  1. Found this online, something about it seems off. If anyone could help me find out if it's fake I'd appreciate it.
  2. Hoya everyone I recently purchased this spiny trilobite from morroco and was wanting some help on its authenticity many thanks

    Help to ID this Dudley trilobite

    Hiya everyone I recently purchased this trilobite from Dudley, any help with the species and help with the other species on the matrix would be great, thanks.
  11. Hi, I purchased this trilobite from a rock shop. After doing some online research, I think it’s real but would like some more opinions. It passes the tooth test (feels like stone). Also, if it is real, does anyone know what type or species it is? TIA!
  12. Hello! After losing 2020, and then winter, I was finally able to get out and look around in my new area, NE Iowa and near Grant County, Wisconsin. I walked down a few rivers in the Ordovician areas, Platteville Formation, Grant County, and picked up what I think might be a Trilobite? Based on the Various publications of the region, it may be Sceptaspis lincolnensi, but this is really my first Trilobite I have found (in many years of walking along looking at rocks) I haven't cleaned off any of the matrix, just a nice scrub. I also found this hash plate nearby, I liked the Gastropod? In the cent

    Trilobite gills

    New paper from: Science Advances 31 Mar 2021: Vol. 7, no. 14, eabe7377 DOI: 10.1126/sciadv.abe7377 eabe7377.full.pdf Abstract Whether the upper limb branch of Paleozoic “biramous” arthropods, including trilobites, served a respiratory function has been much debated. Here, new imaging of the trilobite Triarthrus eatoni shows that dumbbell-shaped filaments in the upper limb branch are morphologically comparable with gill structures in crustaceans that aerate the hemolymph. In Olenoides serratus, the upper limb’s partial articulation to the body via an extended arthrodial me

    Need a QUICK ID on a Trilobite!!

    I found a tiny object locked in matrix yesterday late in the afternoon and threw it in the bucket thinking it was a brachiopod. So when I cleaned it up a little this morning, I was surprised!! My wife fell in love with this trilobite (loves anything petite) and insisted I enter the FOTM competition. I am torn between a very small Isotelus or the more likely Anataphrus vigilans. HELP so I can enter before today's deadline (for her sake!!!).

    Georgia Cambrian Mystery Trilobite

    When splitting some extra matrix from the Tibbs Bridge Road exposure of the Middle Cambrian Conasauga Formation I came across this trilobite cephalon imprint. It does not seem to match any of the common trilobites found at the site and I could not find a similar example in the various trip reports other members have posted about past visits to the site. Any help is greatly appreciated. Thank you!

    Calymene trilobite ID

    These are more trilobite segments, and one cephalon, from the Leighton Formation, Maine, silurian. I believe them to be the new species of Calymene trilobite that I found earlier, but am unsure. The first pictures are of the first specimen, numbers 1 and 2 being of the cephalon, and the third of a thorax segment that was underneath the cephalon (you can see the edges of it in picture 2): The next pictures are of new specimens. Number one and two are of a cephalon. Unfortunately, I was unaware of its existence until after it came out in multiple piece
  18. I figured I would share little bit with you guys of some of my favorites out of my collection , the Trilobites I found probably 20 years ago near Grafton Illinois while I was actually geode hunting , The corals ( I'm pretty sure they are corals) were found in Gravois creek in St.Louis ( its chock full of them) .
  19. The Paleontolocigal Society of Austin monthly field trip was last weekend - we planned to hit a couple of spots in Brownwood. Well it's a bit of a drive from San Marcos, so I decided to make a mini two day trip out of it and stay in an Air BNB (a great option for traveling these days - no shared air source like a hotel!) . So instead of just the two sites on Saturday with the Society, I headed up to Lake Jacksboro for some solo hunting! And boy was it solo.....not a SINGLE person at the site! I was astounded. Had the whole place to myself for HOURS! It was a beautiful day - 70s and sunny. I c
  20. Took a few college friends out to the Deer Lake region today. Was the first time fossil hunting for one of them and the first time finding non shark teeth for another. Checked out a couple different outcroppings, everyone took a few things they enjoyed. Here is my haul from the day (feel free to correct if I miss IDed)... 1x Eldregeops 3x Mucrospirifer 1x Leptodesma

    Early to mid Devonian pygidium ID

    Finally got back out to my site (Needmore formation outside of Winchester VA, early to mid Devonian) for the first time this year, very good feeling. Found, among other things, these 3 partial pygidium imprints. Two appear to be the same species, and I’ve found several other partials like these out here before. I know (or am fairly sure) I’ve seen this species before online but can’t place it. The third specimen I can’t place at all and as far as I’m aware, haven’t found out at this site previously. All specimens are a centimeter and change at most, can provide more precise measurements later

    Elrathia?

    Hey all, I bought this trilobite from a seller today and was wondering if anyone could help me ID it. I'm pretty sure its from Utah, and I think it's an Elrathia, but I just want to get some other thoughts or opinions. In the bottom left there seems to be part of an agnostid, but I could be wrong. The seller said that they didn't know where it came from unfortunately.

    Tiny trilobite ID needed

    Is this tiny trilobite from the U-Dig Quarry near Delta Utah a Brachyaspidion microps or is it something else? I realize that the pygidium is covered but I don't want to expose any more of the trilobite because I know that it would pop off the shale. Thanks.

    From the album: Trilobites of Minnesota Decorah/Platteville/Galena Formation

    Ceraurid hypostome. Platteville Formation (SW corner specimen) and rest are Decorah Formation. For a long time I thought it was little rolled up trilobites, that's how much the hypostome look like. Tiny .5 cm for Decorah ones and .6 cm for platteville ones. Decorah ones seem to be uncommon to common and very easily overlooked because of its tiny size. Heck I wonder how many had I overlooked over 5 years.
