Representatives of the Prodromitidae are characterized by relatively large (up to 150 mm diameter) lenticular conchs with acute ventral keels and complex multilobate sutural configurations. The systematic position of the Prodromitidae has been the subject of considerable speculation (see Work et al., 1988 for review). The nominate genus, ProdromitesSmith and Weller, 1901 (type species, Goniatites gorbyiMiller, 1891), is not typical and represents the culmination of the lineage, showing characters which have led authors to refer it to both the Gephuroceratina (Ruzhencev, 1960, 1962, 1965; Bogoslovsky, 1969; Ruzhencev and Bogoslovskaya, 1978) and...
