Remains of theropod dinosaurs are very rare in Northern Germany because the area was repeatedly submerged by a shallow epicontinental sea during the Mesozoic. Here, 80 Late Jurassic theropod teeth are described of which the majority were collected over decades from marine carbonates in nowadays abandoned and backfilled quarries of the 19th century. Eighteen different morphotypes (A-R) could be ...

The fossil record of cuttlefish, squid and octopus has received relatively little attention. Among malacologists, the opinion is widespread that these mainly softbodied coleoids have a poor fossil record. However, thanks to Konservat-Lagerst tten such as the Early Jurassic Posidonian Shales of Holzmaden (Germany), the Middle Jurassic La-Voulte-sur-Rh ne (France) and the Late Jurassic Limestones...

The Bulkley Suite of intrusions are spatially associated with numerous important mineral occurrences in westcentral British Columbia. Previous K-Ar dating studies indicated that the Bulkley Suite ranges in age from 70 to 84 Ma (Carter, 1981). The purpose of this study is to better constrain the timing of Bulkley Suite magmatism and associated mineralization in the northern Tahtsa Lake District....

New evidence is presented on the Triassic–Jurassic boundary in northern Lusitanian Basin, Portugal, based miospore assemblages from a composite Upper Triassic to Lower Jurassic succession of Silves Group. The latter comprises, base top, Conraria, Penela, Castelo Viegas and Pereiros formations. Three informal palynological zones have been documented compared with coeval palynozones West South Eu...

The Qaidam Basin is one of the major coal-bearing basins in northeastern China with coal seams mainly preserved Lower–Middle Jurassic. Middle Jurassic sedimentary environment, sequence stratigraphy, paleoclimate, and accumulation have been extensively studied, while characteristics depositional evolution Lower series are less well known. We systematically analysed facies association, system, ba...
