A partial rostrum of the Porbeagle shark Lamna nasus (Lamniformes, Lamnidae) from the Miocene of the North Sea basin and the taxonomic importance of rostral morphology in extinct sharks

A fragmentary rostrum of a lamnid shark is recorded from the upper Miocene Breda Formation at Liessel (Noord-Brabant, The Netherlands); it constitutes the first elasmobranch rostral process to be described from Neogene strata in the North Sea Basin. Based on key features of extant lamniform rostra a...
