| Abstract |
Species of the craniid genus Isocrania JAEKEL, 1902 are known to have been able to adapt to various ecological parameters during their evolutionary history, which ranged in the Cretaceous from the Turonian to the Late Maastrichtian. For quite some time, specimens of Isocrania assignable to the “costata group”, which were adapted to life in current-swept environments and which occur abundantly in fossil hash levels directly above the Lichtenberg Horizon (= base of the Maastricht Formation, Late Maastrichtian) at Maastricht (The Netherlands), have posed a taxonomic problem. This material is revised here, and a new species of Isocrania is erected. |
