Neogyroporella? gawlicki n.sp., a New Dasycladale from the Upper Jurassic–Lower Cretaceous “Lärchberg Formation” of the Northern Calcareous Alps, Austria
The Upper Jurassic to Lower Cretaceous shallow water platform carbonates of the Northern Calcareous Alps (Plassen Formation, “Lärchberg Formation”) and the resedimented deposits of the latter within basinal series (Barmstein Limestone, Tressenstein Limestone) are currently under re-investigation (SCHLAGINTWEIT et al., 2003; GAWLICK et al., 2005). This shallow water development is directly linke...
متن کاملSubduction tectonic erosion and Late Cretaceous subsidence along the northern Austroalpine margin (Eastern Alps, Austria)
The Late Cretaceous to Early Tertiary subsidence history of the Northern Calcareous Alps (NCA) records the effect of two independent basin formation mechanisms at the northern leading margin of the Austroalpine unit. The terrestrial to shallow-marine sediments of the Lower Gosau Subgroup were deposited mainly within small, fault-bound basins during a phase of strike-slip faulting from the late ...
متن کاملMiddle Jurassic Radiolarians from the Western Pacific
Middle Jurassic radiolarians have been recovered from the western Pacific for the first time. The oldest faunas are assigned to the middle and upper Tricolocapsa conexa Zone, indicating a Bathonian/Callovian age. The faunas contain more than 30 species and are characterized by an abundance of small nassellarians with a constricted distal end. The faunas compare well with Tethyan faunas, and are...
متن کاملGosavisiphon gen. nov. based on Halimeda paucimedullaris SCHLAGINTWEIT & EBLI, 1998: a remarkable macroalga (Udoteaceae?) from the Late Cretaceous of the Northern Calcareous Alps, (Austria and Germany), with affi nites to Late Palaeozoic and Late Triassic phylloids
The new genus Gosavisiphon with the type-species Halimeda paucimedullaris SCHLAGINTWEIT & EBLI, 1998, tentatively referred to the Udoteaceae, is described from the Late Cretaceous (Middle/Late Cenomanian-Santonian) of the Branderfl eck Formation and the Lower Gosau Subgroup of the Northern Calcareous Alps (Austria, Germany). It is a plurimillimetric to pluricentimetric marine, hard-substrate dw...
متن کاملA rare occurrence of Late Hettangian ammonites (Angulaticeras and Paracaloceras) in the Mediterranean Tethys (Rif, Northern Morocco)
This paper describes and illustrates three newly discovered Late Hettangian ammonite specimens from the “Dorsale calcaire” (Calcareous Range) of the internal units of the Rif (Northern Morocco). Two additional Early Sinemurian ammonite specimens are also studied and all the Early and middle Lower Jurassic ammonites collected earlier in this area and illustrated in the literature are included in...
