abyssunder Posted December 27, 2021 Share Posted December 27, 2021 Are you sure the locality name Kalberbeg is correct? Maybe it's Kalberg? 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.

abyssunder Posted December 27, 2021 Share Posted December 27, 2021 (edited) I'm not specialist in sponges, so I could be wrong, but the first specimen reminds me somehow of Ventriculites genus (the external ornamentation and the ondulations of the wall in transverse section). Btw, it's a nice specimen!

I found this site : https://www.cfk-fossilien.de/die-schwammriffe-des-oberjura-in-der-noerdlichen-frankenalb/ It presents a list of sponges and so, i think i've found an answer for those ones : Stauroderma sp You're right @abyssunder, this one is a ventraculites This one is probably a Trochobolus (or maybe a Cypellia) For that one, on the left, i think maybe tremadyction, but with great doubts Edited December 30, 2021 by fifbrindacier 1 "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

If he's not on the field at the other side of the world, or stuck in his lab studying a precambrian sponge to see if it has spicules or not.
