About the Cliona, are these not just the mould of the holes drilled by the sponge? And the lines connecting them, I assume these were the cracks in the shell before it dissolved?

Not that this diminishes the appeal of the fossil in any way - the only way it could be better would be if you had the actual sponge with spicules etc, but I doubt that can ever be found.

Yes, since they are now thought to be poriferans. And nice specimens, especially the etched one at top.

I just found this Astylospongia a couple of days ago at my local stomping grounds. In twenty five years of hunting the formation I've only found three complete ones. This being the third.

Sugar Run formation - Silurian.

That's part of the large shell. Are the sponges on top of this or is there matrix/etc in between? can't tell from the pics

Thanks for your answers.There is a matrix of 3-4mm between the shell and the impression of the sponge.The matrix is white just above the shell (0,2mm).And then the matrix is gray.It´s possible to take a better photo in the weekend ,taking advantage of the sunlight during the day.Thanks again for the answers

Yes so if I can say before seeing more pics it looks like this piece mostly consists of the space between the valves, or at least between 2 valves that got deposited close to each other.

Here's a neat little sponge from the Lake Valley Formation, Mississippian, New Mexico. Don't have a proper ID for it yet. You can see fairly large spicules in patches. It's about 4 cm long.

Hexactinellid would be my guess. I didn't see anything formally described besides random spicules. Congrats on the great find!

Thanks for checking, Scott. Maybe I'll contact Barry Kues about it, he's the authority on New Mexico invertebrate paleontology I think.

It's somekind of a print of the sponge...can you try to prep it out? May be another part of the sponge preserved good enough to see its surface structure and to determine it

I acquired this from Geological Enterprises Inc. several years ago. I wanted one on hand so I could be familiar with the sponge in case I ever found one.

Now that is most definitely a top-drawer specimen.

A Spondylus shell is almost covered with sponges and other fossil elements. I found it recently at Ivön ,Sweden .

Age-Cretaceous,Campan.

Interesting - looks like all kinds of things were boring into that shell! incl the Cliona, but I wonder what would produce those long 'burrows'...
