  1. Up for trade, Two Flexicalymene retrorsa found yesterday in St Leon Indiana. Ordovician.
  2. Trilobite Ceraurus Foulornia sp. ?

    @piranha @Kane Looking at this piece and want to make sure its real. Also I can't find anything online that confirms the listed Ceraurus Foulornia sp. Matrix measures 8 x 6 .5 inches. Trilobites measure 2 to 2.5 or more in length depending if you include spines. Width is close to that. Ordovician Morocco. I can get it for around $100 but don't want to spend the money if its fake and without confirming the species so I can find some reference prices. Thanks for any help with the ID and authenticity.
  3. Milwaukee

    What spots in Milwaukee would be good for hunting fossils? I'm taking 2 older boys with me as my lil son and wife will have to stay at hospital overnight.... any spots? My oldest son is interested in try to find trilobites.... thank you.

  5. Trilobite Fossils Identification

    Greetings. I have a few trilobite fossils that I do not know the scientific names or proper identification for. I could google image search but that might take forever :). If anyone can help with any of them, i'd appreciate it. Thanks!
  6. Hello everyone, I was patrolling my odd Devonian location that has rocks I'm guessing from Upstate New York that are littered with Devonian fossils and came across this on one of the large rocks (unfortunately I can't extract). I'm unsure if its maybe a seas scorpion, trilobite, or something else. My guess leaning towards sea scorpion of sorts but I'd like to hear what you guys think, its the only of it I've seen in the area wish there was more or the rock it was on wasn't a unliftable boulder haha.
  7. Here are a handful of trilobite fragments Mifflin Group, Platteville formation of Ordovician. Most are very tiny, my son and I pick them out with a loupe then I photograph them @ 1X1. Here is my son, Alan on a search. He is almost 11 years old, his eyes are getting to be noticeably better than mine (43). So for the trilos, I'll start with a couple pygidia. Pic # 1 Pic # 2 This is a real question, I don't even know what it is. The texture looks trilobitish, at the very least is definitely not consistent with bryozoan or mollusc, so ? Pic #3 Here is an individual thoracic segment. Pic # 4 Thanx for any help. I have thoughts on these, but would really appreciate any more input. Matt/Al
  8. U-Dig Part 2

    Since my move to Utah two weeks ago I have been dying to return to U-Dig. My wife allowed me to go on one condition, that I would be back home by 3:30 in time for her brothers farewell party as he is going on his Mormon mission next Wednesday. I ended up calling Shayne the quarry owner, explaining my dilemma and asked him if I could start digging at 7:00 am, two hours before the site opened. Surprisingly he approved and I called Bevan. Bevan was going to man the station at U-Dig so Shayne wanted me to give him a heads up. I awoke on Saturday morning at 3:30 am and hit the road at 3:45. I was at the site by 6:45 and digging by 7:00 am just in time to see the sun come up over the hills and the sun rays radiate off of the storm clouds from an early morning storm. Had a phenomenal trip. Dug up fifteen Asaphiscus wheeleri, eight Elrathia kingii, and one Perenopsis. If you ever get the chance to dig here do it. You will not come away disappointed. I met a gentleman named Nick from Syracuse, New York and we talked about all the neat sites in western New York, primarily Penn Dixie. Bevan volunteered me to show three guys who had never dug the Windom shale on how to find good trilobites. We all walked away with some great finds. Breathtaking view at sunrise. Notice the dispersing rain clouds. An omen for a perfect day. I certainly miss Calvert Cliffs in Maryland along with some other eastern coast marine fossil locations but the view here in Utah is absolutely sublime. The nothingness of the desert has a certain beauty to it. Witnessed two antelope on my way out and one of them was matching the speed of my car at 40-45 MPH these amazing animals can top out at 55 MPH and they need to be that fast because Mountain Lions also referred to as Cougars or Puma top out at 50 MPH. I was certainly on the lookout for scorpion, rattlesnake, and Cougars but didn't see any. Rattlesnake seem to be the most common and dangerous. An assortment of Asaphiscus and Elrathia. Most are molts but some are complete or near complete. The bottom left is complete (2 inch) and bottom right is near complete. Both are Asaphiscus wheeleri and large for their size. This is the find of the day and more uncommon than Elrathia kingii. This is a prone two inch Asaphiscus wheeleri. Bevan noted there is some oxidation but that could be prepped off. Not sure what to do with it. Might need to send this one to a professional *cough* @Malcolmt *cough* though I do owe some of these to my other Canadian friend *cough* @Kane *cough Disarticulated Elrathia kingii. I normally don't see them like this and there are some orange flakes where the top side broke off. I believe this one is a complete specimen and not a molt. Interesting preservation for this specimen. Found this large Elrathia kingii out in the open next to a bunch of rock with hammer marks. Someone must have been splitting rock and this specimen popped out. Not the best Asaphiscus but should make for some good preparation practice. Large Asaphicus wheeleri molt. For most of the day I was targeting these as opposed to the more common Elrathia kingii and found a really good location where a bunch of Asaphiscus where colocated. 1.5 inch Elrathia kingii. Should prep out nicely from a gentle dremmel brush. Another near two inch A. wheeleri. This one appears to be a molt. The disarticulated E. kingii. A collection of E. kingii. Most are molts. One large slab contained about fifteen of these but I didn't want to haul it back to the car. It was a great day. E. kingii. Should be complete. Needs some prep work. Close up of the big one. Large Asaphiscus molt and there appears to be another inverted over to the left. The yellow color on this Asaphiscus is interesting and I believe Bevan said this was oxidation. I'll need to do some more research as to why this happens. This would have been a phenomenal specimen but the glabella is missing. I'll give it to a friend. Disarticulated Asaphiscus molt. Elrathia that should prep nicely. This one is interesting. It appears to be a complete Asaphiscus but is inverted revealing the ventral side. If anyone is up for a prep challenge let me know and I'll send this to you.The color is a dark brown and should make for a very nice specimen. Love the brown color on this Asaphiscus. They usually don't come in this color and the brown is a result of oxidation. Another E. kingii in need of some prep love. Sometimes you'll find what I call ghosts where the specimen is preserved under a thin layer of shale. These generally prep out well albeit this one is a partial molt. Saving it for some prep practice. Some more molts. Partial Asaphiscus that will make for some good prep practice.
  9. Trilobite cephalon, Eldredgeops ? or ?

    Hi folks. Unlucky break, I hate it when that happens ! This chunk broke out in a bad way. I'm pretty sure it is a portion of a trilobite cephalon but it doesn't look like the other eldredgeops that I've found here. Not certain which is fwd or rwd, but the taper of the "center section" appears to be in the wrong direction compared to my other specimens. Perhaps it is squashed/deformed a bit ? Something just doesn't look right about it to me. Any clarification would be appreciated. Thanks.
  10. Hello. Can this be an Ectillaenus? If yes, wich species?
  11. Well I have saved up some spending money and have about $450 I can spend on preparation tools. I have so many trilobites in Shale from Penn Dixie and U-Dig that could be prepared and look really good. Found a compressor with scribe kit that deals PSI at 15-45. I found a cheaper combo that provides 0-35 PSI. So that could cost around $150 including the media. Then a blast cabinet will cost around $150. I'll need to filter that air out and I could probably use a shop vac and rig it up to the blast cabinet. A new shop vac will cost about $40. That's about $350. The extra $100 could be used on some lights or an 8820 dremel for matrix extraction. This should be a fun winter time hobby as Utah is known for bad winters. I'll start selling my surplus prepared fossils to purchase better preparation tools. We all have to start somewhere. I know @DevonianDigger has his own custom setup but I'm not brave .enough to use a tattoo machine. @Ptychodus04 mentioned that a micro hammer is useful but those are expensive and @Malcolmt mentioned some very nice tools that I can't afford yet. @Fossildude19 if you have any suggestions let me know as you do your own preparation. Same goes for you @FossilSloth although your setup is over a thousand and beyond my current price range. Eventually I'll work my way up the ladder.
  12. Wren's Nest unusual trilobite

    Hi I made my first visit to Wren's Nest yesterday. I still need to go through my finds but did well including some Dudley bugs (partial) and lots of coral and brachiopods. However this partial trilobite had myself and others stumped. If anyone can help with ID and cleaning up I'd be grateful (I don't have any professional prep kit like air abrader or air pen). Trilobite at bottom right of first pic. Thanks! Sam

    Posibile trilobite fragment found by myself near McCoys ferry, Maryland.
  14. Hi, Im sorry to be back on this topic again but the suspicion is bothering my way to much after spending even more time looking at this piece and comparing it that resembles a very worn, broken up trilobite head from a possibly large one, the location (New York) I found this in I also found other more clearer trilobites but also a few that are 100%trilobite but worn to point that they nearly blend in right with the rock and have minimal features, my guts bothering the hell out of me so I provided a final set of even better photos below from an angle that I haven't posted on the original thread Hoping for someone to lay me to rest once again and tell me its a rock one more time , the texture though barely visible in the photo makes me believe its something, if not trilobite it doesn't share the same consistency as the surrounding rock and shale in certain areas and upon very close examination has very minimal fractions of pieces with a celluloid trilobitey or living thing texture.
  15. Hello, I am actualy working on a 3 D reconstruction of the Trilobite Triarthrus The body and my references as a blueprint :
  16. Hello, I live in one of those unlucky places that has the bare minimum of natural fossil bearing formation to the point there is pretty much none, I've found an odd location that has rocks I'm guessing from Upstate New York that are littered with Devonian fossils. I have very little knowledge of Devonian trilobites after searching this location I've found a few worn trilobites, but then I stumbled upon this worn monster with a head that seems to measure around 3.2 inches from eye to eye (since lucky they are still preserved enough to see the texture. I'm looking for any help if possible to help identifying this, I treasure this though its extremely broken and worn because I found them in a place that shouldn't have fossil material. Anything will be greatly appreciated, thank you and I'll provide some photos below (it maybe tough due to their condition) From personal research I can only compare it to a Trimerus delphinocephalus cause of the massive size but I am no trilobite expert, and I can only dream. Here is the scale compared to some of my hand, broken head shape begins towards the bottom of the picture.
  17. Hey folks, I'm exited ! #30 IS IN ! The first chunk of shale from the new dig at the outcrop mentioned earlier yielded this specimen. It is much, MUCH larger than all the others and looks as if it would have been complete if it hadn't broke out at the edge of the chunk. This shale is very unstable with fractures all over and throughout. It may fall apart at any moment so I photo'd it before doing anything else. I assume it is an Eldredgeops? I think it would be well over 2" long if all of it was there. I never expected to see one this size, how large do they get ? I may try to stabilize it with watered down elmers, or what would you suggest ? Thanks folks, 30 might be my lucky number now. More pics after I "dig in". Kindest regards.

  20. Trilobite part?

    NW Arizona, walking the dog last week, stopped so he could water a tree, I looked down and found this. I thought it was the back half of a trilobite, but I've been wrong about everything else so it's very possible this is actually the head of a flying mud snail that infested the entire continent last year. Any thoughts? Thank you in advance
  21. Trilobite Prep Help

    I found this trilobite in Little Falls, NY. It's about an inch long. I love the color and the fairly good preservation caused by the pyrite. It looks like there is some very thin shale covering parts of it and I want to remove these pieces. The problem is that I don't know how to do this without scratching or ruining the fossil. I only have a small set of dental picks available to use. Any help or recommendations on what tools to get if I need anything would be appreciated.
  22. Trilobite ? and Coral ?

    Hi folks, found a new one this AM. There is a small piece of a cast loosely fitted in the first pic, then removed and flipped for the second. Can you tell what this is ? Its about 1" wide. Thanks. Also, looks like another little trilobite, bit, butt, pygidium ?
  23. Four specimens presented for discussion. I studied several possibilities and, with a huge risk of error on this tricky ones, I present my hypotheses till now. By now just for the genera, of course. 1st and 2nd pics - Kingaspidoides sp. ? 3th and 4th pics - Kingaspidoides sp. ? 5th and 6th pics - Ornamentaspis sp. ? 7th and 8th pics - Latikingaspis sp. ? (a risky call and Geyer, 1990 don't help as all plates with this genus have just partial cranidia). I found just one photo browsing the web to compare (last attachment). Thanks in advance for your opinions. Miguel
  24. HI all, Here is the last piece of the trilobites write up from our "SW Site" (Stevens Way, Ashfork, Az.) featuring the interesting pygidiums of the Zacanthoides Walapai trilobites we found in huge abundance in the Bright Angel shale. Ill post a few nice shots here, and at the end a link to the full (monstrous) write up on our paleo web site. Thanks for looking! The most common fossil found in the green shales at our SH locality are trilobite pygidiums for the Zacanthoides Walapai species. They are joined by assorted cranidiums, thorax and rib segments, and hordes of hyolithids, and a very rare coralomorph. Generally low diversity such as this site suggests has been attributed to a stressed environment, with perhaps low food sources, aggressive wave action, or an influx of fresh water from the nearby deltas. This was a shallow sea outbound from the deposits known as the Tapeats Sandstone which marked shore, delta and beach deposits. Combined with the deeper water Muav Limestone, this trio of formations is known as the Tonto Group. All three can be found outside the Grand Canyon to the south in small limited areas such as here, yielding an opportunity to explore the paleo fauna without hiking miles and thousands of feet into the Grand Canyon. A few images that are special: The full write up can be found here: http://www.schursastrophotography.com/paleo/Fossilfotos-4f.html
