Need help identifying possible tusk?

[Chris22]

Hello new to the forum I found this in sw Florida recently I’m not sure if it is a tusk or possibly a tooth any help would be greatly appreciated!

Does not look like a tusk or a tooth. Fossil tusks will have Schreger lines (cross hatch pattern) this does not have it. Most likely coming from Florida this piece reminds me of worm hole or coral.

Looks like a fossilized coral stem to me.
