Cnemidiastrum stellatum from Poland

Following up on my previous post, here is another sponge that I think is Cnemidiastrum stellatum. It is from near Zalas, Poland and is also from the Jurassic (Oxfordian stage) like the previous specimen.

These are views of the sides of this conical shaped specimen.

I'm guessing the large hole on the side is the result of another creature living within the structure of the sponge?

Cnemidiastrum rimulosum sponge from Poland

I've not displayed many sponges on this blog with the only other instance being these specimens from the Waldron Shale. Below is a specimen from the Jurassic of Poland. I purchased it from a seller on E-bay. I think it's classified as a Cnemidiastrum rimulosum but I could be wrong.
