A new mosasaurine specimen (Squamata, Mosasauridae) from the Upper Cretaceous of Antarctica with comments on the Weddellian diversity of Mosasaurinae
Mosasaurs were globally distributed throughout the Cretaceous oceans, including those surrounding Antarctica. A mosasaur humerus (IAA-Pv 819) from upper Maastrichtian beds of the López de Bertodano Formation of Antarctica is phylogenetically recovered in a mosasaurine polytomy as a close relative of...

| description | Mosasaurs were globally distributed throughout the Cretaceous oceans, including those surrounding Antarctica. A mosasaur humerus (IAA-Pv 819) from upper Maastrichtian beds of the López de Bertodano Formation of Antarctica is phylogenetically recovered in a mosasaurine polytomy as a close relative of Plotosaurus beninsoni and Mosasaurus spp. Comparisons between IAA-Pv 819 and other Weddellian mosasaurs reveal differences indicating that morphological disparity and taxonomic diversity of Antarctic mosasaurines may be higher than previously recognized.
