Type species: Eoschistoceras turkestanicum Ruzhentsev, p. 914 [OD].[= Pintoceras PLUMMER & SCOTT, 1937, p.246, type P. postvenatum, p.246; (nom. nud., legally established by first revising authors, MILLER & FURNISH, 1958, p.257); OD (subj.)].

A:   Triangular coiling of early whorls less pronounced than in Paralegoceras.
G:   Width of umbilicus decreasing during ontogeny. Ornamentation reticulate, with umbilical ribs. Suture-line like Paralegoceras, but second umbilical lobe becoming trifurcate.

[Mapes et al., 1997, p.212: Triangular coiling in early volutions; sutural configuration, especially between umbilical shoulder and seam, provides primary diagnostic characteristic. Sutural formula = (V1V1)LU1(U2.2U2.1:U2.2)ID; U1 element typically well developed and forming a nearly symmetrical V shape.]
