  1. Hello all I recently got permission from my family to build a preparation room, so I'm getting some tools to finally start preparing fossils. I've got a few fossils from my own hunts that I can start practicing on, but those are all in extremely hard, sticky rocks, and often badly preserved. I would however like to get some fossils from other locations to practice different techniques, mainly with air abrasion and to get a feel with the preparation of a wild variation of fossils. I picked some fossils (mainly from the USA), that aren't too complex I think, but please correct m

    Trilobites ($$$) ?

    I have had these fossilized trilobites for many years and would like to know what they are worth… I’ve come across similar listings ranging from [prices redacted]… this seems to be in better condition than most?

    Adam's Early / Lower Devonian

    The Devonian period is known as "The Age of Fish", but could also be known as "The Age of Brachiopods." In the Early / Lower Devonian, brachiopods reached the height of their diversity towards its end in the Emsian. We see the ancestral groups occurring, lingulids, craniids, orthids, protorthids, pentamerids, rhynchonellids and strophomenids, as well as the later successful groups we have seen before such as atrypids, athyrids and orthotetids, plus the rise of spiriferids, spiriferinids and productids and the beginning of the terebratulids. By the end of the Devonian , several of these g

    Help with ID of this calymene trilobite

    Hiya everyone. I recently purchased this trilo. I’m in the UK. Any help would be great. My best guess at the moment for locality is maybe Malvern worcs.

    Name that Devonian trilobite noggin

    Alright you know the drill (because clearly you follow all of my posts here [sarcasm]): this dude is from the Needmore formation in West Virginia which makes him Devonian, specifically emsian to eifelian. I know I’ve found more pieces of this guy before but I can’t find the photos just now, if they become necessary I’ll dig them up. He’s the rarest type of trilobite I find out here though and have yet to get a good diagnosis, even when working with a professional (something along the lines of Coronura was the closest guess I think, but that was with just a glabella to work with). This piece is

    Ammonium chloride

    I am having trouble coating this Isotelus plaster cast. This is my first time attempting the ammonium chloride coating method. First I painted the cast with a thin layer of black acrylic (in retrospect, I probably should have used watercolor?). Then made a number of tries to coat the cast with ammonium chloride and was unsuccessful. I tried placing the cast above the smoke, below and directly in front of the flask, nothing worked. I'm wondering if humidity could be an issue? Has anybody tried applying ammonium chloride as a fine liquid spray or magnesium ribbon? Any tips appreciated.

    Is this a Larval Trilobite

    This trilobite is identified as a larval Paradoxides mureroensis, specifically the late meraspid stage. It comes from Murero, Zaragoza, Spain, is 0.8 cm long and from the Middle Cambrian.

    Calymene blumenbachii

    I’m interested in this C. blumenbachii “Dudley Bug” which is ex John Page Collection, collected from the Wenlock Limestone Formation, Wrens Nest, Dudley. Most fossils from Wrens Nest tend to have a dark grey appearance rather than the honey coloured patina seen here. Has anyone seen specimens with this honey patina from Wrens Nest before? I’m told that this patina has arisen from years of exposure to air and handling. Re John Page - I’m told that Page was a trilobite collector who specialised in trilobites from Wrens Nest. Can anyone provide any more info about Page or p
  9. I was browsing for some trilobites and came across this way expensive one that of course I can't afford in my craziest dreams right now. I was wondering though what is this brown part around the trilobite? It is not the same color as the rock, neither as the trilobite's exoskeleton. Could it be soft parts of the trilobite fossilized and preserved? Or something completely different?
  10. So this was bought for me as a gift. Since they are not a fossil collector and it's a Morocco specimen I assume it is probably a fake, but since it's my first ever Trilobite I thought I'd double check. Also if someone could let me know what species it is to, that would be great. As I mentioned I not collected any Trilobites befor so this is new for me. Sorry about the image quality. Best I could do with my phone.
  11. I know members can't mention specific businesses on the forum. So, what would be the best way for me to find quarries in OK that may sell unprepped trilobites. I've been tearing up the internet and am having a hard time finding contact info for places like this. Is there a, "directory" of sorts that would help me with my search? Thanks in advance!

    New to cleaning fossils

    Although I have had a lifelong (40 plus yrs) fossil collecting passion I am very inexperienced and recently took a deep dive into a 4 day excursion to the Marble Mountains looking for Trilobites. I don’t have the right words yet to describe my days there… i can’t wait to return… that’s not my question :)…. I have several pieces which I can see the fossil(s), however there is a a lot of dirt which I am afraid to brush too hard with a brush. I am looking for advice on how to clean these fossils. If photos are helpful I can post. Thank you in advance.

  14. Hi all, My sister recently purchased three trilobite fossils for next to nothing (at a thrift store), and I'm suspecting this one is fake or at least a composite. Don't see any preparation marks, and it smells like cement. Looks like it was cemented onto the grey rock. What do you guys think?
  15. The only information that I have on this one is that it's from Morocco, Middle Cambrian and Cambropallas. The piece is ~10.5" x 8. I only have the one picture, but might be able to get more if needed. As always, thanks!

    St. Leon Prone Trilobite

    Here is a trilobite I found on my first trip to St. Leon a few weeks back. Taken with an 18-55mm macro on a T6i canon. I need to work on lighting because pictures always seem to come out dull, hence why I haven't posted in awhile. I'm still working on pacifying the flaws. If I remember correctly this species is Flexicalymene meeki

    NW Alabama

    Formation: Bangor Limestone Age: Mississippian Found this location in a remote area of Alabama recently. I Haven't hunted the Bangor in awhile, so I gave it a shot. A fragmentary calyx. Northern Alabama seems to be teeming with these, as I found 8 others in a nearby locality as well. A complete, but squashed roller of a Kaskia? Fenestrella are found commonly articulated with their fans here. This was the best individual I found. My guess is these are Spyroceras? All of my nautiloids come from the Ordovicia
  18. Howdy yall! This past Sunday I met up with @KompsFossilsNMinerals to do some collecting of Ordovician trilobites in the Mohawk Valley of NY. We tried to hit a new site, but it was sketchy and the right strata weren’t all that accessible, so we then moved on to a site that we’ve both spent considerable time at. It was a pretty slow day of collecting, but we both managed to find some sweet bugs before the day was over!

    Trilobite Ids Please.

    Hello, friends! I am currently sorting through my Devonian trilobites from that rather wonderful country - Morocco! Now I picked this first one up from a shop that had a whole table covered in the same species, and boxes underneath. The proprietor only knew they were from south west Morocco, but I was fairly certain from my accrued knowledge that they were "Izi", the Amazigh (language of the indigenous Berber people) for flies as they are so numerous at some localities. This is thus likely to be Gerastos tuberculatus marocensis, and since they were cheap as chips and I haggled, I l
  20. Here is a photo of a 2 inch Calymene my wife found in Grand Isle , Vermont in October.
  21. Got looking through some of my older stuff, from years back, when I was a bit naive. I have three Moroccan fossils, or at least labeled as such. One is undoubtedly real and only its ID is in question; I'll make that a separate post elsewhere. But I thought I'd check my evaluation of two trilobite fossils. Apologies that the photos aren't better. Real? Not an expensive offering, and not apparently a rare variety for Morocco. A hot needle does not mark it. Under the loupe, there are no obvious bubbles in the surface, and there are defects that seem

    Yet another Devonian hypostome

    Hey it’s broken record Brian to ask about yet another hypostome. Needmore formation of WV, Devonian. 10mm x 8mm. I even consulted the chart that @piranha was kind enough to provide me with last time but I’m clearly still developing an eye for hypostome detail. Pictured are both the internal and external molds. Ignore the partial goniatite above it (or enjoy its lovely suture lines, who am I to tell you what to do?) As always thanks for your time!
  23. 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 :

    Likely Triarthrus, possible eatoni

    I was examining a rock with some crinoids and bryozoans I found in my garage a couple months back, and I was able to find this very small trilobite. It looks to me from my research to be a Triarthrus, but I'm still a little unsure on the species. I'm leaning towards eatoni, though I'm not 100% sure. Apologies that the photos aren't the best, but the thing is really small and I don't have the best macro camera. One more note is that I'm aware Triarthrus eatoni isn't found in my area, but I don't know exactly where this rock came from. If I can find the species hopefully I'll be able to get that

    Cambrian trilobites and creatures

    Hi, i've just used my first binocular yesterday and decided to take a look on the pieces of schist i had collected in La Maurerie, member of the Coulouma formation, Cambrian, Montagne Noire, France. I need help to find out what i saw on them. Firstly, i splitted a piece of schist in two yesterday and found those tiny rounded things that puzzle me a lot. The whole of them form a shape of a little less than a centimeter. I also found that partial cephalon of one centimeter (part and counterpart) and wondered if it was from a Solenopleuridae or Trinucleidae.
