Origin and evolutionary history of Anglonautilus (Nautilida, Cymatoceratidae) and a new species from the lower Aptian of Spain

Autor: Michael W. Maisch, Angélique Salfinger-Maisch, Jens Lehmann, Cyril Baudouin

Publikováno v: Cretaceous Research. 72:66-80

The cymatoceratid nautilid genus Anglonautilus is distinguished from most other post-Triassic nautiloids by the occurrence of pronounced fold-like undulating ribs on the phragmocone and early body chamber. Anglonautilus praeundulatus n. sp. is descri

Autor: Cyril Baudouin, Emmanuel Penagé, Gérard Delanoy, Marc Boselli

Publikováno v: Carnets de géologie (Notebooks on geology). 16:369-381

New investigations in the Vocontian Lower Aptian deposits resulted in the discovery of very rare specimens of heteromorphic ammonites whose specific morphological and ornamental features have led to the erection of Ivaldiceras gen. nov. Represented b
