Sharks could be facing extinction over the next couple of decades. Human interference is largely to blame for the species interference. Overfishing of sharks has increased as the global demand has ...

Tooth of the extinct C. lawleyi from Italy. Many other species formerly described in this genus were moved to the fossil genus Rolfodon in 2019. Chlamydoselachus and Rolfodon can be distinguished from one another by their tooth morphologies. Rolfodon also survived the Cretaceous-Paleogene extinction event but went extinct during the Miocene.
