  1. On Sunday, my family and I decided to head out for a fossil excursion to spend out day.@Uncle Siphuncle pointed out a good fossil site for me to find trilobites at a road cut in St. Leon, Indiana. Thanks a ton!! Unfortunately, as it had rained for quite a while that day, we had to wait until well after noon to reassure ourselves that we would not need to fossil hunt in the rain. Luckily, this also meant we got fresh picks before the other collectors! Here is the haul from the day: (I hope to bring back more over the course of the week!) Top to bottom: (1) Random pieces of the trilobite Isotelus (sp.). (2) The largest piece of trilobite that was found that day at the site. Although the piece is large, this is just a tiny, tiny fragment of the real trilobite! It is included at the bottom of image #1. (3) The best find of the day. It is a piece of the rear-half of the trilobite Flexicalymene (sp.). I do not know the specific specie, but the most abundant trilobite found at the site is Flexicalymene meeki, so it is safe to assume that the trilobite is F. meeki. After staring at the trilobite piece for some time, I extrapolate that it is approximately ~2/5ths of the trilobite which it once was. It is indeed very small! (4) Fossilized gastropods: (5) Fragments of orthoceras. These tend to be larger! ( (6) A handful of associated crinoid stem segments. The 2.4 cm one is quite long for a piece found detached from a matrix. I like it! —————————————— Overall, I think that our trip to the site had not met its maximum potential. We thoroughly examined every foot of ground that we covered- but this was only a short strip of land roughly 20 * 60 feet. Time was not available for a longer hunt. I estimate that we covered less than 5% (!) of the total fossiliferous area available to us that day— next time, I hope to find more than just ~1/3rd of a trilobite! -FS
  2. Isotelus "mafritzae"

    From the album Trilobites

    Isotelus "mafritzae" collected and prepared by K. Brett. Found at Bowmanville, ON. Lindsay Fm. Isotelus from this location have not yet been formally described (hence the suspension marks on "mafritzae"). This is known as the I. "mafritzae" type "B", which has no genal spines (Type "A" has slender genal spines present).
  3. New York Trilobites

    I was just curious as to if anyone knows how to get in touch with someone about possibly being able to dig at Walcott as a guest, as it’s a private quarry, or if someone else knows where to find the gold bugs with appendages. I am hoping someone can point me to where there is isotelus or Ceraurus as it’s my favorite Trilos. Any help is appreciated. Even if you know a guy that knows a guy that knows a worker there lol. Thank you, and Happy Thanksgiving!

  5. My story will be a bit(could be too much) long, so I put this report separately from @Kane's report. I'm not sure I can do this or not 'cause this is my first time to write same topic from others'. If I should not do this, I apologize administrator for making bothersome Before I start my story, I convey my profound and huge gratitude to @crinus for taking me quarries(these travels were my very first visiting to not only quarries, but also Ontario's fossil site!) and giving a lot of nice fossils to me what he found, and to @Northern Sharks for giving a nice specimen to me what he found as well from Brechin quarry and organizing Bowmanville journey(I didn't know that until seeing from @Kane's report. I'm not sure that you set the all plans), and to @Malcolmt for giving a complete crinoid to me, which is my first complete crinoid possessing arms and stems, and finally to everyone that I've met on this travel for welcoming me *Plus - My report will be incomplete 'cause I don't know that much about Ontario's geological information and some species' scientific names. So, I'll appreciate greatly if you guys tell me about right information and help me to correct it I revised this post a loooot of times 'cause I realized that it was not report, but a proper diary(Too Much Information.. and still, it's like a diary..) Well.. Now then, I'll begin my long story with some pictures though I couldn't make to take that many pictures of quarries and people. As for the Brechin quarry, I forgot to take my phone and there was no time to take DSLR out from my bag. And as for the Bowmanville quarry, I was so concentrating to find fossils that I forgot to take pictures *Date : Oct.21&22.2017 *Location : Brechin quarry & Bowmanville quarry *Records of formation : Brechin quarry - D -----> Upper Verulam Formation(There was a "cluster" of fauna that I think it's different from below one. Color was bright grey and somewhat yellowish) DD -----> Middle Verulam Formation(Bluish and grey rocks with vurnerable condition) DDD -----> Lower Verulam Formation(Brown and grey rocks) DDDD -----> Upper Bobcaygeon Formation(Alternates between sublithogenic and medium calcarenitic limestone, but also includes some brown lithographic limestone and bluish fine-grained limestone in minor thicknesses)[*] [Buried under the ground] Middle Bobcaygeon Formation(Grey and brown, very fine grained to sublithogenic, sparsely fossiliferous limestone, with some fine-grained limestone in the upper part)[*] [Buried under the ground] Lower Bobcaygeon Formation(Brownish grey, fine- and medium-grained limestone)[*] (Reference - [*] Bobcaygeon formation - Weblex Canada. (n.d.). Retrieved from http://weblex.nrcan.gc.ca/html/001000/GSCC00053001579.html @Northern Sharks informed me! Thank you! ) Bowmanville quarry - D -----> Blue Mountain Formation (I couldn't get there.) DD Upper Lindsay formation DDD Level 2 (?) DDDD Level 3(?) - Lower Lindsay formation (Below as well. The quarry was so biiiiiig!!) - - *Geological Age - Middle Ordovician These all rocks are what I took. Maybe I took a lot of fossils even if it is only a small part of trilobites. I just so excited that I found Ontario's trilobites directly, not through internet store or pictures! Well.. Now I'm worried the weight.. Could I take these whole fossils?... I should have considered about it, not just collect unnecessary things by my instinct. It was not a clever move.. That crinoid(at 11 O'clock-wise) is not what I found these quarries. I found it from Scarbourough bluffers park before. To begin, the beginning of the day(Oct.21) I've met @crinus first at the very early morning of the day(For me. 'cause I'm not the early bird type). Actually, we met from Ebay. I won his two auction and I asked him that would you wait for me until I get to Canada in order to reduce shipping cost. Then, he offered me to go to quarries with him! Anyway, we arrived there around at 8:30 AM and there were 4 or more people had already arrived. I've met @Malcolmt and two other people(Sorry, I can't remember the name. My poor memory..) on near the greenish and bluish pond in the quarry. After handshaking, @crinus and I went to the piles of rocks, which is near the pond. We climbed up the piles of rocks and met @Northern Sharks on there. He found one complete Calyptaulax sp. and dropped it from his hand while we were greeting each other(yet, fortunately, the trilobite was alive with small crack on the pygidium(if my memory is correct)) After the greeting, @crinus and @Northern Sharks went to another place and I remained there, which was that @Northern Sharks found a trilobite, and looked for trilobites with hammering big rocks. I found a horn coral, which is Lambeophyllum profundum Conrad, 1843, the cephalon part of Ceraurus sp. , and a loooot of brachiopods and so on It came from lower Verulam formation. This one is Lambeophyllum profundum Conrad, 1843( @Northern Sharks and @FossilDAWG informed me! Thank you! ) Ceraurus globulobatus? I don't know the exact name of this specimen.. This one maybe came from the middle Verulam formation because of its color. Though I found this from the lower Verulam formation area.
  6. Hello, I've been recently fascinated by large isotelus trilobites. Does anyone on here own one and would like to show and talk about it, I would if I owned one but I don't see that happening anytime soon haha. This is the largest I've seen for sale so far that would've been 8 inches, would be nice to be able to find one but I don't have that luxury.
  7. Ordovician trilobite

    Hi, I found this interesting piece in Ordovician Platteville Illinois. A very tiny trilobite pygidium on top of a partial Isotelus cephalon. My question is what species is the pygidium? I'm guessing Encrinurus, but not sure...any ideas? Also, how can one tell if it is from a juvenile, this tail measures only 1.5mm. Thanks
  8. Bowmanville ON Spring 2017

    Better late than never, here's a report from June 4th. As some of you knew, and now all of you, I'm the trip coordinator for the collecting trips into the St Marys quarry in Bowmanville ON to collect in the ordovician Lindsay/Cobourg formations. There is also some Verulam fm. at the bottom and Whitby fm. at the top of the quarry. We had 20 people show up for the annual spring fossil dig and in keeping with tradition, it was raining. I, and about half the crowd, started on a large pile on level 3. Almost immediately, the first trilobite was found, an enrolled Isotelus. After a quick preliminary look all over the pile, as I made my way back to get my saw to cut out the first roller, I found his older sibling –same orientation but a bit larger. Not a bad start; one hour in and 2 bugs for me. After hearing that not much was being found on level 2 or 4, several of us continued on the same pile and a surprising amount of stuff came out of it that we all missed the first time around. I cut out 3 prone Isotelus for 2 first timers, another ¾ complete one for another rookie and what may be a really nice one for myself, almost entirely buried so fingers crossed. Several others were found and I left a couple that were just a bit too far gone. One collector spent most of his time in the Whitby Shale at the top of the quarry and was rewarded with a nice Pseudogygites trilobite, the only one of this species found. My find of the day however was a beautiful crinoid (Iocrinus subcrassus) sitting on a rock clear as day with about an hour left in our allotted time. How everyone, myself included, missed it up until now was beyond me, but I won’t complain. This makes it 3 straight trips for me bringing home a crinoid, 3 different species as a bonus, after going years without ever seeing a decent one at this site.
  9. My work as a paleoartist

    I would like to introduce myself and my work. I grew up on a small farm in southwestern Ohio loaded with great locations for the collection of ordovician fossils. I earned my BA in geology and taught fro approximately 30 years. I retired from education in 2015 and have been working as a sculptor since. I do some animal and wildlife work, some fantasy sculptures and some paleontology themed pieces. I aways try to have my pieces looking and behaving in a lifelike and believable fashion as well as being technically accurate. My sculptures are created in clay, I then make rubber molds, cast a wax in the mold and then have the wax cast in bronze in a foundry. Sculpting in bronze is more expensive than resin but the material is strong and incredibly durable. I am currently working on another sculpture of a heteromorphic ammonite that I also need help with. Let me first attach sample of my sculptures to show you my work. Thank you.
  10. Last weekend took advantage of beautiful weather after a week of rain to check out the Platteville formation in SW Wisconsin. Here are some of my finds..please let me know if any of these ID's are incorrect.. Sinuites, extremely common . Ordovician sea floor Beloitoceras, measures 1.5" continued....
  11. Isotelus maximus (or I gigas) juv.

    From the album Ordovician Fossils (by Peat Burns)

    Isotelus maxiumus or I. gigas (juv.) (Trilobita) Late Ordovician: Waynesville or Liberty Formation St. Leon, Indiana, USA This is several views of an enrolled juvenile. It is complete except for the missing genal spines, and the exoskeleton is intact. The dark brown areas are pyritization.

  13. Ectenaspis Sp.

    From the album Fayette County Iowa

    This is a find from earlier this summer that I just got out tonight to start work on. I assumed when I collected it that it was an Isotelus Gigas and didn't give it much of an inspection. I did tonight though. Appears to actually be an Ectenaspis Sp. A Good surprise.
  14. A Day in the Shale

    Got out yesterday to some exposures of shale in Southwestern Ohio. Found a couple nice trilobites; Isotelus and Flexicalymene. A couple nice Isotelus pygidium. I got heavy into some pelecypods and a couple nice brachiopods were laying in the stream, one with a nice bryozoan on top.
  15. My ten year old son has a wonderful opportunity to display his local fossil collection at the Burpee Museum in Rockford, Ililnois for their national fossil day. As he is only ten, many of his fossils are maybe a tad less than museum quality. So, for part of his display he will have some of his mifflin ordovician fossils. He has a couple hash plates with assorted trilobite fragments which are cool as heck, but I think it would be nice to display some photos of complete, or almost complete specimens to go along with his fragments. The species whose images I am requesting are: Gabriceraurus Basiliella Thaelops Calyptaulax Isotelus on a side note. He also has partial tully monster fossils from Mazon Creek, so maybe a couple images of well preserved mazon creek animals would be nice to display also. Maybe the common shrimp and tully. Thanx for any help - it's for a great cause. The images would be used for only six hours then discarded if that is what you wish, or if acceptible, he could keep them for any potential future educational display.
  16. Isotelus gigas

    From the album Isotelus gigas

    Isotelus gigas found in the Eden Formation near Frankfort, Kentucky, USA
  17. Isotelus Iowensis

    Just got this Isotelus Iowensis done with prep. From the Elgin member of the Maquoketa formation (upper Ordovician) in Fayette County Iowa. He was about 12cm long. Too bad he had some damage that I am not able to repair but still a good overall representation of the species.
  18. On an annual basis we get one day to collect in a pretty amazing quarry in Bowmanville Ontario. This year 2015 was no exception. My buddy Dave here on the forum had a pretty amazing day. I suspect many of us would kill for even one of the specimens he found that day. I just realized that I have never posted how his fossils turned out. Turns out he is popping by this weekend to pick them up before a mineral and fossil show up in Peterborough Ontario. Fossil Forum member Northern Sharks is a very active member of the club (Kawartha) that is holding the event. Here are Dave's finds for the day as found. They are all isotelus A pretty damaged isotelus .... but a large one A nice Double Another nice double A nice single
  19. First complete Isotelus

    I came down with a cold this week, but after a couple days I decided I would rather be out hunting fossils sick than sitting around the house sick and staring at a computer. So, Tuesday afternoon my wife and I went fossil hunting at a well-known Richmondian road cut in Indiana. The ground was already wet, and it rained heavily while we were there, but we brought raincoats. After a while, the sun came back out, and we found a good array of fossils from the Liberty Formation. There were plenty of horn corals, brachiopods, and gastropods, but we were primarily after trilobites. Between the two of us, we found 6-7 complete, enrolled Flexicalymene retrorsa minuens, as well as what I believe is a Rusophycus ichnofossil. My favorite find of the afternoon was my first complete Isotelus. Large fragments of adult Isotelus are common at this site (and through much of the Cincinnatian series), but the large ones are almost never complete. Isotelus is not only larger than Flexicalymene, but they also roll into a flattened crescent shape instead of a tight sphere like Flexicalymene. I suppose this might explain why they're not preserved whole as often. Anyway, I found two juvenile, enrolled specimens, though the thorax of one is partially broken off. Here are both sitting on top of a rock containing the pygidium of a much larger Isotelus. Here's a close-up of the complete Isotelus. It measures about 17 mm wide across the cephalon. I assume it is Isotelus maximus, but does anyone have thoughts on how to differentiate a smaller specimen from Isotelus gigas?
  20. Bowmanville 2015

    Well once again, what is becoming an annual trip to St. Mary's cement in Bowmanville Ontario Canada was an absolute winner this weekend. This is a world class collecting locality that unfortunately is generally not available for regular collecting. A number of forum members were present but a big hats off thanks to our very own Northern Sharks (Kevin) for leading and organizing the trip this year. This is the only day in the year that the very active quarry with 5 levels is open for collecting. Approximately 30 collectors took advantage of this and made it a very special day. The weather was amazing for late October and not a drop of rain unlike some other years. The quarry was quite muddy as it had rained non stop the previous day but that is a good thing because all the rock piles were nice and clean. I only saw what a few collectors found as Quarryman Dave from the forum here and myself were too busy making then most out of our limited collecting time (9:00 to 4:00PM). We are all here for the trilobites...... I did see complete isotelus, ceraurus (2 species), thaleops and flexicalymenes that were found by people. My saw got a fair bit of use cutting mostly isotelus and a few ceraurus out for people on the 3rd level. I think Dave and I did reasonably well, though we only found isotelus and perhaps a thaleops that were keepers. We did find a lot of partial ceraurus but nothing worth bringing home. Dave found two double isotelus plates and we found a number of complete iso's.... Everything that we found was on level 3 and 4 of the quarry. We did not have time to look at levels 1 and 2 and level 5 seemed a bit too wet and muddy for my liking. From what I heard from a few others nothing of note was found on level 1 or 2 this year. I know Peter Lee spent some of the day up there and he did not find anything but partials from what I recall. Here is the group picture of what we found all unprepped at this point (the trip was only yesterday) We should get a few nice ones out of this batch once I get them prepped. I will try to post some pictures as they get completed but that will not likely be for a while as I have a large backlog of material to prep for myself and others. Other members of the forum that were there please jump in and show us some of what you found. ..........
  21. isotelus plaster cast with base

    From the album My fossil replicas (casts in plaster and resin)

    This is a plaster cast of an Isotelus maximus trilobite from the Late Ordovician of Cincinnati, Ohio that I produce for my fossil club for sale at gift shops in the area. 100% of the money goes to the club and I bill the club for the materials. Sales have been kind of slow. It's not a popular item for some reason. Not sure, but my hand paining is a little splotchy and I guess people have been desensitized to replicas because of mass production. The plaster is just plaster of Paris I buy in a big bag at hobby stores. I first spray paint the whole thing, top and bottom with grey primer. After a couple of days, I use masking tape to cover the top of the shale, leaving only the trilobite exposed. I then spray paint it with dark taupe and then with the same paint in dark brown. I immediately wipe most of the dark brown off with a paper towel, leaving the darker colors in the grooves the same way you would see it look on a real Isotelus trilobite. A final touch before removing the masking tape is to buff the trilobite with a shammy cloth or lint free cloth. Yes, I have to touch up the shale with paint after I remove the tape. The tape does not do a perfect job of masking these fine details. Send questions to the Paleo Re-Creations Forum.

  22. After having a productive day on the ice yesterday (see Sub Zero Field Trip Report), I convinced my wife Alison to go out with me today. The temperature was a balmy 26 degrees Fahrenheit today. This time I brought a sled, my crack hammer and a slate bar. Instead of repeating the same trek I took my wife to a hundred yard long section of ledge where I found the negative of an Isotelus gigas the day before. Within 15 minutes of arriving Alison found a complete eight-inch Isotelus gigas eight feet up on the cliff on the under side of an overhang. She told me it was too bad we couldn’t get it. I told her that we would continue down the exposure and that I would try and get it on the way back in case I hurt myself trying to collect it. We proceeded down the exposure and collected several Flexicalymene senaria, a cephalopod and what I believe is a small colonial coral. One of the trilobites was behind a boulder leaning on the ledge, which Alison had crawled under. It was very tricky to extract. On the way back I climbed the cliff up to the Isotelus gigas and after about twenty minutes I was able to break the slabs free that the trilobite was on. Unfortunately one of the larger 30-pound blocks bounced funny and hit Alison in the thigh. Fortunately she had my smartphone in her front pocket, which took the brunt of the impact and dispersed the impact so that she was able to walk away without a bruise. I will need a new phone case however. On our long walk back we stopped where we usually collect and Alison sat on a rock. When I looked over at her I saw the largest Flexicalymene senaria we have ever found on its face. Unfortunately the fossil was on a very large rock. The good news was that it fit in the sled. The not so good news was that I had to make three trips up the hill with the sled and had to pull it up the hill to the car by itself because it was so heavy. I now have even more to prep this winter. I guess there are worse problems to have. Because of photo size I will post additional photos as separate posts.

  24. In 1970 I found an outstanding fossil location about 2 or 3 miles north of Oldenburg on the one road going through town. You stay to the left (west) and when you find the creek following the paved road on the west side... you are there. There is a turnoff that the farm's owners uses to take his tractor to the field and cross the creek. It is flowing all year round. The erosion along the stream bank has unlimited numbers of weathered out fossiliferous shale-limestone slabs with partial Isotelus and Flexicalymenes. The true treasures were in the creek bed shales when split, large Isotelus gigus were found in good numbers. Absolutely perfectly preserved and split well when wet. I would lay them out in the shade to dry out and the shell would not fracture and break off. They were all laying flat. The Flexicalymene meeki were rolled and flat. From pea size to that of a nickel in the shale and washed into gravel beds on bends in the creek. I told a person about my find when leaving Indianapolis while stationed there for a couple months. They came back, or someone they obviously knew and paid the farmer $500 to "quarry the location" out. The farm house is about a mile north and a turn to the east. I could not find the name of the farmer, who would be deceased by now, but his nephew was the next of kin and is probably working the farm today. New homes were being built in the area as well along the east side of the road. Inquire to the current owner of the field and you will then have the right person to ask. Since I FOUND THIS LOCATION I am offering this to anyone interested. But, please respect the property rights of the owner and if there is a current fossil collector leasing a part of the creek bed. I am sure there are lots of specimens to be discovered in this brushy slow moving creek. After 44 years the memory is very clear to me. I did not realize I had discovered a unique spot in an area that would not have been discovered by any method but by accident. I was at the Tucson Rock Show last February and saw a 12 inch or so Isotelus mounted on the wall with "inquire as to price" and a person interested. It said "Oldenburg, Indiana" and he was the person who had leased this patch of ground. He sold it while I was there. Once you can GPS the elevation of the strata, there could be other sites available to work. I just remember this farmer riding his big tractor down the road to see what I was finding that day. I gave him a very large Quartz Crystal many years later when I took my wife to see this spot... to discover it had been bull dozed out. You cannot get them all, I say. Good luck. Check with the current owner and be prepared to find all the slabs you could ever carry washing out of the creek bank and maybe... there are some trilobites missed in the tailings. I am sorry I have no photographs, but might have some color slides that can be digitized if there is much interest. You might have heard of Waldron, Indiana and the Waldron Shale. This location did not have any crinoids, but sure had all of the partial trilobites and scattered brachiopod shells you could ever expect.
