Shark tooth identifying

[SandiTN]

I have numbered under the teeth of that helps me to identify them.

 

[Fin Lover]

2, 4, 7, 9, 13, 14, 16 & 17 look like types of carcharhinus to me (I could be wrong, the pic is kind of dark).

1 & 10 - sand tigers

15 - P. contortus

 

Hopefully, others will correct me where I'm wrong.

THANK YOU! 

Now for the dumb question, what is carcharhinus?

[Meganeura]

Echoing what @Fin Lover said - but also 3 & 15 are tigers - 3 specifically is Galeocerdo cuvier, 15 is Physagoleous contortus. 5 looks to be Carcharodon hastalis - AKA the Mako shark.

Oh, and 13 is probably a Lemon shark, not carcharhinus.

Carcharhinus is a genus of sharks including sharks like the Dusky, Bull, Reef, Bronze, and many others. They're all incredibly similar in shape and size so are very hard to distinguish.

I posted the numbers UNDER the teeth. Not on top. Are you sure of the ID?

I'M I'm sorry but I don't know the names you're using. I'm new to this and need names in "Layman's terms" I guess. Lol

Yes - I'm sure on the IDs. P. Contortus is called the "Tiger-like" shark, as it's shaped similar to a tiger shark tooth but is a different genus. Galeocerdo is the genus for tiger sharks, cuvier is the common tiger shark - same one that's still around today.

@Meganeura, I think I added a couple more while you were typing. I agree on #3, as I was looking up the name of it when you posted.

Thank you so much! Maybe I will learn something. I love hunting for teeth when I go to the beach

Sandi, for the most part, these ARE the layman's terms.

I see that! Also gonna posit that #11 is an Angy - it's got the Otodus root for sure. What's your take?

@SandiTN - #11 looks to be from the Otodus genus, most likely Otodus angustidens - one of the ancestors to the Megalodon. Are these South Carolina finds? Florida? North Carolina? it'll help narrow down the possibilities. 

[Fin Lover]

Thanks @Meganeura, I didn't mean to include #13 as carcharhinus.  I agree with lemon.

These Are Georgia finds. All but number 1, that was Alabama

Don't worry - you'll learn em. They're really just scientific names for the animals - for example, the Great White shark's scientific name is Carcharodon carcharias. Carcharodon is the genus (Shared with other sharks, like Carcharodon hastalis - #5 in your picture), while carcharias is the species. C. hastalis is technically called the "Giant White" among other names.

Okay - then it could be a Meg, could be a Angy. I'm going to say Angy due to the fact that the root extends past the blade and looks like it could've had cusps - which Megs do not have.

[Fin Lover]

I had to post and then add to it to be able to answer before @Meganeura could swoop in, and he still beat me on several responses. 

 

Not sure on #11, as I don't see any cusps.  Maybe a closer, better lit picture would help.

For my own learning, what makes you say between Meg, and Angy, and not Chub?

[Meganeura]

@SandiTN can you take better pics of #11, #12, and #6? Both sides, with bright light.

Again with the posts while I am still trying to answer previous questions.  I need to learn to type faster on my phone.

Soooo...#5is a Great White????

I'm no expert - I've only found 1 chub - but chubs seem to have a shape much more similar to Megs, like the root doesn't leave room for cusps necessarily, they kinda just exist there, while Angys have roots that extend past that main blade.

Giant White. Ancestor to the Great White. #12 may be a Great White though - need better pictures to tell.

I Will try to get better pics in a bit. 

You guys Have been more helpful in the last 15 minutes than I've gotten in a year!

For example - 
Chub:


Cusps just come out of the blade here, you could easily smooth over them with wear.

Angy:


Remove the cusps, and you have a root that extends out past the blade.
