Hi, I recenty acquired a bulk of shark teeth found on the beaches of Cadzand, The Netherlands.

I think there are around 200 - 300 shark, ray and fish teeth in the bag ranging in age from the Eocene up to the Plio/Pleistocene. 

A large chunk of the teeth are common species like C. hastalis, Brachycarcharias lerichei & Striatolamia macrota teeth. 

But there are a few I am not sure about and some I don't even a clue about, so I was hoping some people here might help me out confirm my ID. 
Thank you in advance!

All the ray teeth in the bunch

Most of the cowshark teeth in the bunch, I think all of these might be Notorynchus primigenius from the miocene & pliocene

Tooth 1: 3 teeth which I believe these are upper jaw teeth of Notorynchus primigenius

Tooth 2: A cowshark that looks a little different than the rest, might this be a Hexanchus griseus tooth? (Miocene/Pliocene)

Tooth 3: The largest tooth of the bunch, due to it's size I am not really sure to which species it might belong, although I believe it might be a large Sand Tiger tooth. 

Is it an Araloselachus vorax or do Striatolamia macrota & Isurolamna affinis get this big?

Tooth 4: a small tooth with large cusps, only one like it in the bunch, the preservation typical of the eocene teeth from this location so I am guessing it is Eocene in age.

But I don't really have a clue for the ID
