Discophyllitidae are discoidal, generally evolute Phylloceratina from the Upper Triassic, derived from the Ussuritidae, in which the principal saddles of the suture have bifurcated or trifurcated endings, described as being di- or triphyllic.

Discophyllitid shells are rather similar to those of the ancestral Ussuritidae and are distinguished primarily by the more complex suture.

The Discophyllitidae provided the source for the Jurassic Phylloceratidae and Juraphyllitidae.

[2] Discophyllites and Rhacophyllites have their beginnings in the early Late Triassic.

Both are found in Europe, the Himalayas, and on Timur; Discophyllites in California and Alaska as well.
