The mitrocystitid mitrate Vizcainocarpus dentiger gen. et sp. nov. originates from the Lower Arenig of the Montagne Noire, France. Its distinctive features are two dorsal areas of polyplated integument, thorn-like projections on the postero-ventral head plates and a leftward-opening mouth. A preliminary cladistic analysis shows that V. dentiger is more derived than Chinianocarpos thorali and is the most primitive mitrocystitid with a differentiated centro-dorsal plate D12 and with the upper lip plate n rigidly incorporated in the skeleton.
