Article Reference New pipimorph from the Late Cretaceous of Niger
tIn Becetèn, in southeast Niger, is one of the few mid-Upper Cretaceous (Coniacian-Santonian) fossil-iferous localities in Africa where multiple anuran taxa are known. Two of them, Pachycentrata taquetiand Inbecetenanura ragei, have been described from In Becetèn. Both are pipids, a clade composed ofexclusively aquatic anurans. Beside these two pipids, numerous isolated bones have also been referredto anurans within the site, but never referred to any known less inclusive taxa. Here we describe severalidentified cranial and postcranial bones referable to Pipidae or its stem-group, which together constitutePipimorpha. Among these elements, three cranial elements are referred to two unnamed pipimorphs.One of these has gondwanomorph affinities (pipids + South American and African extinct pipimorphs).These conclusions are supported by our phylogenetic analyses. Numerous postcranial elements are notreferable to any of the four pipimorph taxa identified at In Becetèn, although some ilia might be tenta-tively referred to ?Pachycentrata sp. The presence of at least four distinct anuran taxa makes In Becetènthe most diverse anuran site in Mesozoic Africa. It is also the first site in the Mesozoic where four pipi-morph taxa are identified. The dominance of pipimorphs in the anuran diversity of the site suggests thatIn Becetèn was likely more lacustrine than previously thought.

Article Reference From Field to Lab : preparation of vertebrate fossils from a new Barremian Lagerstätte in South Lebanon
Lebanon is renowned for its rich Cenomanian fossil deposits, but recently its Lower Cretaceous deposits have also yielded significant fossils of plants, vertebrates and arthropods. In particular, the Barremian dysodiles (oil-shale mudstone) of Jdeidet Bkassine (Jezzine District, South Lebanon) are revealing vertebrate fossils of exceptional preservation. Until 2021, several surveys led to the discovery of ray-finned fishes, turtles and two complete mawsoniid coelacanths. In light of these promising finds, a two-week excavation was organised in 2023, supported by a National Geographic Society grant and involving an international team from Belgium, France, Lebanon, and Switzerland. The soft easily delaminated shales, allowed meticulous layer-by-layer investigation. A temporary preparation lab was set up on site to stabilise specimens, alongside identification and micro-sampling for geochemical analyses. This fieldwork unearthed an impressive array of vertebrates: coelacanths, an anura, pleurodiran turtles, squamates, and 5–7 different groups of actinopterygians. The most promising specimens were CT-scanned at the RBINS, offering invaluable insights for preparation and taxonomy. The introduction of an air abrasive unit using sodium bicarbonate and iron powder revolutionised the preparation workflow—dramatically improving speed and precision while preserving fine anatomical details, reducing the need for invasive tools like needles or airscribes. Many specimens remain to be prepared, some with exciting technical challenges. Yet the combination of exceptional preservation, with advanced 3D imaging, and refined preparation has allowed improving our understanding of macrosemiid and mawsoniid anatomy. We hope these finds could soon enough be on display in Lebanon, to share this remarkable Lagerstätte with the public.

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 ANNiKEY Linear – diagnoses, descriptions, and a single-access identification key to Annelida family-level taxa
Phylum Annelida are ubiquitous metazoans found in almost every terrestrial and aquatic habitat on Earth. Historically, taxonomic studies on the phylum have been focused largely on its majorgroups, polychaetes, oligochaetes and leeches, so that while family-level keys for each group are available, no single-source identification guide exists to the world’s annelid families. Here, the first illustrated linear key to annelid families is provided and family-level descriptions and diagnoses that distinguish individuals of each family from those of other families in the phylum are updated. This information is generated from an annelid DELTA database of 334 characters and 166 mostly family-level taxa. A link is provided to downloadable software (ANNiKEY Interactive) allowing the same data to be interrogated using the open-source DELTA program Intkey, which enables both interactive identification and taxonomic query functionality. For each family-level taxon, a diagnosis, full description, links to taxonomic data at the World Register of Marine Species, illustrations of diagnostic features, and a summary of the recent literature, including a list of published keys to genera and species are provided.
