Paleorunner Posted June 27, 2021 Share Posted June 27, 2021 Hello. I found this some time ago, in an outcrop, of the Upper Cretaceous (Cenomanian). some fragments of belemnite, which seems to me a poorly preserved hedgehog radiola, a solitary coral, (it may be a kind of placosmilia). and a curiously shaped stone, which has me puzzled, and I would like to know what it is. sorry for the photos, but I don't have a good tool to make them better.

TqB Posted June 27, 2021 Share Posted June 27, 2021 (edited) Some very nice barnacle borings (ichnogenus Rogerella) on one of the belemnites. Edited June 27, 2021 by TqB 4 Tarquin Link to comment Share on other sites More sharing options...

Rockwood Posted June 27, 2021 Share Posted June 27, 2021 The things that are shaped like little lighter than air balloons look like concretions that stand a good chance of containing fossils. 1 Link to comment Share on other sites More sharing options...

Thanks. that's what I thought, but that shape of the anchor is not like the ones that radiolas have, like the one on the left, it also has a very earthy texture. It seems to convince me more what Rockwood says: (concretion with possible fossil surprise). best regards. Paleorunner.

Thank you. is what I thought when I saw it, but that split point left me puzzled. Any advice on how to find out if there is something inside?

Thank you very much for the information, to name who produced the perforations. I knew what kind of animal produced them, but not the name. I'm glad you like them, but having several, I didn't give them much importance. although that way they are better decorated. 2 Link to comment Share on other sites More sharing options...

There are probably guides available elsewhere on this forum also. 1 Link to comment Share on other sites More sharing options...

The one on the right may be a Porosphaera globularis sponge, which occurs regularly in the Campanian. 1 Greetings from the Lake of Constance.

Thank you so much. I've done a bit of research, and I've seen photos with a lot of similarity to that type of sponge. I think you're right. 1 Link to comment Share on other sites More sharing options...
