Absence of a pneumatic foramen on posterior side of Pterosauria proximal humerus suggests attribution of Cretornis hlavaci to Neoazhdarchia. It has a unique construction Azhdarchoidea Cretornis of the distal ulna with a dorsal articulation surface placed distinctly proximal to the tuberculum shared Cretaceous only with the non-azhdarchid azhdarchoid Montanazhdarcho minor from the Campanian of North Czech Republic America. Cretornis hlavaci differs from the latter taxon by the structure of its humerus and distinctly longer wing metacarpal. It is more derived than “Tapejaridae” but shares with Azhdarchidae the del- topectoral crest of the humerus displaced distally from humeral head. Cretornis cannot be assigned to Azhdarchidae because of the oval cross section of the second wing phalanx. A unique rhombic outline of the distal humerus of Cretornis hlavaci is a possible autapomorphy for this taxon. Its wing span estimated as 1.5e1.6 m. This is the first taxon of non-azhdarchid pterosaurs known from the Upper Cretaceous of the Eastern Hemisphere. © 2015 Elsevier Ltd. All rights reserved. 1.

Fric identified the most complete Lhota near Chocen( ¼Chotzen in German papers) in the Kingdom of bone (humerus) as a coracoid and mentioned also the humerus Bohemia, part of the Austro-Hungarian Empire (now Czech Re- fragment and almost all forearm bones which are “astoundingly public). This discovery was studied by Antonín Fric (Anton Fritsch short proportionally to the coracoid” (Fric, 1881a:275). Later Fric in some German papers), a prominent Czech paleontologist (Ekrt, republished the figure in a book devoted to his studies of the fossils 2008). First he identified the bones as bird remains and, in a from the Bohemian Cretaceous (Fric, 1883: fig.45), but did not provide any additional description.

In azhdarchoids the ulnar crest is Ornithocheirus where all Cretaceous toothed pterosaurs were directed caudally (ventrally in flight position), similar to that in placed at that time. Lydekker changed the species epithet from ornithocheirids and pteranodontids. Bennett (1989: fig.2(6, 7)) hlavaci to hlavatschi following the German transliteration of this introduced this character based on comparison with the humerus Slavic name.

The Dalsenalm section within the Grabenbach Formation of the Lattengebirge was investigated in detail. The lithofacies is character- ized by shelf marls and minor tempestite sandstones.

Palaeontology in the virtual era BOOK OF ABSTRACTS 6 4 PRESENTATION The 1st Palaeontological Virtual Congress (1st PVC) is just the natural consequence of the evolution of our surrounding world, with the emergence of new technologies that allow a wide range of communication possibilities. Within this context, the 1st PVC represents the frst attempt in palaeontology to take advantage of these new possibilites being the frst international palaeontology congress developed in a virtual environment. This online congress is pioneer in palaeontology, offering an exclusively virtual-developed environment to researchers all around the globe. The simplicity of this new format, giving international projection to the palaeontological research carried out by groups with limited economic resources (expensive registration fees, travel, accomodation and maintenance expenses), is one of our main achievements. This new format combines the benefts of traditional meetings (i.e., providing a forum for discussion, including guest lectures, feld trips or the production of an abstract book) with the advantages of the online platforms, which allow to reach a high number of researchers along the world, promoting the participation of palaeontologists from developing countries.

  • First Evidence of Azhdarchid Pterosaurs from the Late Cretaceous of Hungary
    First evidence of azhdarchid pterosaurs from the Late Cretaceous of Hungary ATTILA ŐSI, DAVID B. WEISHAMPEL, and CORALIA M. JIANU Ősi, A., Weishampel, D.B., and Jianu, C.M. 2005. First evidence of azhdarchid pterosaurs from the Late Cretaceous of Hungary. Acta Palaeontologica Polonica 50 (4): 777–787. New remains of an azhdarchid pterosaur were discovered from the Upper Cretaceous (Santonian) Csehbánya Formation at the Iharkút vertebrate locality in the Bakony Mountains, western Hungary. Among the isolated bones, consisting prin− cipally of 21 symphyseal jaw fragments, four cervical vertebrae, a right radius, and some fragmentary limb bones, is a complete articulated mandible that represents one of the best−preserved mandibular material of any presently known azhdarchid pterosaur. The complete edentulous jaw, referred to Bakonydraco galaczi gen. et sp. nov. posesses several fea− tures diagnostic for azhdarchids which prove that Bakonydraco belongs to this group. The cervical vertebrae exhibit azhdarchid features and consequently are referred to as Azhdarchidae indet. The discovery of these fossils helps to under− stand the construction of the azhdarchid mandible and provides new insight for studying the feeding style of the edentulous azhdarchid pterosaurs.

The compositional development of the sporomorph assemblages in the Gosau basin is applied for stratigraphical correlation of the basal coal series and transgressional units in adjacent occurrences of the Gosau Group.

  • Partial Skull and Endocranial Cast of the Ankylosaurian Dinosaur Hungarosaurus from the Late Cretaceous of Hungary: Implications for Locomotion
    Palaeontologia Electronica palaeo-electronica.org Partial skull and endocranial cast of the ankylosaurian dinosaur Hungarosaurus from the Late Cretaceous of Hungary: implications for locomotion Attila Ősi, Xabier Pereda Suberbiola, and Tamás Földes ABSTRACT A partial skull of ankylosaur from the Upper Cretaceous (Santonian) Csehbánya Formation in Iharkút and the endocranial cast taken from it are described. The mor- phology of the exoccipital, the elongated ‘neck’ region of the basioccipital, the shape of the occipital condyle, and the different flexure of the medulla relative to the forebrain unambiguously differentiate this specimen from the basicranium of Struthiosaurus, so it is assigned to Hungarosaurus sp. Whereas the endocranial cast reflects a brain gener- ally similar to those of other ankylosaurs, the dorsally hypertrophied cerebellum (also present is Struthiosaurus transylvanicus) is quite unusual within the group suggesting a more sophisticated cerebral coordination of posture and movement, and perhaps a more cursorial locomotary habit than predicted for other ankylosaurs.

Abstract: The Upper Cretaceous Piesting Formation (Gosau Group, Grünbach Syncline) comprises a neritic to deep-water succession a few hundred meters thick. The recently established Piesting Formation replaces the old and confusing stratigraphical terms lnoceramenschichten and lnocera­ menmergel (lnoceramus beds, lnoceramus marls), and Orbitoidensandstein. Three lithofacies can be distinguished: a lower part of grey marls with tempestites, a middle part of sandstones and conglomerates, and an upper part that consists of sandy marls with a few turbidites. The terrestrial to shallow-marine Grünbach Formation (formerly "Coalbearing Series") underlying the Piesting Formation is Early Campanian in age. The Piesting Formation ranges in age from Campanian to Early Maastrichtian. A late Campanian age is indicated by Pseudokossmaticeras brandti (REDTEN­ BACHER, 1873) and foraminifera (ÜBERHAUSER in: PLOCHINGER, 1961). Early Maastrichtian is indicated by Pachydiscus neubergicus und inoceramid bivalves of the Muntigl fauna near Salzburg (TRöGER et al., 2000, TROGER et al., in press) and by Pachydiscus epiplectus (RrnTENBACHER, 1873) from the Piesting Formation of the nearby village of Muthmannsdorf. lnoceramids and trace fossils dominate in the section of the sports field of Piesting. Late Campanian nannozones CC18-CC22 are indicated from the section of the "Umfahrungsstraße" S Piesting, in palaeomagnetic terms probably chron 32 N.
