Abstract:
Nautiloids are a charismatic group of marine molluscs best known for their rich fossil record, but today they are restricted to a handful of species in the family Nautilidae from around the Coral Triangle. Recent genetic work has shown a disconnect between traditional species, originally defined on shell characters, but now with new findings from genetic structure of various Nautilus populations. Here, three new species of Nautilus from the Coral Sea and South Pacific region are formally named using observations of shell and soft anatomical data augmented by genetic information: N. samoaensissp. nov. (from American Samoa), N. vitiensissp. nov. (from Fiji), and N. vanuatuensissp. nov. (from Vanuatu). The formal naming of these three species is timely considering the new and recently published information on genetic structure, geographic occurrence, and new morphological characters, including color patterns of shell and soft part morphology of hood, and will aid in managing these possibly endangered animals. As recently proposed from genetic analyses, there is a strong geographic component affecting taxonomy, with the new species coming from larger island groups that are separated by at least 200 km of deep water (greater than 800 m) from other Nautilus populations and potential habitats. Nautilid shells implode at depths greater than 800 m and depth therefore acts as a biogeographical barrier separating these species. This isolation, coupled with the unique, endemic species in each locale, are important considerations for the conservation management of the extant Nautilus species and populations.

Abstract:
Abstract Substantial numbers of the nautilid Cenoceras occur in a stratigraphically limited horizon within the upper part of the Lower Jurassic (Sinemurian Stage) Blue Lias Formation at Watchet on the West Somerset Coast (United Kingdom). Individual nautilid conchs are associated with clusters of encrusting organisms (sclerobionts) forming ‘islands’ that may have been raised slightly above the surrounding substrate. Despite the relatively large numbers of nautilid conchs involved, detailed investigation of their preservation suggests that their accumulation reflects a reduction in sedimentation rates rather than an influx of empty conches or moribund animals. Throughout those horizons in which nautilids are present in relative abundance, the remains of ammonites are subordinate or rare. The reason for this unclear, and preferential dissolution of ammonite conchs during their burial does seem to provide a satisfactory solution to the problem.

Abstract:
Nautilus is the only surviving genus whose members were numerous and widely dispersed in the oceans throughout the Jurassic and Miocene times. It represents the only living member from the Family Nautilidae and is often considered as a living fossil. Nautilus is found with high biodiversity in Ambon, Indonesia, and were in special cases even found in Bangka Belitung, far from their original habitat. This study aimed to understand the historical component of the habitat and distribution of Nautilus in Bangka Belitung and to determine the depth, temperature, current, and environmental heterogeneity relate to Nautilus. Nautilus samples were found in Bangka Belitung Seas nearby a crack region at 50–75 m deep while the optimal depth of the Nautilus was 150–300 m, depending on the local area. The locations in the Bangka Belitung Seas where Nautilus found have sea surface temperatures between 30-31°C and 27-28°C during the East Monsoon and the West Monsoon respectivelly. The implications of temperature as a limiting factor are fairly significant, as it restricts the upper limit of the living habitat to predictable depths, which vary both geographically and seasonally during the West Monsoon when surface temperatures approach habitable levels. Sea currents at the Bangka Belitung Seas move at 0–0.6 m.s-1 during the East Monsoon and speed up near the North Natuna Sea. During the West Monsoon, currents predominantly flow from the Natuna Sea to the Java Sea at 0–0.5 m.s-1. Large-scale deep-water currents and the effects of smaller currents on scent dispersal influence the directional movements of Nautilus.

Abstract:
This paper describes new nautilids from the Shakhtau Asselian–Sakmarian reef complex. Their place in the nautilid system, which is still far from being completely understood, is discussed. Two species of two genera: Omorphoceras igori gen. et sp. nov. and Stenopoceras (Leptodomatoceras) bashkiricum subgen. et sp. nov. are assigned to the subfamily Domatoceratinae Miller et Youngquist, 1949, family Grypoceratidae Hyatt, 1900. The third, Foveroceras magnum gen. et sp. nov., is included in the exotic family Permoceratidae Miller et Collinson, 1953, which was previously considered monotypic and was known only from the Early Permian of Timor Island. The classification of the family Grypoceratidae is discussed, and the validity of the subfamily Domatoceratinae is questioned. The assumed phylogenetic relationship between the families Grypoceratidae and Permoceratidae is confirmed.

Abstract:
ABSTRACT The fluvial and deltaic deposits formerly described as the Wadi ad Dawasir “delta” have been reinterpreted on the basis of a new examination of biostratigraphic data, notably ammonites and brachiopods studied by the authors and nautilids studied by the late H. Tintant (the term “delta” as used in other documents is shown here in quotes because of insufficient evidence to confirm it as a true delta). Direct dating of the fluvial and deltaic deposits is not possible in the absence of age-indicative fossils, but the entire “delta” complex can be placed in the Lower Bathonian on the basis of Bathonian ammonite and brachiopod faunas found in underlying strata, and a Lower Bathonian nautilid found in the uppermost proximal beds. An Early Bathonian age of the “delta” revises the Middle Callovian age assumed by previous authors based on their admittedly lithostratigraphic correlation with marine strata of the Dhruma Formation. The Early Bathonian age is consistent with the alternative interpretation, which correlates the “delta” with the discontinuity in the marine sequence between units D5 and D6 of the Dhruma Formation, with a stratigraphic gap of Lower (in part) and Middle Bathonian. The nautilids and brachiopods from above and “apparently at the front” of the “delta” together with the ammonites, nautilids, brachiopods and calcareous nannoplankton from units D6 and D7, indicate a complete sequence from the Upper Bathonian (unit D6) to Upper Callovian (units T2 and T3 of the Tuwaiq Mountain Limestone) with transgressive overlap of the “delta” during Middle and Late Callovian. The Wadi ad Dawasir “delta” is here interpreted as resulting from a limited relative sea-level fall, causing progradation of a shelf deltaic wedge over the downlap surface associated with the D5–D6 discontinuity. Similar deltaic or/and paralic deposits have been described in the Lower Bathonian of northern Sinai, presumably of the same age, Negev and in the Bathonian of southern Tunisia, which indicate an event of wide extent (eustatic, climatic or tectonic) along the northern Gondwanan margin.

Full text
Abstract:
The atypical Late Cretaceous nautilid Epicymatoceras vaelsense (Binkhorst van den Binkhorst, 1862) is described and illustrated on the basis of three specimens from the Maastrichtian white chalk of Denmark. One of these is probably from the lower/upper Maastrichtian boundary interval at Frejlev, while the other two originate from the uppermost Maastrichtian chalk as exposed in the Dania quarry; both localities are in Jylland, northern Denmark. These are first reports of E. vaelsense from Denmark; the species has previously been recorded from the uppermost Campanian and lower Maastrichtian of the Netherlands, Belgium, northern Germany and Poland. The presence of E. vaelsense in the topmost Maastrichtian white chalk in the Dania quarry is considered the youngest record of Epicymatoceras known to date, suggesting the persistence of the genus until the end of the Cretaceous. The diameter of the embryonic conch of the Danish E. vaelsense may be estimated at c. 30 mm, based on an individual from the Dania quarry, confirming earlier observations that the species possessed one of the largest embryonic conchs amongst Late Cretaceous nautilids.

Abstract:
Morphometric analyses of shell morphology in the Pennsylvanian nautiloid Metacoceras mcchesneyi Murphy, 1970 (Cephalopoda, Mollusca) recovered from coal mines in Madison Township, Columbiana County, Ohio, USA, reveal the ontogenetic change from hatching to maturity as well as intra-specific variation of shell morphology. The shell shape of M. mcchesneyi has isometric relationships, and the umbilicus diameter between umbilical shoulders has a positive allometric relationship with shell diameter. These show that the relative whorl shape was constant through the ontogeny, but the umbilicus became relatively broader with growth. The siphuncle position moved from a ventro-central position toward the center with growth until 420° of the total rotational angle had been attained. A constriction was recognized on the early whorl at 9.5 mm in shell diameter, and the interval angles of succeeding septa were changed at the 5th septum, indicating that hatching occurred at this diameter. The ventral apertural wall, the disappearance of ornamentation toward the last preserved aperture, and the last whorl separating from the previous whorl indicate that M. mcchesneyi attained maturity at ca. 70 mm in shell diameter. Most characteristics of shell morphology in M. mcchesneyi (the relative shell shape and ornamentation through ontogeny) are comparable to those in modern and younger fossil nautilids, irrespective of taxonomy and age, supporting the conclusion that evolutionary rates of shell morphology are conservative in nautilid history.

Abstract:
L'examen des différentes étapes du développement ontogénétique des Nautilida post-triasiques, permet de préciser la signification des modifications morphologiques et dimensionnelles de la coquille, des stades embryonnaires précoces jusqu'a la maturité sexuelle. La synchronisation entre le cloisonnement et la croissance aperturale de la coquille est mise en évidence, et les facteurs internes et externes régissant l'évolution ontogénétique du rythme de cloisonnement sont analysés. Leur morphologie relativement conservatrice reflète une évolution canalisée par d'étroites contraintes morphofonctionnelles liées a leur mode de propulsion basé sur la contraction de puissants muscles, et à un mode de vie nectobenthique à tous les stades du développement post-embryonnaire. Leur répartition répond à des facteurs écologiques stricts (profondeur, variations eustatiques du niveau marin. . . ). Le caractère sténotypique des lieux de ponte explique leur exclusion du domaine boréal. La capacité pour les Nautilida d'évoluer à la fois au niveau des plates-formes et le long de la pente continentale, leur mode de vie nectobenthique dès l'éclosion et leur mode de nutrition probablement nécrophage opportuniste, constituent sans doute les facteurs majeurs expliquant leur survie à la limite Crétacé-Tertiaire. La distribution paléobiogéographique cosmopolite du genre tertiaire Aturia BRONN, 1838, résulte en grande partie d'un fréquent et long transport post-mortem de sa coquille. Cette fréquence anormalement élevée s'explique par la morphologie singulière de son siphon. Le caractère monophylétique des Nautilida post-triasiques est remis en cause. Le genre Cenoceras HYATT, 1883, qui selon cette conception aurait assuré la pérennité du groupe à la limite Trias-Lias, est en fait un regroupement artificiel, révisé par la réhabilitation des genres Ophionautilus SPATH, 1927, et Digonioceras HYATT, 1894, et la différenciation des espèces du groupe de Gen. Nov. ? A austriacus HAUER, 1856 et de Gen. Nov. ? B araris DUMORTIER, 1869. Le genre Germanonautilus MOJSISOVICS, 1902, classiquement considéré comme éteint au Trias supérieur, paraît survivre au moins jusqu'au Carixien. Quatre à cinq genres triasiques appartenant à des taxons supragénériques différents, ont sans doute traversé la limite Trias-Lias.

Abstract:
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 level is often complicated. Exceptional are taxa with very specific morphology and short stratigraphic and endemic occurrence, which are even suitable for biostratigraphic interpretations. Problematic is also the often poor taxonomical representation of the type material and revision of many taxa is needed. Still nautilids are often represented by reasonable amount in the paleontological collections of natural history museums due to the long history of fossils collecting. Also the scientific literature has been dedicating at least some space to this group since 19 century. The aim of this study is to create an overview about the post- Triassic, especially Upper Cretaceous nautiolidea in the European region of epicontinental seas and prepare a good basement for extensive study of this group. Due to this aim the study is primarily focused on determination of morphological features and also problematic with their interpretation according to the variable...
