Help me ID these Shark Teeth from Florida

[Limestone]

Hi all, I recently bought a small lot of shark teeth, all said to be found in Florida and have been trying to identify them.

These are some of them, am I doing alright? 

 

The ones labeled "Lemon?" have all a small notch on the middle of the root, is this a good way to identify them?
 

Ruler is in mm

 

Thank you!

Alright so here's a summary of your guesses:

 

Tiger: yes

Hemipristis: yes

Lemon: yes

Dusky: not necessarily as these can also be Bull. Technically they are considered to be in the Requiem category (Carcharhiniformes order) but what you have appears to be Bronze Whaler. These teeth are more difficult to identify because most Requiem teeth (minus Tiger) are similar.

 

The last four appear to all be Hammerhead.

 

Here is a detailed guide of Miocene teeth from Calvert Cliffs:

I definitely agree. Those dusky looked a lot like bull shark teeth to me.

Tiger - yes

Hemipristis - yes

Lemon - the middle tooth and the bottom right tooth, the others are lower Carcharhinus teeth (the upper center and the lower left are lower bull shark teeth)

Dusky - the upper left and middle, the lower middle is a bull, the others I can't positively id from the picture

Unnamed - 4 Caribbean reef shark
