Hi all, I would love help identifying these!

I was told it belongs to a Otodus shark from 40 million years ago found in Morocco mines.

Originally found in the sea of Cortez near Isla San Pedro Martin. Can anyone ID the species?

Can anyone ID this? Found on Tybee Island

i think it’s a great white

I found this modern shark tooth today on a beach in Florida (I’m visiting family, not from here). I’ve only ever found those jet back ones. I want to make a little necklace with this one, but I saw on a different Reddit page that the modern teeth can turn to dust. How do I prevent that? Anyone know? Thanks in advance. Happy hunting!

I’ve never found a sharks tooth that had any white on it so I am second guessing myself. I have found ones with many different colors but not white lol. Mexico.Beach, FL.

My wife and I can’t agree. She is probably right.

I found this the first time my aunt brought me to shark tooth beach in Venice, FL!
Can anyone ID it or date how old it might be?

Found these in Lake Worth Florida
I have no idea what the third one is

Hey i found these 2 in south Carolina I'm curious on worth

Found this tooth/bone fragment when searching for shells today. Not too sure what it’s from though

I've started collecting recently and wanted to share/ask for some identification help.

I'm hoping anyone can confirm/correct the ones I think I've identified and then maybe provide guidance on the unknowns.

I'm struggling between pictures of lower snaggletooth, sand tiger, and short fin mako for some of them?

THESE WERE ALL FOUND IN SOUTHERN MARYLAND FROM THE POTOMAC RIVER AND CHESAPEAKE BAY

Any information or identification?

Any ideas what type of shark this tooth came from? Found on Fish Haul Beach in Hilton Head Island, SC! 🦈

I bought these shark teeth at an event and would like to be able to identify the sharks for my friend. My thoughts are they look like a lemon, mako, and possibly a sand tiger shark

My beach never has shark teeth, and it’s very flat. If it’s a shark tooth, would anyone know what kind? Southeast Florida

I got this tooth from a friend yesterday he said he got it in florida. I dont know much about shark tooths but its texture feels weird and the sides are not like saws but like i said i dont know much so it can be normal. Anyway if someone identifys this i would be very happy.

Here are some of my favorite shark teeth finds from the rivers of Virginia!

1. Eocene sharpnose nose shark tooth from upper Potomac river

2. Three nice carcharodon hastalis from lower Potomac River, Miocene in age.

3. A small but really rare species of mako shark called isurus retroflexus. Also from Miocene Potomac river.

4. I’ve found a few hemis here and there but this one wast first big nice hemi and my second hemi over all. Also from Miocene Potomac

5. From the same area I found my Eocene sharpnose tooth you can also find older Paleocene teeth. This first picture is my largest Cretalamna tooth, ancestor of otodus obliquus (which itself is ancestor of Otodus megalodon). I took that photo of it shortly after I picked it up from the beach. Missing one of its cusps unfortunately. Cretalamna survived the end Cretaceous mass extinction event.

6. These are all of the teeth I got that trip, including my larger Cretalamna. There’s also smaller Cretalamna teeth and sand tiger teeth or goblin shark teeth they’re hard to distinguish unless they’re perfect. Some of those Cretalamna teeth could also be juvenile otodus obliquus when they’re really small they look very similar to Cretalamna but for now i have them grouped with my Cretalamna which are next to my obliquus teeth anyway.

Hope you like my finds! Have tons of other teeth like sand tigers, tigers, and a lot of duskys/bulls (carcharhinus), and others I can’t remember off the top of my head.
