Inproceedings Reference An exceptionally well preserved primate petrosal from the Early Eocene of India
The Early Eocene (~54.5 Ma) Cambay Shale Formation at Vastan lignite mine (Gujarat, India) has yielded remains of both adapoid and omomyoid primates. The collection of primates includes not only jaws and teeth, but numerous exquisitely preserved postcranial elements. We report on the first cranial specimen for a primate from these deposits: an isolated left petrosal that preserves a partial stapes in anatomical position. The petrosal is identified as a primate based on the remnants of a petrosal bulla, and the presence of an ossified tube for the stapedial artery. The specimen documents a posterolateral entry of the internal carotid artery to the middle ear and a lateral course for the promontorial artery across the promontorium, characters most consistent with an attribution to Adapoidea. Of the adapoids published from the Vastan mine, body mass estimates based on the radii of the semicircular canals, calculated from high resolution microCT data, are most in line with previously calculated estimates for Marcgodinotius indicus, so the specimen is provisionally attributed to that species. Preserved anatomy is largely consistent with that described for Cantius. In particular, although the stapedial artery passed through a bony tube, the promontorial artery ran in an open groove from its origin off the internal carotid artery. This contrasts with the condition in omomyoids and most other adapoids, in which the promontorial artery was carried in a bony tube. The identification of an open groove for this artery in Cantius has been somewhat controversial, based on the state of preservation of published specimens. The petrosal from Vastan is extremely well preserved, demonstrating a clear opening in the internal carotid artery bony tube for the exit of the promontorial artery, and a well-demarcated groove on the promontorium for the latter artery that was clearly not enclosed. The absence of a bony tube for the promontorial artery in the oldest known adapoids suggests that the tube arose independently, in parallel, in Omomyoidea and Adapoidea. The promontorial artery is always enclosed in modern haplorhines, but when this artery is retained in living strepsirrhines it is often not fully enclosed by bone. Therefore, the primitive adapoid condition is more similar to that observed in Strepsirrhini. The antiquity and fine quality of preservation of this specimen make it relevant to reconstructing auditory morphology near the base of the primate tree.

Article Reference An expanded lower Eocene shelf sequence from the eastern Aquitaine Basin, SW France: stratigraphy and δ18O / δ13C excursions
The early Eocene is characterized by a succession of orbitally-controlled global stable carbon isotope excursions, with some being linked to climatic and related biotic perturbations. The impact of these isotopic excursions has been primarily studied in deep-sea sections under comparably stable conditions. In order to investigate the impact of global post-PETM isotopic signals on shallow marine settings, the Ypresian neritic ʻBlue Marls’ of the Corbières (SW France) were investigated. High-resolution records of microfossil biota and stable carbon and oxygen isotopes pinpoint biostratigraphic, paleoecologic and geochemic constraints. Calcareous nannofossil biostratigraphy positions the sequence in the upper part of zone NP11, possibly ranging into basal NP12, which is conformable with larger benthic foraminifera data indicating shallow benthic zone SBZ8. This implies a time span of about 0.4 Myr and high overall sedimentation rates of about ~ 32 cm/kyr for the section. A shallowing upward trend from outer neritic to coastal settings is observed in the development of the lithostratigraphy and the microfossil assemblage. The assemblages can be subdivided in seven larger biofacies and four ostracod assemblage zones. The lower third of the section is characterized by strongly fluctuating and partly high plankton/benthos-ratios for neritic settings. A final pronounced peak in plankton occurrence is associated with strong decrease of benthic biota, suggesting anoxic conditions in the outer neritic environment. Several local negative δ13C- and δ18O-excursions can be identified in the section. The upper, most pronounced and consistent negative δ13C excursion is tentatively linked to global carbon isotope excursion K (ETM3) based on the biostratigraphic constraints.

Article Reference An ichthyological borderland: The fishfauna of Nyungwe National Park and surroundings (Rwanda, East Africa)
Nyungwe National Park (NP) is a mountainous region situated in the southwestern part of Rwanda on Congo-Nile watershed. In spite of the high biodiversity in pri- mates, birds and plants, no fish were reported to occur in the park, probably because of the cold temperatures of the rivers. An expedition in 2022 examined the fish diver- sity within the Nyungwe NP and its buffer zones. Additional sampling was performed in the main river draining the park into Lake Kivu: the Kamiranzovu. Three hundred and twenty specimens belonging to 13 species were collected. Specimens were col- lected only in the western part of the park, draining towards the Congo basin. The diversity within the park proper was limited to two putative species within the com- plex of Amphilius cf. kivuensis, which were caught on either side of the Kivu–Rusizi watershed. In contrast, a higher fish diversity, including one clariid species and two species of Enteromius, was observed in the rivers at a lower altitude of the buffer zone. However, the highest species diversity was found near the mouth of Kamiran- zovu River, including 11 species, of which 4 were non-native: the guppy Poecilia reti- culata, Astatotilapia burtoni, the blue-spotted tilapia Oreochromis leucosticus and the Egyptian mouth-brooder Pseudocrenilabrus multicolor.

Article Reference An identification key for dermal denticles of Rajidae from the North Sea
As a result of more systematic fine sieving on archaeological sites, dermal denticles and isolated teeth of rays are now more frequently recovered than before. A detailed description of the teeth is available in the literature, but no comparative study of the morphology of the dermal denticles exists that allows the identification of such elements issued from archaeological sites. A key and illustrations are provided for the identification of the dermal denticles of 10 ray species from the North Sea. In addition, the ray denticles have been analysed from seven medieval and postmedieval sites showing their potential for the interpretation of ichthyo-archaeological assemblages.

Article Reference An integrated study of dark earth from the alluvial valley of the Senne river (Brussels, Belgium).
The present article discusses the integration of urban geoarchaeological and archaeobotanical data of a series of Dark Earth deposits situated in the alluvial valley of the Senne River in Brussels, Belgium. Due to their homogeneous character, their interpretation is a huge challenge for archaeologists. Through a caseby-case approach, a detailed picture of the sequence of different activities and (semi-) natural events, leading to the build up of Dark Earth at each individual site has been obtained. Among the activities, agricultural practices and waste management, which are rarely archaeologically recorded in urban contexts, have been identified. Despite being situated in a valley context, none of the sites presented an excellent preservation of the organic plant remains. However, through the integration of geoarchaeological and botanical data, the taphonomical history of the botanical remains could better be understood, allowing us to document the evolution of the environment surrounding the sites. Additionally, it has been demonstrated that the botanical study of Dark Earth units can also provide valuable information on vegetal consumption, in particular fruits. On a broader scale, this integrated geoarchaeologial and archaeobotanical study sheds some light on the process of urbanisation of the Senne alluvial valley between the 11the12th and the 16th century AD.

Article Reference An interdisciplinary study around the reliquary of the late cardinal Jacques de Vitry
The reliquary of Jacques de Vitry, a prominent clergyman and theologian in the early 13th century, has experienced several transfers over the last centuries, which seriously question the attribution of the remains to the late Cardinal. Uncertainty about the year of his birth poses an additional question regarding his age at death in 1240. The reliquary, located in the Saint Marie d’Oigines church, Belgium, was reopened in 2015 for an interdisciplinary study around his relics as well as the Treasure of Oignies, a remarkable cultural heritage notably built from Jacques de Vitry’s donation. Anthropological, isotopic and genetic analyses were performed independently on the remains found in the reliquary. Results of the analyses provided evidence that the likelihood that these remains are those of Jacques de Vitry is very high: the remains belong to the same human male individual and the historical tradition about his age is confirmed. In addition, a separate relic (left tibia) was analysed and found to match with the remains of the reliquary (right tibia). The unique Jacques de Vitry’s mitre, made of parchment, was sampled non-destructively and the extracted parchment collagen was analysed by a proteomic method in order to determine the animal species. The results showed that, surprisingly, not all parts of the mitre were made from the same species. All together, these findings are expected to fertilize knowledge carried by historical tradition around the relics of Jacques de Vitry and his related cultural heritage.
