The stratigraphy, palaeoecology and palaeobiogeography are outlined for two genera and ten species of Jurassic planktonic foraminifera described in Gradstein et al. (Swiss J Palaeontol 2017. doi:
Planktonic foraminifera originated in late Early Jurassic and, for reasons poorly understood, only underwent proliferation of species and geographic spreading from mid-Cretaceous onwards. Their evolutionary de...
Over 70 publications on Jurassic planktonic foraminifera, particularly by East and West European and Canadian micropalaeontologists, are summarized and briefly annotated. It provides an annotated historic over...
Many palaeontologists and sources of palaeontological data refer to ‘drill holes’ or ‘small round holes’ in shells, produced by invertebrate borers and sources of palaeoecological data. But such terminology ma...
The taxonomy is modernized and updated for Jurassic planktonic foraminifera using all available literature and stratigraphic series of sediment samples from Canada, Portugal, France, Switzerland, Poland, Lithu...
The studies presented in this special issue describe and evaluate otoliths in situ in 18 species of extinct Paratethyan fishes, 17 from Sarmatian, and one from Karaganian deposits. Together with previously des...
In the final section of our series of studies on Sarmatian fishes from the Paratethys with otoliths in situ, we deal with three pleuronectiform species. Each species is re-defined based on the type material pl...

Percomorph fishes are relatively uncommon in the Sarmatian deposits of Dolje and Belgrade where they are primarily of small size, often representing juvenile specimens. Here, we describe otoliths in situ from “Sc...
Articulated fossil fish skeletons with otoliths in situ provide a unique opportunity to link these two, otherwise independent data sets of skeletons and otoliths. They provide calibration points for otoliths a...
Two relatively small tridactyl tracks from the Middle Jurassic Xintiangou Formation of northeastern Sichuan are assigned to cf. Anomoepus based on low length/width and anterior triangle ratios, and a relatively s...
Moldavichthys switshenskae is established as a new fossil genus and species of the family Clupeidae, subfamily Alosinae, to encompass the specimens from the Sarmatian of Moldova, which hi...
Comatulid feather stars are rare fossils in the Early Jurassic, providing only patchy insights into the early evolution of the group. Here, we describe new finds of comatulids from the late Pliensbachian to la...
Autochthonous Triassic sediments of the Vieux Emosson Formation near Lac d’Emosson, southwestern Switzerland, have yielded assemblages with abundant archosaur footprints that are assigned to chirotheriids base...
For a land with a dearth of natural rock outcrops, the Netherlands abounds with urban ‘exposures’ of fossiliferous rocks such as building stones, street furniture and street art. In the Rapenburg in Leiden, se...
Karaganops is established as a new fossil genus of the family Clupeidae, subfamily Clupeinae, to encompass the nominal species Sardinella perrata Daniltshenko 1970 from the Karaganian of ...
Rich material of a tiny pelagic roveacrinid from the lower member of the Carnian Xiaowa Formation, Guanling area (Guizhou Province, Southwest China), is described. The remains are assigned to a distinct species,
Whereas our knowledge of small arboreal Paleogene birds has greatly increased in the past years, that of the larger birds coexisting with them is far less detailed. Particularly poorly known and, hence, widely...
Gadid otoliths are among the most common otoliths in the Neogene of Europe. To date, these have been recorded in situ and therefore correlated with the skeletal record only in two cases, Paratrisopterus avus and
Evolutionary prospection is the study of morphological evolution and speciation in calcareous plankton from selected time-slices and key sites in the world oceans. In this context, the Ne...
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...
Several well-preserved otoliths were extracted from four slabs containing fish specimens of Atherina suchovi. Atherina suchovi is one of the five Atherina species recorded from the Middle Miocene of the Central a...
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...
Here we are providing a review of aptychi records in ammonites of Boreal origin or that inhabited Boreal/Subboreal basins during the Bathonian–Albian with special focus on new records and the relationship betw...
Thirty species of nautiloids and ammonoids were identified based on the material collected from peninsular Thailand. Ordovician nautiloids: a sactorthoceratid nautiloid (Sactorthoceras banestanensis) from Changwa...
This study reviews the Callovian to Volgian biozonation in West Siberia and discusses the problems related to zonations of Jurassic sequences relying only on well core data. The West Siberian Callovian to Volg...
The top of the Querales Formation is well exposed at the Quebrada Corralito section, 17 m thick, in northern Venezuela. The section, dominated by siliciclastic accumulations of fine-grained sediments, preserve...
In order to test the hypothesis that complex suture lines in ammonoids reinforced their shell strength, intraspecific variation of sutural complexity and shell morphologies (whorl shape and septal thickness) o...
The mode of life of the turricones and colchicones are considered against the background of functional–morphological analyses of their shell modifications during ontogeny. Among turricones, there were more or ...
In September 2014, the 9th International Symposium Cephalopods—Present and Past (ISCPP) and the 5th International Coleoid Symposium were held at the University of Zurich. The numerous contributions from two jo...
Nine proposals of aptychus (sensu stricto) function have been published (in historical order): operculum, micromorphic males, lower mandible, protection of gonades, ballast for lowering of aperture, flushing of b...
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...
The structure of pristine preserved shells of Jurassic and Cretaceous ammonoids was examined to identify whether the character states of varices and constrictions are homologous or homoplasic traits. The inter...
A new, marine osteichthyan (bony fish) fauna from the Early Triassic of northern India is presented. The material was collected in situ at localities within Pin Valley (Lahaul and Spiti District, Himachal Prad...
The Late Paleocene locality of Louvois is located about 20 km south of Reims, in the department of Marne (France). These marly sediments have yielded numerous vertebrate remains. The Louvois fauna is coeval wi...
Rare Palaeozoic chert clasts collected from gravels in the bedload of the River Maas in the province of Limburg, south-east Netherlands, are rich in crinoid debris. These were transported during the Late Plioc...

In the Carboniferous Shannon Basin, Western Ireland, the majority of ammonoids spanning the Serpukhovian-Bashkirian Stages (E1–R2 biozonal indices) are preserved as flattened, partial 2D impressions, for which id...
The ram’s horn squid Spirula spirula is a unique deep-water marine organism whose life cycle remains enigmatic. Interpretations of its ecology and habitat preferences are currently based solely on dredging, on fi...
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 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...
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...
