The small, but rather deep pit in the internal mould of the body chamber of Upper Devonian Cyclopoceras (nom. nov.) abundans (Taxyceratidae, Discosorida) from Central Russia is described in this paper. Similar pi...
Phylogenetic relationships within the parvclass Disparida are evaluated using parsimony-based phylogenetic methods. The Disparida is a combination of forms with simplified morphologies and forms with highly sp...
In the northern Swiss Plateau and Jura Mountains, non marine Paleogene and Neogene deposits of the Swiss Molasse Basin or linked to the Upper Rhine Graben are examined in detail. The Late Eocene (Middle–Late P...
Substrate is a poor ichnotaxobase, yet it has been widely used for distinguishing the clavate (club-shaped) borings commonly produced by bivalves. A chert nodule from the Upper Cretaceous of Morocco encloses t...
Ichnotaxobases that provide internally consistent classification schemes for trace fossils such as burrows and borings include general form, branching, orientation, ornamentation, internal structure and fill, ...
Unusually well-preserved fenestrate bryozoans have been identified in Mississippian (Lower Carboniferous) building stones in Utrecht, the Netherlands. Specimens in adjacent properties presumably came from the ...
Studies of global palaeoecology through time usually ignore regional details. Such regional studies on palaeoecology are required to better understand both regional- and global-scale palaeoecolgical changes. W...
Mimosphinctes is an ammonoid genus that occurs in many localities that formerly surrounded the Prototethys. In spite of the great exposures and abundance of fossils, unequivocal and well-...
Platychelys oberndorferi is a stem pleurodire from the Late Jurassic of Europe. The majority of informative specimens originate from the Late Jurassic (late Kimmeridgian) Turtle Limestone...
Precise biostratigraphic dating of the Tojeira Formation (Late Jurassic, Early Kimmeridgian) of the Montejunto section of west-central Portugal, which has yielded important planktonic foraminiferal assemblages...
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...
Two Jurassic planktonic genera are emended and two new species and one subspecies of Jurassic planktonic foraminifera are defined. The genera are Globuligerina Bignot and Guyader 1971 and Conoglobigerina Morozova
A attachment structure, attributable to the sphaeronitid diploporitan Finitiporus boardmani Frest and Strimple, is documented herein from a hardground surface within the well-known middle Silurian (Wenlock) Massi...
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...
