Hello from Baltic Sea! In Svetlogorsk only one find this time. This is Porifera, i think. I don't know the age yet. Found her among the ferruginous sand. It is a sponge, but very fragile. By how did she survive all this time? Especially after falling off a slope...
Inside, they have an interesting layered structure.
The place of the find is marked with gloves. She fell from about 7 meters.
