Inproceedings Reference Paleocene and Eocene bird assemblage from the Southern North Sea Basin
Numerous bird bones from the Paleocene and early Eocene of the Belgian and Paris basins have been collected by amateur paleontologists. Four bones from the early-middle Selandian of Maret, Belgium are among the earliest Cenozoic avian remains from Europe and include the oldest temporally well constrained records of the Gastornithidae, as well as tentative records of the paleognathous Lithornithidae and the Ralloidea. Another assemblage from the middle Thanetian of Templeuve, France contains multiple bones of the Lithornithidae as well as a record of the Pelagornithidae. Specimens from the latest Thanetian of Rivecourt-Petit Pâtis, France are tentatively assigned to the Ralloidea and Leptosomiformes. An assemblage of 54 bones from the middle Ypresian of Egem, Belgium represents at least 20 species in more than 11 higher-level taxa. Well-identifiable specimens are assigned to the Odontopterygiformes, Galliformes, Messelornithidae, Apodiformes, Halcyornithidae, Leptosomiformes, and Coraciiformes. Further specimens are tentatively referred to the phaethontiform Prophaethontidae and to the Accipitridae, Masillaraptoridae, and Alcediniformes. These three-dimensionally preserved fossils provide new data on the osteology of taxa that are otherwise mainly known from compression fossils with crushed bones. They also further knowledge of the composition of early Paleogene avifaunas of the North Sea Basin. Paleocene avifaunas of Europe and North America appear to have had different compositions and only a few taxa, such as the paleognathous Lithornithidae, are known from both continents. This suggests that the very similar early Eocene avifaunas of Europe and North America are the result of early Cenozoic dispersal events. The well-represented small galliform species from Egem most closely resembles Argillipes aurorum, an ignored galliform species from the London Clay. The tentatively identified fossils of Accipitridae and Alcediniformes would represent the earliest fossil records of these clades. The birds from Egem include few seabirds (Odontopterygiformes, cf. Prophaethontidae) and is dominated by terrestrial species (Galliformes, Messelornithidae). Arboreal birds (Halcyornithidae, Leptosomiformes, cf. Alcediniformes, Coraciiformes) are less abundant and aerial insectivores (Apodiformes) very scarce, which either indicates a taphonomic bias in the composition of the avifauna or particular paleoenvironmental characteristics of the nearshore habitats in that area of the southern North Sea Basin.

Inproceedings Reference Paléoenvironments et climat au cours du Tardiglaciaire en Vallée Flamande (Belgique): l’enregistrement multi-proxy haute résolution du paléolac du Moervaart
La région de la Vallée Flamande (Nord-Ouest de la Belgique), est une zone relativement plane de basse altitude située à la limite Sud de la couverture sableuse de la grande plaine du Nord-Ouest de l’Europe. A la fin du dernier Pléniglaciaire et au cours du Tardiglaciaire, de nombreuses dépressions lacustres et zones humides s’y sont formées. Ces milieux sont d’importants écosystèmes pourvoyeurs d’excellentes archives pour l’étude des changements paléoenvironnementaux depuis la dernière glaciation, ce qui fait de ce secteur des Flandres une zone d’intérêt particulier. Pourtant, bien que des analyses polliniques y aient été ponctuellement réalisées, très rares sont celles menées en conjonction avec d’autres indicateurs, et leurs résolutions temporelles très faibles restent inadaptées pour mettre en évidence des changements brefs et abrupts comme peuvent l’être certaines crises climatiques. Afin de mieux comprendre les processus naturels intervenus au sein de ces écosystèmes sensibles de la Vallée Flamande, une étude basée sur une approche multi-proxy a été récemment entreprise sur la période du Tardiglaciaire. L’objectif fondamental est d’aboutir à une reconstitution détaillée et quantitative des environnements passés à haute résolution temporelle en relation avec la variabilité climatique au moyen d’indicateurs indépendants. Pour ce faire, une tranchée de 70m de long a été creusée dans la partie la plus profonde de la dépression du Moervaart, un des plus grands paléolacs d’Europe. Plusieurs séquences, montrant une stratigraphie contrastée (marnes lacustres, gyttja, dépôts tourbeux et passées sableuses en alternance), sont en cours d’analyses par le biais d’indicateurs biologiques (pollen, NPP, macrorestes végétaux, charbons, diatomées, ostracodes, mollusques, insectes), sédimentologiques (LOI, susceptibilité magnétique, granulométrie, densité), chronologiques (datations radiocarbone et OSL, téphras) et géochimiques (isotopes). Cette contribution se propose de comparer les résultats livrés par la palynologie à ceux issus des autres champs disciplinaires. Il s’agit ici d’évaluer si la végétation et les autres indicateurs ont évolué de manière concomitante et simultanée et d’identifier les indicateurs paléoenvironnementaux les plus sensibles aux conditions climatiques régionales.

Inproceedings Reference Paleogenetic analysis of cat mummies from ancient Egypt
Situated at the crossroads of Africa, Asia and Europe, Egypt is considered one of the two potential cradles of cat domestication (Felis catus). Here, cats most likely developed their relationship with humans with a dual role. In fact, on the one hand Egyptian iconography depicts cats as skilled hunters, and on the other hand as companion animals, quietly sitting under the chairs of noble people and as guardians of the deceased (Yoyotte & Vernus, 2005). Egyptian cats were object of a cult dedicated to the goddess Bastet, and from the 1st millennium BC until the 4th century AD were mummified as votive offerings. Previous ancient DNA (aDNA) investigation (Ottoni 2017) showed that cats in ancient Egypt possessed two maternal lineages commonly found in modern domestic cats. Haplotype-C, which spread all over the Old World since Classical Antiquity from Northern Africa, and haplotype-A, which was associated with an earlier cat dispersal from the Levant during the Neolithic. DNA from cat mummies represents a key tool to unravel the role of Egypt as a possible independent centre of domestication, despite the fact that the retrieval of aDNA from mummified tissues has greatly been challenged by DNA preservation. Here, we show the preliminary results of aDNA analyses conducted on more than 50 Egyptian cat mummies from Beni Hassan and Gourna (Luxor), dated to the Greco-Roman period. By comparing different methods (e.g. single and double stranded genomic library construction), we provide an extensive case for screening DNA preservation in arid regions, and within different tissues, such as hair, claws, and petrous bones. We also explore the potential to gain novel insights on the dispersal of domestic cats from Egypt in Classical Antiquity through mitochondrial and genome-wide data.

Inproceedings Reference Paleogenomic insights into cat domestication in ancient Egypt
Situated at the crossroads of Africa, Asia and Europe, Egypt is considered one of the two potential cradles of cat domestication. Zooarchaeological evidence points to cat-human relationships as old as the 4th millennium BC. Later, cats were object of a cult dedicated to the goddess Bastet, and from the 1st millennium BC until the 4th century AD were mummified as votive offerings. Previous ancient DNA (aDNA) investigation showed that cats in ancient Egypt possessed two maternal lineages commonly found in modern domestic cats. Haplotype-C, which spread all over the Old World since Classical Antiquity from Northern Africa, and haplotype-A, which was associated with an earlier cat dispersal from the Levant during the Neolithic.

Inproceedings Reference Paleogenomics of European wild and domestic cats
Zooarchaeological and genetic evidence from the last two decades demonstrated that domestic cats originated from the North African and Near Eastern wildcat, Felis silvestris lybica. The commensal relationship between humans and cats most likely started 11 thousand years ago (kya) in the Neolithic Levant. More recently, ancient mitochondrial DNA (mtDNA) evidence suggested that domestic cats spread to Southeast Europe as early as 4400 BC, however their dispersal to the rest of Europe is controversial due to the paucity of data. Furthermore, complex scenarios of admixture between domestic and wild populations (e.g., the European wildcat F. s. silvestris and the Asian wildcat F. s. ornata) may have taken place across time, thus leaving a mtDNA-based reconstruction unsatisfactory. Here we show the preliminary results of our paleogenomic investigation from more than 150 cat remains from European archaeological sites dated from 15 kya to the 18th century AD, with a peculiar focus on the Mediterranean area. By screening the samples for endogenous cat DNA content, we provide a framework of ancient DNA preservation in cat remains across time and space. Furthermore, by generating complete mtDNAs and low-coverage nuclear genome data (ranging from 0.2- to 1.4-fold), we were able to refine the chronology of cat dispersal in the Mediterranean region, and to address questions around potential admixture patterns between wild and domestic cat populations. Our paleogenomic dataset lay the foundations for future and more in-depth analyses aimed at understanding the factors determining the evolutionary success of the domestic cat.
