Article Reference New hadrosaurid dinosaurs from the uppermost Cretaceous of north-eastern China
Several hundred disarticulated dinosaur bones have been recovered from a large quarry at Wulaga (Heilongjiang Province, China), in the Upper Cretaceous (Maastrichtian) Yuliangze Formation. The Wulaga quarry can be regarded as a monodominant bonebed: more than 80% of the bones belong to a new lambeosaurine hadrosaurid, Sahaliyania elunchunorum gen. et sp. nov. This taxon is characterised by long and slender paroccipital processes, a prominent lateral depression on the dorsal surface of the frontal, a quadratojugal notch that is displaced ventrally on the quadrate, and a prepubic blade that is asymmetrically expanded, with an important emphasis to the dorsal side. Phylogenetic analysis shows that Sahaliyania is a derived lambeosaurine that forms a monophyletic group with the corythosaur and parasauroloph clades. Nevertheless, the exact position of Sahaliyania within this clade cannot be resolved on the basis of the available material. Besides Sahaliyania, other isolated bones display a typical hadrosaurine morphology and are referred to Wulagasaurus dongi gen. et sp. nov., a new taxon characterised by the maxilla pierced by a single foramen below the jugal process, a very slender dentary not pierced by foramina, and by the deltopectoral crest (on the humerus) oriented cranially. Phylogenetic analysis indicates that Wulagasaurus is the most basal hadrosaurine known to date. Phylogeographic data suggests that the hadrosaurines, and thus all hadrosaurids, are of Asian origin, which implies a relatively long ghost lineage of approximately 13 million years for basal hadrosaurines in Asia.

Article Reference New Holothuria species from Australia (Echinodermata: Holothuriidae), with comments on the origin of deep and cool holothuriids.
Two aspidochirotid species, new to science, from the continental slope of southern Australia are described: Holothuria (Panningothuria) austrinabassa O’Loughlin sp. nov. and Holothuria (Halodeima) nigralutea O’Loughlin sp. nov. The first represents the southernmost documented holothuriid, and is the sister species of the northernmost holothuriid species Holothuria (Panningothuria) forskali Delle Chiaje. The second is a very recent offshoot of the wide-ranging Indo- west Pacific Holothuria (Halodeima) edulis Lesson. Morphological and molecular genetic differences between these species pairs are detailed. Holothuria (Halodeima) signata Ludwig is raised out of synonymy with H. edulis.A lectotype for Holothuria (Halodeima) signata Ludwig is designated, The status of the subgenera Panningothuria Rowe and Halodeima Pearson is discussed. The occurrence of multiple madreporites in Halodeima is discussed.

Article Reference New lissamphibians and squamates from the Maastrichtian (Late Cretaceous) of the Haţeg Basin (Romania)
Numerous remains of amphibians and squamates were discovered in the continental sediments of theMaastrichtian Sânpetru Formation, south of Pui Village (Haţeg Basin, western Romania). The lissamphibians are represented by a salamander−like allocaudatan (Albanerpeton sp.) and at least two discoglossid frogs (cf. Eodiscoglossus sp. and cf. Paradiscoglossus sp.). The numerous lizards are represented by, e.g., the teiid Bicuspidon hatzegiensis sp. nov., and for the first time in a Late Cretaceous site, by two species of the paramacellodid Becklesius (Becklesius nopcsai sp. nov. and Becklesius cf. B. hoffstetteri). Snakes are also present in this site by an indeterminante madtsoiid, which represents the first occurrence of this family in eastern Europe. The presence of Albanerpeton in this site confirms that this genus appeared in Europe by at least the Late Cretaceous instead of Miocene as previously thought. The presence of both Albanerpeton and Bicuspidon in Haţeg Basin suggests a North American influence on eastern European amphibian and lacertilian faunas by Maastrichtian times.

Article Reference New mtDNA and Isotopic Evidence on Late Pleistocene Cave Bears in the Balkans: the Case-study of Magura Cave, NW Bulgaria
Recent genetic studies have shed light on the phylogeography of cave bears; however, their paleoecology and their diet are still debated, and data from south-eastern Europe are still scarce. Magura Cave, in northwest Bulgaria, has delivered rich faunal assemblages from the Late Pleistocene. The chronology of the excavated area spans from ca. 35 kya to more than 50 kya; the oldest stratigraphic layers being associated with final Middle Palaeolithic tools. The fauna comprises herbivores and carnivores, and potentially different taxa of cave bears, the dental remains of which also showed different tooth morphotypes, suggesting the co-existence of different dietary adaptations. We investigated the mitochondrial DNA (mtDNA) lineages of the cave bears from Magura Cave as well as the stable carbon and nitrogen isotope composition of the faunal assemblage. Our data revealed that, regardless of the tooth morphotypes, only maternal lineages of Ursus ingressus were present in Magura Cave. Interestingly, one specimen with Ursus arctos mtDNA was also found, showing a clear carnivore diet. In contrast, the U. ingressus specimens had a predominantly herbivorous diet. The tooth morphotypes were associated with significantly different δ13C values, suggesting different dietary adaptations.
