The new taxon Paraclausastrea vorarlbergensis sp. nov. is described from the upper Barremian-lower Aptian (Schrattenkalk Fm.) of western Austria (Vorarlberg). It belongs to the montlivaltiids and is characterized by thamnasterioid to submeandroid corallite integration, diameters of corallites ranging between 3 and 6.5 mm, and septa that are generally developed in 4 incomplete cycles in 6 genera...

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...

Abstract Despite the previous interpretations of evolutionary scenarios Qatar Arch, present study aimed to a new complementary scenario lay out probable effects another basement fault, corresponding physical shape Arch. A remote sensing was carried based on geological and geophysical data interpretations, obtained from some national international databases, including GIS-based global geology Ha...

In Western Kopet Dagh, the lower Cretaceous carbonate series contains distinctive assemblages of calcareous algae, chiefly Dasycladales which are primarily studied in this work. Based on the significant presence of certain species, the Zard Formation, assigned to the Valanginian and, in its upper part, to the Hauterivian or base of the Barremian, is subdivided into two intervals, respectively A...

New material of an iguanodontid styracosternan ornithopod from the Lower Cretaceous Iberian Peninsula is described. The cranial and postcranial skeletal remains are Barranco del Hocino-1 site. These fossils (Iguanodontidae sensu Xu et al., 2018) represent first medium-sized Upper Sequence Blesa Formation (Barremian). new characterized by a unique combination characters that suggest they corresp...

We report a new pleurodiran turtle from the Barremian Morro do Chaves Formation, Sergipe-Alagoas Basin, Brazil. We tested the phylogenetic position of Atolchelys lepida gen. et sp. nov. by including it in a comprehensive cladistic analysis of pleurodires. The new species is a basal member of Bothremydidae and simultaneously the oldest unambiguous crown Pleurodira. The biogeographic and chronost...

The non-marine trigonioidid bivalves show five phases of radiation in the Cretaceous of Pal-Asia: pre-Aptian (?Valanginian/Hauterivian-Barremian), Aptian, Albian, Cenomanian and Turonian-Maastrichtian. Their distribution patterns show two distinct palaeo-river systems feeding trigonioidids. Before the Cenomanian, the river system occupied the southwestern-southern-southeastern Pal-Asian contine...
