What is this bigger shark tooth?

[Letsurf]

I just moved to FL recently and my dad is visiting from MO. We decided to try to find some sharks teeth so headed to Manasota Key to hunt on the beach. We were there for a few hours and found a bunch of smaller teeth. On the way out I found this larger one but it looks really old and rounded compared to a lot of the black ones I've seen. This is only the 2nd time I've been shark tooth hunting here so I have no idea what I'm doing. Is this a megeladon tooth? Any way to determine the age of this one compared to the black ones?

It looks like a very worn megalodon

Looks more like a hoof core than a tooth.

Can We see picture of the wide end straight on?

100% a meg. You can see the faint outline of the bourlette.

OK, not a hoof core.

That is really, REALLY worn, and yet it is a desirable specimen. Why is that?

When I first picked it up I thought it was a rock because of the color and texture. It looks petrified so I thought it may be older than the shiny black ones. I figure it is less desireable than one with a nice shape and details.

No, seriously. I really meant it. I would want that in my collection as a example of the extreme wear it can exhibit and still be identified as a fossil.

So it's that bad huh lol. I just thought it was common. Maybe that's why I found it because others may have passed it up? Is it common to find larger teeth on the beaches like Manasota Key and Venice? I was starting to get the impression that to get a bigger one I needed to go to the rivers or creeks and do some exploring.
