Perisphinctidae

See text Perisphinctidae is a family of Middle and Upper Jurassic discoidal ammonites in the order Ammonitida.

They have a shell morphology that is mostly evolute, typically with biplicate, simple, or triplicate ribbing.

The Treatise on Invertebrate Paleontology (Part L, 1957) includes the subfamilies Leptosphinctinae, Zigzagiceratinae, Pseudoperisphincinae, Perisphinctinae, Aataxioceratinae, Pictoniinae, Aulocostephaninae, Virgostephaninae, Dorsoplanitinae, and Virgatitinae in the Perisphictidae.

[1] Donavan et al [2] also recognizes the subfamilies Leptosphinctinae, Zigzagiceratinae, Pseudoperisphincinae, and Perisphinctinae but leaves out the others, adding instead the Epipletoceratinae and Idoceratinae.

Epipeltoceratinae is based on Epipletoceras, a genus in the Aspidoceratidae in the Treatise, (subfamily Peltoceratinae).
