Here, we describe part of a large-bodied macrophagous plesiosaur jaw from the lower Bajocian (Middle Jurassic) Passwang Formation near Arisdorf in the Basel-Land canton of Switzerland. The specimen preserves t...
The most important section of most research papers, which will be read by the widest audience, is the abstract. But abstracts are often written in a hurry after the paper is finished, when the author is in a r...
A hardground surface in the middle Silurian (Wenlock: Sheinwoodian) Massie Formation is well exposed at the New Point stone quarry in Napoleon, southeastern Indiana, USA, where it is densely encrusted by pelma...
Armored catfishes are grouped within the clade Loricariidae. They are typically Brazilian freshwater fishes that show a high taxonomic diversity in South America and are distributed from Costa Rica to Buenos A...
Crinoids are uncommon fossils in the Cenozoic. This scarcity means that even disarticulated elements are of note. Two species of the isocrinine Isselicrinus Rovereto are described from their disarticulated column...
Freshwater gobies played an important role in the Miocene paleolakes of central and southeastern Europe. Much data have been gathered from isolated otoliths, but articulated skeletons are relatively rare. Here...
The family Lechritrochoceratidae Flower, 1950 includes the earliest cephalopods acquiring a lateral pair of retractor muscles—a diagnostic character of the Nautilida. The embryonic shell of Silurian lechritroc...
During a fieldtrip of the 10th International Cephalopod Symposium to the Tafilalt (SE Morocco), a fauna with the so far oldest ammonoid of the region was discovered at the top of the basal Emsian Deiroceras Limes...
In March and April 2018, the 10th International Symposium Cephalopods—Present and Past (ISCPP) was held in Fes, Morocco. Meeting and the post-conference fieldtrip were organized by representatives of the Westf...
New records of ammonites showing poorly known sutural anomaly, so-called sutural pseudoinversion, are discussed. For the first time, sutural pseudoinversion was found in non-heteromorph Jurassic and Lower Cret...
Serially sampled oxygen isotope ratios (δ18O) from fossil and modern cephalopods may provide new insight into the behavior and longevity of individuals. Interpretation of these data is generally more difficult th...
The fossil biota of the Eocene Yellow Limestone Group of Jamaica is diverse in vertebrates and, particularly, invertebrates. However, its invertebrate trace fossils remain understudied. Herein, we document the...
A juvenile orthocerid Dolorthoceras sp. from the Frasnian (Late Devonian) of the Polar Urals in NW Russia is the first recorded ectocochleate cephalopod showing fibrous structures and the first Devonian cephalopo...
High-level classification of the nautiloid cephalopods has been largely neglected since the publication of the Russian and American treatises in the early 1960s. Although there is broad general agreement among...
Homoplasy is a common phenomenon in the evolution of the Cephalopoda. Many homology problems accordingly light up phylogenetic debates. The initial segment of the siphuncle, the so-called ‘caecum’, is one of t...
One of the best-known faunal assemblages that characterizes the past ecosystems from South America comes from the Santa Cruz Formation in Argentina. This assemblage is formed by an endemic fauna, which include...
The species Chieseiceras dolomiticum n. sp. along with other ammonoid species (Latemarites latemarensis, Halilucites rusticus) helps constraining the age of the cyclic platform interior portion at Latemar (Dolomi...
The genus Basiloceras gen. nov. containing the two species B. goliath sp. nov. and B. david sp. nov. is described. It belongs to the Acleistoceratidae within the Oncocerida. Both species are from the Middle Devon...
The Antilles include over 100 islands, each with a rock record that embraces different slices of the stratigraphic succession; this is probably the most beguiling geological quality of the region. Both authors...
A wide variety of aquatic vertebrates from fluvio-lacustrine facies of northern South America (Colombia and Venezuela) have been used as unequivocal evidence to support hydrographic connections between western...
Two new records of Cenozoic sepiids from the Mediterranean area are described and discussed. While the single, fragmentary specimen from Pliocene (Zanclean) strata in northwestern Italy can only be identified ...
Two specimens of the Late Mississippian ammonoid cephalopod Metadimorphoceras sp. were recovered from the Bear Gulch Limestone in Montana. This unit was deposited in the lowest part of the Big Snowy Basin, where ...
A new genus of ophiuroid, Luxaster n. gen., is described based on articulated skeletal remains preserved as external molds. The new genus belongs to the Paleozoic stem-group family Protasteridae. It includes two ...
A Berriasian age planktonic foraminifera assemblage from a section near the village of Krasnoselivka in the Tonas River Basin, Crimea contains Favusella hoterivica (Subbotina), ?Favusella sp., Conoglobigerina gul...
Diploporitans had subspherical thecae, which usually were attached to hard substrates either directly with an attachment disc at the base of their theca or with a stem and holdfast. After the death of the anim...
Lizards were and still are an important component of the European herpetofauna. The modern European lizard fauna started to set up in the Miocene and a rich fossil record is known from Neogene and Quaternary s...
Accumulations of ammonoid shell fragments have been recovered from the Hangenberg Black Shale (latest Devonian) of the southern Maïder (eastern Anti-Atlas, Morocco). They are here interpreted as regurgitalites...
Predation has been hypothesized as important to crinoid ecology, and numerous crinoid traits have been linked to predation. However, testing such hypotheses requires some assessment of predation intensity, or ...
Well-preserved external moulds of articulated brittle stars from the middle to late Cenomanian (early–Late Cretaceous) “Lower formation” of the Mifune Group on the island of Kumamoto, southern Japan, are descr...
A small, albeit diverse, assemblage of dissociated ophiuroid ossicles, mostly lateral arm plates, from the upper Maastrichtian Peedee Formation temporarily (August 1998) exposed at North Myrtle Beach (Horry Co...
Actinometra blakei, originally described from a single specimen, was subsequently placed in synonymy, and has not been mentioned in print since 1931. This re-description was prompted by the collection of three ne...
Exceptionally well-preserved ossicles of xenomorphic stalked crinoids (Echinodermata) were found into the Late Ypresian clay of the Tuilerie de Gan (Pyrénées-Atlantiques, southwestern France). Three kinds of c...
Cyrtocrinids are morphologically diverse crinoids of the Mesozoic, yet their origin and early evolution are still poorly understood. Here, we attempt to disentangle the early evolutionary history of the cyrtoc...
One of the characteristic features used to define the echinoderms is five-fold symmetry. The monobathrid camerate crinoid genus Amphoracrinus Austin normally has five arms, but an aberrant specimen from Salthill ...
Crinoids are a common and well-studied faunal component of the Upper Ordovician (Katian; Edenian) Kope Formation in the greater Cincinnati Arch region, USA. However, a relatively fresh outcrop exposing the Sou...
The spines of echinoids are common palaeontological objects, but rarely supply more than this minimal information, because they are difficult to identify to genus or species. Some taxa, particularly cidaroids,...
Stalked crinoids have long been considered sessile. In the 1980s, however, observations both in the field and of laboratory experiments proved that some of them (isocrinids) can actively relocate by crawling w...
The schizasterid echinoid genus Hypselaster Clark, 1917, is recorded for the first time from the Midawara Formation (Middle Eocene, Lutetian), which crops out east Maghagha area, east Nile Valley, Eastern Desert,...
Asteroids of the Jurassic—Recent group of the Velatida evolved during the Late Triassic or Early Jurassic from the family Tremasteridae, previously placed, as a subfamily, in the Asterinidae. Tremasterids and ...
Large, denuded tests of holasteroid echinoids were robust benthic islands in the Late Cretaceous seas of northwest Europe. A test of Hemipneustes striatoradiatus (Leske) from the Nekum Member (Maastricht Formatio...
