Brachiopod maybe?

[pambosk]

Hello, another one from Ayios Athanasios hills, 5km from shore, this one I already prepped,

it's a bit confusing, at some point there seems to be a shell over a shell, when I tried to prep the inside, there were white and red parts, also a small round shell part, so I stopped till I get your advice. 

Is it half a brachiopod again or something else? 

It is white/pearly with light shades of grey as opposed to

   which was more brown/orange and bigger

 

Here are the photos the size is 38mm from one far side to the other, yet the one side is slightly broken so ...

additional data.  around that in 5 m²  I found another 6 pieces of shell material, one of them seems to match the above sample in some ways.  I prepped a bit the inside of that one. also at some point they felt like clicking together so I took a few shots. 

here u go

 

the interesting / matching shell:

 

 

the rest of the shell parts inside and outside:

 

 

finally combination of the two matching ones:

I do not see enough to make an id on this.

Now someone will come along and prove Me wrong.

(Who will it be this time?)
