These cephalopods existed in the Jurassic period, during Toarcian age in the Falciferum zone and possibly only in Exaratum subzone. Its fossils were found in Canada, Morocco, Algeria and Italy[1][2][3] DescriptionModeratelly involute, keeled, tectiform, sub-ogival shell with bold, regularly bifurcating ribs. It is similar to Pseudolioceras, but is more evolute and differs from other Harpoceratinae by having bifurcating ribs.[1][4] References1. ^1 2 M. K. Howarth 2013.
