Rostral Tooth?

Recommended Posts

I wonder if this is a rostral tooth (and from which species)? It comes from Venice Beach, Florida and is 2.1 cm long.

Thanks for your help.

Need better pics to tell.

Fossils are simply one of the coolest things on earth--discovering them is just marvelous! Makes you all giddy inside!

Try shooting your pictures outside on a sunny day with the macro setting (looks like a tulip if your camera has that setting). If not, back up a little so they are in focus. Check your pictures on your computer to see if they are really in focus. That little view screen can fool you sometimes.

I replaced it with an improved photo.

In all fairness, this photo is not easily useful for ID purposes. It is too dark and out of focus. The photo advice you have been offered is good. Hopefully, your equipment will allow a better photo.

I followed the advice. Here are the pics.

Doesn't look like a rostral tooth. I'm thinking maybe part of a sting ray spine.

Good eye! I see where you get that; the central "channel" is like that at the base of a stingray spine.

That was my first instinct, too. I also vote for fragmented stingray spine

This is a rostral. I sometimes finds pieces like that here in Texas that are worn down bits of bone or even wood. Hard to tell by the pic still but I agree with everyone that it's not a rostral.

Here is what a stingray spine looks like. No likeness with mine.

Just the basal bit, I think, and it's pretty banged-up.
