Are these ray teeth/jawbones?

[Ludwigia]

Hi. I just acquired these fish teeth on our favorite (by default) online auction house. The seller gave the information that they are sub-fossil, Pleistocene in age 17,000 years old and from Calle Majanicho on Fuerteventura, one of the Canary Islands. Unfortunately he couldn't identify them for me. I'm thinking they come from some kind of ray. Any ideas as to genus or species?

These are pharyngeal tooth plates from parrotfish.
