Lithuanian fossils, what are they?

[AndersonNoe]

 

 Hello everyone!

 

 After looking at some findings, I spotted some stones, which look the very same. Stones, which usually should be glacial erratics! All three stones look the same. Does that mean, they came from the same place? I'd have some hope, it could be some mushrooms of some time, since they all have the very exact same built, but I think, that's not even possible? 

 

 After a farmer went over the field, plowing, I found a broken stone, from which there peeped out a long, round fossil. It does not really look like the rugosa I constantly find. Does somebody know, what it could be? Maybe a scaphoboda?

 

 Another stone has some imprints on it, which I hoped to be tiny fish scales. But I assume, my hopes are too high. Does somebody have a clue, from what it could originate? Maybe aphrocallistes alveolites?

 

 The last photo is somewhat of a no fossil thing, but I keep on finding so many shells on the fields. Does somebody maybe have a theory, how they might have come so far inland? Birds maybe?

 

 Thank you in advance

I see a probable nautiloid and a bryozoan.

I suspect the fossil in the second to last photo is a section through some kind of a recepticulitid.  The highly uniform arrangement of the individual elements is characteristic of recepticulitids and little else.
