Rhinobatos hakelensis fossil

Rhinobatos is a genus of fish in the Rhinobatidae family.^[1] Although previously used to encompass all guitarfishes, it was found to be polyphyletic,^[2] and recent authorities have transferred many species included in the genus to Acroteriobatus, Glaucostegus, and Pseudobatos.^[3]
