Abstract. Albian to Turonian carbonate deposits at three different locations of the Lower Saxony Cretaceous and thereby European mid-Cretaceous epeiric shelf sea were investigated for their fossil agglutinated foraminiferal fauna. In this study, 71 samples from two quarries drill cores treated with formic acid, which enabled study assemblages even in highly lithified limestones. total, 114 spec...
The deposits corresponding to the Upper Cretaceous Neuquén and San Jorge Gulf basins from northern central Patagonia have provided two of most complete sequences terrestrial vertebrate faunas all Gondwanan landmasses. Among carnivorous components, carcharodontosaurid theropods appeared as common elements during Early earliest Late in Patagonia. Although recorded mostly lower Turonian, isolated ...
Planktonic foraminiferal population dynamics and benthic radiolaria distributions combined with ?13C ?18O measurements of both bulk carbonate foraminifera provide clues concerning the paleoceanographic changes across Cenomanian-Turonian boundary interval Oceanic Anoxic Event 2 (OAE 2) at southern high latitudes. Samples analyzed are from Integrated Ocean Discovery Program (IODP) Expedition 369 ...
A second species of protorhyssaline wasps (Braconidae) is described and figured from inclusions in Upper Cretaceous (Turonian) amber of the Raritan Formation in New Jersey, USA. Rhetinorhyssalites emersoni, gen. n., sp. n., is distinguished from other protorhyssalines, particularly the contemporaneous Protorhyssalus goldmani.
We report the Narmada Seaway began in India during largest global sea-level transgression and Oceanic Anoxic Event 2 (OAE2) δ13C excursion late Cenomanian to early Turonian. The progressed eastward Turonian-Coniacian reached Jhilmili by end of Maastrichtian. During this time Godavari Seaways may have joined via Narmada-Tapti rift formed a Trans-India Seaway. history major seaway is entombed fos...
carbonate successions of the sarvak formation (late albian? to mid-turonian) together with the carbonate of the ilam formation formed the second important hydrocarbon reservoirs in sw iran and persian gulf. facies analyses were carried out on the upper parts of the sarvak formation in western part of the ahwaz oilfield (az-63 well) to interpret depositional environment. lithologically, the uppe...
