Aristoceratoides

Aristoceratoides is an extinct ammonoid genus belonging to the goniatitid family Thalassoceratidae that lived during the Middle Permian. Named by Ruzhentsev, 1960, the type species is ""Thalassoceras" varicosum" Gemmellaro, 1887.
The shell of "Aristoceratoides" is globose, with ventrolateral furrows; whorls wider than high. The suture is simpler than that of its likely ancestor "Aristoceras". Suture elements are simply digitate with digits restricted to the lower half of lobes.
