Palaeoepidemiology in extinct vertebrate populations: factors influencing skeletal health in Jurassic marine reptiles [PDF]
Palaeoepidemiological studies related to palaeoecology are rare, but have the potential to provide information regarding ecosystem-level characteristics by measuring individual health.

Composition and age span of sedimentary deposits of the Transantarctic Basin system vary between different regions of the Transantarctic Mountains. Moreover, whereas the regional stratigraphic successions have been very well established in some areas of East Antarctica, such as the Allan Hills or the Beardmore Glacier, they remain virtually unexplored ...

Early Jurassic (latest Toarcian) brachiopods from the northeastern margin of the Western Tethys (Central Iran) and their paleobiogeographical significance [PDF]
Brachiopod fauna from central Iran, recorded in the upper part of the Shemshak Group and attributed to the upper Toarcian (Pseudoradiosa-Aalensis zones), are reported for the first time in Iran.

Eocene belemnites from Hungary
Abstract The Middle Eocene nummulitic limestone at Dudar, Transdanubian Hungary, has yielded several belemnite rostra during the last 60–70 years. The correct interpretation of these fossils was made possible by the fact that one of these specimens retained the remnants of the conotheca within the alveolus, while others preserved the conical, tapering ...

Tmetoceratidae (Ammonitina) fauna from the Gerecse Mts (Hungary) [PDF]
Taxonomic and stratigraphic problems of the family Tmetoceratidae and the genera Dumortieria, Catulloceras, Cotteswoldia, Pleydellia and Tmetoceras included in it are briefly discussed. Fifteen species of Tmetoceratidae are described and illustrated from

The Nevis and Mamore ranges near Fort William comprise some of the most popular and spectacular of all Scotland's mountains including the highest peak, Ben Nevis. The beauty of this mountainous region is the product of a long and complex geological evolution, spanning 800 million years of Earth's history.

The Cardigan Bay Basin (UK) may have functioned as a deep and narrow strait, and thereby influenced Early Jurassic oceanic circulation through the northern and southern Laurasian Seaway, and between Boreal and Peri-Tethys domains.

Sr-Isotope Stratigraphy: Assigning Time in the Campanian, Pliensbachian, Toarcian, and Valanginian [PDF]
The trend of marine 87Sr/86Sr against stratigraphic level through sections, whether linear or not, can identify hiatuses and changing rates of sedimentation through those sections and so be a valuable constraint on attempts to assign numerical ages to ...

Abstract Iguanodontia (Dinosauria, Ornithischia) is a speciose group of herbivorous dinosaurs that include the famous genus Iguanodon, one of foundational members of the clade Dinosauria. Despite their very long history of research, several aspects of their systematic relationships and their evolutionary history remain somewhat nebulous.
