Xampylodon

Xampylodon is an extinct genus of cow shark. Fossils assigned to this genus are known from the Late Cretaceous and early Paleocene. Xampylodon was erected in 2021 after a revision on the taxonomy of hexanchid fossil teeth, and includes four species (X. dentatus, X. loozi,X. brotzeni, and X. diastemacron), most of them previously included in Notidanodon.
