Echinoid remains recovered from Štramberk-type limestones (Tithonian to Berriasian) in southeast Poland comprise mainly disarticulated corona plates and fragmentary spines. Nevertheless, twelve different taxa could be recognised among the material, most of which could be identified at family or genus level. In addition, eleven types of spines were documented, including at least one additional echinoid group. The fauna is dominated by various cidaroid groups, which account for the bulk of the material. Non-cidaroid echinoids are represented by rare finds belonging to diademataceans, hemicidarids, stomechinids, arbacioids, and phymosomatoids (spines only). Faunal composition is closely similar to that of Oxfordian and Kimmeridgian strata in France and Poland. None of the echinoid taxa identified exclusively occurs in Lower Cretaceous strata, although many of them range into that interval. Echinoid data thus hints at a Late Jurassic age of the assemblage. Test fragments of Tylocidaris sp. found among the material may represent the oldest record of the genus. © 2015 E. Schweizerbart'sche Verlagsbuchhandlung, Stuttgart, Germany.

Rhodoliths are a common producer of carbonates on modern and ancient shelves worldwide, and there is growing evidence that they thrive on volcanic insular shelves. However, little is still known on how rhodoliths cope with the demands of this particularly dynamic environment. In this study, the focus is placed on fossil rhodoliths from a Pliocene sequence at Santa Maria Island, Azores, in order to gain further insight into the life cycle (and death) of rhodoliths living within a mid-ocean active volcanic setting. These rhodoliths occur as a massive accumulation within a larger submarine volcano-sedimentary sequence that was studied from the macro- to the micro-scale in order to reconstruct the paleoenvironmental conditions under which the rhodolith accumulation was deposited and buried. All fossil rhodoliths from this setting are multi-specific and demonstrate robust growth forms with a lumpy morphology. Moreover, taphonomical analyses show the succession of several destructive events during rhodolith growth, suggesting life under a highly dynamic system prior to stabilization and burial. The rhodoliths therefore tell a story of an eventful life, with multiple transport and growth stages, owing to the environment in which they lived. Transport and deposition to their final resting place was storm-associated, as supported by the general sedimentary sequence. In particular, the sequence features an amalgamation of tempestites deposited under increasing water depths, sediment aggradation, and before burial by volcanic activity. This transgressive trend is also attested by the overall characteristics of the volcano-sedimentary succession, which exhibits the transition to subaerial environment in excess of 100 m above the rhodolith bed. © 2016, Springer-Verlag Berlin Heidelberg.

Half a century after the first scientfic meeting dedicated to marine spiny skinned animals (Deuterostomia: Echinodermata) was held in Washington, DC, we take this opportunity to provide information on a number of historical aspects related to the echinoderm scientfic community. Apart from shedding light on the historical origins of modern echi noderm conferences, the present contribution presents photographs taken during the first meeting of echinoderm researchers in 1963 as well as during the first installments of the International Echinoderm Conference and the European Conference on Echinoderms. Furthermore, we provide background information on publication series dedicated solely to the Echinodermata as well as descriptions of selected digital resources that focus on echinoderms. Finally, we present a number of echinoderm conference logos and flyers in addition to selected information about speciic echinoderm meetings. © A. Ziegler et al.

Among the rich late Middle Miocene vertebrate fauna from Gratkorn [MN(7+)8] in Styria, Austria, birds are among the rarest of vertebrate fossils. Only isolated elements - 13 bones and two claws - have been recorded, most of which are fragmentary, thereby hampering systematic determinations. However, four different taxa have been identified as representing at least three different species of galliforms (Miogallus altus, cf. Palaeocryptonyx edwardsi, cf. Palaeocryptonyx sp.) and the mousebird Necrornis cf. palustris. All of these taxa have been known to be present before from Middle Miocene deposits in Europe, but there existence has been proven for the first time in Austria. © 2014 Senckenberg Gesellschaft für Naturforschung and Springer-Verlag Berlin Heidelberg.

A disarticulated, though still roughly associated partial Deinotherium skeleton from the late Middle Miocene (late Sarmatian sensu stricto; 12.2-12.0 Ma) Gratkorn locality (Austria) is described. Based on dimensions and morphology of the material it can be determined as a medium-sized taxon of Deinotheriidae and definitively assigned to the genus Deinotherium. This specimen from Gratkorn confirms the osteological differences in the postcrania between Prodeinotherium and Deinotherium. As the diagnostically important p/3 is missing on the specimen it can only be assigned to Deinotherium levius vel giganteum. The Gratkorn specimen is one of not many skeletons of a medium-sized taxon of Deinotheriidae and one of only a few well-dated late Middle Miocene occurrences in Central Europe with associated dental and postcranial material. © 2014 Senckenberg Gesellschaft für Naturforschung and Springer-Verlag Berlin Heidelberg.
