Abstract Since the 1980s, Upper Jurassic lithographic limestone of Causse Méjean (southern France) has been known by local naturalists to yield fossils. However, until beginning 21st century, this plattenkalk remained largely undersampled and scientifically underestimated. Here, we present results two decades prospection sampling in Drigas Nivoliers quarries. We provide first palaeontological i...

Variations in the carbon isotopic composition of carbonate and organic (?13Ccarb ?13Corg) are generally used to record perturbations global cycle, which turn closely linked changes climate. However, because climate gradients on Earth, assignment “global” signal ancient records is not straightforward. Here, we report ?13C values material Upper Jurassic Lower Cretaceous sedimentary Vaca Muerta Fo...

Abstract Squat lobsters within Galatheoidea are very diverse with over 1,300 extant species that live in all marine ecosystems, but their fossil record, starting the Middle Jurassic, consists of only ~200 species. Consequently, much remains to be learned about biodiversity, phylogeny, and paleobiogeography. We describe five new ( Galatheites sforum n. sp., Kimmeridgian, Late Germany; Vasconilia...

s Volume for the Krakow Congress (in Volumina Jurassica no. 4, 2006). The Working Group members were then asked in a two-point ballot: (1) That the Flodigarry section, Staffin Bay, Isle of Skye, Scotland be proposed as the GSSP section; (2) Either that the Pictonia flodigarriense Horizon or the Pictonia densicostata Horizon should be the primary marker for recognition and correlation of the bas...

A number of hydrocarbon discoveries have been made recently in the Flemish Pass Basin and Central Ridge, offshore Newfoundland, Canada, but there is only limited geological information available. The primary goal this study was to determine sedimentary provenance paleodrainage patterns mudstones sandstones from Upper Jurassic Rankin Formation, including Lower Kimmeridgian Source Rock (organic-r...

Adult large-bodied theropods are often found with numerous pathologies. A large, almost complete, probably adult Allosaurus specimen from the Howe Stephens Quarry, Morrison Formation (Late Kimmeridgian-Early Tithonian), Wyoming, exhibits multiple pathologies. Pathologic bones include the left dentary, two cervical vertebrae, one cervical and several dorsal ribs, the left scapula, the left humer...

The Vaca Muerta Formation (Tithonian–early Valanginian) is the main source rock in Neuquén Basin and most important unconventional shale resource South America. In present study, organic geochemistry, electron microscopy basin petroleum system modelling (BPSM) were combined to evaluate properties related processes along a transect from early oil (east) dry gas (west) window. unit characterized ...

Theropod dinosaurs form a highly diversified clade, and their teeth are some of the most common components of the Mesozoic dinosaur fossil record. This is the case in the Lourinhã Formation (Late Jurassic, Kimmeridgian-Tithonian) of Portugal, where theropod teeth are particularly abundant and diverse. Four isolated theropod teeth are here described and identified based on morphometric and anato...
