The natural history of the nautilid genus Nautilus, composed of a controversial number of extinct and extant species, has been the subject of scientific scrutiny for centuries. While a great research effort last...
Spath (1931) described five genera namely Sivajiceras Spath, Obtusicostites Buckman, Hubertoceras Spath, Kinkeliniceras Buckman and Cutchisphinctes Spath from the Upper Bathonian and entire Callovian of Kutch, we...
Differently-shaped ammonoid shells present varied hydrodynamic properties, but the relevance of shell shape to ammonoid paleoecology is unclear. To examine trends in ammonoid shell shape that relate to hydrody...
Plesioteuthis is a coleoid rather well known from the classical Fossillagerstätten of southern Germany (Solnhofen–Eichstätt region, Nusplingen). Here, we present two new specimens that di...
In the cephalopod subclass Coleoidea, several homology problems exist, mainly owing to unsolved phylogenetic relationships between decabrachian orders. The present contribution reviews the “similarity” of the ...
In September 2014, the 9th International Symposium Cephalopods—Present and Past was held at the Universitz of Zurich in combination with the 5th International Coleoid Symposium. Here, give a short account of t...
Retrochoanitic septal necks represent the primitive condition in the Ammonoidea. In this study, we examine the morphology of the septal siphuncular complex of specimens of Agoniatites van...
Belemnites harleyi Mayer, 1866, originally described from the Jurassic of Normandy, has encountered diverging interpretations during the last 150 years of scientific research. It has subs...
Methane seeps in the Upper Cretaceous Pierre Shale of the U.S. Western interior contain a rich fauna including ammonites (Baculites, Hoploscaphites, Didymoceras, Placenticeras, Solenoceras), bivalves (Lucina), g...
The evolutionary process through which the siphonal zone of the cuttlebone of Sepia replaced the tubular siphuncle seen in other shelled cephalopods is poorly understood. Recently, porous connecting stripes, inte...
Ammonites and belemnites are among the most celebrated invertebrate fossils, and both groups played a crucial role in the early history of palaeontology. This article gives an overview of the sometimes twisted...
The latest Cenomanian to basal middle Turonian (Late Cretaceous) section at Vallecillo, Mexico, contains a continuous and highly fossiliferous sedimentary record. It preserves a detailed insight into a pelagic...
One of the most common modes of preservation of ammonites in the Upper Cretaceous US Western Interior is in concretions. We examine an accumulation of ammonites from a single concretion in the lower Maastricht...
The findings of fossilized ammonite soft tissues are extremely rare, so each specimen may be important for understanding the anatomy of these cephalopods. This paper deals with soft tissue fragments and imprin...
The nomenclature of Polyptychoceras, a Late Cretaceous heteromorph ammonite genus, and 18 related taxa is examined with a view to clarifying their nomenclatural availability, authors, dates of publication, and na...
The occurrence of statoliths within the Jurassic succession of south-west England and other parts of Europe is reviewed. Five ‘morphospecies’ have been identified, ranging in age from Hettangian to Kimmeridgia...
Spirula spirula is a unique deep-sea squid with unknown taxonomic status. Precise description of shell morphology may help to decide whether the genus contains one or more species. Here, ...
In the latest of a series of comments on Donovan’s research papers on the geology of Jamaica, Mitchell disagrees with van den Ende and Donovan’s lithostratigraphic assignment of the Thornton echinoid site, and...
The Neogene sedimentary fill of the Cocinetas Basin in northern Colombia preserves a rich record of marine invertebrates and can be analyzed in the context of a high-resolution stratigraphy and excellent chron...
Over the past four years, we have conducted extensive fieldwork in the Cocinetas Basin of La Guajira Peninsula, including geological mapping, stratigraphic descriptions, and exhaustive paleontological collecti...
Analyses of distances between succeeding septa throughout ontogeny of modern coleoids Sepiella japonica and Spirula spirula reveal that the first several septa (until ca. 6th–8th septa in Sepiella japonica and un...
New material of known roveacrinids from two Cretaceous sites in Texas is described. Upper Albian strata at Saginaw Quarry furnished rich material of Poecilocrinus latealatus and Roveacrinus pyramidalis; for these...
van den Ende and Donovan (2015: “Urchins on the edge: an echinoid fauna with a mixed environmental signal from the Eocene of Jamaica” Swiss J. Palaeontol. doi:
The fish fauna from the volcano-detritic sediments of Höwenegg has been known for more than half a century, when Tobien reported that cyprinid fishes are present at the site. Four years later, Jörg identified...
An echinoid fauna from the Early–Middle Eocene of Jamaica has yielded six species of echinoid: the phymosomatoid Acanthechinus peloria (Arnold and Clark); the oligopygoid Oligopygus sp.; the clypeasteroids Fibula...
The Cocinetas Basin of Colombia provides a valuable window into the geological and paleontological history of northern South America during the Neogene. Two major findings provide new insights into the Neogen...
The diversity of the order Cingulata is much higher in the fossil record than that represented by the extant species. While pampatheres, one of its extinct groups, are superficially similar to armadillos, rec...
Fossil material from 90 fossil localities, mostly paleokarstic, has been gathered together to study western European bat evolution and diversity from the middle Eocene (~44 Ma) to the early late Oligocene (~29...
Analyzing and interpreting life history data (e.g., aging and longevity, age at sexual maturity) are fundamental in many paleontological studies. In the case of extant and fossil fishes, otoliths, and to a les...
The material for the present paper is based on 50 kg of processed sediment from the Early Kimmeridgian of Geisingen. The most frequent crinoids comprise cups and brachials of the roveacrinid Saccocoma quenstedti ...
The Early Miocene Pirabas Formation represents extensive carbonate and siliciclastic belts deposited in marine coastal environments along the eastern Amazon coast. This formation was studied in its palynologic...
During the Cenozoic paucituberculatans were much more diverse taxonomically and ecomorphologically than the three extant genera of shrew-like marsupials. Among paucituberculatans, palaeothentids were abundant ...
Coral reef terraces are investigated in five localities around Marsa Alam on the Egyptian Red Sea Coast. The reefal limestones and the alternating terrigenous clastics are assigned to the Pleistocene Samadai F...
Several rhinoceros remains, collected in the Pliocene deposits of Northern Italy and usually ascribed to Dicerorhinus or Rhinoceros megarhinus, are revised; furthermore, unpublished Pliocene remai...
The early history of the comatulids is discussed based on recently described Jurassic specimens. Their centrodorsals suggest that the Order Comatulida is a monophyletic, synapomorphic clade that originated with P...
The extent of propodal tuberculation is considered taxonomically important for species of the callianassid genus Glypturus (Decapoda: Axiidea). Based on cheliped material from the Middle-Late Miocene of Iran, Gly...
Early and Late Jurassic mudstones of Europe are rich in remains of the isocrinid Balanocrinus. Recently collected material from the Early Pliensbachian of Sedan (France), from the Oxfordian of Andelot-Morval and ...
Intensive sampling of the lower portion of the Thaynes and Moenkopi Groups (Lower Triassic) at separate localities within the Confusion Range, Pahvant Range, Mineral Mountains, Star Range, Kanarraville, Cedar ...
Late Jurassic mudstones of France and Switzerland are rich in remains of the isocrinid Balanocrinus. From the early Late Oxfordian of Savigna (Département du Jura, France) Balanocrinus brachiospina is described a...
Lower Permian vertebrates from both terrestrial and aquatic organisms have been collected from Archer County, Texas, for over a century. These include preserved shark cartilage and spiral bromalites presumed t...
The small rotaliids (Foraminiferida) found in Cenomanian rock thin sections of Oman and Morocco are diversified. A continuum of morphotypes is divided within 3 taxa described as subspecies of Rotorbinella mesogee...
