New records of the tylosaurine mosasaur Hainosaurus from the (Late Cretaceous) of central Poland

Two isolated mosasaur teeth, one from the upper Campanian of Piotrawin, the other from the upper Maastrichtian at Nasilow (Wisla River valley, central Poland), recently described as Plioplatecarpinae sp. A and Plioplatecarpinae sp. B, respectively, are reassigned to the tylosaurine genus Hainosaurus Dollo, 1885. The present record thus adds to the list of Hainosaurus species known to date from elsewhere in Europe (Sweden, Belgium and England).
