Wrangellian Posted April 6, 2013 Share Posted April 6, 2013 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.

And nice specimens, especially the etched one at top. Context is critical. Link to comment Share on other sites More sharing options...
Rob Russell Posted April 11, 2013 Share Posted April 11, 2013 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. Finding my way through life; one fossil at a time.

Rastellum Posted April 16, 2013 Share Posted April 16, 2013 I´m still investigating this fossil.I tried to take a picture of the structures close to the sponge.Anyone recognize this? Link to comment Share on other sites More sharing options...
Wrangellian Posted April 16, 2013 Share Posted April 16, 2013 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 Link to comment Share on other sites More sharing options...

Rastellum Posted April 17, 2013 Share Posted April 17, 2013 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 Link to comment Share on other sites More sharing options...
Wrangellian Posted April 17, 2013 Share Posted April 17, 2013 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.

FossilDAWG Posted April 18, 2013 Share Posted April 18, 2013 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. Don Link to comment Share on other sites More sharing options...

Rastellum Posted June 12, 2013 Share Posted June 12, 2013 A Spondylus shell is almost covered with sponges and other fossil elements. I found it recently at Ivön ,Sweden . Age-Cretaceous,Campan. Almost the same structures as in Cliona cretaceous from Lyme regis Link to comment Share on other sites More sharing options...
Wrangellian Posted June 13, 2013 Share Posted June 13, 2013 Interesting - looks like all kinds of things were boring into that shell! incl the Cliona, but I wonder what would produce those long 'burrows'... Link to comment Share on other sites More sharing options...
