Resumen:
Duck-billed dinosaurs or hadrosaurs are a very common family of
dinosaurs in the Late Cretaceous of North America and Eurasia with
rare occurrences in South America. Here, we report the first hadrosaur
recovered in Antarctica from sandstones of late Maastrichtian age, Vega
Island, Antarctic Peninsula (Fig. 1) during a joint U.S.-Argentinian geological
and paleontological field expedition to the island. This discovery
supports the hypothesis of a dispersal route between southern South
America and Antarctica in the Maastrichtian.
