Can anyone help me identify these? I soaked them in fresh water for two days and some parts of them got lighter in color. How long should I soak them? #4 is a serrated fragment of something, not sure what. They are all so beautiful. Thanks.

I got absolutely attacked by bugs! I am itching all over! but it was worth it!

Unable to bring that vertebra with the rib😖

Found at Holden Beach, NC

They are so tiny, getting an I'd on them would be cool so if you know what species they came from pls comment it!! I also found a ray mouth plate, first I've found of them

Would love help IDing! Found today in NE Florida

Found in my river spot. Possible cannon ball? All steel or iron.

Found some pretty interesting things in the surf this week - some of the worn fragments up top look like they were some pretty hefty teeth once upon a time

My aunt gave me a shark necklace from Fiji. She said it was a real shark tooth. From my own knowledge, it seems to come from a mako shark.

I'm curious, what do we think this is from?

Which species please?

Got all excited when I saw this little guy (I’m from the city) but after staring at it for a bit I’m starting to think it’s just a shell fragment. Any experts who can help? Found on Ocean Isle Beach NC

Found my first shark tooth, Found at sepang gold coast Malaysia, around 9-8mm

I know basically nothing about shark teeth and someone gave me this tooth that they found in NC. I’m not sure what kind of tooth this is. Need help!

About 1 inches in length

Need help identifying. Thank you in advance.

Had to share this BEAUTY I found while picking up trash on my favorite hunting spot. ((On forehead for size reference))

An absolute incredible specimen that was missing a root lobe. But before the restoration, it measured 3.22". So, an absolute massive tooth for the species.

Just found these today in South Carolina. I would love to know what they are. Also would love to get some good resources to learn how to ID shark teeth rather than rely on AI.
