    Trilobite identification

    Hello everyone! I have a local fossil guy and he doesn't always get in trilobites as he specialises in ammonites. He knows I collect them so gets the odd one in from the same supplier for me to look at. Although I own many different types of trilobites I have never found this type yet, even after visiting many fossil shows. Does anyone know what it could be? Possibly an older species? Has tiny pointy dot eyes like my cyphaspis. It's quite large, maybe 12cm. I'm torn as to whether to buy it, it's not exactly a pretty one but the collector in me feels I need it! Thanks for your time!

    Paulding OH proetid pygidium

    I was working out a trade with a fellow member and they very graciously pointed out that this is not an Eldredgeops pygidium as I thought, but instead a proetid pygidium. From the Silica Shale in Paulding, OH. The only proetid from Paulding my searches turned up is Pseudodechenella. Any thoughts?
  3. I don't buy many fossils and most that I have bought, or that have been bought for me, were from gift shops and the like when I first started collecting. However, for my birthday a couple of years back, my wife surprised me with this plate of a pair of Russian trilobites. They are Asaphus Intermedius and Asaphus Punctatus. I was overjoyed! From my meager knowledge at the time, I thought that they were completely real. I knew to look out for fakes (i.e. carvings, plaster/resin cast, etc.), or heavily composite specimens from other areas, and since these came from Russia, I thought I was in the clear. My wife also spoke to the seller, and from my understanding, they were very helpful and seemed sincere. They also disclosed that some of their specimens do have a little restoration/repair work, such as the crack on the back of my plate and had a money back guarantee. Fast forward a couple of years... With my birthday coming up and me working on setting up a new display cabinet I got to thinking about this plate of trilobites. Then I remembered that these were from Russia, and that I read somewhere that things coming from there tend to be heavily restored with resin and the like. I have also read that you can tell by using a UV light (black light) to shine on them and any resin used will glow. I don't have one handy, but will pick one up the next time I'm out to test with. So I wanted to poll the community and see what people thought. Are these real? Fake? Heavily restored? I just realized that I didn't include some form of measurement or something for scale in the pics... Each trilobite is roughly 3.5 inches long x 2 inches wide (9 cm x 5cm). The whole plate is 5 inches x 6 inches (12.5cm x 15cm). Front view: Back View: Notice the glued crack... Side Views: Possible restored area on pygidium? Appears to be a slightly different shade than rest of trilobite. Resin? I can provide more pics if needed. And include a scale.
  4. Hi all, i'm buying that trilobite but i'm not expert in cambrian morocco trilos. That one seem real with no restoration but i'm not sure. Also not sure about species. Can you help me? Thanks

    Found in Mulbring, NSW. Possible trilobite?

    I found this small fossil that appears to be a small partial trilobite. Can anyone confirm? Also, i apologize the pictures are so bad. Its so small and flat my camera can't cope.
  6. Short visit (1-2 hours) to famous locality near Las Vegas. I wish we would do better home work because some interesting trace fossils were identified only after we watched the video recordings. Perhaps, our "movie" will help you not to miss them when you will visit this unique place. It was a family Christmas trip, by the way. Also, if you know the species, please help with ID.

    Trilo Whole or Molt?

    I had a group of families fossil hunting through Eagle Bluff Environmental Learning Center on Saturday and one family found this incredible, and very large, trilo molt, or is it a whole one? How I wish I would have found this! Beautiful specimen! To me, on site, this appears to be the actual shell of the 500 mya trilo, that smooth and detailed! ID PLEASE Sorry, no more pics, they took it home to WI. Ordovician Fillmore County, MN Stewartville member of the Galena Formation
  8. So, finally on the last leg of my trip and headed home tomorrow. Am thinking ahead about trying to prep my DSR Dipleura. Doubt I could but does anyone think it would it be possible to flip the cephalon to straighten this bug out? There is about 3/8 inch of matrix between at tip of cephalon. Otherwise the plan is just to re-glue the pygidum break, cleanup the cephalon and enjoy my beginners luck Dipleura

    Isotelus

  10. Removed from a stream boulder, this Greenops like pygidium is larger than most complete Devonian trilobites from NY. Im not sure to what the exact species is so Im just calling it Greenops like. The age is Middle Devonian from Livingston County, New York. This could have been a near 5 inch bug if complete. Based on the dimensions of the largest complete Greenops sp. I have found in the collected area. From near spine tip to spine tip wide - 2.3" (58.50mm) Around 1.6" - 1.7" long (42mm)
  11. Hello, fellow fossil people! I am extremely new to the fossil scene and have almost no experience identifying authentic versus real fossils. I recently received a large trilobite fossil as a gift from my parents. The seller claimed that it was an authentic Moroccan trilobite, but I'm not so sure. Any information on the fossil's authenticity and/or identity would be greatly appreciated!
  12. Hello everyone, It's been a while since I've started a topic on the forum; but over time, it has occurred to me how many of our forum members have spectacular specimens of Chinese trilobites. I hope to start this thread to showcase and celebrate the amazing trilobite fossils that come from China, contributed by no other than our very own. Chinese trilobites have been relatively underlaid in the trilobite collection world by the Moroccan material and Russian material. But with a jaw-dropping diversity and rarity of trilobites, China's trilobites may make up for the incredible 3-D preservation seen in Moroccan Devonian trilobites and Russian Ordovician trilobites. China's Cambrian trilobites are quite famous and popular, ranging from the god-status trilobites of the Kushan formation in Shandong, to the unique trilobites of the Sandu formation from Guangxi, to the ancient trilobites of the Chengjiang and Guanshan fauna in Yunnan... the list goes on. Perhaps we may even start to hear Chinese Cambrian, Russian Ordovician, American Silurian and Moroccan Devonian in the future amongst trilobite collectors! Regardless, I hope the collectors of the forum would be willing to share their fossils to us, no matter how they are. The more the merrier!
  13. I recently bought this large trilobite fossil at a rock/fossil shop in Texas. After doing research I found that their are apparently Alot of fakes out there. The fossil itself has the same grainy mineral characteristics as the rock surrounding it when a flashlight is shined on it. The tiny sandy mineral deposits sparkle. I did a small bite test that an article I read suggested to do and it did not feel like resin. It was very gritty and the same texture as the rock that surrounds the fossil. Please help me if you can. Sorry it is only 1 picture. It wouldn't let me upload any more.
  14. I found this trilo for sale online, seller claims the species is Parahomalontus however I cannot find much info on this species. Can anyone help me ID this trilo and tell whether or not it is fake? Thanks.
  15. With the Belgian Asociation for Paleontology we made an excursion to the quarry at Soignies. The rock exists out of mixing layers of hard limestone and softer claystone. The quarry is rich in carboniferous fauna with corals, brachiopods and two species of trilobites. When entering the quarry we were welcomed by a young peregrine falcon who was flying next to the high stone wall, which was awesome. It was beautiful weather and the quarry contains a variety of fossils. I'm happy I was able to collect a diversity of organisms that represent the Tournaisian periode. I also found more trilobites on this day than in my whole carreer as a fossil hunter... I found exactly two pieces Caninia sp. (Michelin, 1840) Cummingella belisama (HAHN, HAHN & BRAUCCKMANN, 1985) Leptaena analoga (Phillips, 1836) Michelina favosa (Goldfuss, 1826) Calcite? Cummingella belisama (HAHN, HAHN & BRAUCCKMANN, 1985)

    Giving fossils wet look

    I only prep with hand tools at the moment so I can rarely get all the matrix off a fossil. However, when wet, the matrix is usually impossible to see and the fossil looks very well prepped. Is there a coating I can use to keep the fossil looking wet? I’m looking to try this on trilobites in particular.
  17. Newbe quastion, how do we recognize a molt of a trilobite from a whole trilobite? I got my first trilobite which I believe is a whole specimen and not a molt, but what is this that makes as understand the deference, do molted ones missing som ething? I thank you all for your help in advance!
  18. I had the pleasure of attending the recent Penn Dixie Dig With The Experts and had the opportunity to catch up with some old collecting friends and make some new ones. As one of the people helping out collectors and cutting a heck of a lot of bugs out of rock for people I had the opportunity to see most of the really awesome bugs found that weekend. Without a doubt this one found by Scylla's son was one of the best and one of the rarest finds to be had a Penn. Gus and his son were kind enough to trust me with their prize find. The bug was damaged a bit and split between two sides of the matrix. I will look at repairing some of this at the end of the prep. Regardless this is a huge bela and has remarkable preservation. This is being prepped with relatively low PSI dolomite / sodium bicarbonate mix with some minimal scribing using a Pferd MST-31 with fine stylus. At the point of this picture I have already trimmed down the counter part to make it ready for reassembly. Reassembly was by super thin cyano acrylate clamped for 24 hours

    TriloBITS

    Hi! I stopped at a rock and fossil show earlier today and I picked up these trilobite parts along with a couple other more complete pieces. I was wondering if it is at all possible to ID it only with these parts. I’m thinking the large part is an Isotelus pygidium and the separate piece on the right looks like an eye, but I’m no expert. So if any of you have ideas, send ‘em at me! From Canada, Middle Ordovician, from Colborne Quarry in Colborne, Ontario

    Proetid

    Just cleaning up a few finds from the Hungry Hollow Member (Mid-Devonian, Arkona, Ontario). I am awful at discerning between proetids based on certain fragments, so was hoping for an assist as to whether it is a Pseudodechenella or Crassiproetus. If memory serves, one has a bigger anterior cephalic brim. I can usually tell them apart if I have the pygidium (Crassiproetus has a more rounded, effaced one). I’m leaning more toward Pseudodechenella. Once the genus can be nailed down, I have a question about size ranges that I haven't come across in the literature. When measured around the curve of the glabella, I get 2.5 cm. That seems fairly large for examples I've seen elsewhere. That would have made this trilobite, whole, about 7+ cm (sag.). That seems a bit too big for most proetids I've encountered.

    McKay Group trilobite

    I recently received a nice trilobite from the Upper Cambrian McKay Group in BC, Canada. I found this little guy in the back and wanted to extract him so I could display them together. It was hard since the plate was pretty thin and the two trilobites lied on top of each of on either side. So this little guy got a little beat up. Anyways, does anyone recognize the species? I am completely unfamiliar with the McKay Group.

    1930s collection

    I got this box of fossil from auction at the low price of £21. The collection is old and dates between 1933 and 1944 . Some of the collection has labels but sadly others are lost or mixed up. Most of the locations are from Yorkshire but there is also Oxfordshire and the midlands. I purchased this lot because of the small collection of corals. The some of the corals have been cut and polished. I did re-polished most of them because they seamed to have a coating to finish the process. There is also some nice plant material from coal seams it is good to get this material from now in the Uk lost localities . Please if anyone can help me fill in the blanks I have added locations I have the labels too, Robin Hoods Bay, Leeds, Wakefield , Whitby , Buckinghamshire and Midlands. I will do a better list of locations when Mrs R gets home because I can’t read some of the hand writing. I think it is a great little collection. Thanks for looking. Cheers Bobby corals 1) 2) 3) 4) 5) 6) 7) 8)
  23. A week ago today, I took the day off work to hit one of my favorite sites, a roadcut above the Illinois River in Oglesby, Illinois. This cut exposes the Pennsylvanian LaSalle Limestone member of the Bond Formation and produces abundant brachiopods as well as occasional other fauna including gastropods, cephalopods, coral, trilobites, and shark teeth. The weather was perfect, sunny but not too warm, when I pulled up. The cut is a somewhat unstable slope of cobbles and boulders of varying size, almost all with at least some fossils in them. To get up to the slope, you have to hop across a small ditch with running water. I have a good sampling of the common brachiopods from here, so I am looking for unusual fossils when I go now. I was very happy to quickly find a piece of trilobite as I started to search the rocks at the base of the hill. (I will put pics of everything I brought home in a response post) One interesting find that I was not able to bring home was this Linoproductus brachiopod with some shell preserved and a really pretty dendritic pattern on it- it was very delicate and firmly embedded in the middle of an ~80 lb boulder. I was able to stay for 4 hours, and I felt like I gave most of the site at least a quick look. I am very happy with what I found- I was able to check off many of the rarer things I was looking for, including shark teeth, a trilobite, cephalopod material, and a brachiopod with spines attached, as well as some nice crystallized brachiopods. I will post all of my finds below.
