Hi everyone,

 

I am pretty new to fossil hunting and don't know much yet. I have found lots of shark teeth over the last year, close to 100, but don't know what a lot of them are. The vast majority of my collection is #6 & #9. Those seem pretty common. I have found around 8 of #1 (the one in the photo is the largest), four of #2, two of #3, and around 5 of #7. Numbers 4,5,8,10 are my only finds like those pictured. I would love some assistance identifying these if anyone knows what they are. Please let me know if you would like close ups of any tooth. I would be happy to add some additional photos if necessary. 

 

All the best,

Agree with the previous ID and will elaborate that 1 is Isurus hastalis. Also, 6 looks like a sand tiger. A more precise species would depend where it was found. 7 might be a lemon shark. 9 is either a bull or dusky shark, which are often hard to differentiate

Assuming these are all Miocene, then:

1- Carcharodon hastalis

2- Notorhynchus primigenius

3, 5 and 10- Hemipristis serra

4- Galeocerdo aduncus

6- Carcharias cuspidata

7- Negaprion eurybathrodon or maybe a lower Carcharhinus

8 and 9- Carcharhinus sp.

I agree with Eric on his ID's

Wow you all are awesome! Thanks for the IDs! Thats more information then I imagined receiving. I'll have to develop some sort of cataloging system to keep the different species all together moving forward. Unfortunately, it is high tide when I get home from work this week and the hunting conditions are poor. I will have to wait until next week to get back out there. Good luck hunting everyone!

I also agree with Eric.  I think 7 is a lower Carcharhinus sp.
