KOCAELIA GEN. N. (FAMILY BEYRICHITIDAE) FROM MIDDLE ANISIAN
Rivista Italiana di Paleontologia e Stratigrafia, 2018 The new genus Kocaelia, with Aspidites toulai (Arthaber) as a type species, is here described. Based on the involute and compressed shape, occurrence of straight to slightly sinuous ribs and subammonitic suture in mature individuals the genus Kocaelia is

Analysis of septal spacing and septal crowding in Devonian and Carboniferous ammonoids
Swiss Journal of Palaeontology, 2021 Septal crowding is widely known as a sign of maturity in conchs of ammonoids and nautiloids. However, reduced septal spacing may also occur as a consequence of adverse ecological conditions. Here, we address the question how septal spacing varied through

VI.—On Cretaceous Ammonoidea from Angola, collected [PDF]
Transactions of the Royal Society of Edinburgh, 1922 The Ammonoids described in the present paper were placed first of all, for study, in the hands of Mr J. M. Wordie, whose departure, however, as geologist with Sir E. Shackleton's Antarctic Expedition prevented the completion of the work. A preliminary list of identifications by Mr Wordie included a number of forms of “Schloenbachia” especially “S ...

Phylloceratina ammonoids in the Iberian Basin during the Middle Jurassic: a model of biogeographical and taphonomic dispersal related to relative sea-level changes [PDF]
, 1996 Phylloceratina and Lytoceratina ammonoids in the Middle Jurassic of the Iberian Chain (E. Spain) represent less than 1% of the whole of Ammonoidea. There are two intervals, however, in which their occurrence is remarkably constant: within the Upper ...
