• Strong ribbing, often bifurcating from the umbilical seam
• Rounded to compressed whorl section
• Suture lines finely detailed, typical of Dactylioceratidae lineage

 

Notable Information:

• Lioceratoides grecoi is a rare ammonite, often poorly represented in fossil collections due to its limited distribution and rarity of exposure in accessible formations.
• Originally described from French Pliensbachian localities, it has stratigraphic importance in correlating Western European ammonite zones.
• Its sculptural ribbing and rarity make it a showpiece in ammonite fossil collections.
