Wutinoceras(Nautiloidea) from the Setul Limestone (Ordovician) of Malaysia

Alcheringa: An Australasian Journal of Palaeontology, 1982
Wutinoceras robustum (Kobayashi & Matsumoto), previously known only from the Ordovician of north China, has been found near the base of the Setul Limestone in the Langkawi Islands, Malaysia, and strengthens the known faunal links between South East Asia and north China.

The sensory epithelium of the tentacles and the rhinophore of Nautilus pompilius L. (cephalopoda, nautiloidea)

Journal of Morphology, 2001
AbstractNine intraepithelial ciliated cell types that are presumed to be sensory cells were identified in the epithelium of the pre‐ and postocular tentacles, the digital tentacles, and the rhinophore of the juvenile tetrabranchiate cephalopod Nautilus pompilius L. The morphological diversity and specialization in distribution of the different ciliated

Large shell injuries in Middle Ordovician Orthocerida (Nautiloidea, Cephalopoda)

GFF, 2004
Abstract Sublethal injuries are described from six fragments of orthocerids, which belong to Orthoceras regulare Schlotheim, 1820, Orthoceras scabridum Angelin, 1880, Nilssonoceras nilssoni (Boll 1857) and Plagiostomoceras laevigatum (Boll 1857) from the Baltic Orthoceratite Limestone (Arenig-Llanvirn, Middle Ordovician) of Sweden, and of northern ...

New species and structures in the Narthecoceratidae (Nautiloidea, Orthocerida)

Paläontologische Zeitschrift, 1984
In the NarthecoceratidaeFlower (1958) there is variation of structures within the tubes of the endosiphuncle which may be empty, or may contain endocones or “bracket diaphragms”,Winstonocera teicherti gen. et. sp. nov. shows numerous diaphragms from which tubes extend a short distance forward.

Silurian tarphyceridDiscoceras(Cephalopoda, Nautiloidea): systematics, embryonic development and paleoecology

Journal of Paleontology, 2018
AbstractTarphycerids were diverse and abundant in Ordovician marine faunas. Beginning at the Late Ordovician extinction, the diversity of tarphycerids declined throughout the Silurian, until their extinction in the latest Silurian. Two genera survived the Late Ordovician extinction:TrocholitesConrad, 1838 (from whichOphiocerasBarrande, 1865 probably ...

Identification of a Vibrio strain producing antimicrobial agents in the excretory organs of Nautilus pompilius (Cephalopoda: Nautiloidea)

Reviews in Fish Biology and Fisheries, 2006
The aim of the present study was to identify and characterize bacteria producing antimicrobial compounds in the excretory organs of Nautilus pompilius. Culture-dependent and culture-independent complementary approaches were used for bacterial identification such as: culture on selective media, Gram staining, CARD-FISH, direct DNA extraction from host ...

Siphonal and cameral deposits inAllumettoceras and the position of the tripteroceratidae (nautiloidea)

Paläontologische Zeitschrift, 1994
New material here assigned to the Tripteroceratidae (Orthoceridae, Nautiloidea) contain cameral and siphonal deposits. Cameral and siphonal deposits are believed to have become suppressed in most later lineages of the family, producing the taxonomically ambiguous morphology seen inTripteroceras and many species ofAllumettoceras.

Nautiloidea svrchnokřídových epikontinentálních moří Evropy

2014
The post-Triassic Nautiloidea are not as popular theme within fossils cephalopods research as for example ammonites. They are not very abundant in the fossil records except some rare localities and areas, their morphology is quite conservative and due to the usually poor preservation, their determination and assigning to the species even to genera ...
