The Aktulagay section, west Kazakhstan: a key site for northern mid-latitude Early Eocene stratigraphy.
- A section at Aktulagay (west Kazakhstan), in the Peri-Tethys realm, exposes mid-neritic to upper bathyal Ypresian marls, clays and silts. These range from Zone NP10 to early Zone NP14, with abundant and diverse microfossil assemblages. Multidisciplinary analysis has identified dinoflagellate cyst, calcareous nannofossil, planktonic and benthic foraminiferid and pteropod zones and events. Calibration of a key interval in the evolution of the shark Otodus has been possible for the first time. Episodic low-oxygen facies, including sapropelic clays widely distributed in Peri-Tethys, are represented here and can be placed within a detailed biostratigraphic framework. The current lithostratigraphic terminology is modified, with the introduction of the Aktulagay Formation. Paleoenvironmental aspects are discussed; five depositional sequences are tentatively identified. This section can be correlated in detail with the succession in the North Sea Basin, with implications for paleogeographic reconstructions. High-resolution biostratigraphic calibration between disparate fossil groups makes this a key reference section for northern mid-latitude Ypresian biostratigraphy.

New amphisbaenian lizards from the Early Paleogene of Europe and their implications for the early evolution of modern amphisbaenians
- Three new amphisbaenian lizard taxa are described from the Early Paleogene of Western Europe. Two new basal forms, Polyodontobaena belgica gen. et sp. nov. from the Early Paleocene of Hainin (Belgium) and Camptognathosaurus parisiensis gen. et sp. nov. from the Late Paleocene of Rivecourt-Patit Pâtis and Cernay-lès-Reims (France), are characterised by a dentary lacking a strong angle at the symphysis and bearing 10 to 12 massively built and conical teeth. These two taxa form the new family Polyodontobaenidae. A third new amphisbaenian, Blanosaurus primeocaenus gen. et sp. nov., is also described from the Early Eocene of Dormaal (Belgium), Condé-en-Brie and Prémontré (France) and represents the oldest modern amphisbaenian lizard of Europe, tentatively assigned to Blanidae. It is characterised by a reduction of tooth number and by the presence of a strong angle at the symphysis. Palaeobiogeographic considerations suggest a first hypothesis that the Eocene forms would have evolved from the Paleocene species.The second hypothesis would be that as for the lizard Scincoideus haininensis, primitive amphisbaenians were present in Europe from the Paleocene,whereasbeginning in the Early Eocene only modern forms with typical reduced dentition (fewer than 10 teeth) are present. The origin of these modern forms is very likely related with the dispersal of the first modern mammals.
