Geological model of the Ypresian Clay.
- This study is framed in a programme, set up under coordination by Lie Sun Fan (Faninbel bvba), to create depth models for the important clay layers in the subsurface of Belgium, focussed on the clay layers of the Boom (Rupelian) and Kortrijk (Ypresian) Formations. The results concerning the Boom Clay were reported separately (Walstra & Dusar 2013). A characterisation of borehole breakouts in Ypresian clays with reference to geophysical well logs has also been reported (De Ceukelaire et al. 2012). The present document only treats the Ypresian Clay complex. It is tried to define and model the totality of the Ypresian aquiclude, including the Kortrijk Formation and overlying clay units of the Tielt Formation, irrespective of the lithostratigraphical subdivisions in use. The model is based on high-quality borehole data and geophysical well logs from the archives of the Geological Survey of Belgium (GSB) and Databank Ondergrond Vlaanderen (DOV)1, complemented by Dutch data (DINOloket and NLOG of TNO-GDN)2. Interpretations of boreholes were critically re-evaluated and modified when necessary. Models of interpretation are discussed in the next chapter. Compared to previous mapping projects by GSB (i.e. Tertiary Isohypse Maps by Vancampenhout 2004 and Quasi-3D Model of the Lower-Rupelian and Tongrian by Vancampenhout et al. 2008), additional new data were used and existing interpretations were fine-tuned with the currently accepted lithostratigraphical subdivisions in Belgium. Because different (bio-) lithostratigraphical subdivisions exist, these are first discussed in view of their relevance for the objectives of this study, i.e. to define the Ypresian Clay complex as a single comprehensive aquiclude. This proved to be a difficult and time-consuming exercise, not only due to the palaeogeographical variability of the subunits, but also due to the variety of stratigraphic terminology in use, the different interpretation criteria applied and the inconsistent links between them. From a technical perspective, the methodology used to realise the depth model is largely similar to the one of the Quasi-3D model of the Lower Rupelian, except that the fault blocks in the east of the study area were not treated separately. Furthermore, so-called “depth maps” were produced – indicating the depth of the top and base of the clay unit below a variable ground level instead of relative to sea-level. In the first part of this report, an overview of the position of the modelled units within the Belgian lithostratigraphical schemes is provided and discussed.3 The following chapters present the data used and the cartographic methodology applied. The results are presented as a number of maps and finally some problem areas are indicated where the model would benefit from further fine-tuning. Note that the term “Ypresian Clay” (“Ieperklei”) is an informal designation – throughout this report this term covers both the Kortrijk Formation and the overlying clayey units of the Tielt Formation (assigned to the Kortemark and Egemkapel Members, as will be demonstrated). This term is more restrictive than the stratigraphic denomination Ypres (Ieper) Group which encompasses also the overlying more sandy units included in the Tielt and Gentbrugge Formations. Because of its relevance for defining the upper limit of the Ypresian Clay, this study is the first attempt to systematically recognize and map the Egemkapel Member. 1 https://dov.vlaanderen.be/dovweb/html/index.html 2 http://www.dinoloket.nl; http://www.nlog.nl/nl/home/NLOGPortal.html 3 We discuss usage of lithostratigraphic terms.

Were bears or lions involved in salmon accumulation in the Middle Palaeolithic of the Caucasus? An isotopic investigation in Kudaro 3 cave
- Bone fragments of large anadromous salmon in the Middle Palaeolithic archaeological layers of Kudaro 3 cave (Caucasus) suggested fish consumption by archaic Hominins, such as Neandertals. However, large carnivores such as Asiatic cave bears (Ursus kudarensis) and cave lions (Panthera spelaea) were also found in the cave and could have been responsible for such an accumulation. The diet of these carnivores was evaluated using carbon, nitrogen and sulphur isotopes in faunal bone collagen. The results suggest that anadromous fish were neither part of the diet of either cave bear (vegetarian) or cave lion (predators of herbivores from arid areas) and therefore provide indirect support to the idea that Middle Palaeolithic Hominins, probably Neandertals, were able to consume fish when it was available.

New proviverrines (Hyaenodontida) from the early Eocene of Europe; phylogeny and ecological evolution of the Proviverrinae
- We describe six proviverrine species from the Early Eocene of France. Three species are new: Minimovellentodon russelli sp. nov. from Mutigny [mammal palaeogene (MP)8 + 9], Boritia duffaudi sp. nov. from La Borie (MP8 + 9), and Leonhardtina godinoti sp. nov. from Grauves (MP10). We describe new specimens and propose new generic combinations for three species from MP10: Protoproviverra palaeonictides, Matthodon menui, and Oxyaenoides lindgreni. We also propose a new generic combination for the primitive Eoproviverra eisenmanni (MP7). Matthodon menui was previously considered as a possible oxyaenodontan, but the new fossils clearly support its reference to Hyaenodontida. Leonhardtina godinoti and Ma. menui are the oldest occurrences for these genera, which were previously unknown before the Middle Eocene. Moreover, the discovery of the proviverrine Mi. russelli in Mutigny implies that the Proviverrinae dispersed in Northern Europe between biozone Palaeocene-Eocene (PE) III (Abbey Wood) and biozone PE IV (Mutigny). This also supports a homogenization of the European faunas during the Early Eocene. The dispersal is concomitant with the disappearance of the oxyaenodontans, arfiines, and sinopines (Hyaenodontida) from Europe. The proviverrines may have filled the ecological niches left vacant by the disappearance of the other carnivorous mammals. With 20 genera and over 30 species, proviverrines were successful in Europe. We performed the first phylogenetic analysis comprising almost all the Proviverrinae. Our analyses indicate that the Proviverrinae diversified greatly during the Early Eocene Climatic Optimum and show a general trend towards specialization throughout the Eocene.
