Over the years I have found it difficult to pass up a nice trilobite. Several were without identification or background information; I gambled that I would be able to identify these trilobites using information on the internet (images mostly). I am attaching images of those that I believe to be Devonian trilobites. I would most sincerely appreciate corrections and/or further species identification from those with more expertise. The first image is of a trilobite that I acquired at an antique store in Alaska that was liquidating an estate with a private museum. Through comparison with images on the internet, I have tentatively identified it as an Acanthopyge trilobite. The second image is of a partially entrolled trilobite that I have preliminarily identified as an Asteropyginae trilobite (through images on the internet). The third image is of a Crotocephalina gibbus trilobite from the Devonian in Alnif, Morocco. The fourth image is of a Gerastos trilobite from the Devonian in Zguid, Morocco. The fifth image is presumably a Metacantina trilobite from the Devonian in Morocco. The sixth image is presumably a Paralejurus trilobite from the Devonian in Morocco. The seventh image is presumably a Phacops trilobite from the Devonian. The eighth and final image is of a Proetus granulosus trilobite from the Devonian in Morocco. Any further information/discussion about these trilobites would be appreciated.

Hi, I think this trilobite looks like Phacops smoothops, it's eye facet similar Phacops smoothops eye fomula. But I think the smoothops genal angle is more rounded. So I'm not sure that it is smoothops. Is it smoothops? And, in Phacopidae, if the eye facet is correct, can i specify it, if other features are little different?

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!

Is this Phacops a real specimen? Or is it fake?
75millionyearsago posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi! I bought this trilobite, which i identified as a Phacops- i bought it at a small mine that sold rocks, small gems, and fossils. I bought this [price redacted], but now have begun to doubt its authenticity.
