    Partial trilobite identifiable?

    I bought a large box or various fossils that I believe were part of someone's estate off of an online auction site. This is a portion of trilobite and unfortunately there was no label to go with it. Hopefully there is enough detail in the picture for someone to narrow it down a bit. Let me know if better pictures are needed or a close up of the eyes.or something else. Thanks
  2. Haven't been on here in years, but i figured you guys would enjoy this. I was lucky enough to find the most complete Bufoceraurus cephalon of this species ever found and donated it to Gerald Kloc for prep and description. I can't wait to see it prepped! It's from the Platteville formation, WI.
  3. I was wondering what kind of minerals would make this cephalon from my collection have this color.
  4. From the album: Missouri Trilobites

    These last few months have been very generous with its fossil output so far. This specimen's head is about 7.5mm long and is what I consider to be very rare. I have only ever found 2 heads in the upper Winterset limestone. In the future, I plan to clean it up a bit, but for now, he stands with his glabella exposed.

    Big cephalon

    I split out what looked like a promising Ameura trilobite a day ago. After the split, I took the plate home to use a rotary tool to trim the matrix down. Then I used a sewing needle to do some detail work. It turned out not to be complete, as it's right cheek is missing. This specimen would have been around 3 inches if all there, maybe next time!

    Platteville Cephalon

    Found this today in the Platteville formation, SW Wisconsin. In the Mifflin member specifically. From what I see, it looks like a trilobite cephalon? I'm thinking Thaleops ovata. (Cap for scale)

    DSR Trip Part II

    Hello again everyone, sorry for the delay between Part 1 and Part 2. I went through some more material from DSR and I've made some pretty awesome finds. I might have enough specimens for a Part 3, but I still have to go through more material. The same goes for the Penn Dixie part, I've barely touched it yet and still need to photograph the finds. To kick Part 2 off, here is my best DSR find yet! A nearly complete (unfortunately disarticulated) Echinocaris punctata!!! My kitten Indy for scale The Echinocaris has one of the spikes on its tail visible, and both valves are present. Another Phyllocarid, a Rhinocaris columbina! The reverse side shows another half, possibly from the same Rhinocaris? This cute little cephalon is one of my first Eldredgeops finds at DSR. Here's the Dipleura heads I've found so far (excluding the one from the previous trip report), This one is one of the largest I've found yet, it's 3 inches wide! This cephalon was a real heartbreaker. The other half of it was stuck under 1 1/2 - 2 feet of overburden This one is upside down I think this is a juvenile Dipleura cephalon, but I'm not 100% sure. I'll have to clean it up to be sure. Now onto the misc finds This is one of the largest Goniatites(?) I've found here, it popped out of the matrix on the way home but it should be able to be glued back. I feel like the cone shaped fossil in the center of the piece might be a Hyolith, but I don't know for sure. A lone crinoid stem, it'd be cool to see what it looks like when prepped. Not sure what kind of fossil this is, possibly a devonian putty scraper? Here's some Brachs and Bivalves from DSR, I'm not 100% sure on the ID's so if I'm wrong please correct me on it. Goniophora chemungensis? Paraspirifer acuminatus? Mucrospirifer consobrinus? Big jumble of brachs (maybe some Bivalves too?), cool golden sheen on it. I don't think it's pyritization. Assorted brachs Devonochetes coronatus? This is on the back of the possible Hyolith piece shown above. M. mucronatus? Large brachiopod and bivalve hash plate Probably the biggest Bivalve I've ever seen, let alone found. ID unknown Orthonota undulata

    Crushed Pseudodechenella cephalon?

    From the album: Fossildude's Middle Devonian Fossils

    Crushed cephalon of what I am assuming is a Pseudodechenella trilobite. Found in July, 2020. Smoke Creek, West Seneca, NY. Hamilton Group Middle Devonian

    Very interesting trilobite Cephalon?

    Hi again! Found this trilobite cephalon today with what looks like a pygidium under the glabella. Not sure of the species yet, is this a pygidium that got preserved under the glabella or is this possibly the internal structure?

    Buchava trilobite

    Hi, I found this cephalon in 2010 at the Buchava site in Czech and would like to know more about it (Ptychoparioides ...?). I hope you can help me to identify. thanks in advance, Mark van Smaalen Wageningen, the Netherlands

    Tiny cephalon ID

    I was going through some rocks I found last year and came across this tiny cephalon I never noticed before. I believe this is Ft Atkinson formation , Ordovician. Cephalon measures only 1mm and is covered in tubercles. I'm wondering because of size would this be considered protaspid? Any help with ID appreciated.

    Thaleops? Cephalon?

    Found this one in Bowmanville (Mid Ordovician, Cobourg? Formation) last weekend. My best guess is Thaleops laurentiana cephalon but id like to have a better idea what it is before I attempt any more prep. Have not tried yet but probing with air abrasion looks like it will be difficult since the matrix is full of calcite or some other crystals. @Malcolmt @Kane @Northern Sharks
  13. From the album: Finds From the Ordovician -488 to 443 MYA-

    From the Collingwood member of the Lindsay (Cobourg) Fm.

  15. Hey everyone, I thought that I would talk about trilobite anatomy. I have been using some complicated terms, and I want to make sure that we are all on the same page. So please watch the movie and enjoy!
