Early Evolution and Paleobiogeographic Distribution of Pipimorphs Reflects the Opening of the South Atlantic
-
Pipimorpha and its crown-group Pipidae possess one of the most extensive fossil records among anurans, which extends into the Early Cretaceous in both Laurasia and Gondwana. This is probably linked to the highly aquatic lifestyle of pipids, which is probably also characteristic of early pipimorphs. In South America, pipids are currently represented only by Pipa, but the fossil record documents an evolutionary radiation of Shelaniinae (a taxon endemic to South America) in the Cretaceous; shelaniines seem to have become extinct in the Eocene. Fewer pipimorph fossils are known from Africa. Our recent redescription of the mid-Late Cretaceous (Coniacian–Santonian) taxon Pachycentrata taqueti from In Becetèn (Niger) partly fills this gap. Our new phylogenetic analysis of Cretaceous and Paleogene pipimorphs shows that this taxon diversified in a West Gondwanan block until about the mid-Cretaceous, but after that, pipimorphs show two distinct evolutionary radiations, one in South America (Pipinae), and the other (Xenopodinae) in Africa. This pattern appears to reflect the breakup of West Gondwana simultaneously with the opening of the South Atlantic during the Cretaceous. This probable vicariant pattern yields slightly different ages for the South Atlantic opening depending on the accepted topology. The tree constrained to reflect the topology of extant taxa supported by molecular data shows a last dispersal between both continents before the Cenomanian (more than 100 Ma), whereas the unconstrained topology that reflects only morphological data is compatible with a more recent last faunal dispersal among pipids. Under this unconstrained topology, the fossil record is too poor to give a reliable minimal age for this last dispersal, but molecular dating analyses suggest that this event harks back to the Mesozoic.

Annual (2024) taxonomic update of RNA-directed RNA polymerase-encoding negative-sense RNA viruses (realm Riboviria: kingdom Orthornavirae: phylum Negarnaviricota)
-
In April 2024, following the annual International Committee on Taxonomy of Viruses (ICTV) ratification vote on newly proposed taxa, the phylum Negarnaviricota was expanded by 1 new order, 1 new family, 6 new subfamilies, 34 new genera and 270 new species. One class, two orders and six species were renamed. Seven families and 12 genera were moved; ten species were renamed and moved; and nine species were abolished. This article presents the updated taxonomy of Negarnaviricota as currently accepted by the ICTV, providing an essential annual update on the classification of members of this phylum that deepen understandings of their evolution, and supports critical public health measures for virus identification and tracking.

BASE – BAsicranial Sex Estimation: An R package for sexing adult western European individuals from the cranial base morphometry in bioarchaeology and forensic anthropology
-
Sexing an adult human skeleton from its fragmented remains is a tremendous challenge in both archaeological and forensic contexts. Although reliable sex estimation methods using the os coxae do exist, as well as the possibility of performing a secondary sexual diagnosis within a funerary assemblage, it is essential in the case of fragmented individuals to set up an alternative sex estimation method based on a skeletal element that is both sexually dimorphic and has a high taphonomic survival rate. This study investigated the sexual dimorphism of the cranial base (occipital and temporal bones), through an exclusively metric approach, in 537 identified western European adults. Using logistic regressions, thirteen predictive models were built up, which yielded up to 86.8% accuracy after cross-validation and with a decision threshold of 0.70. BASE is an R package with a graphic user interface that can be used to apply these predictive models to a target adult individual (https://archive.softwareheritage.org/browse/directory/5e3e3753e1f9c360b0ddbebaa2d2b42e5d7686d9). This paper provides measurement definitions, practical details and user recommendations. BASE is a new sex estimation tool which is free of charge, fast and easy to use, and allows anthropologists to collect biological data from larger numbers of individuals, even when their skeletons are highly fragmented and damaged. This new method can certainly contribute to a better understanding of past populations and will be of considerable value to forensic investigations in today’s context of steadily rising numbers of missing persons.

Un sarcophage en plomb au contenu inattendu trouvé à Bussière-Nouvelle.
-
Le diagnostic archéologique réalisé en 2019 sur la commune de Bussière-Nouvelle a occasionné la découverte d’un sarcophage en plomb du XIXe siècle. L’herméticité de ce contenant a permis la préservation de très nombreux éléments périssables (tissus mous, textiles, cuir, bois, végétaux) qui autorise une excellente documentation des pratiques funéraires mises en oeuvre. De plus, l’utilisation d’un sarcophage en plomb implique un contexte particulier (décès loin de la commune, rapatriement, etc.) qui n’est que très rarement observé en contexte archéologique. La première approche pluridisciplinaire mise en oeuvre (archéologique, anthropologique, historique) permet non seulement de restituer le profil biologique du défunt, mais également de tenter de comprendre les raisons qui peuvent être à l’origine de ce type de pratique.
