Is this Phacops 100% real or a composed trilobite
Liamo posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hey everyone, I have this specimen and i have serious doubts that it's a classic case of a composed trilobite. Here are the photos :

Hello, I am very interested in collecting trilobites and so far I nearly have one from every order (except Agnostia and a questionable Redlichiid), but though I feel I am fairly knowledgable on them overall, I am embarrassed I cannot tell the difference between species such as Phacops, Reedops, Adrisiops, Drotops, Morocops, Austerops, and Chotecops. Species like Hollarops or Morocconites are easy to tell because they have the spines or spikes though their body looks very similar. Usually when I buy trilobites they are labelled but the ones I have gotten as gifts or from rock shops are generally unlabelled. Some are easy to tell due to context (Chotecops are generally preserved in pyrite, Drotops generally being huge,) but Phacops and Reedops?! To me, they look identical, and I've heard the best way to see is counting eye facets, but several of mine have only poorly preserved or partial eyes. I also recently acquired a pair of labelled Adrisiops and I heard that they are referred to as a 'smiley Phacops' but I am not sure where that comes from. I also think the Proetid Gerastos looks quite superficially similar to all of these species, especially when poorly preserved, but I think I can tell that one apart due to it's smaller eyes and different glabella. On top of that, I am very concerned I have some fakes from the time when I was younger and did not know very much about looking for casts or composites and those can have all kinds of crazy things going on that are not in 'real' trilobites. I will try to factor out the suspicious trilobites when comparing my collection. Are there any other context clues or morphology I can look for on these similar species? Comparison photos would be nice to see the visual differences if there are any! Thank you to anyone who helps!

Localities in the Virginia Area
Andúril Flame of the West posted a topic in General Fossil Discussion
Hello everyone, This is my first posting on TFF (although I've been lurking on the forum for a while) and I am excited to be joining a community centered around one of my main interests. I have seen that this forum houses a very kind and helpful community, and I was hoping that some may be interested in helping a - very new and inexperienced - fossil hunter. I will be in the Charlottesville area for Labor Day weekend and I am in search of any tips for finding fossils in that area or general locations where they might be. I am willing to drive up to 3 hours to other locations in Virginia or locations in West Virginia, North Carolina, or Maryland. I have heard that there are some fossils in parts of George Washington and Jefferson National Forests in Virginia and I would be very glad to hear where I can find fossils there and if a permit is necessary to hunt for invertebrate fossils in that location. I am most interested in hunting for fossils from the Ordovician, Devonian, and Carboniferous periods, but any fossils would be great. I greatly appreciate any tips or information! -

Hello everyone, I just adopted a new trilobite and could use help identifying it. I believe it is a phacops Speculator, but I don't want to make any assumptions.

Manhatango formation VA fossil expedition 10/2021
Rexofspades posted a topic in Fossil Hunting Trips
Hi all, me again. Went on an expedition with my dad to show him what I do on my free time . Did some research into nearby formations and saw a promising one was in Gore VA. After casing the place in google maps dad and I arrived there at highway 50 we started on the road cut across from the meeting place. The formation seemed promising from the road, but after finding only the same old brachiopod molds and crinoid stems I saw it as a bust. Not deterred, I set on doing a little more follow up research and found that the Legendary store was nearby. After relocating we started to look and our luck turned around for the better. I bagged two of the biggest and best preserved Trilobites so far. And Dad found some weird things splitting shale that I had no idea what they could be.. Pictures below, any comments, corrections or ID's would be appreciated. This trilobite has a funny story attached to it. I spotted it laying fossil side up in the scree a foot away from my bag after slipping. After laughing at the sheer coincidence of it all I said that this is a lesson to check every rock you can when fossil hunting. on the cliff itself I found this one after splitting open the rock a bit revealing the tail of a trilobite. after careful Extraction, I wrapped the piece in tinfoil and cleaned it up at home. after some light prep work I was giddy to find out that this was a mostly intact enrolled trilobite. while the Cephalon was missing, the thorax and tail were present and folded onto each other. this is easily one of the better pieces I have found. next come the mysteries I have no solid idea if these are anything good or not but I figured I would ask you folks.

Two Inch or 5 cm Phacops Eldredgeops rana from Penn Dixie! Great! Hey, wait a minute.
Biotalker posted a topic in General Fossil Discussion
Penn Dixie Fossil Park in Hamburg, NY is known for small but plentiful Eldredgeops rana and aside from a rare mortality plate, finding a complete 2 inch specimen is a big deal! So imagine my excitement when I uncovered this. OK, not entirely complete because I messed up the extraction a bit. But this unfortunate character managed to lie down on one pleural lobe, and get squished literally laterally. All three pics are the same trilobite, with the third picture being the classic dorsal view. Hath this nonconforming fellow no sense of the future? How common is this in your experiences?

Hi members. I am a new member and developing a collection. Currently I am looking at a sample I am seeing online. They have incorrectly identified as Barrandeops. I have one and this definitely is not that species. The one I am displaying has no eyes. It comes on a matrix with other specimens, but this one picture is the best of the group. I would appreciate if someone can identify this Moroccan fossil. It is not smooth at all, or are the others.

Hi, I'm trying to classify this trilobite, could it be phacops speculator or morocops ovatus? what is the difference? Thanks.
-
Hi there folks, So, I bought this trilobite from a Morrocan seller and I would like to know the species if possible. It came tagged as Phacops redops, but I couldn't find much information on this species. Is it correct? Found in Atchana Issimour, Morroco.

It was a pretty good week fossil collecting I managed to make it to Penn Dixie Tuesday and Friday. A few of us Canadians had the place to ourselves both days Tuesday was an interesting day, three of us went Mike, Greg and myself and we all ended up with heat stroke. The temperature topped out at 39 Celsius and then you add in the humidity factor and it was low 40's. Stupid weather for collecting but we all found some very good stuff. Greg found a huge plate that I cut down in the field for him to about 12 inches by 12 inches. It would appear to have 4 complete prone E. rana on it . It currently sits in my basement waiting to be prepped. I do not have a picture as of yet but if I get his permission I will post one. Mike as usual is the greenops whisperer and he found 2 or 3 relatively complete and large greenops at the top of the blocks in the main Penn trilobite layer. I was having a reasonable day I probably had 20 to 30 enrolled or partially enrolled trilobites in the bucket along with a very nice Pleurodictyum americanum (a tabulate coral) . I only find a few of these each year at Penn and always take them home because they prep up quite nicely. I was getting a bit frustrated that both Mike and Greg were finding prone rana's including Greg's spectacular plate, when my fortunes changed with one split of the rock. For those of you that have been collecting with me you know that my style is to spend the morning breaking out huge blocks from the main trilobite layer with big prybars, wedges and chisels and then I split for the whole afternoon. We were working a large bench and had gotten to the state where all the blocks were locked in because of convoluted dome structures and the lack of natural cracks. The blocks that day were coming out about 200 to 300 pounds and about 12 to 18 inches thick. Eventually I would resort to the diamond gas saw and create some weak areas that we could exploit, but back to this story. In frustration with the heat and three guys not being able to get the next block out I just took a chisel and a 5 pound mini sledge and took my frustration out on the rock. Well to my pleasant surprise off popped a piece of matrix that clearly had 2 nice bugs in it. Wow one strike of the sledge and the fortunes of the day are totally changed. I always tell people who are collecting with me to keep at it, your are only one strike of the hammer away from having an amazing day. Unfortunately I did not take any pictures in the field my phone would not let me it said the battery was over heated. Here is ta picture of the shard about 1/2 hour into prepping. What you cant notice in this picture is that there is a 3rd bug buried to the left, I was just able to see the edge of a pygidium from the side. For once I got lucky and it was not just an isolated pygidium. Here it is probably an hour into the prep Prep was pretty standard using a COMCO air abrasion unit at about 30 PSI with 40 micron previously used dolomite, utilizing .025. .015 and .010 tips. Very little scribing was used on the piece because was quite thin and looked to have weak spots that were stabilized with cyanoacrylate and dilute vinac in acetone .Anyway for your viewing pleasure here is a series of pictures of the completed bugs. The plate has no repairs or restoration and the bugs are lying in their original positions. Going into my collection besides the "Perfect Bug" I found earlier this season.

Trilobite authenticity
pugrockprincess posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hey everyone! New here. I have a lovely collection of trilobites and have recently purchased a large Devonian Phacops (according to description). He's over 14cm long as you can see by the photo on my hand so I wanted to check its authenticity. I've noted the nice eye detail which I know can be hard to fake. It's a VERY smelly fossil though (actually making me sneeze). Almost a cross between plaster and laundry detergent. Is there anything that could cause this if it's genuine? I will assume it's had small cosmetic enhancements but I cannot find any cracks on the matrix etc. Not even sure what the matrix is made of but it's a glittery beige. Also, would this be a phacops or would it be classed as a drotops? Thanks in advance!

Alrighty folks, I know the trilobite "fake versus real" is almost a cliché around here, but I thought I would ask any how. I bought this several years ago online...and it was advertised as a "phacops trilobite from Morocco". (Oh, I can hear the groans). LOL. So after the fact, I did some research: It has the detailed eyes and nose, it has the supposed common fracture through the "trilobite" and the matrix, and as far I can tell, I don't see any casting "bubbles". Sooooo, a probability of real, fake...or inconclusive? If it's real...cool, if fake...oh well I learned my lesson. Henry

Hi, I spotted this trilobite,pretty sure its a phacops, online for a relatively cheap price. I was wondering If it was real because it looks really good and large. He put a lighter for scale on the picture (guessing its 10 to 15cm) What do you think? Regards

From the album: MY FOSSIL Collection - Dpaul7
Phacops Trilobite Fossil Morocco Middle Devonian 393-383 million years ago Phacops is a genus of trilobites in the order Phacopida, family Phacopidae, that lived in Europe, northwestern Africa, North and South America and China from the Early until the very end of the Devonian, with a broader time range described from the Late Ordovician. It was a rounded animal, with a globose head and large eyes, and probably fed on detritus. Phacops is often found rolled up, a biological defense mechanism that is widespread among smaller trilobites but further perfected in this genus. Like in all sighted Phacopina, the eyes of Phacops are compounded of very large, separately set lenses without a common cornea (so called schizochroal eyes), and like almost all other Phacopina, the articulate mid-length part of the body (or thorax) in Phacops has 11 segments.

Phacops, is this real?
Spinosaurus posted a topic in Is It Real? How to Recognize Fossil Fabrications
when i was surfing over the internet i found this beautifull phacops. but i don't know a lot about these things. so does anyone know if this is real. i saw this other trilobite, it's from the same seller, but the tail looks a bit fishy. thats why i just wanted to know if the other one is real too. this is the fishy one, the tail doesn't look right.

Drotops Megalomanicus found it mislabeled and under priced at the mall today at a random booth, was a very unexpected pleasure measures somewhere around 5.3-5.4 inches, the condition is not to bad.

Real Morocco Trilobites or not?
Golem posted a topic in Is It Real? How to Recognize Fossil Fabrications
HI guys, I know Morocco fossils are a general no no for entry level folks like me. However this particular piece caught my eye and I quite like how it looks. It has 2 Phacops and 1 Paralejurus on the same matrix Would be great if I can get some more insight from the experts on this forum. Thank you.
