ID requested: Eocene micro shark teeth from Tielt Formation, Egem (Belgium)

[ziggycardon]

Hi everyone, yesterday I recieved a lot of shark teeth, 20 of which came from the Egem Clay, Tielt Formation, Egem, Belgium that date back to the Ypresian, Eocene. 
The teeth are very small sized so I tried a macro lens to take pictures (I apologize for the not always clear images), and I believe most belong to Physogaleus secundus. 
But I wanted to share my thoughts on the ID's of the teeth and see what your imput would be as I am not an expect on Eocene shark teeth. 

Tooth 1: Physogaleus secundus

 

 

Tooth 2: Physogaleus secundus

 

 

Tooth 3: Physogaleus secundus

 

 

Tooth 4 Physogaleus secundus

 

 

Tooth 5: Physogaleus secundus

 

 

Tooth 6: Physogaleus secundus or Galeocerdo?

 

Tooth 7: Physogaleus secundus

 

 

Tooth 8: Physogaleus secundus

 

 

Tooth 9: Physogaleus secundus

 

 

Tooth 10: Physogaleus secundus

 

 

Tooth 11: Abdounia minutissima or Scyliorhinus sp.?

 

 

Tooth 12: Physogaleus secundus

 

 

Tooth 13: Physogaleus secundus

 

 

Tooth 14: Physogaleus secundus

 

 

Tooth 15: Physogaleus secundus

 

 

Tooth 16: Physogaleus secundus

 

 

 

Tooth 17: Physogaleus secundus? Not sure, looks a little different in morphology then the rest.

 

 

Tooth 18: Physogaleus secundus

 

Thank you in advance!

This one is probably a lateral Abdounia. I agree with your other Physogaleus IDs.

Thank you for your input! I know it looked different than the rest.
