  1. So I got out of work early yesterday and headed off in hopes to find a few trilobites. I started off by finding a flexicalymene, and another. Then it happened! I found a fraction of an isotelus! I was stoked and ready to head home! On my way back to my vehicle I figured that I would look for more. I stopped and stared up the slope and out of the cornet of my eye I spot it staring out towards me! I quickly and carefully remove it from the ground, which made me even more stoked! Here are a few photos!
  2. Hiya everyone someone’s selling a trilobite, but hasn’t got a name or locality, normally I can tell straight away if a trilobite is real but the pictures aren’t the best and it’s like no trilobite I’ve seen, not sure if it’s a replica or a fake made to look like a isotelus.

    a special trip today

    I was fortunate enough to be invited to a Christmas party hosted by Dan Cooper today. I arrived not knowing what to expect as I had never met him, let alone his friends and family. It didn't take long to figure out that I was with amazing people. Everyone there was so laid back and had a passion for fossils and fossil collecting. Dan is by far one of the most laid back and nicest people that I have met. He took the time to take me around his facility and show me fossils that were being prepped and parts of his collection, as well as introducing me to his friends and family. I can't say enough about this guy and the people that were there! Anyhow, a few photos from the visit.

    around 2 months of learning

    I gained interest in this way late in life but can't get enough of it! Thanks to the books that members have suggested, many videos that I have watched, and all the knowledge this forum and it's members provide I have learned a bunch, and want to thank everyone that has taken time to help me . Not long ago I was in search for my first trilobite, and while cleaning things out I was shocked at what I saw. Here are some of the flexis that I have gathered since joining this site. It blows my mind! I have met a couple members so far, and hope to meet more in the future. You guys are amazing! Thanks you all!
  6. Got out early and drove to check a spot out. Found a broken isotelus that is preserved amazing. Couldn't find the other part. Maybe next time. Will add photos when I get home.

    giant isotelus

    How big would this isotelus had been? From tip of Cephalon to end of damaged genal spine is 13.9 cm.. Super stoked to have found it! Now I am not sure what to do with it, hahaha
  8. Went out today and found what I believe to be a very small headless isotelus. Also found some flexis, and various other things. Here are a few photos from today.

    Is this an isotelus pygidium?

    Found this today after work, believe it is an isotelus pygidium. Is that correct?
  10. I have been busy working, and fossil hunting, and haven't been sharing as much as I would like here on your forum, but have a story to share. Yesterday I arrived to hunt for trilobites early in the morning. I started off hitting a couple areas that I had noticed the day before. I wasn't there long and heard voices approaching. I looked up and a man was almost on top of me. I stood up and we started a conversation, he asked if he was encroaching on me. I told him not at all and he was more than welcome to hunt alongside of me. He then told me that he was a professor and he was doing research with a student. He asked me what all that I had found and I explained to him that I was new to fossil hunting and that I didn't know most of what I was finding, but was mainly after trilobites. He then offered to ID what I had collected if I would show him. At that point I had only kept a few brachiopods. He explained what they were and started to tell me of areas to go to for trilobites, as well as other fossils. We of course talk about trilobites and I tell him of two people that I had ran into that had both told me that they had found isotelus rollers there. One person from Wisconsin that found a baseball sized specimen, which he had shown me photos . Another was a hoosier that showed me photos of a smaller roller that he had found there. You could tell by the look on the professor's face that he thought that both people were pulling my leg. He then told me that he had been bringing his students there for many years and one of the things that he would offer them, is that if any of them would produce a full isotelus he would reward them. His student approached I thanked him, and told them that I wished them luck and started climbing a super steep loose rock incline to get up higher to what looked to be good to me for trilobites. Part of the way up I started seeing micro areas of interest and started bouncing from one to another on my way. Next thing I know I spot something that catches my eye. Bend over and pick it up, and about fall over. It is an isotelus! I stand there in amazement and inspect the small trilobite. Normally I would continue hunting. But I knew he was still there with his student so I head his way. I shout down to him and say, "you will never believe what I just found". He asks what, and I tell him. Him and his student quickly scale the hill and inspect the isotelus. He then says, "I would have to pay up for that one". There is more to the story than this. But I just think that there was something to finding that fossil. Had they not shown up, I would have not scaled the hill via the route I did. The fact that he didn't seem to believe that the other's had found the isotelus. The fact that I spotted it amongst the rubble that I did. I don't know, it just seems strange to me. Is Karma real?

    my first whole isotelus!!

    Just found my first isotelus! Will add more photos later, still hunting but so stoked, had to share!

    hopped out for a quick trip

    Hopped out for a short time today. Just wasn't feeling it. But I plan on going back out soon. But before I left I did find some flexicalymene partials, a bunch of isotelus fragments, including the mouth plate that I kept in the photo. I also grabbed a few cool hash plates with a good variety on them all.
  13. Disappointed, I did not find a whole trilobite today after work. But I found loads of partials and what I believe is a large section of isotelus in matrix. In your opinion would it be worth messing with or just leave it where it is? Here are a few photos from today. One good sized cephalopod, you can see part of it inside the matrix to the right of the exposed section.
  14. So I am setting outside having some adult beverages and whittling away at this rock. Have exposed a few, but there is a good sized partial of a trilobite that it's bottom is exposed on top. How would one go about this? I would really like to have it right-side up if at all possible without damage. Is it possible to fill the bottom (exposed) and work from the other side of the rock to expose it?
  15. Newbie_1971

    Isotelus, could it be?

    Quick hunt after work, and found this. Hoping it is an Isotelus head. Had nothing with me so dropped lighter next to it and my fingertip. Possibly head fragment with spine running under the matrix and broken tip at my fingertip

    Isotelus gigas

    From the album: Swatara Gap

    Collected by Kerry Matt in 1987 at Swatara Gap.
  17. Today I went to visit a friend of mine who purchased a flat of swatara gap material recently from an old collection. After hanging out and chatting for a bit he mentioned he had something to show me. He revealed a flat of incredible material to say the least, Two Acidaspis, a nearly perfect 3 inch Isotelus, and a massive Taeniaster flanked by two carpoids. The other specimens in the box were more common but impressively complete. I made an offer on the spot, after negotiating for a little we made a deal and I went home with the collection I knew most of the specimens had been collected by my good friend Kerry Matt as he had mentioned the specimens to me while collecting before. After talking to Kerry we agreed I’d return a few of the specimens to his collection in a trade. While I have all the specimens I thought I’d share them as they the species are often never seen from Swatara. See attached images of the specimens for the details. For context about Swatara Gap read: R.I.P Swatara Gap Top to bottom: Isotelus gigas: collected by Kerry Matt in 1984. Acidaspis cincinnatienis Acidaspis cincinnatienis Taeniaster spinosus with 2 carpoids belonging to the genus Ateleocystites. Ateleocystites Ateleocystites note the intact tube feet on the brittle star arm next to it.

    Isotelus injuries?

    This is a molt fragment of Isotelus sp. that I found in the Drakes formation in one of my usual spots. I've found isotelus pieces before, but this one is odd to me. In particular, I don't know what the lines on it are (not the cracks, I have the lines I'm talking about outlined in the pictures). I thought they might be a possible injury but I'm not sure.
  19. Fullux


    I found these two pieces in the Drakes formation of Louisville, Kentucky a little while ago. I'm 85% sure that these are molt fragments from Isotelus maximus but needed a second opinion. One could argue that these are simply iron coatings on pebbles, but if you look at the second one, the "coating" dips down into the pebble, and is also mixed in with a few other fossils such as vinlandostrophia. Then again I could still be wrong, I have been before.

    Isotelus gigas

    From the album: Purchased Trilobites of Isotelus2883

    Isotelus gigas from the Walcott Rust quarry. It is nicely inflated, but not very well-preserved. I got it for next to nothing though, so no complaints.

    Isotelus gigas from NY

    Hello everyone, I just wanted to share some pictures from 2 trilobites I just got back from the prep lab! They were collected in February by me and @KompsFossilsNMinerals at Lafamilia quarry. Top to Bottom. 6 inch Isotelus gigas Gravicalymene sp.

    Penn Dixie and Trenton Group Trip

    Hi all, about 2 weeks ago during my spring break my father and I made the 6 hour trip up to Buffalo NY to collect at Penn Dixie. Our main focus is to bring back blocks for our weathering pile in the back yard, so we worked from around 11am to 5pm moving chunks and transporting them to the car. Here is a photo of me driving a wedge into the huge row of rock we were working on, it was pinned and took probably 30 min and a lot of thinking to break it free. Ill attach photos of some finds from the day below. Disarticulated Eldredgeops and a complete Greenops (I have done some exploratory prep and uncovered a genal spine) Another Eldredgeops This beautiful prone Eldredgeops had an unfortunate encounter with Murphy’s Law, and when I tried to split down the chunk to a more manageable size the whole bug shattered. In hindsight I should’ve just deadlifted the rock as a whole into my wagon, but hindsight is 50/50. The next day was a bit short, we had pretty much ran out of room for chunks and I was sunburnt and fatigued (Despite regularly applying sunscreen and drinking lots of Gatorade). If you zoom in on the image below you can see the sunburn on my arm. View of the spot we were digging before we leave (Kompsfossilsnminerals for scale) As we were packing up, I started tapping on some of the rock from the layer above where we were working. On my second or third chunk, this beautiful Eldredgeops rana popped out! Only missing a little of the cephalon’s shell as well as an eye, which I think I can recover from the negative. 1/2
  23. Hey all, I am looking to add two new species to my collection. I would like a Dipleura and an Isotelus. Also interested in most any Asaphida species. Preferably complete / relatively complete (Rollers are fine) Please DM me photos if you have any you are okay to part with and we can make a trade.
  24. Bringing Fossils to Life

    Unknown fossils from the Coburn Formation

    Recently I went fossil hunting along a road cut revealing some of the Coburn Formation, latest Ordovician. I was stunned to find that so much of the ecosystem was made up of only Trilobites and Cephalopods. I found trilobites such as Isotelus and Cryptolithus (First picture). My find of the day was a large, very heavy plate of rock that preserves different parts of large Isotelus gigas from multiple individuals, and the circular cross-section of a small cephalopod (Second picture). However, I'm having trouble identifying these cephalopods. In the very few that preserve the outer sell, faint striae can be observed. The septa, when visible, are close together. On some of the smaller specimens, which may be a different species or the same, the uncrushed cross-section reveals what appears to be a small, eccentric siphuncle (Sixth picture). Most specimens, because of their size, are crushed flat. Only much smaller individuals sometimes retain their original shape. Arrows indicate septa unless stated otherwise. The large cephalopods appear similar to both "Michelinoceras" and Geisonoceras tenuistriatum, but this species is restricted to the Whitby formation in Ontario. Could anyone help?
  25. Nautiloid

    Huge Isotelus gigas

    From the album: Nautiloid’s Trilobite Collection

    This bug is in rough shape but I still kept it due to its massive size. It would’ve been 10.5-11.5 inches long if the bottom half of the pygidium wasn’t MIA. As you can see, the left half was exposed to the elements and is heavily weathered, but the right half is still relatively salvageable. This is by far the largest trilobite I’ve ever collected! Collected 11/04/2022
