Resumen:
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.
