I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!

Hi I got this Ceratarges recently. I think it is better match with Ceratarges aries than Ceratarges koumalii. (I got the information from "Van Viersen, Allart & Prescher, Harald. (2011). New species of the lichid trilobite Ceratarges from the Middle Devonian in Morocco. Geologica Belgica. 14. 193-202." ) what do you think about? Seller told me that it from Hamar Laghdad, Alnif.

I've read this (https://popups.uliege.be/1374-8505/index.php?id=3421&file=1&pid=3365) paper on Ceratarges Trilobites, as I'm trying to figure out if the one shown in the attached image is a Ceratarges ziregensis (as it was identified by the seller) or a Ceratarges koumalii. From what I can tell one difference seems to be the presence of numerous smaller spikes present on the main spines of the creature in the species Ceratarges ziregensis. The spines in the image seem smooth, so I think it must be a Ceratarges koumalii - but maybe the preparation could have resulted in the smaller spikes being so cleanly missing? Any expert help identifying this species of Trilobite would be most appreciated. Thanks!

Real Ceratarges trilobite?
DatFossilBoy posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, I saw this trilobite online and I was wondering if it was real or fake. It looks like the usual replica of a ceratarges to me. It is from Morocco of course. What do you think? Here are some pictures. Maybe @Tidgy's Dad could help me since I know he knows a lot about these Moroccan trilobites. Appreciate it.- 6 replies

Ceratarges sp. and Phacops
gigantoraptor posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello Does these trilobites looks real? It's a ceratarges and a Phacops from Merakib, Morocco. The seller said there are 27 hours of work in this piece. What are your opinions? Thanks for looking- 15 replies
