Fossile Germany

[Paläontologie]

I have found this fossile in the Quarry in Hannover.

One of the fossile peces is 5cm long and 5cm wide

First i thought it is an Sea urchins inner Pece but it is to large for this 

sorry my english isnt the best

Inoceram?

Welcome to the Forum from Arizona.

 

If it is an inoceramid shell, then it should be calcite and have a columnar prismatic structure. Does the fossil have that structure? See second photo from R. L. Squires blog: http://rsquirespaleo.blogspot.com/2018/07/?m=1

That's  a clam or oyster shell. I find ton of them here in Dallas creeks.  Some of them are 24 inches long or wide.
