Large canids at the Gravettian Předmostí site, the Czech Republic: The mandible
- Efforts to identify Paleolithic dogs or incipient dogs have been based mainly on examination of complete or nearly complete crania. Complete skulls are, however, very rare in the archaeological record. Because canid mandible are far more frequently found in Pleistocene assemblages, the objective of this study is to investigate whether it is possible to differentiate these jaws by metric and osteomorphological methods in two morphotypes: Paleolithic dogs and Pleistocene wolves. This paper is mainly based on the very rich canid assemblage from the Gravettian Předmostí site in the Czech Republic, but also includes a few mandible from several other European Paleolithic sites. This study provides additional evidence of the existence at Předmostí of the two canid morphotypes. The metric data indicate that the mandible of the Paleolithic dogs are shorter than those from Pleistocene wolves in all tested measurements of length, and the carnassial crown length is shorter in Paleolithic dogs compared with the length of this tooth in Pleistocene wolves. Furthermore, in eight of nine indexes, the Paleolithic dogs differ significantly from the Pleistocene wolves. The mandible of Paleolithic dogs differ also in non-metric features from the Pleistocene wolves: they present a high frequency of crowded premolars and backwards-oriented apex of the coronoid. This paper furthermore confirms that Paleolithic dogs occur at two late Upper Paleolithic sites (Eliseevichi, Verholenskaya) where previous studies had indicated their presence. In addition, we document the presence of Paleolithic dogs at another Gravettian site, Kostenki-8.

Biostratigraphic significance of brachiopods near the Devonian–Carboniferous boundary
- The biostratigraphic significance of selected uppermost Famennian (Upper Devonian) and lower Tournaisian (Mississippian) brachiopod genera, belonging to the orders Rhynchonellida (e.g. Araratella), Spiriferida (e.g. Sphenospira, Prospira), Spiriferinida (Syringothyris) and Productida (except Chonetidina), is discussed. Owing to the difficulties of identifying productidine and strophalosiidine genera, in contrast to rhynchonellides and spiriferides, the biostratigraphic potential of the former has generally been overlooked. Brachiopods flourished in neritic environments that were unfavourable for conodonts and ammonoids. In the absence of the latter traditional marker fossils, they are potentially important for locating the Devonian–Carboniferous boundary in shallow water depositional settings in conjunction with rugose corals and foraminifers. On a worldwide scale, further work is required to reach a better assessment of the aftermath of the Hangenberg biological Crisis on brachiopods, notably in revising the faunas from the classical areas of the Famennian and Tournaisian stages in Western Europe.
