Peace without money,war without Americans: challenges for European strategy

Just as the shift of the American strategic focus to Asia and the Pacific forces strategic autonomy upon Europeans, the financial crisis limits their means. In the age of austerity, dispersed efforts and spending on secondary issues have become unaffordable. Prioritizing and making strategic choices have become more important than ever. As no single European state can face all these challenges alone, a joint European strategy must assess where collective foreign and security policies can bring the most added value to the national effort. Through the European Union, Europeans have attempted as much in the 2003 European Security Strategy, but for lack of prioritization, the EU has so far underperformed. Yet the EU does have access to substantial means and possesses all the necessary instruments to pursue a comprehensive strategy. The key to their effective use is a collective European strategic review, starting from the vital interests that all European states have in common. Two priorities stand out: making a new start in Europe's relations with its southern neighbours after the Arab Awakening, and deciding which responsibilities Europeans will assume as security providers outside their borders after the American ‘pivot’ to Asia.     

Reassessment of the Styxosaurus snowii (Williston, 1890) holotype specimen and its implications for elasmosaurid plesiosaurian interrelationships

The holotype (KUVP 1301) of Styxosaurus snowii—one of the earliest described elasmosaurid plesiosaurians—consists of a well-preserved cranium, mandible and articulated sequence of anterior–mid-series cervical vertebrae found in the lowermost Campanian strata of the Smoky Hill Chalk Member in the Niobrara Formation of Kansas, USA. This particular specimen has proven important for recent phylogenies of Elasmosauridae, and is integral to resulting definitions of the subfamily-level clade, Styxosaurinae. Despite this, KUVP 1301 has not been redescribed or figured in detail since its original taxonomic establishment. We, therefore, re-evaluated KUVP 1301 and assessed its phylogenetic implications. Several notable character states are pertinent for diagnosing S. snowii at genus and species level: (1) an anisodont functional dentition comprising enlarged premaxillary and dentary teeth with a pair of maxillary ‘fangs’, and elongate posterior-most dentary teeth that overlap the upper tooth row; (2) a prominent dorsomedian crest extending from the tip of the premaxillary rostrum, and expanding into a low ‘mound-like’ boss between the external bony nasal openings and orbits; (3) a pronounced convex projection on the posterolateral edge of the squamosals; and (4) platycoelous post-axial cervical vertebral centra that are substantially longer than high, and bear both lateral longitudinal ridges and ventral notches. Character state comparisons with the congeneric subfamily specifier Styxosaurus browni suggest that taxonomic distinction is possible, but equivocal. We, therefore, restrict our definition of Styxosaurus to morphologies observable in KUVP 1301. Furthermore, phylogenetic analysis of our first-hand data returns inconsistent elasmosaurid intra-clade relationships, especially with regard to Styxosaurinae. Consequently, we posit that a more targeted reassessment of Elasmosauridae is necessary to resolve both species-level topologies and higher taxonomy within the group.
