  1. Trilobite from kinnekulle

    Found this pretty big pygdium of a trilo in kinnekulle. What species is it? Its around 6-7 cm and if u can see it as a long crack running down the middle. ( found it like that ) should i use some cyanoacrylate to fix the cracks and them remove the leftovers with some acetone? How careful do i then need to be?
  2. Hey guys, Saw this very nice looking trilobite for sale at a reasonable price, so I’m thinking of buying it. However I’m curious to know whether or not the specimen may be fake/retouched/in any way artificially handled. What do you guys think? Thanks in advance! Max Declivolithus Trilobite Ordovician Period Alnif, Morocco
  3. A cute little kettneraspis

    I have not posted anything for quite a while as I have been very busy doing prep for a number of dealers and a major Museum. Unfortunately without their permission I cannot post what are some spectacular pieces. I figured I deserved to do a piece for myself for a change. Started this one on the Sep. 19th and finished this afternoon. I did not really track the time but probably in the 6 to 8 hour range. Unfortunately the fellow that split the rock in Morocco was not the gentlest on the bug. The matrix was in three pieces before I glued it back together. There is no restoration or coating on this Kettneraspis (Leonaspis)at this point in time... Might do a tiny bit of restoration on the join line but have not made that decision yet. Let me know if you would do any restoration on this one. The preparation was with a COMCO MB1000 at about 20PSI using 40 micron dolomite mostly with .018 .015 and .010 nozzles. The scribes used on this one were HW-10, Pferd MST-31, CP 9361, and HW322. All preparation was done under an Olympus SZ3060 Zoom scope. As many of you know I never prep anything without a scope. The matrix was put back together with super thin cyano acrylate and was clamped for 24 hours before starting prep The bug is 24.3mm long 24.07mm wide The first two pics are as it is sitting right now (potentially completed) and the ones before are taken during the prep. The difference in matrix color is due to indoor versus outdoor pics The reddish matrix pics were taken outside. Not the greatest pics just with my phone.
  4. Found this trilobite a while ago. But i have no idea how to prep it. The matrix is super thin some parts i can prep. I will probably damage the fossil if i try to prep the thin parts. Any tips?
  5. Seed or something else?

    Hi, was on a road trip a few weeks ago for work and stopped at a spot where rocks had been excavated along the road. These rocks where full of partial leaf imprints and stems, alongside Trilobites and bivalves. The first pic is of a few partials I found, second pic has the fossil in question and a stem or leaf of sorts. I am not sure of the age as I'm still trying to piece together how there are leaves with the devonian fossilsI'm guessing that the the rocks are from different layers, the fauna bieng middle to late devonian while the Flora is permian in age. Anyway, will not be getting a chance to go out there anytime soon again. What do you think the spherical fossil could be? Thanks
  6. Hi everyone! Today I went on another fossil hunting trip with the fossil club the BVP. https://www.paleontica.org/sites/fossil_site.php?plaats=3&language=en We visited the "La Couvinoise" quarry in Couvin, Belgium. The rocks in this quarry are part of the Hanonet Formation which lies at the boundry of the Eifelian & Givetian. But the layers we searched in today where all Givetian in age (387,7 - 382,7 mya), I mainly searched in the Crinoïd & Brachiopod layer. Although I have to admit that we probably visited the quarry at a bad moment, as the yield was quite poor in the quarry this time according to members who've been there before. Which was quite obvious as I think we only found our first fossil rich rocks after 50 minutes of searching and even then the first hour of finds where few and poor in quality. But after a while of searching I found some good and rich blocks and managed to get some decent Crinoïd stems, Brachiopods and some rugose coral pieces. But the best 3 finds we did during the last 30 minutes of being in the quarry. The 1st one was the only Trilobite I found during the hunt! Trilos are very rare from this quarry and I believe only 1 other member found one before me on this trip. I found a pygidium which is still partially enbedded in rock. At first I wasn't sure whether I was a trilo or a brachiopod but after having a couple of other members checking it out, they all believed it to be trilobite. The excursion leader time was quite amazed by the find as this trilo came from the Crinoïd layer, which is a layer where he believed no trilobite had ever been found. The trilobites are usually found in another part and layer a bit further in the quarry. So yeah I am very pleased with that find! The 2nd best find, was one I didn't find myself but recieved from our Excursion leader Tom, which was a piece of very nice Stromatoporoidea which I wasn't lucky enough to find. The 3rd best find an perhaps my favorite was something that Tom told me to check out. He had discovered the remains of a cave that collapsed during some excavations in the quarry. You could clearly see the remains of dripping stones on the walls and luckily for us, some pieces of those dripping stones where also laying on the ground. So I managed to take a nice piece of them home with me They are encrusted with a layer of dried mud but I am sure they will look gorgeous once they are cleaned! The rings are already clearly visable in some areas. Here are some pictures from inside the quarry. This was the way to the newly excavated plateau which unfortunatly was a complete was of time as not a single fossil could be found in those rocks. After that we went to the other lower parts of the quarry where I mainly worked in a single piece of wall in the Crinoïd layer. I was lucky enough to find a few good fallen blocks and some good places in the wall with some decent Crinoïds and Brachiopods. One of the nice Crinoïds stems I found in the layer. And here is the piece of wall that has some of the dripping stones in it.
  7. Trilobite Contest

    A few weeks ago, I had the pleasure of hunting with @GeschWhat and her daughter. We examined the Eau Claire Formation of the Cambrian in western Wisconsin. Lori had little interest in the trilobites that frequent this formation. She kept busy examining the matrix for trace fossils and other goodies it may reveal. She left the trilobites for her daughter. A large slab had broken free from the cliff during the winter and Lori discovered an interesting pattern on the surface. We worked on extracting a substantial chunk for her and in the process found a deeper layer of trilo-bits. I am a hash plate fanatic. So after she was done with the slab, I extracted a large sample containing the trilobites. Here is a corner of the hash plate: So the contest is a mindless one!!!!!! My kind of event. The person that guesses the number of trilobite cephalons and pygidiums on the hash plate is the winner!! The count was made using identifiable bits. Three counts were made and then averaged. One guess a day until a winner is found. At that point, I will share the hash plate with you and mail a smaller version to the winner. (Unfortunately postage out of the US can be spendy, so I will pay $20.00 if those overseas would like to participate). Good Luck! Mike
  8. Thinking of purchasing this trilobite any info on it would be great says it’s from Oklahoma What genus/species is it?
  9. USA trilobite ID (Eldredgeops?)

    Hello from Moscow, Russia I bought this trilobite years ago on that auction site. I dont have clear info about it. Probably Eldredgeops rana from Sylvania?
  10. I found these 2 specimens (molds unprepped) of the trilobite Calymene celebra, the official Wisconsin state fossil, in the Silurian of Wisconsin.
  11. Phevo's prep thread

    A year and some ago I bought a Krantz W 224 airscribe to start doing some mechanical preparation and promised to do a prep thread once I got started. Prior to this type of prep I have done a lot of silicone casting (which I might make a separate thread for) and on softer matrix used a mix of dental picks/tooth brushes. I have had several different setups over the past year, and the past 2 months or so can be seen on the following picture After spending a tedious amount of time with the rough matrix removal I decided to add a Cp9361 airscribe, which has sped things up a lot.

  15. Trilo??

    This was found in the Ordovician Platteville Formation near Platteville, Wisconsin. Only a tip was exposed and i thought it might be a trilobite but prepping it further, it looks like just a fragment. My best guess is that its part of the cephalon but its curved and I can't really tell which part it might be from. Any opinions?
  16. Hi everyone this is matt again today in the creek I found a trilobite and a brachiopod in one rock here is a photo
  17. Preparation tips?

    I was able to find this guy over the weekend and am really interested in prepping him. From what I have read air scribes tend to be the best but from initially looking they are a bit more than I would like to spend, especially this new into the process. I was wondering if anyone thinks a Dremel or something would work decently? I have some other things like brachiopods that I can practice on and I plan on using a dental pick or needle once I get super close to the fossil. Does anyone have experience with using Dremmels to get down close to the fossils?
  18. Central New York

    I’ve been out hunting three times since my first trip a few weeks ago. Today my whole family spent a few hours at DSR. It took a long time, but I finally found my first complete trilobite!
  19. Wayne County Trilobite?

    A couple years ago I was on vacation in Wayne county Ohio, and I stepped on something in a lake I picked it up and found this. Originally, I thought it was a shell piece, but when I looked again it looked like a trilobite because of the three lines. I know it’s partial so I’m unsure if I’ll get an ID but I hope I do. Ignore the scratch marks, I tried uncovering more but the rock is very hard and impossible to clear with a small tool.
  20. Location is hällekis kinnekulle
  21. Hi, I’m new to collecting and have just purchased these. Do they look real? It’s hard to tell but I’ve checked the usual as per other suggestions, but I’m not sure. thanks
  22. Central PA Tips?

    I'm currently planning out some sites to check out in the Central PA area... I'm trying to stay within 1-1.5 hours of Harrisburg if possible. Right now I am considering trying my luck at exploring the Rockville Quarry or what was left of it, as well as just taking a shot in the dark and checking out a few streams in the area. My first official fossil hunt was last Friday (Aug 28) at the Swatara fossil pit. Found a few shells and what I believe to be a partial trilobite exoskeleton or imprint. Definitely going to check that site out again though. Does anyone have any tips/locations for the Central PA area? Right now my holy grail is a complete trilobite but I'm so new to the game that I get excited at any remnant of a previous life.
  23. I went up to the UP this week doing mostly sightseeing with my friends. They were aware of my predilection for rockhounding so we often made stops to areas that might bear good fossils/agates. In particular I knew there were some 'lagerstatten' in the Stonington Peninsula region of the UP. The most important formation I know of is the 'Big Hill formation' (correct me if I'm wrong). Some links about it here: https://www.researchgate.net/publication/308005515_A_new_Lagerstatte_from_the_Late_Ordovician_Big_Hill_Formation_Upper_Peninsula_Michigan https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6325806/ Now, I didn't have enough time to bother my friends into finding these exposures (and as far as I know, rock collecting in a national forest is not allowed)... However, while we were driving south on County Road 513 T on the west side of the Stonington Peninsula, headed for the lighthouse, I spied a small hillcut on the east side of the road. The hillcut was directly across from a large cemetery-- we pulled over and I had a quick look at some of the rocks there. The hillcut itself was about 20 feet tall, and maybe 600 feet long. I could see near the top of the cut a few feet of limestone bedding planes jutting out from the escarpment. Weathering had amassed a slopped pile of clay and fossils that nearly filled the ditch at the base of the hillcut. On the surface, I saw many brachiopods (different kinds of Platystrophia, possibly?) some of whom were larger than 2 inches across. I also found some small bryozoan colonies and possibly pieces of isotelus gigas molts. The pieces were too small to tell, I am unsure if this particular roadcut could yield anything fully articulated. The rock was very weak and almost clay like. Does anyone know about this roadcut? What formations might be there? I took a few small samples with me but I didn't want to start excavating, obviously. If anyone is interested I could post some pictures of what I picked up, or I could send more detailed directions. Best, Foss
  24. Hello Fossil Forum members! I am planning to drive over to Wardensville, WV, to go fossil hunting! I have previously hunted for shark teeth and bones at Calvert Cliffs, but I have always wanted to find a trilobite since I was a kid, and I am wondering if anyone has any advice for finding trilobites in the area. So far I am planning on bringing a hammer, chisel, gloves, newspaper, and plenty of water. I am planning on going to the roadcut location listed on fossil guy.com. I am wondering if anyone has suggestions such as which parts of the cliff to dig, how to recognize a trilobite, or even better, any good spots to find a trilobite! I am not looking to collect many fossils, I am more interested in finding a single trilobite, partial or whole. I am moving more than 10,000 miles away in 2 weeks, will not be able to bring lots of rocks with me in my suitcase. Any advice would be greatly appreciated!! Regards, James
  25. Receiving an unprep Acanthopyge sp, the tail does not look like the typical Acanthopyge tail from just doing a quick image search. Definitely looks lichid but I'm wondering does this piece match any of the described species of Acanthopyge? Thats if it is one in the first place of course. Below is some information. AGE Middle Devonian (~393 Million Years) LOCATION Jbel Issomour, South Morocco FORMATION Jbel Issomour Middle Devonian Outcrops Would like to get this specimen preped one day as due to a medical condition I cannot prep and reveal anything further myself.
