Hi everybody.
I found that piece in a pile of rejection from an ancient quarry, among inocerams, and traces of ammonites.
I really have no idea of what it can be : ammonite chambers, sponge, algae, else... ?
It is about 3,2 cm long and 1,7 cm wide.

Location : South-west of France.
Stage : campanian.

Thank you in advance for your help.

Sophie.

Definitive a spongebody, I think.
But it's hard to put the right name on these sponges without examining the skeletal network closely. With a body composed of anastomosing tubes with such thin walls you can think about Eurete or Plocoscyphia but there are some more possible species.
I should leave it on 'Hexactinellid sponge' first

Thanks Spongebob.

I broke it open to see how it was Inside.
Here are the photos.
