Cretoxyrhina, from the exhibition "Sea Monsters" on Geocenter Møn.
Supervised by Mike Everhart.
Cretoxyrhina was a large shark that lived about 100 to 82 million years ago, during the late Cretaceous period. It is nicknamed ‘The Ginsu Shark’ in reference to the Ginsu knife, as it fed by slicing into its victims with its 7 cm knife-sharp teeth. The shark itself grew up to 9 m, making it bigger than today’s iconic great white shark. It lived in the Cenomanian–Campanian seas worldwide, and was among the chief predators of the seas.
Cretoxyrhina is among the most well understood fossil sharks to date. Several preserved specimens have revealed a great deal of insight about the physical features and lifestyle of this ancient predatory shark. This is quite unique as exceptional preservation of fossil sharks is rare, because a shark's skeleton is made of cartilage, which is not prone to fossilization.
