Abstract
Conulariids from the Lower Ordovician of the southern Montagne Noire, France
Highlights
The Tremadocian–Floian (Lower Ordovician) Saint-Chinian, La Maurerie, and Landeyran formations of the southern Montagne Noire (France) collectively contain at least two species of conulariids, namely Archaeoconularia cf. insignis and Conularia azaisi, the latter designated as the type species of the new genus, Galliconularia
Archaeoconularia insignis may occur in the Lower Ordovician Fezouata Shale of southern Morocco, and an indeterminate species of this genus probably occurs in the Lower Ordovician Tonggao Formation of South China
Galliconularia azaisi differs from all other conulariids in having a raised facial midline and very fine, trochoidal transverse ribs which cross the midline ridge without interruption or diminution
