Unknown fossil collections from the Bakony Mts, collected by J. Nosky Jnr. during his mapping activity in 1940s and 1950s were found storage facility of Hungarian Geological Institute 2010s. In these materials Upper Bajocian (Middle Jurassic) Som-hegy Bakonybél (formerly known as part Pénzeskút) some specimens determined 1959 ‘Canaliphylloceras’ nov. gen. sp.’ However, never published faunal st...

Approximately 40% of a skeleton including cranial and postcranial remains representing a new genus and species of basal neotheropod dinosaur is described. It was collected from fallen blocks from a sea cliff that exposes Late Triassic and Early Jurassic marine and quasi marine strata on the south Wales coast near the city of Cardiff. Matrix comparisons indicate that the specimen is from the lit...

As a tool for exploration of concealed coal seams by modern techniques, determination of the depth of erosion of coal seams with reference to the surface of angular unconformity underlying the remnants of a key bed is conducted for the first time in coal mines of Kerman region. The angular unconformity surface (the initial surface exposure of coal seams) separates the coal seams of Jurassic age...

The North Kitakami Belt in Northeast Japan mainly comprises accretionary complexes formed during the Jurassic to earliest Cretaceous. complex of is less studied compared age-equivalent Southwest Japan. Here, we provide additional data on formerly classified as Otori Unit, distributed northeastern part upper reaches Akka River Iwate Prefecture. Based detailed field mapping, clarified that Unit c...

the study area is situated in the middle part of the tabas block. it contains outcrops of rocks that formed along longitudinal faults in early cimmerian orogenic phase. the basin subsided along these faults from the late triassic to early cretaceous, which include two sedimentary cycles. a sedimentary cycle, related to upper triassic to bajocian is known as shemshak group. another sedimentary c...

The evolutionary radiation of dinosaurs in the Late Triassic and Early Jurassic was a pivotal event in the Earth's history but is poorly understood, as previous studies have focused on vague driving mechanisms and have not untangled different macroevolutionary components (origination, diversity, abundance and disparity). We calculate the morphological disparity (morphospace occupation) of dinos...

Fossils assigned to the predominantly deep-sea asteroid family Benthopectinidae Verrill, 1894 are described and their affinities reappraised. Detailed comparative morphology of ambulacrals, adambulacrals marginal ossicles has revealed that only some extinct taxa fall within morphological range modern representatives family. These include Jurapecten hessi Gale, 2011, J. infrajurensis sp. nov. (b...

We conducted chemical and isotopic analyses to develop and test a hydrogeological model of thermomineral water circulation in a limestone aquifer system at Caldas da Rainha (Central Portugal), contributing to future borehole-drilling and development strategies, with the aim of extracting waters with the best possible flow and/or temperature. The thermomineral waters (T approximately 33 degrees ...
