See text Stephanoceratidae is a family of planulate and coronate ammonites within the Stephanoceratoidea.

[1] Shells are evolute so that all whorls are exposed and have strong ribbing that bifurcates, that is splits in two, on the flanks.

Whorl sections are generally subequant; the outer rim, or venter, commonly rounded.

[1] Stephanoceratidae is derived from the Otoitidae.

Their fossils are found in upper Middle- and lower Upper Jurassic sediments.
