  1. The popular collected trilobite Phacops rana is well embedded in literature for over a hundred years. Then in 1990 it was renamed Eldredgeops rana. A lot of collectors did not understand why the name change and I would like to attempt to clarify why the change. The purpose of this post is to point out the differences I have observed between Phacops and Eldredgeops and explain why "rana" is an Eldredgeops and not a Phacops. The literature on phacopid systematics is in a mild state of disarray. Authors have built on the errors of previous authors. There is no good English diagnostic descrip

    Phacops Speculator?

    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.
  4. 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 st
  5. 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?
  6. 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.
  7. Hi, I'm trying to classify this trilobite, could it be phacops speculator or morocops ovatus? what is the difference? Thanks.

    Phacops from Morroco?

    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.
  9. 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 currentl
  10. 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
  11. 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. Henr
  12. 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
  13. 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 s

  15. 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

    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.
  17. 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.
  18. Hello all- I recently acquired another "fossil" from a guy that lives in Texas who supposedly bought this piece from a reputable dealer who claimed to have done all the work on it. This is my first time collecting trilobites, and I know that so many fakes come out of Morocco. I have read the sites about how to identify the fakes, and this piece has a couple of "red flags" but if it is a fake it's very well done, and even worth what I paid simply for being a piece of "art." I can see the shiny glued areas on the phacops, and some strange coloration changes. Like I said in posts befo

    Several thoraces, two cephalons of Eldregeops Rana from what is probably the Smoke Creek Trilobite Bed of the Windom Shale. This sample comes from a creek on private land on the West shore of Canandaigua Lake in New York State Finger Lakes region
  21. 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

    Nw Ohio Trilobite

    I recently cleaned this Phacops trilobite for a friend in the local Gem and Mineral club. He found it last August in a quarry near Paulding, OH. Only flaw is a missing upper lip.

    Preparing Phacops PD

    I have by good fortune acquired a few decent Devonian Phacops trilobite specimens from the Penn Dixie Quarry in Hamburg, NY. One particular rock has a few decent Phacops embedded directly in the rock. I wanted to know what the steps are for preparing these fossils, or if I should just send them to a preparer. Please provide any advice you can. Thank you. I have a bunch of fossils and am new to the preparing process.
  24. I have a decent collection of trilobites (Phacops, Elrathia Kingi, Perenopsis) along with a new Eoredlichia that's being shipped directly from China. I also have a large assortment of sharks teeth (Bull, Sand Tiger, Tiger, Snaggletooth) from the Calvert Cliffs Maryland area, a pristine condition Ecphora (Maryland state fossil), a saltwater crocodile tooth, turritella's, quartz horned corals (W New York), porpoise teeth, shark vertebrae, dolphins bones and vertebrae fragments, and numerous other fossils.

    I purchased this trilobite from Colorado, I was told it is a Phacops but from what I read it seems a bit on the large side. Since I was told its from Morocco I questioned its authenticity but due to the damage I think it is real but crudely excavated. Any thoughts on this specimen would be appreciated.
