Comparative osteological study of three species of distinct genera of Haplotilapiini (Cichlidae)
- In palaeontological and archaeozoological studies dealing with tilapia remains, identifications are usually limited to the level of the tribe Tilapiini (now called Haplotilapiini). In the present study, dry skeletons of Oreochromis niloticus (Linnaeus, 1758), Oreochromis aureus (Steindachner, 1864), Sarotherodon galilaeus (Linnaeus, 1758) and Coptodon zillii (Gervais, 1848) were analysed with the aim of defining morphological characters on a series of isolated skeletal elements. Eighteen different skeletal elements that have good chances of being well preserved (and of being recognised as tilapia) were analysed, i.e. premaxilla, dentary, maxilla, articular, lacrimal, palatine, quadrate, hyomandibula, operculum, preoperculum, posttemporal, cleithrum, supracleithrum, urohyal, vomer, and the first three precaudal vertebrae. Diagnostic criteria are described and illustrated with figures. It appears from the comparative analysis, and also from blind tests carried out afterwards, that identification is possible except for the articular and the third vertebra. More accurate identification of fossil and subfossil finds of Haplotilapiini should allow a better documentation of the zoogeographical history of these taxa in the future.

Reconstructing Asian faunal introductions to eastern Africa from multi-proxy biomolecular and archaeological datasets
- Human-mediated biological exchange has had global social and ecological impacts. In sub- Saharan Africa, several domestic and commensal animals were introduced from Asia in the pre-modern period; however, the timing and nature of these introductions remain contentious. One model supports introduction to the eastern African coast after the mid-first millennium CE, while another posits introduction dating back to 3000 BCE. These distinct scenarios have implications for understanding the emergence of long-distance maritime connectivity, and the ecological and economic impacts of introduced species. Resolution of this longstanding debate requires new efforts, given the lack of well-dated fauna from highprecision excavations, and ambiguous osteomorphological identifications. We analysed faunal remains from 22 eastern African sites spanning a wide geographic and chronological range, and applied biomolecular techniques to confirm identifications of two Asian taxa: domestic chicken (Gallus gallus) and black rat (Rattus rattus). Our approach included ancient DNA (aDNA) analysis aided by BLAST-based bioinformatics, Zooarchaeology by Mass Spectrometry (ZooMS) collagen fingerprinting, and direct AMS (accelerator mass spectrometry) radiocarbon dating. Our results support a late, mid-first millennium CE introduction of these species. We discuss the implications of our findings for models of biological exchange, and emphasize the applicability of our approach to tropical areas with poor bone preservation.
