Type species: Ammonites vibrayeanus d’Orbigny,1841, p. 332, pl. 96, figs. 1 e 3.
Diagnosis: highly variable, oxycone and lanceolate engonoceratid, with small, shallow umbilicus. Suture is extremely simplified consisting of rounded, narrow lobes and wide rounded saddles. Cross section is variable from compressed to slightly inflated. Venter is variable from wide to narrow trapezoidal or simply rounded and in some species ornamented by fine crenulations. Sculpture is variable, too, ranging from smooth, unornamented forms to flexuous and ventrally ornamented forms.
