Sandalodus? Deltodus? Crusher plate tooth

[Collector9658]

I worked out a few crusher teeth this past week. These teeth come from the Deer Creek limestone. They all look pretty similar. Not certain if they are the same, or from different species of fish. The second is the smallest ive found. I know form genera is an issue with these too. Anyone have any insight?

I would call that Deltodus, although I've only found one of them so far locally.

 

I did some light research on it when I found it, some of this might help.
