Upper Cretaceous planktic foraminiferal biostratigraphy
Studia Universitatis Babes-Bolyai, Geologia, 2017 A high-resolution biostratigraphical zonation based on planktic foraminifera is developed for the Upper Cretaceous. It consists of twenty-five biozones defined with the aid of serial and coiled planktic foraminiferal taxa and presents the highest resolution developed with planktic foraminifera for this Series.

The Anatomical Record, EarlyView.Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Remarks on the type locality and current status of the foraminiferal species Rzehakina epigona (Rzehak, 1895) [PDF]
, 2001 A likely topotype locality is proposed for Rzehakina epigona. As the type specimen of Silicina epigona Rzehak, 1895 is assumed to be lost, we undertook a search for new material in the type area, Zdounky village in Moravia. A single locality provided a

The Anatomical Record, EarlyView.Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...
