Megalichthys mullisoni tooth

This looks more like a Hyneria tooth to me.

How did you identify this?

I have several of these labeled/ID'd as Hyneria as well, which I think is the correct ID. Mine is substantially more broken though, so good find regardless!

@Fossildude19when I found it I had the same thought. We found a large plate with layers of M. mullisoni scales and a larger jaw with a couple teeth (in a museum) and that tooth. Doug Rowe was apart of the excavation and informed me that Megalichthys scales get striations similar to Hyneria with age. 

Thanks Sarah!
