Glomospirella cantabrica n. sp., and other benthic foraminifera from Lower Cretaceous Urgonian-type carbonates of Cantabria, Spain : biostratigraphic implications [PDF]
A new benthic foraminifer is described as Glomospirella cantabrica n. sp. from several sections of the Upper Aptian Reocín Formation and one occurrence in the lowermost Albian Las Peñosas Formation of Cantabria (northern Spain).

Late Jurassic and Early Cretaceous carbonate sediments of different age and facies, form the post-emplacement settings on top of the Mirdita Ophiolite Zone in northern Albania. They seal the early Late Jurassic emplacement of the ophiolite knappes, are the only datable relics overlying the ophiolites in the Late Jurassic - Early Cretaceous, aiding the ...

Towards a standard ammonite zonation for the Aptian (Lower Cretaceous) of northern Mexico
Detailed data on twenty-seven species of ammonites identified in three stratigraphic sections of northern Mexico, allow further refinement of the Aptian ammonite biozonations of previous authors. Four formal ammonite biozones are proposed.

The first definitive Middle Jurassic atoposaurid (Crocodylomorpha, Neosuchia), and a discussion on the genus Theriosuchus [PDF]
Atoposaurids were a clade of semiaquatic crocodyliforms known from the Late Jurassic to the latest Cretaceous. Tentative remains from Europe, Morocco, and Madagascar may extend their range into the Middle Jurassic.

Trace fossils from the middle Aptian sedimentary succession of the Bellezma Mountains, NE Algeria
The Aptian sedimentary succession exposed in the southern Bellezma Mountains contains a low diversity trace fossil assemblage, with ichnofossils being common in the middle part of the studied section. The recorded trace fossils comprise eight ichnogenera: Archaeonassa, Cochlichnus, Chondrites, Gyrochorte, Palaeophycus, Protovirgularia, Rhizocorallium ...
