New latest Cretaceous and earliest Paleogene asteroids (Echinodermata) from The Netherlands and Denmark and their palaeobiological significance
Three new starfish ( Skiaster vikingr n. gen., n. sp., Betelgeusia exposita n. sp., and Aldebarania taberna n. sp.), and the first fossil occurrence of Cheiraster? sp., are recorded from Maastrichtian (Late Cretaceous) and Danian (Early Paleogene) rocks of The Netherlands and Denmark.
