A little jaw bone for ID

[IndianRiverSonrise]

Thanks for all the help I get here. If I might ask one more....

Do you think this fossilized jaw bone is from a fish or little land mammal.

It was found on a florida beach.


Sorry for the questions, but I just don't know anything about this stuff.

My guess would be Lutra, the river otter.

My guess would be alligator jaw bottom leftside!

I'm pretty confident that it's a jaw from a mammal.
