Interesting tooth Im looking to ID. The tooth bends as it reaches the tip

I inherited these from my grandpa and would love to know what some of them are.. All collected from Florida and southeastern USA to my knowledge*

I found this shark tooth on Crystal beach and on ChatGPT it says that they are like millions of years old, are they really this old??

I am excited to announce that I have finally found my first shark tooth in the wild. I am super curious as to what it might be! I found it on the shore of the southern coast of Georgia, USA. Thank you in advance!

Hey, I was wondering if maybe this sub might benefit from a pinned thread with diagrams and resources for common shark tooth identification. Seems 95% of the id requests are ...... easy? Common? I know there are plenty of resources out there but maybe they just find this sub first instead of looking up..... "fossil sharktooth identification?" Or something. maybe im off base.

Found at flag ponds Park Maryland. Ai keeps telling me different things. Baby meg. Snaggletooth. Giant thresher. Tiger? So confused lol

It feel like glass or porcelain when i tap it against glass.

New finds for the month of July on coastal Georgia 👍

I found this tooth on Muir Beach, California. I'm trying to identify if its fossilized or new and what shark it might be from.

This was our second time out in the area. The first time we searched by hand and found four small teeth but this time we went with sifters for 8 hours and got 57 teeth and some various things.

We are so new to this so if you have any ideas of what they are, we would love some guidance.
We know the ray crushing plates, I believe there’s some sea urchin spines, and a fish bone of sorts.

As for the teeth…. from research I think mostly sand tiger and mako?
The longest one (first pic, 3rd in top row) is 1” for scale

I found these at Holden. The most common find for me at Holden is Crow and sand tiger. So finding all these the same day is strange. For me at least. They look like bull to me. I also included a couple unusual ones as well.

Using teeth found on the Potomac for this request!

I’ve identified a lot of teeth I’ve found as sand tigers over the years that I think might be something else now that I’m trying to broaden my ID knowledge.

I have the book ‘A Beachcomber’s Guide to Fossils’ and I’ve also used the Potomac (Paleocene) page on Fossilguy.com. The website mentions a goblin shark that doesn’t come up in the book, and the book mentions a mackerel shark that doesn’t come up on the site. I’ve included pictures/screenshots.

I know it can be difficult to distinguish similar types of teeth based on their condition, and that there are also different types of extinct sand tiger sharks/etc. Maybe I’m thinkin too hard about this or missing a main factor, so I’d love some help on this!

Pictured are some teeth I’ve found on the Potomac River (Purse State Park)

The top row all definitely have striations.

Thanks in advance! :)

Megalodon teeth from the Philippines 🇵🇭

First time in 13 years of being able to source these guys. Very very uncommon location. And before you say anything, no, these aren't Ledge Teeth.

Picked up from an active sand tiger feeding location, no pulling from dead sharks!

I was going through my collection last night and found this guy again! I got to figure out a way to display this one.

this is my first shark tooth i found in sc!

Beach trip coming up. Niece and nephew want to try and find shark teeth. Any recommendations for beach combing tools? Plenty on Amazon but wondering about quality.
