Mesozoic

• Cretaceous
  • Upper Cretaceous
    • Coniacian

The Brezno Formation (lower Coniacian) of the Bohemian Cretaceous contains several Stromboidea

• Perissoptera reussi (Geinitz, 1842) (bottom, left)
• Perissoptera megaloptera (Reuss, 1845) (top, left)
• Latiala papilionacea (top, right)
• Latiala coarctata (bottom, right)
• Dimorphosoma substenoptera (bottom, middle)

The Strehlen-Formation belongs to the lower Coniacian, upper Turonian, upper Cretaceous
