| Scherzinger A., Parent H., Schweigert G. (2015) A new species of the ammonite genus Neochetoceras Spath (Oppeliidae) from the Hybonotum Zone (Lower Tithonian) of Southern Germany, with comments on the phylogeny of the genus // Boletín del Instituto de Fisiografía y Geología, Vol.85. (in press)
http://www.fceia.unr.edu.ar/fisiografia/Volumen85/Scherzinger_etal.pdf
We here introduce a new species of the Submediterranean oppeliid genus, Neochetoceras, N. mohri n.sp. represented by both macro- and microconchs. N. mohri n. sp. is better recorded than any other nominal species of this genus and links the early representatives of the lineage with the type species, N. steraspis (Oppel). Possible phyletic ancestors and the biogeographic distribution are briefly discussed. The Neochetoceras succession in the uppermost Kimmeridgian (Beckeri Zone) to Lower Tithonian (Hybonotum and Mucronatum zones) is summarized.
Middle Jurassic - Lower Cretaceous ammonites & aptychi
