  1. Help to ID Trilobites fron Wheeler Formation

    Hello friends, I need your help to learn a little more, I am not an expert in trilobites, in fact what I own are the Brachiopods, but accommodating my fossils, I found myself very similar and they filled me with doubts, can you could help me distinguish between an interstricted Peronopsis and a Ptychagnostus atavis, both of the Upper Cambrian, of the Wheeler Formation, in House Range, Millard county, Utah. Thank you.

  3. Penn Dixie 2019 Dig With the Experts

    Tickets are almost sold out! Don't miss your chance! Join us for our signature event — Dig with the Experts! This is our very popular, once yearly opportunity to unearth the best, most complete, and most unexpected fossils at Penn Dixie. We’ll have equipment do the heavy lifting and scientific experts on site to help with locating and identifying the best fossils. You’ll have to do your share of splitting and digging, of course, but you’re guaranteed to find something cool and interesting. Saturday, May 18: 9 am to 4 pm Sunday, May 19: 9 am to 4 pm Monday, May 20: 9 am to 4 pm (limited staffing) Expert volunteers — including scientists, leading fossil collectors, and experts on local geology — will lead the dig in a freshly excavated section of the Lower Windom Shale and will demonstrate how to find Devonian Period trilobites, cephalopods, fish remains, brachiopods, corals, wood, and a range of other marine invertebrates. Thanks to our experts, we are celebrating our 15th dig in 2019! Saturday participants will receive a special commemorative gift. But, wait — there’s more! ‘Paleo’ Joe Kchodl will once again join us for a special science talk the evening before the dig. Paleo Joe will present The Fossil Adventures of PaleoJoe at on Friday, May 17 at 6:30 pm in the Gateway Building Auditorium, 3556 Lakeshore Road in Blasdell, NY. This family-friendly presentation is FREE for Penn Dixie members AND registered dig guests, or $5 for the public. No reservations needed. Tickets: Saturday, May 18: Members $35, non-members $40 Sunday, May 19: Members $20, non-members $25, under 18 $15 Weekend Pass: Members $45, non-members $55 – SAVE $10 Monday, May 20: Included for all guests. Director’s Notes: This program will sell out — please reserve early. In commemoration of our 15th dig, we offer Child (under age 18) tickets for Sunday’s dig at $15 each. Children are welcome to attend on Saturday at the regular rate. We do not recommend that children under age 7 attend this program due to the technical and safety requirements. During Dig With The Experts, other areas of Penn Dixie will be open to fossil collectors of all ages and regular tours will be available. Children must be accompanied at all times. Tickets are electronic and will not be mailed. International Guests: Please email Dr. Phil Stokes at phil@penndixie.org with your name, order info (i.e., dates, numbers, and types of tickets), and membership status. We’ll send you a PayPal invoice directly. Dig with the Experts draws collectors from around the globe for this unique opportunity, which was developed and is currently co-led by our friends from the Cincinnati Dry Dredgers. Bring a hammer, chisel, safety glasses, newspaper, and paper towels to wrap your fossils. Extra water is recommended, plus bring rain gear just in case the weather doesn’t cooperate. Food trucks will be on site Saturday and Sunday to serve lunch. Guests are welcome to bring their own food and beverages, as well as a small cart to transport personal items and specimens. Chairs and umbrellas are okay, too. We thank Zoladz Construction Co., Inc. for their help to get Penn Dixie ready for this big event. https://penndixie.org/dig-with-the-experts/
  4. My first 3D trilobite

    An unidentified species of Paralejurus, dated to the Emsian age of the Devonian. It's from Jebel Oufatene, Morocco. It's also my first 3D trilobite. Of course, I bought it, I don't have any skills in finding fossils and preparing them. They'll hopefully develop in the future though.
  5. Fossil IDs (if possible)

    I like collecting fossils, but I usually am not sure what my finds are. Please, could you help me identify these fossils? I noted down some possibilities down below. 1 - could be a late Albian ammonite from central Serbia, but I am not entirely sure. Acquired in Serbia. 2 - Found at Southerndown, Wales. Could it be a tree root or something in the region of that? It has a cross-hatched pattern if you look closely. 3 & 4 - A shell I found at Penarth, Wales but I am not entirely sure what it is called. 5 - A bone I found in the mud at Tites Point, Severn, Gloucestershire. maybe a birds? 6 - Some shells I found in mudstone at Charmouth, England. Was found in the same stone as 7. 7 - wood I found at Charmouth? It was very crumbly and delicate. 8 - A Trilobite fragment possibly, Llanfawr quarries, Wales. 9 - A bivalve I found in Southerndown. Not sure what it is though.

  7. Hello all! It's almost spring, and that means it's time for @Kane and me to alter the geography of New York state once again! Current plans are to start at Penn Dixie on April 26th, then off to the DSR area on Saturday. Sunday is a mystery still, but we're working on it. As always, anyone is welcome to come out and join in the destruction, er... fossil hunting. Last year was a heck of a thing, lots of good stuff was found, and I think everyone had a pretty good time. @Pagurus, @JamesAndTheFossilPeach , @Fossildude19 , @Malcolmt, @Jeffrey P (I'm sure there are more I'm forgetting off-hand.)
  8. Devonian of NY

    Been taking some pictures of fossil finds the last couple weeks and decided to share. These are from our last couple trips.
  9. This spring break (March 17th-23rd) my girlfriend and I are planning a trip in Utah, Wyoming, and Colorado. It looks like most of the big dig sites are closed for the season, which was a disappointment for us to see. The tentative plan was to go through Kemmerer from Salt Lake (home,) and hit the digs sites there, go through Vernal to the Quarry and the Prehistoric Museum there, then to Dinosaur National Monument in Colorado with a possibility of hitting Price Utah and the Cleveland Lloyd Quarry on the way back. Without any of the digs open, it seems like we're just trying to find simple things to kill our time, but we'd rather be out doing more engaging fossil hunting or learning. Does anyone have recommendations for areas somewhere nearby where our travels will take us? Any suggestions for digs, museums, cool fossil shops, or even just pretty places to camp are all welcome and greatly appreciated!
  10. Hey everyone! You were all so great when it came to helping me determine what fossils were authentic and worth spending well on. Well, I recently came across an online seller. I purchased a "jaw bone" (authentic teeth, the typical fake jaw set in sand) and noticed they are now selling many more fossils that appear to be complete casts. Is it worth reporting them or could it be that they don't know much about fossils themselves and are being conned by their suppliers? They have 100% positive feedback so I guess their customers don't know what to look for either?
  11. I have been asked by a couple of TFF members if we have personal collecting interests in addition to what we collect for educational purposes. We keep most of our posts about the education side of what we do because 95% of what we collect is for education. We also have legal bits that guide how our own fossils are used in the education program which I covered in a previous piece. To summarize that post, there is a distinct line drawn between fossil that belong to Fossils and Wheels and how they are used. My son and I loan our personal collection for education programs plus we have donated a good portion of our fossils to be given away to students. My son and I do have own collecting interests though but we have not really picked up anything for ourselves lately. Carter loves Trilobites and he does have a couple of inexpensive fossils. Part of his high school graduation present is going to be a couple of nice Trilobites and I am starting to learn more about collecting Trilobites. I do collect whale fossils from STH and all of them are part of the education program. The first fossils I ever found were STH cetacean fossils. I still have the two teeth and the vertebra that I found. I do plan on acquiring more whale material and donating it for scientific research. I want to contribute to the scientific knowledge of whale evolution. I do also collect Carboniferous era shark teeth. These also get used in the education programs but I will occasionally pick up items that are not for the education program. We posted a number of our teeth from this era but there a few we have not posted because they are not for the ed program. This includes a Glikmanius tooth that I am quite fond of. I do also have a cladodont tooth that is likely from an undescribed species and that too will eventually be donated. We are very new to collecting dinosaurs but there are some dinosaurs that I plan on adding to my personal collection. I am totally fascinated by the Dromaeosaurid dinos. I studied birds of prey in the wild and worked with injured birds of prey for a decade so it is not a real surprise to me that raptors are my favorite dinosaur. They may not be related but they fill similar ecological niches and I have seen hawks hunt on the ground numerous times. A hawk running after a rabbit on the ground certainly looks exactly like I picture the "raptor" dinosaurs hunting. The biology and related ecology of the Dromaeosaurids is just something I really love the learning about too as it was with birds of prey. Our collection, as of right now, it is not super impressive. We have a Judith River Saurornitholestes tooth and a Hell Creek Acheroraptor tooth. They are two of my favorite fossils though. We will talk a lot about raptors in our presentations and that is a reflection of my interest. All of my purchases right now are for the benefit of our education program but I would like to make a personal purchase in the near future. I want to add another species of Dromaeousaurid to my collection and not because it benefits our education stuff. It would be just for me really. It can wait as we have our collecting priorities but eventually I will get just a tad selfish and find a nice piece to add I am leaning toward to probably putting a post on the member to member sales forum here regarding this interest before I go to a dealer. I have really enjoyed my transactions here so far. Anyway, that is the story of our personal collecting interests and hopefully it is helpful and/or slightly interesting lol Here is the Acheroraptor tooth.
  12. Trilobites Vireux France

    Hello, I recently accuired these French trilobites from an old collection. They are ID’ed as Phacops latifrons from the lower devonian of Vireux France. Doing some research I suspect that they aren’t called that way anymore. Can someone assist me with the correct name? Thanks!
  13. 2/23/2018

    I posted this under member introductions on accident but today me and Devoniandigger got to dig for the first time this year. I had an ok day pulling out 9 rollers and a prone eldredgeops and Devoniandigger walked out with countless rollers, a double with a prone and a roller, and a triple with 2 prones and a roller. All in all great day at the site.
  14. Hey everyone, Several weeks back I posted about a James Hall book I bought on amazon. I also expressed my interest in the original publication “Eurypterids of New York Sate”. @GerryK messaged me and told me he would sell me a set. We got talking and he invited me to Rochester to check out his collection, talk fossils, and pick up the book in person!! This was before Christmas and we both had to wait out the holidays for our meet up. Well I finally went and visited Gerry on Sunday. What a great time! Gerry is a trilobite wizard.....no doubt about it. We started at his house and started going through some of his very very extensive collection biggest hypospme I’ve ever seen! Some Wanakah Shale rarities Awesome kettnerapsis..forgot where Gerry saidnit was from but it was something special.
  15. Hello everyone, When I joined the forum I shared a few of my Buffalo, New York trilobites but only my rare Pseudodechenella rowi trilobites. I said I was eventually share some other trilobites so here I am haha. The winter has kinda been a bummer recently in upstate New York but we just had a freak warm day recently. In the future I want to share my Eldredgeops collection, brachs, cephalopods, plant specimens but I’m not going to rush it. In this post I’m going to share some of my Greenops sp. that I have collected exclusively from the wanakah shale on the Lake Erie shore south of Buffalo, New York. I think I may have an example of Greenops barberi and Greenops grabaui in my collection but I guess I’m not 100% confident in the ID. These 4 are probably my best specimens I’ve managed. For reasons most likely related to environment they are not common and they do not like to preserve well. I would consider them pretty rare actually. Ill follow up with a few more photos of some “lower shelf” specimens I’ve found lol.
  16. Five years ago today, we lost a beloved friend of the Fossil Forum, Caleb Scheer. It was a sad day when his father, Al, "Roadcut1", informed the Forum that he died. Caleb was very knowledgeable in the Ordovician trilobites of the Midwest. He took this knowledge to create the website "Midwest Paleo" that illustrates some exquisite trilobites from the Ordovician in the Midwest. On the Forum he would make over a thousand posts, making comments, helping identify fossils and posting pictures of the fossils he collected, especially trilobites. His avatar is a beautiful coiled Cybeloides iowensis he collected from the Maquoketa formation. Last year after MAPS, I visited Al to do some field work collecting Ordovician trilobites. While there, we visited the cemetery where Caleb is. On his head stone, the family had the image of a Ceraurus trilobite put on it. An appropriate way to remember his love of trilobites. I am currently working with two others on the revision of Ceraurus. We will be honoring Caleb by describing and naming a new species of Ceraurus after him that he collected from the Mifflin Member of the Platteville Formation.
  17. Hi all, Rather late than never, i managed some time to make a photo galery of my best find of 2018. I mostly hunted trilos, but also manages a few trips for ammonites, echinoids and even graptolithes. The time span is quite wide also : ordovician, silurian, jurassic and cretaceous. I wont post everything (it's been a productive year again) here but you can see it in the galery : or on my flickr galery here : https://flic.kr/s/aHsm9dKo7r Regards
  18. Hello all- I am in the early stages of planning a fossiling outing to TX and OK in March. Would any of you folks be willing to either point me or take me to sites out there? There are a lot of different fossil in these states and I have been in touch with a few forum members already, but I would appreciate any help any one can offer. I have Waurika and the Wilson Clay Pit o the list already. I imagine I can do NSR solo, but anyone who would be willing to show me around there would be a hero. I don't plan to go as far as Houston but Austin maybe for Whiskey Bridge.... A crab would be a real prize... or a TX trilobite. Many Thanks. Answer here or PM me.
  19. Devonian trilobites of Gondwana studied with newer mathematical models to determine evolutionary connections https://phys.org/news/2019-01-reconstruction-trilobite-ancestral-range-southern.amp
  20. Hey everyone, As some may already know I’m in Austin Texas until Sunday. Leading up to the trip I couldn’t pinpoint any reliable Texas locations due to water level reports and people warning about water levels at some localities. Some of the places I was interested in were on rivers. I could have wasted a lot of time if I showed up with high water levels. I’m only here once to I needed to chose something with less of a gamble. So I figured I would just scratch my trilobite itch up in Oklahoma!! We arrived in Austin on Tuesday and I had arranged a hunt with Leon for Wednesday. This way I would be back to Austin Wednesday night. Turns out Leon and Alan Lang are best friends of over 30 years! Leon actually called Alan to ask who I was and I passed the test haha. Small tangent but needs to be said......Leon, like Alan Lang interview people before letting them in. Sadly the intentions of some people are not pure. Also some people gripe and groan about prices as if complaining will be enough to get a discount. Or people get too pushy and try to dicker price making the whole thing awkward...It doesn’t work like that. Yes Leon’s and Lang’s are pay to dig. Yes we all want free fossils and for the most part free fossils are available all over the country/world. They are nice to even let us in. People don’t really appreciate or I should really say “understand” the investment it takes to own these places. They don’t have to let us in at all. Think of Caleb’s quarry (Rochester shale) and the quarry exposing the Trenton group with exquisite trilobites. Good luck even getting access to those places. I hear the owners of Caleb’s quarry are very nice people but it’s private. Privately owned and privately dug. There are places like this all over the world....privately owned and privately dug. I’ve seen a lot of stuff on the forum kinda knocking the pay to dig quarries and I think it’s a matter of perspective and possibly jealousy...heck I’m legit extremely jealous!!! If I told you how much money these guys poured into these places (especially Lang x10) you would ask...”why aren’t they charging more!” After one conversation in person you would probably change your tone and realize these guys are just like us....fossil crazy and actually quite nice. Ok back on topic I met Leon in Coleman, Oaklahoma at 8am yesterday (Wednesday) and I immediately recognized him. He’s actually on Alan Lang’s website prepping a multi plate. I didn’t realize it was him from the website! We chatted for a moment and off we went! You can’t stumble on this place...and Leon has many stories from 20-30 years ago about people sneaking in and selling fossils before the land was sold to Leon. One story about a particular poacher brought some laughs. Leon’s a funny dude. After the gate we had to literally drive through cow pastures. We saw deer, coyotes (yea coyotes!), cows and a bull! Just driving through the fields ha. The black one further away is a bull.
  21. Cole Hill 1-8-18

    I decided to try my luck at Cole Hill today after seeing @Calico Jack and @Al Tahan's recent luck. With last night's rain, the roads were a bit slick on the ride out, but not terrible. I arrived around 10 and quickly saw where they had been working. They both said they had only been there for a short time but there sure was fresh rock thrown everywhere. Somebody is fibbing! I decided to work a spot close to where I found my last couple, mostly complete Dipleuras. I wish I had something exciting to report but all I found was a lot of the usual suspects. Cephalons, pygidiums, Bembexia, various brachs, bivalves, and nautiloids. None of them were in great condition, but that being said I still had a good time. The weather was pretty nice and I stayed till 1:30. It was nice getting out of the house. Before I left, I heard a car pull in to the side of the road. A lady got out and told me that I needed to get permission to hunt there as her family owned the property. I asked her if she was the daughter of the lady who lives down the road and she said yes. So I explained that I had gotten permission from her Mother back in 2003 and have been coming there ever since. She said her mom didn't recognize the car. She was very polite about everything and I talked to her for a bit and also explained that I have talked with the mother from time to time and some other family members who hunt the property in the fall. Then she went on her way. I stayed just a little while longer as my back was starting to hurt. Better luck with the trilos next time.
  22. What are these?

    I was just wondering what the species for the trilobites are but I’m not sure what the 3rd thing is as it looks like an ammonoid or nautiloids from most angles but it doesn’t have an aphycyus it has an operculum so is it a devils tonail thanks
  23. Trilobite from Udig, Utah

    Hi everyone. I'm new to preparing and don't have the money to get the proper equipment. However, I do have the Harbor freight Air eraser I was recommended by several b people on here. Anyway, I have one of those tiny to segment Trilobite who name I forget for the minute. The matrix he was in broke up, so I've mounted it to another piece of same udig shale before I start work on the Trilobite so I don't have it break n in half. There's a small Gap in the matrix because it's not a perfect fit, but Very close. The glue is holding well and clear , but what can I use as filler for the tiny Gap? Can I mix clear glue with some sanded matrix mixed in to make a filler? Thanks everyone
