title: Endemic evolution of Tethyan‐derived belemnites in North‐East Greenland: the middle Barremian <i>Duvalia</i> Event
abstract: Abstract Marine sequences on Wollaston Forland, North‐East Greenland have provided rich belemnite assemblages of Barremian (Early Cretaceous) age. Most common are belemnites of Boreal affinities, closely related to northwest European faunas. Remarkable are the findings of 47 rostra of Duvalia , a genus of Tethyan origin. In addition to Duvalia grasiana , Duvalia arctica sp. nov., Duvalia aff. silesiaca and Duvalia sp. have been recognized. Duvalia grasiana is well known from the Barremian–Aptian
