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...
The article presents the results of U-Pb isotope dating (SHRIMP-II, VSEGEI, Saint Petersburg) zircon crystals extracted from plagiorhyolites Monakh Cliff in area Cape Fiolent western part Mountainous Crimea (southern suburb Sevastopol). a concordant age estimate 168.3±1.3 Ma was obtained 20 crystals. It exactly corresponds to Bajocian/Bathonian boundary Middle Jurassic according International C...
“Doming–rifting–spreading” constitute the main phases of classical plate tectonics. The Middle–Upper Jurassic succession East Greenland is interpreted as reflecting formation, deflation and onlap a rift dome, similar to contemporaneous domes in North Sea, Denmark southern Sweden. forms northwards backstepping onlapping early N–S oriented basin. Deposition ranged from coastal over shallow marine...
Sediments of Stefanets Mb. (Etropole Fm.), consisting mainly shale and siltstones, are investigated by Rock-Eval pyrolysis. The samples from the Middle Jurassic section (Bajocian in age), outcropping within western part Balkan orogenic system Bulgaria, were analyzed to study their hydrocarbon generative potential. obtained TOC contents range 0.69–1.97 wt.%. Inorganic carbon (TIC) total sulphur ...
Two new docodontans, Simpsonodon sibiricus sp. nov. and Hutegotherium yaomingi gen. et sp. nov., and a new specimen of Itatodon tatarinovi Lopatin et Averianov, 2005 are described from the Middle Jurassic (Bathonian) Itat Formation of Krasnoyarsk Territory in West Siberia, Russia. A new phylogenetic analysis, incorporating 37 dental and mandibular characters and 18 docodontan and outgroup taxa ...
Atoposaurids were a clade of semiaquatic crocodyliforms known from the Late Jurassic to the latest Cretaceous. Tentative remains from Europe, Morocco, and Madagascar may extend their range into the Middle Jurassic. Here we report the first unambiguous Middle Jurassic (late Bajocian-Bathonian) atoposaurid: an anterior dentary from the Isle of Skye, Scotland, UK. A comprehensive review of atoposa...
