Heiner Posted February 26, 2020 Share Posted February 26, 2020 Hello members of this forum, I just signed here and would apriciate to profit from all this knowledge here. Even if I was a heavy fossil collector as a kid I don‘t know much about it, but it still affects me if I see something interesting. Like some time ago I bought a small side table with an interesting stone plate on it. The backside shows some engravings what I think is the explenation to the front side fossil. Unfortunately it‘s hard to read in some parts . I think that the fossil could show some hexagonaria quadrigemina Corals? Fond 1966 in the region of the Eifel wich is close to me living in Belgium. Can you help? Thanks a lot! Link to comment Share on other sites More sharing options...
mikeymig Posted February 26, 2020 Share Posted February 26, 2020 Looks more like the cross section of a Favosites (an extinct genus of tabulate coral) not a Hexagonaria (a genus of colonial rugose coral). Mislabeled in my opinion. Many times I've wondered how much there is to know. led zeppelin Link to comment Share on other sites More sharing options...

Mislabeled in my opinion. I would have to disagree, The coral very much does look like hexagonaria in my opinion as there are visible septa on the close-up of the fossil which favosites lack. I would also expect less variation in thickness and visible tabulae for favosites which I cannot see here. A higher resolution would certainly help, but from what I can see now the original ID seems good. Link to comment Share on other sites More sharing options...
Heiner Posted February 26, 2020 Author Share Posted February 26, 2020 thanks a lot so far! Maybe this picture can help in a high resolution? Link to comment Share on other sites More sharing options...
Heiner Posted February 27, 2020 Author Share Posted February 27, 2020 ...or maybe this one in a higher resolution? Also anybody knows about the meaning of the name on the plate? I suppose that it means Jean de Heinzelin de Breaucourt who seems to be a known geologist. Is maybe the history of the fossil connected to his work?

Misha Posted February 27, 2020 Share Posted February 27, 2020 I think the ID is correct, not sure about the name Link to comment Share on other sites More sharing options...

I don´t totally understand your question but this coral species was described in 1820. Jean de Heinzelin de Breaucourt seems to have lived in the 20th century.

Kane Posted February 27, 2020 Share Posted February 27, 2020 The name may be the individual who found the specimen, not formally described it. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
FossilDAWG Posted February 27, 2020 Share Posted February 27, 2020 It's not entirely clear, but I think I can some dissepiments in some of the corallites. If so, this would rule out Favosites and favor Hexagonaria. However a definitive ID would need a transverse section to show cross sections (as opposed to longitudinal sections) of the corallites. Also I think this is the most unusual method of labeling a specimen that I have ever seen. Don 1 Link to comment Share on other sites More sharing options...
