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 everybody! Today i want to kindly ask you help for the correct ID of this trilobite. My choice is Morocops ovatus but obviously i prefer to listen the ideas of experts (@piranha @Kane @Tidgy's Dad and more). I'm thankful to everyone who want to participate at the topic Here are the info: Origin: Jbel Zguilma (Foum Zguid), near Alnif, Morocco Age: Emsian, Devonian Lenght: 5.5 cm / 2.16 inches The trilobite is not in my hands, the photos are from the seller. Thanks and have a wonderful weekend!

Cool Moroccan trilobite, maybe retouched?
Max-fossils posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hey guys, Saw this very nice looking trilobite for sale at a reasonable price, so I’m thinking of buying it. However I’m curious to know whether or not the specimen may be fake/retouched/in any way artificially handled. What do you guys think? Thanks in advance!

Quite a large specimen even for this quite big species. The length given is of the animal along the centre of its back, not the diameter.
