in southern Europe and Nevada. Whorl sides are convex, converging on a rounded venter (the outer rim), and are ornamented with slightly flexuous umbilical ribs that disappear outwardly, towards the venter. The suture has two lateral lobes (on either side).
