I found this actually beautiful Erbenochile in a European auction house. However, I think all the little spines on the pleural lobes and cheek spines aren't real. What do you think about that?

On a trip with some friends to an exposure of middle Devonian strata recently we found some pretty unique Mahatango fauna. I thought I’d share one of the specimens here that I recently prepped for my good friend Gavin May! The specimen below is a complete for the most part prone example of a very rare trilobite, Basidechnella kayseri. It was prepped with a air scribe, I still have to do a bit of landscaping too.

I have a partial trilobite cephalon that I collected from the Waldron Shale spoils piles at Falls of the Ohio State Park. Since it is not directly from the quarry wall, there is some uncertainty in the stratigraphy, but it is likely Waldron or the overlying Louisville Ls. both of which are right near the border between Lower and Upper Silurian. Hopefully there is enough here to give a shot at an ID. The best I can do is say it could be Metopolichas breviceps but there appear to be some differences. Hopefully someone like @Kane or @piranha or @Ken K can see enough here to have an opinion. If not, "Trilobite Head" it will be called. Thanks for any help. Here it is enhanced a bit hopefully so you can see it better. You can see by the scale that it is under 1 cm wide. My stab at an ID initially came from Halls 1879 publication on the Waldron. Below I have my specimen between the figure out of Hall (on the right) and an example of one from the American Museum of Natural History website (left). The AMNH site says this specimen is the only known complete example which just adds to my doubt on the ID, but I have not found a more common, better match. And lastly, here is a zoom in of the cephalon to hopefully show the small bumps covering it. Thanks again for any help.

Hello to all. The Acastella trilobite from my own collection. Well preserved. I tried to get close-ups of the eyes and some small details. Place of discovery: outskirts of the city of Kamenets-Podolsky, Khmelnitsky region of Ukraine. It was not possible to determine the exact age (Silurian or Devonian). Have a nice day 1.mp4 3.mp4 4.mp4

Hello, Found this cephalon in Lucas County Ohio. It looks pretty good, both eyes, etc. It would however be a significant prep job, gluing and coming in, then from the top), I would have to pay for. I'm thinking it is worth it as this seems rare. Please help me guage this. There is more of this lens to explore, so I may wait to see if I find a better specimen. Thanks

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 found some interesting specimens as I was probing soft reddish colored Rock (sandstone?) that had been dumped in a field near my house Atchison Kansas. I could be wrong with my assumption is that it's from the nearby Missouri River. A handful of interesting observations pictured here but I'm not sure about. 1) The hard oozy substance on one rock. Is that amber? 2) the half dollar sized impression that looks like it's an Amber upon another rock. Could that be some kind of plant? 3) one rock has a thin black band across it. Wondering what ancient event might be known to cause that? 4) most interesting, I found a few Trilobite looking figures. From what I've dug into so far, looks like they might bea Carolina praying mantis oothecas. I have read that these can be hard, but they feel hard like the rock, or at least close to it. Nearby I did see s momome cotton-like material that look like it could be another stage of this creature. But then again it wasn't very thick and just a little bit of cotton material there. I have the suspicion that perhaps these were more ancient oothecas partially fossilized. But that was only a wild guess. Any insights into any of the above would be most welcome. Thanks for any help you can provide.

I acquired this specimen from an amateur fossil collector acquaintance of mine so unfortunately, I don't know where it was found and when it dates to. It is roughly the size of a dollar coin.

Hi again, it has been a long time since my last post. I think I have found another trilobite Pygidium today. It is quite small so I am unsure if it is truly a fossil or just a weird rock formation. If it is, does anyone know what type of Trilobite it may have come from? I found one a few years ago and Kane said it was likely Anchiopsis anchiops. Could it be the same? Any help is greatly appreciated! I am also wondering if the rest of the Trilobite could be hiding under the matrix.

I recently bought this strange Cyphaspis from a French dealer. Due to the great diversity of species in this genus, I have not found anything about the exact species. Can you help me in this case?

Real or Fake (Drotops megalomanicus) ?
Jacobboom posted a topic in Is It Real? How to Recognize Fossil Fabrications
After recent lessons about fake Drotops Armatus, I try to be as cautious as possible when making new purchases. I recently found a really nice double Drotops megalomanicus for sell. To me, it is just too pretty to ignore. But since this is my first time seeing such specimen (two huge Drotops megalomanicus stacking together), I think it is better to ask for options before making the expensive commitment. To me, this looks like a real one because of the white line (silica vein) running across the body. But a draw back is the not so detailed eyes, which seems suspicious. Let me know your opinions!

Hi everyone! I believe I have found trilobite (or other arthropod) tracks. Photographing was challenging. They are not the best but I believe visible enough to identify…hopefully! I found this in Crawford County, IN. Any help is appreciated!

Hi? I think this trilobite looks like Keyserops megaspina. But Keyserops megaspina's genal spine is more longer. So I 'm not sure. Is it Keyserops megaspina? or other species?

So I got out of work early yesterday and headed off in hopes to find a few trilobites. I started off by finding a flexicalymene, and another. Then it happened! I found a fraction of an isotelus! I was stoked and ready to head home! On my way back to my vehicle I figured that I would look for more. I stopped and stared up the slope and out of the cornet of my eye I spot it staring out towards me! I quickly and carefully remove it from the ground, which made me even more stoked! Here are a few photos!
