Are all of these all sand shark teeth? Bought for me for Christmas

[KingSepron]

Got all these shark teeth for Christmas, are they all sand shark?

[KingSepron]

Aight so I'm gonna take a shot at this I guess.

 

I think the first column are all sand sharks.

 

I think 1-3 of second column are sand sharks, 4 is Otodus I think. 5 is sand shark.

 

1-2 on third column are sand sharks, 3 is Otodus. 4-5 are sand shark.

 

1 is sand shark (?) on fourth column. Rest are sand shark too.

 

All fifth column are sand shark. (except maybe first one?)

 

1-2 and 4-5 on sixth are sand shark, 3 is ???

Does that seem right?

Aight I’ve narrowed it down to these five which i think are not sand shark teeth.

[KingSepron]

So basically I’m only looking for IDs for these five please.

The thing is they are missing a lot of their identifiable features ie whole root shape and all cusps so a species is basically impossible (though maybe an expert could do it) but to me they are all sand tiger shark teeth with the possible exceptions of the 1st and 2nd teeth in the last photo

I’ll send better photos in a bit

Ok so here’s my reasoning:

 

This one seemed too bent, and the length of the tooth seemed to be roughly the same as the top part (can’t remember it’s name)

 

[KingSepron]

This one seemed to widen too quickly. I have a lot of sand shark teeth and it didn’t really match up with the other ones i had.

[KingSepron]

This one seemed too bent, and has 2 smaller teeth to the side

[KingSepron]

Looking at it again, this one is probably sand shark

This one however just screamed Otodus to me
