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...

A new species of cassiduloid echinoids, Pygaulus baghinensis is reported for the first time from Aptian sediments of Baghin area, west of Kerman, Iran. The diagnostic features of the species are centrally positioned of the apical disc and approximately low profile of the test. Variation in gonopore size in different individuals allows to conclude that P. baghinensis is sexually dimorphic. Speci...

The facies distribution in time and space of sedimentary successions is controlled by a complex interplay between physical, chemical biological processes, which are nowadays difficult to construe from the geological record. Numerical models constitute valuable tool identify quantify such controlling factors permitting reliable 3D extrapolation prediction stratigraphic architectures beyond outcr...

PREMISE Fossils can reveal long-vanished characters that inform inferences about the timing and patterns of diversification living fungi. Through analyzing well-preserved fossil scutella, shield-like covers fungal sporocarps, we describe a new taxon early Dothideomycetes with combination unknown among extant taxa. METHODS Macerated clays from Potomac Group, lower Zone 1, Lower Cretaceous (Aptia...

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...

The crab genus Rathhunopon is exclusively known from Cretaceous rocks, mainly from Europe. Here two new European localities are presented: one in the Albian/Cenomanian of northern Spain yielding well-preserved specimens of Rathhunopon ohesum, and one from the lower Aptian at the German-Austrian border yielding Rathhunopon schrattenkalkensis n. sp. Both are found in association with coral reefs....
