Hercoglossidae is a family of nautilid cephalopods in the superfamily Nautilaceae.
It was established by Spath in 1927 for smooth, involute nautiloids characterized by a suture with differentiated elements, known from the Upper Jurassic to the Oligocene.
All have a whorl section that is generally rounded, except for Deltoidonatilus where in it is triangular in outline.
Cimomia, which intergrades with Eutrephoceras, is the earliest and makes its first appearance in the Upper Jurassic.
Aturoidea is the progenitor of Aturia (of the monotypic Aturidae), to which it gave rise in the Paleocene.
