Lower cretaceous gastropods

[Nipponites]

Hello,

I have recently found some gastropods in a village of Teruel, East of Spain. They are from Albian Cretaceous. Visiting the local museum has not solved my doubts about their identification, they had some gastropods as mine, but, to my unexperienced eyes, there were identical specimens under different labels: Paraglauconia picteti, Cardium Voltzi, Glauconia lujani, Orthostoma verneuilli, Turritella vidalina and Cassiope luxani.

I am sure it is not Cardium Voltzi, as  it is a bivalve, I have doubts about Glauconia lujani and Cassiope luxani being synonims, and I haven´t been able to find anything about Turritella vidalina or Orthostoma verneuili.

I have separated them in 4 groups according to their ornamentation, I hope someone can identify them:

Ruler is in centimetres and inches.  

 

 

1st group, two rows of lumps per whorl:

From left to right, 1A, 5A, 2C.

 

 

2nd group, two spiral ribs per whorl:

8B.

 

 

3rd group, a spiral rib and a row of lumps per whorl:

From left to right, 4D, 3B, 4C.

 

 

4th group, smooth surface:

From left to right, 5D, 6D, 8D.

 

 

Thanks in advance for your help!
