Inproceedings Reference  The diet of a household in late and post-medieval Brussels: multidisciplinary analysis of cesspits from café Greenwich, Brussels
During renovation works in the cellar of a famous art nouveau building in the centre of Brussels -Café Greenwich- three late and post-medieval cesspits were discovered and excavated by the archaeological team of the Brussels-Capital region. Two cesspits, one dated to the 14th/15th century and the other to the beginning of the 16th century, still contained several layers of excellently preserved organic fll deposits. These were entirely sampled for archaeozoological, palynological, macrobotanical and paleoparasitological analyses. Some individual coprolites were collected for analyses as well. The integrated study gives information on human diet and health, and waste management. Indirectly, it also sheds light on social and economic status. In medieval times cesspits were not only used as dump for human faeces but often to discard various domestic waste as well. However, the flls of the analysed Brussels structures seem to consist almost exclusively of cess. The sieving residue subsists largely of small fruit pips. Ceramics and other archaeological objects were rare. Densities of archaeozoological remains vary considerably from one layer to the other. The faunal record consists generally of very small bones, mainly fsh but also small songbirds and chicken and a large quantity of tiny unidentifable bone fragments affected by the digestive process. The macrobotanical study reveals a large variety of plant foods: more than 40 species of economic plants were observed. Analysis of pollen signifcantly enlarges this spectrum with diverse species from which only leaves and/or flowers have been eaten. Furthermore the palynological study suggests the consumption of honey. The plant spectrum comprises several exotic and more expensive products while the faunal assemblage points to more common households.

File x-conference/x-cooltalk On using a Sensor Observation Service as an INSPIRE-compliant download service
Due to the use of sensors, the volume of scientific data produced every day has become massive,, so there is a strong need to organize them and to set up a data infrastructure for their efficient management. Open access, FAIRness (Findable, Accessible, Interoperable and Re-usable) and INSPIRE-compliance are increasingly becoming the norm for (environmental) data management. In order to achieve complex aspirations such as FAIRness and INSPIRE-compliance a simple idea might help: “Collect Once, Use many times”. Data collected today must be stored, documented and published in order to increase their knowledge extraction and to allow for an efficient re-use in the future. With the multiplication of sensor deployments in monitoring programmes, the new challenge is to publish time-series efficiently using state-of-the-art technologies. The MOMO project (MOnitoring and Modeling of the cohesive sediment transport and the evaluation of the effects on the marine ecosystem resulting from dredging and dumping operations) has been deploying tripod platforms consisting of ADCP and ADC sensor packages in the Belgian Part of the North Sea for the last two decades. These deployments generated considerable amounts of valuable data that are currently stored as csv-formatted text files that are not interoperable, both in terms of content and access protocol. The full potential of those data is currently safeguarded only thanks to the knowledge and expertise of the scientists involved in the project. The consequences of knowledge loss is therefore significant. The objective of this work is to explore the merit of implementing an Open Geospatial Consortium Sensor Observation Service (OGC SOS) for the publication of FAIR INSPIRE-compliant time-series data. The INSPIRE directive must be applied to data by the end of 2020 so the question is: “can a data provider be INSPIRE-compliant using SOS without complex and heavy developments?” The 52°North SOS implementation was chosen in this project, partly because they provide a complete open-source solution (database creation, SOS client and SOS viewer).

Inproceedings Reference Dormaal lizards in Belgium – a rare window into the earliest Eocene ‘greenhouse world’
During the Eocene, world climate experienced rapid and intense global warming, reaching a peak during the Palaeocene–Eocene Thermal Maximum (PETM), 56 my ago. The warmest global climate of the past 66 my occurred during the early Eocene epoch (about 56 to 48 mya) when megathermal floral elements, including palms, reached Antarctica. The increase in temperatures led to a rise in sea level, turning Europe into an archipelago. Data regarding the early Eocene herpetofaunas are scant, but the locality of Dormaal in Belgium represents one of the rare exceptions. The lizards consist of gekkotans, acrodontan and pleurodontan iguanians, anguimorphs such as glyptosaurines and the varanid Saniwa. These groups are believed to be thermophilic, and their appearance in this high latitude locality indicates that the tropics were expanded during this time. Some of these records also represent first appearances of these clades in Europe. Among them, a new iguanian taxon is represented by a unique tooth morphology – the teeth are bifurcated – indicating a specialization on trophic resources. However, because terrestrial ecosystems changed substantially during the Palaeogene, this might have caused higher extinction risk relative to generalists (e.g., the iguanian Geiseltaliellus). Understanding this geological epoch is relevant for present global climate change, including sea level rise, as well as the expansion of distribution of thermophilic taxa, including parasites that cause serious infectious diseases such as malaria.

Inproceedings Reference Les lézard Iguania (Pleurodonta et Acrodonta) de l’Eocène inférieur (MP7) de Dormaal, Belgique
Depuis quelques années, les lézards de l’Eocène basal de Dormaal (niveau-repère MP7), Belgique sont en cours de révision. Après le varanidé Saniwa orsmaelensis et les geckos, ce sont les lézards Iguania qui viennent de faire l’objet d’une étude approfondie. Ce groupe est représenté d’une part par les Acrodonta (incluant les agames et les caméléons), actuellement plutôt distribués dans l’Ancien Monde, et d’autre part par les Pleurodonta (les iguanes), principalement distribués dans le Nouveau Monde. Mais dans nos régions, ces deux groupes de lézards cohabitaient de l’Eocène basal, durant le Maximum Thermique Paléocène-Eocène (PETM), climat le plus chaud des 66 derniers millions d’années, jusqu’à la fin de l’Eocène inférieur (MP10, Prémontré, France). Aujourd’hui cette co-occurrence ne se retrouve plus qu’à Madagascar. Un maxillaire complet de l’agame Tinosaurus europeocaenus, le plus vieil agame européen, donne de nombreux caractères diagnostiques de cette espèce et permet de le rapprocher du genre actuel Leiolepis. Les différences avec Tinosaurus indicus de l’Inde, T. doumuensis de Chine et Tinosaurus sp. d’Amérique du Nord sont aussi discutées. Pour les pleurodontes, à côté du lézard bien connu Geiseltaliellus, un nouveau genre, Bifurcodentodon, a pu être identifié sur base d’un maxillaire présentant une morphologie dentaire toute particulière. En effet, la traditionnelle cuspide centrale des dents est dédoublée indiquant probablement un régime alimentaire spécialisé. Cette spécialisation pourrait avoir causé la perte de ce taxon en raison de la compétition avec les espèces plus généralistes et plus adaptatives faces au changement climatique du Paléogène.

Inproceedings Reference Retour au Wyoming : Une nouvelle faune et une nouvelle espèce du mammifère insectivore Didelphodus durant le Maximum Thermique Paléocène Eocène (PETM) dans le Bassin du Clarks Fork
La faune mammalienne de l’Éocène basal, durant le Maximum Thermique Paléocène-Éocène (PETM), est raisonnablement bien échantillonnée en Amérique du Nord, mais les mammifères de petite taille sont encore mal connus (Gingerich, 1989). Nous décrivons ici une nouvelle espèce de l’insectivore cimolestidé Didelphodus Cope 1882, découverte par la technique de lavage-tamisage qui a été appliquée pour extraire les fossiles d’un nouveau niveau concentré en restes de petits vertébrés. Ce niveau, daté du Wasatchien Wa-0 se trouve dans la zone du site SC-139 de Little Sand Coulee, appartenant à la Formation de Willwood et situé dans le Bassin du Clarks Fork, adjacent au Bassin du Bighorn. Après dissolution de concrétions carbonatées en laboratoire, différents fragments ont pu être restaurés, permettant de reconstruire un rostre crânien, les deux dentaires et la dentition supérieure et inférieure presque complète. Cette nouvelle espèce est la plus ancienne du genre Didelphodus connue en Amérique du Nord. Elle diffère des Didelphodus de l’Éocène inférieur par une taille nettement plus petite, des prémolaires relativement simples et une troisième molaire plus réduite par rapport aux molaires plus antérieures. Les précurseurs de Didelphodus ne sont pas connus avec certitude, et cette nouvelle espèce pourrait être un immigrant. Elle est provisoirement interprétée comme une forme naine comme d’autres mammifères du Wa-0 en raison de sa petite taille par rapport à l’espèce mieux connue D. absarokae Cope 1881 qui lui succède à partir du Wa-1. Financements Cette étude a bénéficié d’un financement de l’Institut royal des Sciences naturelles de Belgique. Références Gingerich, P.D., 1989.
