Notidanodon
Extinct genus of Cow shark
Notidanodon is an extinct genus of cow shark. Fossils ascribed to this genus are known from the Jurassic and Cretaceous periods. Recently, the genus underwent a major revision and was split into two after the erection of Xampylodon to accommodate the species X. dentatus, X. loozi, and X. brotzeni.[1] The genus is now known only from New Zealand, Antarctica, Africa, and South America.[2]
