Anatomy and variability of "Cuvierichelys parisiensis", a geoemydid turtle that crosses the Eocene-Oligocene boundary in Belgium

Abundant material of turtles from the early Oligocene site of Boutersem-TGV (Boutersem, Belgium), is presented here. No information on the turtles found there was so far available. All the turtle specimens presented here are attributable to a single freshwater taxon that is identified as a member of Geoemydidae, Cuvierichelys. It is the first representative of the ‘Palaeochelys s. l.–Mauremys’ group recognized in the Belgian Paleogene record. This material, which allows to know all the elements of both the carapace and the plastron of the taxon, cannot be attributed to the only species of the genus Cuvierichelys so far identified in the Oligocene, the Spanish form Cuvierichelys iberica. The taxon from Boutersem is recognized as Cuvierichelys parisiensis. Thus, both the paleobiogeographic and the biostratigraphic distributions of Cuvierichelys parisiensis are extended, its presence being confirmed for the first time outside the French Eocene record. The validity of some European forms is refuted, and several characters previously proposed as different between Cuvierichelys iberica and Cuvierichelys parisiensis are recognized as subjected to intraspecific variability.

The Challenge of Migration and the Global Security Strategy of the European Union

This article discusses the challenges of irregular migration for the security of the EU. They are analyzed starting with the European Security Strategy 2003, and the Report on its Implementation, 2008, and notes many failures: The EU Members did not follow the directives adopted in Brussels, the mismanagement of migration and asylum policies, and numerous actions that can be characterized or described as improvised, scattered or irresponsible. The 2016 Global Strategy recognizes these failures and call attention to the European leaders to reconsider how the EU functions and operates, suggesting the need for greater unity and cooperation to achieve a more effective migration policy. However, the article points out that practically all of the sections of the new Strategy dealing with migration were already embodied in previous Strategies, and stress that in parallel with the publication of the 2016 Global Strategy, actions are already undertaken, such as the EU readmission agreements signed with several important third countries of origin.
