The stratigraphy of the upper Fredericksburg and lower Washita groups northern Texas southern Oklahoma is described, biostratigraphical correlation within region, further afield, using microcrinoids, ammonites, planktonic foraminiferans inoceramid bivalves summarised. taxonomy roveacrind microcrinoids revised by senior author, a new genus, Peckicrinus , with type species Poecilocrinus porcatus ...

The Albian- Cenomanian (Kazhdumi Formation) sediments from northeast of Shiraz, Zagros Basin, represents a carbonate sedimentary succession and contain diverse gastropods and bivalves. Detailed studies on 80 samples of invertebrate macrofauna on two stratigraphic sections led to recognized 2 species and 5 genera of gastropods and 7 species and 13 genera of bivalves assemblages. The abscence of ...

The Ortaköy-Barcın Plateau Cretaceous sequence is located in the Antalya nappes outcropping throughout Akseki-Güzelsu-Köprülü which northern of Gündoğmuş (Antalya). begins with Albian limestones containing mainly Pseudonummoloculina aurigerica, Praechrysalidina infracretacea, Nezzazata isabellae, Trochamminoides coronus, Glomospira urgoniana, Vercorsella arenata, Cuneolina parva and they are co...

Rare erratic clasts – extraneous rock types occur in the Upper Cretaceous Chalk, including a local basal facies, Cambridge Greensand. The underlying Albian Gault Clay and Hunstanton Red Chalk Formations have also yielded erratics. discovery of these erratics, their description development hypotheses to explain origins significance are reviewed. They became subject scientific interest with inter...

We investigate the present-day orogenic architecture of Pyrenean-Cantabrian junction corresponding to a boundary between inverted rift segments using seismic interpretation, field data, and borehole information. This was formerly attributed major NNE-SSW striking Pamplona transfer fault segmenting Basque-Cantabrian Mauléon basins during both rifting convergence. Our study shows that results fro...

Modern hydrothermal vent communities are based on chemosynthesis by microbial primary producers. Molecular phylogenetic divergence estimates indicate that many of the dominant taxa arose during Cenozoic and Cretaceous; however, fossil record from these time periods is poor. One occurrence such Cretaceous pertains to six volcanogenic massive sulphide deposits in Troodos ophiolite Cyprus. These r...
