Demopolis Formation ID help

[fossilsonwheels]

We got a lot of 20 shark teeth from the Demopolis Formation, Frankstown location I believe. I basically separated them by those I think are Goblin teeth and those that I think are not lol 

 

Pic 1 I believe these are Scapanorhynchus teeth. 

 

Pic 2 and 3. My best guess on this one is Paranomotodon. I am very unsure of that ID.

Pic 1 Serratolamna? 

 

Pic 2 & 3 Serratolamna 

 

I am fairly confident both of these teeth are Serratolamna but I could be wrong.

Cretalamna ?? 

 

Not it at all sure on this one.

Your Anomotodon is correct. I think the last tooth is a lower Serratolamna. Not sure on the other two, one has an asymmetrical root like Serratolamna but has odd looking cusps and the other (first one) looks more like Scapanorhynchus.

I agree.  Pic 1 is an upper Scapanorhynchus.
