Is This Spirorbis?

Hallo,

I found this in the South of Sweden. I think it might be a spirorbis. Does anyone know?

Thanks! :-)

I think it's beekite.

I searched the internet for beekite, and I believe you are right! However, what is a beekite? I can't get it to translate in the Dictionary... Is it something from a bee och is it a coral of some kind?

Thank you for information! Really appreciated!

Beekite is a distinctive form of chalcedony sometimes associated with silicified fossils.

Beekite, was named after Dr.Beck, Dean of Bristol, who first called attention to it.

"Beekite, strictly speaking, is not a true mineral species, but a chalcedonic variety ofsilica, replacing the carbonate of lime of fossil organic remains by secondary silicification." ON THE OOOURRENOE OF BEEKITE IN CONNECTION WITH
"FOSSIL ORGANIC REMAINS," IN N. S. WALES
- By R. ETHERIDGE, J NR., Palooontologist. http://australianmuseum.net.au/uploads/journals/16668/1197_complete.pdf
Beekite consists of a central nucleus surrounded by not always continuous concentric rings."As a rule there are two or three rings, but any number may occur up to eight."

"It sometimes appears as if the Beekite had more readily replaced the
matrix than the fossil, and, as it thus surrounded the organism, when the
calcareous part was weathered away, the Beekite would in such cases seem
to have been deposited upon the organism." On the manner of occurrence of Beekite and its bearing upon the origin of Siliceous Beds of Palaeozoic Age - By T. M. McKenny Hughes, M.A., F.R.S., Woodwardian Professor of Geology, Cambridge. http://www.minersoc.org/pages/Archive-MM/Volume_8/8-40-265.pdf

Paul was the first with the document.

beekite is very interesting looking. It looks like it should be a fossil.

In geology we call that type of texture 'botryoidal'. Botryoidal hematite, botryoidal chalcedony, etc. It is often associated with fossil wood especially in late Cretaceous deposits.
