Plant and Fungal Species Descriptions

The occurrence of the nautiloid genus Anglonautilus Spath in France was limited to the report of Anglonautilus dorsoplicatus (Wiedmann) from the Albian of Escragnolles (Alpes-Maritimes) and Anglonautilus sp. from the Aptian of Les Ferres (Alpes-Maritimes). Here we document the presence of the successive species Anglonautilus praeundulatus Lehmann et al., Anglonautilus undulatus (Sowerby) and Anglonautilus dorsoplicatus (Wiedmann) from the Cretaceous of France. The stratigraphic range of Anglonautilus Spath, hitherto unknown before Aptian times is extended downward to the Hauterivian. The Hauterivian species Nautilus begudensis Kilian & Reboul, sometimes assigned to the genus Anglonautilus Spath, is revised and re-assigned to the genus Cymatoceras Hyatt.
