  1. Last weekend, I decided to venture out to my favorite site to find trilobites. It is a site better visited during dry weather, but I couldn't wait! I do not know which was muddier, the truck or me when I packed it up. Here is the location without the mud visable. This material is best approached by splitting larger slabs of matrix. The result is always a bunch of trilo-bits. This is a nicer hash plate found that day

    From the album: Trilobites of Minnesota Decorah/Platteville/Galena Formation

    Isotelus gigas thorax and pygidium from Galena Formation (thanks Kane for the positive id).
  3. I am confused about how to id Isotelus species as they all looks alike. I know I rex is out of the range for Ordovician Platteville/Decorah/Galena Formation. #1 is the most complete (minus head) from Galena formation in southern Minnesota. Its also the only Galena one I am showing right now as other still need cleaning. #2 The largest pygidium from Platteville Formation. Not the most complete I have but is pretty wide. #3 I am disappointed with the quality of pics but just showing here. Pygidium of smaller Isotelus species from Platteville with the farth
  4. 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.
  5. Greetings everybody! While I was on my fishing trip last weekend I took some time to look for fossils. I collected at a couple of creeks exposing the Middle Ordovician Trenton Group in North-Central NY. I found lots of trilo-bits and other goodies! Enjoy
  6. General question for the group: Would you rather find a large (large being over 8 inches, in my case), inflated trilobite with some damage OR a smaller, flat trilobite with very little damage at all? I know it would depend on the actual examples, but in general I was wondering what people preferred. I have a small one that I think is cool but the larger ones are just so much more impressive to me... I am just starting to collect trilobites, as I have only recently realized they can be found in my area. Thanks.
  7. Note: This is a follow-up post to my original post of about a week ago. I found this trilobite fossil near Eganville, Ontario, Canada. When I first picked it up, I thought it was broken but then I noticed that it was just slightly rolled and the pygidium was curved downwards. I have already posted a couple of pics of this Isotelus as found, but now that I have had it prepped (thank you Malcolm), it looks even better so I thought I would share.
  8. Found this trilobite this morning. At first, I thought it was only half of the trilobite but then I noticed that it was just folded over. Other than a bit of damage to one side, it is almost entirely intact and a pretty nice specimen. The attached pics show exactly what it looked like when I found it. If stretched out flat, it would measure 4.5 inches long. It is inflated, and is about 1/2 inch in height. The other trilobites I have found around this location have been Isotelus and I think this one is as well. Thoughts?

    I read a lot of fossil hunting reports on here, but I don’t post many. I think it’s primarily because it is usually many, many months after I have gone when I finally get everything cleaned up, ID’d and take photos, etc. It just seems too after the fact to me at that point, haha. But this time, due to a wonderful “tour guide” we had, I wanted to get something posted in a relatively timely fashion. Because of that, I haven’t had time to do a lot of research I need to do on specific ID’s but luckily I’m somewhat familiar with most of what we found to make at least an educated guess.

    Isotelus bits?

    One lives in hope. From one of my favourite hash plates, sent to me by my wonderful friend Ralph @Nimravis Southgate Hill road cut, St. Leon, Indiana, USA. Cincinnatian (Late Ordovician) Waynesville or Liberty Formation. Is this part of an Isotelus thoracic segment? Thank you so much for looking and any help is very gratefully appreciated. 11 mm across. And is this a bit of Isotelus? 2.2 cm long.
  11. I took a walk along Etobicoke Creek on the weekend and found some of the usual suspects!

    My Isotelus

    OK, so guess who's using this Covid-related down time to post the topics he never got around to? In late 2013 I visited the Mt Orab "trilobite farm". This was my 3rd or 4th time (and final) and, as were most, I was always fairly lucky finding something. I usually just "dug" in the area where the flexis could be found, once stumbling on the partial Isotelus shown above. This day I decided to lend a hand on the area where Isotelus' were more prevalent. As at Penn Dixie, long crow bars were pounded into the layered shale so that massive pieces could be extract
  13. Just wanted to share one of my favorite Trilobite Hash Plates. It contains pygidiums, pygidial spines and cephalons from Gabicerarus mifflinesis, a free cheek from Isotelus species and a cephalon of Bumastoides milleri. It's from the Mifflin member of the Platteville formation, Grant County, Wisconsin. Ordovician period. Hope you enjoy.

    Isotelus Pygdium

    From the album: Finds From the Ordovician -488 to 443 MYA-

    From the Georgian Bay Formation
  15. Yesterday I visited Etobicoke creek (west end of Toronto) which exposes the ordovician Georgian Bay formation. The creek was abundant with trace fossils and plates of preserved ripples, as well as small orthocone nautiloids.

    Isotelus Trilo Spots?

    Just visited the American Museum of Natural History, and one piece I saw there was a pair of Ordovician Isotelus Trilobites:l (iowensis?) Seeing this, I remembered that Isotelus Trilos were something that I was looking for. Anyone know of a site in/near Georgia?

    3 Isotelus Trilobites

    Had a great fossil expedition the other day. Found 3 rolled Isotelus trilobites.
  18. I only recently got into collecting after being out hiking and literally tripping over a large coral fossil a couple years ago and the hunt has been on since! SO much to learn! I wish I'd have started 30 or 40 years ago. I haven't posted any of my finds as I've been trying learn a little first and see if I could identify some of these. I think I've got some of them and others I haven't found a name for, so I hope you don't mind me dumping several on you. Are all these Receptaculites Oweni? They were found in the Galena dolomite in the Dubuque area in what I think is the Fairplay me
  19. 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 w

    Fragments of Isotelus?

    Hey guys I am curious if any of these are trilobite fragments. They are all very small and thin. Found in Ordovician rocks in Cincinnati. A piece was broken off because of too much water pressure so I outlined what it was like before. It is more brown colored. This piece is a pit more brown colored.

    Canadian Trilobite?

    I just found this guy hiding in the back of my collection. No idea how long he’s been back there, but I’m pretty sure I found him on the shores of Lake Erie, on the Canada side. Looks to be a weathers trilobite to me, possibly Isotelus, but, admittedly, I know very little about these bugs. Hopefully some of the experts out there can clear things up. Thanks! JPC
  22. My father was an artist who did quite a bit of sculpture in wood and stone. Unfortunately I did not inherit his ability to draw and sculpt. He always said that he basically knew what was hiding in the piece of wood or soapstone from the time he saw it. He said the animal or abstract work was always in there it was just waiting for him to take the crud off what was obstructing the view. Well prepping trilobites is very much like that . You need to figure out the best way to present the bug really before you start the prep. You need to visualize the end product. Here is a Plattevi

    Isotelus

    I found this last month on a visit to an abandoned limestone quarry near Naponee, Ontario. Though I am not very familiar with the Trilobites of this area, I believe it's an Isotelus. If I'm wrong with this identification, please tell me. It looks like there could be more of it underneath the sediment, and there is some matrix covering the pleura. This limestone is flaky and darker than any I have seen before. How would I go about prepping this? Though I've heard many people use sand, should I use something less abrasive, like baking soda? Thanks for the help.

    Isotelus ID

    I purchased this Isotelus labelled as the species gigas. The bug is 1 1/8 inches long. A friend that collects, buys, and sells mostly Cincinnati fossils thinks it is really the species maximus. The fossil was collected in the Kope Formation of Brown . I just want to make sure I label it correctly in my collection database.
  25. About a month ago, I headed out on two fossil trips to the well-known St. Leon roadcut in Indiana. I was hunting in the Liberty formation (late Ordovician) with the sole goal of finding some nice trilobites (which I definitely achieved!). Along with multiple rare trilobites, I was able to find some excellent examples of other fossils. The spoils were totally awesome, and I am itching to go back. I hope you enjoy. Best for last.
