Coral? Sponge?

Hi all,

Was wondering if anyone has any ideas on this one. I'm thinking maybe some kind of coral or sponge, but I'm not sure. Found in Truth or Consequences, NM. There are quite a few Pennsylvanian marine fossils in the area. It's pretty heavily mineralized, but if you look carefully at the photo with the scale, there are two dark strands running across the center that are segmented.

 

Thanks for any input!

Not a sponge, I think the black is a crinoid lumen but I could be wrong.

Favosites?

I agree with favosites

It could be a chaetetid sponge. These are common in the middle Pennsylvanian (Moscovian/Desmoinesian)

Context is critical.

Good suggestion, found this diagram of a chaetetid

That was actually the first time I'd heard of the Chaetetid.  Interesting structure

I was just looking at that, too. Very similar, but the structure on the top of mine seems more regular. Almost perfect hexagons. I'm leaning towards the fasovites consensus.

Favosites itself became extinct in the Devonian and I don't think there are Carboniferous favositids that are very similar and with such a small tube diameter.

Chaetetes is extremely likely and abundant. I don't think yours is uniformly that regular and patches of Chaetetes are a good match.
