Dear MARMAM community, On behalf of my coauthors, I am pleased to announce our recent article published in The Journal of Systematic Palaeontology
New Pliocene right whale from Belgium informs balaenid phylogeny and function Guillaume Duboys de Lavigerie, Mark Bosselaers, Stijn Goolaerts, Travis Park, Olivier Lambert & Felix G. Marx ABSTRACT Right whales (Balaenidae) are the most distinctive family of extant baleen whales, thanks to their highly arched rostrum, tall lips and robust body shape. They are also the oldest, originating as much as 20 million years ago (Ma). Nevertheless, their fossil record is patchy and frequently understudied, obscuring their evolution. Here, we describe anew stem balaenid, Antwerpibalaena liberatlas, from northern Belgium, adding to the rich but historically problematic baleen whale assemblage of the Pliocene North Sea. Within right whales, Antwerpibalaena forms a clade with two previously described extinct genera, Balaenella and Balaenula. The holotype preserves much of the postcranial skeleton, and informs the emergence of typical balaenid traits like fused neck vertebrae and paddle-shaped flippers. Its size is intermediate between that of extant right whales and most of their extinct forebears revealing a more complex pattern of balaenid size evolution than previously thought Provenance : Courrier pour Windows 10 -- L'absence de virus dans ce courrier électronique a été vérifiée par le logiciel antivirus Avast. https://www.avast.com/antivirus
