Help with a bone valley fossil ID, Central Florida

[jforbes]

Hello all, 

 

On a bone valley fossil hunting trip, I turned up a fossil I was a bit unsure about. My best guess was a sawfish rostral tooth. Let me know your thoughts and some bonus pics at the end!

 

Here is what I believe to be a porpoise tooth (the other side is a bit busted up)

 

 

And here is a riker frame of some of my better bone valley shark teeth I found.

 

 

 

Thanks for looking!

The texture seems wrong. In fact, I'm not positive this is even a tooth .

+1 for rostral tooth

Could this be an illustration of why  Ischyrhiza is considered a sawskate ?

Looks like a Pristis rostral tooth.

I have no input on the identification, but I do love your display, gave me ideas for my bone valley finds.

It is a Rostral tooth,  I and friends find shorter and smaller ones in the Peace River but I have long noted that Rostral teeth coming from the Bone Valley phosphate mines look almost exactly like yours...

 

Your 2nd fossil is indeed a porpoise tooth, unidentified to Genus/species.. It might be a kentriodontid dolphin fossil tooth,   Very nice finds...
