fifbrindacier Posted September 25, 2017 Share Posted September 25, 2017 Hi again, here is the last piece i found from the cenomanian that could be sponge. It is calcitized because it fizzes with vinegar, so i think it also could be a strange concretion. If it's a sponge, in the book on the fossils of Charentes-Maritimes i have, the closest looking-like sponge photo i found is a Doryderma sp..

abyssunder Posted September 26, 2017 Share Posted September 26, 2017 It could be coral in a diagenetic transformation. The growth of the new material is arranged in the shape how the septa was at their original state (radial), and that reminds me of expansion process in the silicification of the geode fossils, but maybe not so far in time. Very interesting specimen! In other words, I would say, It's geodized. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

fifbrindacier Posted September 27, 2017 Author Share Posted September 27, 2017 Thank you, i mostly took it because it had that funny look.

abyssunder Posted September 27, 2017 Share Posted September 27, 2017 A good reference regarding to the geodized fossils might be this one. The widely expansion from the center to the periphery of each element (in the specimen in question) is clearly in a growth measure which makes possible the way of diagenetic processes. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
