Heptranchias howelli, the sevengill shark, is a nektonic carnivore in the genus Heptranchias. It is an extinct species that ranged from 37.2 to 20.43 Ma.[3]
Teeth from Heptranchias howelli have been found in Europe. An antero-lateral tooth and an upper lateral tooth were found in Faxe, Denmark in 2014 . In addition, two incomplete antero-lateral teeth and an upper anterior tooth are kept in a private collection.[4] A 2015 study in Trelde Næs yielded a complete lower tooth, 17 incomplete lower teeth, and an unidentified broken tooth.[5]
