The Middle–Late Jurassic gonyaulacacean dinoflagellate cyst genus Gonyaulacysta is characterised by an epicyst which around twice the length of hypocyst. sulcus L-type and may be slightly sigmoidal in shape, but never S-type sensu stricto. forms with sulcuses have developed into species sulcuses. jurassica , holotype nomenclatural type genus, had a global distribution. A total 151 been assigned...

[1] Regional 2D multichannel seismic, borehole, dredge and outcrop data, together with burial models for strata in southwest Iberia, are used to investigate the tectono-stratigraphic signature of multiphased rifting on divergent margins. Our burial model reveals that Mesozoic extension occurred during three main phases, each comprising distinct subsidence pulses separated by short-lived periods...

Crinoids are largely considered as good indicators for determining environmental conditions. They robust proxies inferring changes in salinity and sedimentation rate substrate type. Some crinoid groups ( e.g ., certain comatulids, cyrtocrinids, millericrinids) have a depth preference, thus, making them useful palaeodepth estimation. The hypotheses that distribution is substrate-dependent (rock ...

The most prolific reservoir intervals in the Barents Sea are found Upper Triassic to Middle Jurassic Realgrunnen Subgroup, deposited during a major change structural evolution of basin which greatly influenced its development and distribution. effects evident one petroleum provinces SW Sea, Hoop Area. Due condensed nature succession, tectonostratigraphic has been enigmatic. We use range differe...

The breakup of Pangaea and the rapid opening Ligurian Central Atlantic oceans during Middle Jurassic resulted in widespread volcanism accompanied by significant shifts global environments, climates, floras. Although major is a plausible driver such changes, linking these phenomena hindered lack detailed sedimentary records from which to evaluate cause effect. Here, we link environmental, climat...

This study showcases the value of drone photogrammetry in creating a meter-scale geological model complex carbonate geobodies. Although is now commonly used for modeling sedimentary facies and architecture sandstone outcrops, its use not widespread geomodels Drone can generate accurate line-drawing correlation detailed analysis along inaccessible vertical faces outcrops permits observations unr...

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...
