1 Fossilium Catalogus I: Animalia. Pars 152. Lower Cretaceous Ammonites VII: Hoplitoidea & Engonoceratoidea (2014) © Backhuys Publishers, Margraf Publishers ISBN 978-3-8236-1678-8/ revision 6 On the revision by Fischer & Gauthier et al. (2006) of d’Orbigny’s Paléontologie française volume IV. Note 6: Hoplitoidea & Engonoceratoidea by JAAP KLEIN (April 2021) In the seventh part of Lower Cretaceous Ammonites Hoplitoidea & Engonoceratoidea (2014) the revision of d’ORBIGNY’s Paléontologie française volume IV: Céphalopodes crétacés by FISCHER & GAUTHIER et al. (2006) has been taken into account. But some corrections in the Catalogus are necessary. We cover all the ammonites of this superfamily treated by D'ORBIGNY under 16 numbers and revised by various authors in the ‘Révision critique de la Paléontologie française volume IV: Céphalopodes’. We consider in this note also the website of the ‘Muséum national d’Histoire naturelle Paris (MNHN)’, which provides detailed information about these species, with pictures and with nomenclatural remarks by JEAN-MICHEL PACAUD, Curator Assistant for the Fossil Invertebrate Collection. Superfamily Hoplitoidea No. 31. Ammonites Renauxianus – Pleurohoplites renauxianus (D’ORBIGNY, 1840) D’ORBIGNY (1840), 114 writes that RÉNAUX, to whom he owes the communication of this species, found it in Bédoin, south of the Mont Ventoux (Vaucluse). He depicts this specimen from the RÉNAUX Collection on his pl. 27, fig. 1, 2. A holotype by monotypy. On page 359 he reports that he has seen quite a few specimens of this species found by RAULIN in Montblainville (Meuse). KENNEDY & JUIGNET in FISCHER & GAUTHIER et al. (2006), p. 29 write that the holotype could not be found in RÉNAUX Collection, which is now being preserved at the ‘Laboratoire de Paléontologie des Invertébrés. Université des Sciences et Techniques de Montpellier (Hérault)’. On the website of the MNHN 9 specimens (under 6 numbers) of Ammonites renauxianus are reported from Montblainville (Meuse). These are probably RAULIN’s specimens as KENNEDY & JUIGNET (2006) notice. According to them these specimens are Hoplitidae, too badly preserved to serve as type. No. 95. Ammonites interruptus BRUGUIÈRE, 1789 1 - Amedroites baylei (SPATH, 1925), Amedroites paronae (SPATH, 1925), Hoplites dentatus densicostatus SPATH, 1925, Hoplites dentatus sulcatus SEITZ, 1930, Hoplites dentatus robustus SPATH, 1925. D’ORBIGNY (1841), p. 215 writes that he and many others found this species in many places. He depicts under the name Ammonites interruptus 6 specimens on 2 plates without mentioning the collectors and locations. 1 Nomen dubium.
