See text Hoplitoidea, formerly Hoplitaceae, is a superfamily of mostly Upper Cretaceous ammonites comprising families united by a similar suture pattern with multiple similar elements that tend to decrease in size going toward the umbilicus, at the inner edge of any whorl, and which are typically in a straight line.

Sutural elements are commonly ammonitic, but in some saddles and in others both saddles and lobes are smooth and undivided.

[1] Families regarded as part now include the Engonoceratidae, Hoplitidae, Placenticeratidae, and Schloenbachiidae.

[2] Some classifications[3] however include the Forbesiceridae in place of the Engonoceratidae The older version of the Treatise[1] includes in addition to the five families already mentioned, the Pulchelliidae, Trochleiceratidae, Douvilleiceratidae, Deshayesitidae, and Leymeriellidae, which have since been reassigned.
