    Is this part of a trilobite?

    Hi guys, I am not very good at identifying fossils yet. Its my main goal to find trilobite fossils because I think theyre really neat and I am wondering if these are possibly sections of a trilobite. I dont think there is a lot to go on but I was extremely impressed by the speed and ease that was required to identify my last find (thank you very much Kane!). There are two fossils, one is orange-y and the other is a darker grey and harder to see.
  3. Barely a month had gone by since my last trip to New Mexico and Colorado, but I already had plans for this trip in the works. Primary focus this time, which was a solo trip, was fossil collecting, visiting well known sites that have been on my radar for quite some time. I flew out to Salt Lake City and drove directly to Kemmerer, WY. My first stop there was Fossil Butte National Monument: Here is a view of the visitors center (free admission) and the surrounding barren, but awesome landscape that surrounds it:
  4. First sunny day of the week . Wife and kids getting slowly crazy while I have to deal with a higher than average workload from home. Hum ...time to steal a few hours with the two oldest ones and get back to the Nicollet Fm (ordovician ) nearby. This time Flexys did not make the cut , or none did with all parts intact ( except maybe one found by my eldest) . This Triarthrus Rougensis made my day though , the best (by far ) I found so far . Followed by another promising one later .2 and a half hours well spent! PS: wow , just noticed this is my first post since landing he
  5. Just got back from a trip to Forbes, NSW a couple of days ago. Found some great stuff! But after that we checked out a site mentioned very vaguely in an old paper and were pretty successful! The site which is located near Parkes, NSW has Late Ordovician trilobites and other fauna. From what I can gather most of the species from the site are undescribed(?). Anyway, here are a few of my finds, maybe @piranha could help out with some ID's. Oh and I haven't finished prepping these specimens, but I'll post them when I have, although it may be a while since my airscribe has decided to bre
  6. A while back, @Darktooth and I did a little trading. Somewhere in the mix, he mentioned that his educational outreach (and collection) would benefit from some examples of C. chubutensis. I sent a couple of examples and it seems all that cuspy goodness went to his head. I received a COVID care package from Dave a week or so ago that contained a complete New York fossil trip in a box! I was completely blown away and the objects have given me quite a bit of entertainment. The field-trip-in-a-box was complete with lovely hand written tags, so everything was ready to put right into a large riker bo
  7. Hello, I’m a beginner of collecting trilobites fossils, and I have bought one recently but seems it’s a fake trilobites. Can you guys help me plz. Thanks!
  8. A few weeks ago I went on a fossil hunting trip to Albany County. I was hunting in the New Scotland formation which is lower Devonian in age. It was very quick and easy to collect in and the dry dredging technique was quite useful. The rock was a very thin shaly limestone which could break easily but many of the fossils had been silicified, making it easy to pop them out of the rock. I found many different species of brachiopods, some gastropods, lots of corals and large bryozoa and a few trilobites
  9. Today on a hunt I found on of the most unusual trilobite pygidiums I've ever seen from new york and cannot find anything out there to compare it to. Unfortunately the site is imported material from an unknown quarry upstate so all I do know is that its from the Devonian of New York based on other material found there, unfortunately I cannot attach a formation to this one. Also its also fragile and a very partial piece thats unpreped, I think its a ventral display. This maybe a head scratcher so maybe the trilobite experts here can help weigh in on what this can possibly be.
  10. Hey everyone!! I'm writing in to see if anybody has a preference between Paulding fossil garden and Sylvania fossil park for finding trilobites. There is a spot at the header of this entry which nobody else has talked about that might yield some gems. Posts about Paulding seem like hit or miss trilobite presence. Which site would be more "picked over" do you think, if you do at all? I'm driving through Ohio soon and can only stop at one spot. Trilobites and microfossils are my priority and all else would be a great bonus. If anyone cares to weigh in I would greatly appr

    Trilobites from Sweden

    Wins from an auction hosted by my friend @Kasia These bits are in a medium grey limestone found at Raback, near Kinnekulle, Vastegotland, Sweden, so are probably from the Upper Cambrian part of the Alum Shale Formation. Maybe Peltura scaraboides? Or is there not enough left to get close to an id? Max 5 mm wide and 4 mm long. All specimens are on the same rock. The scale's in mm and is partially obscuring a bit seen better below : Not really expecting too much from these tiny fragments, but

    Three Unlabeled Trilobites to ID

    Being stuck at home has given me the opportunity to rummage through my fossils. I started with my trilobites. Weeded out three containers of Isotelus partials to give to the local sand pit. But I found 3 unidentified trilobites tucked in with the Isotelus for some reason.. Any help at IDs is appreciated. 1. Gerastos?? I think this was a gift to me many years ago. 2. Thaleops? Though I considered Illaenus or even Bumastus. The matrix looks like the Platteville, Ordovician 3. I have such difficulty with "rollers"!

    Are these the same?

    Are these two odontopleurid pygidiums from the same species? They don't seem to match up. Same locality, Maquoketa group.First one measures 4mm across and the second measures 2mm. I'm finding not much information on odontopleurids from the Maquoketa... Leonaspis? Any help appreciated.

    Big trilobite from Gore

    Found this big guy in Gore. The head was exposed so I kept chipping away hoping there was more to him, and sure enough! It took about an hour to chip away the surrounding matrix, and at the end I thought I'd have to break him to extract him fully, but I pulled and he popped out! Is he deformed or just big? The head looks kind of smushed. Apparently my pics are super large so I'll try to add a couple more in the comments.
  15. Spring of 2020 We took advantage of the time off and the break in weather to hunt one of our favorite streams here in Western New York. This was just a spring scouting mission to see what was exposed after the ice and snow has melted. Some of the more interesting finds were a crinoid crown (very rare for this locality) possibly Logocrinus, Spinocyrtia granulosa open with both valves, Orthospirifer marcyi, a large Megastrophia concava cleaned by nature with epibionts, and 3 small nearly complete Greenops. We also found many small Favosites coral colonies, large Heliophyllum corals, and 8 d

    Local Silurian

    Yesterday I decided to make a quick trip before the Illinois stay at home order took place. For the past 4 years I've been trying to find all 16 of the trilobite taxa in the Sugar Run formation. So far I've found 12. The lichids are eluding me, except for a partial Trochurus welleri found last year. Here is what I think is a lichid fragment (?) Dalmanities illinoisensis pygidium continued...
  17. Hello all! We are planning a trip (with a stop in Pennsylvania) to New York this May to hunt for Trilobites and could use lots of advice. We live in North Carolina, so it is a bit of a haul and we are new to trilobite hunting and to rock splitting fossil hunting generally. I'll lay out the tentative itinerary first and then ask a few specific questions. Any recommendations on the itinerary (additions or places to skip on a limited trip) are, of course, more than welcome! Tuesday Day 0: Drive to Danville, PA and check into a hotel Wednesday Day 1: Visit the
  18. Hello community, due to the coronavirus, Virginia Tech amongst many other schools forced evacuation of campus, so I was forced to go down to VT to quickly clear out my dorm. I ended up staying at my brother’s house for a few days with him and my girlfriend just to enjoy the peace of the empty school. Yesterday, my girlfriend and I drove down to Pearisburg and hiked to see the cemetery then to hike up the Appalachian Trail to Angel’s Rest. On the way down the Appalachian Trail, I began inspecting what I believe to be as shale and noticed a small shell imprint. I began fiddling around with
  19. Steadly approaching 3 years of collecting from dumped dolomite piles in Milwaukee County has lead to a plethora of "Calymene celebra" molts from Silurian Dolomite of the Racine Formation. Wenlockian. Many hours have been spent with a large sledge hammer breaking out mold of Calymene and other trilobites in similar ways to the Cedarville dolomite in Ohio. The trilobites are almost always complete and are in a noted molting position shown in Weller 1907 An example from my collection and prepped Over the three years we have collected over a hundred complete individuals from the dolomite.
  20. I started the "My trilobite of the week" thread in the Members Collections section as a way of getting myself to actually start photographing my fossils for the web site I am creating. I have many different types of fossils, but I only collect fossils from before the dinosaurs so that means lots of Paleozoic fossils and most of the ones I have are trilobites. As you would expect for a project like this I have been learning as I have been going along. I got my photography equipment for the specific purpose of photographing my fossils, so I have a different set of lenses than I'd have if I wa
  21. Last week I made my third annual pilgrimage back to the Chicago area to visit family, do a little fossil hunting, gorge myself on great ethnic foods and treat myself to some Chicago-style deep-dish stuffed pizza for my birthday--yum! I had hoped to pick up some more Pit 2 (Braidwood Biota) Mazon Creek nodules from Fossil Rock campground in Wilmington but sadly it is now closed and up for auction with the distinct possibility that it will never again allow fossil hunters to gather nodules from the spoil piles at the back of the campground. Instead, I figured on focusing back on the Pit 11 (Es
  22. Today on day 2, I spent about six hours in the on and off rain, near Lawrenceburg, Indiana collecting Ordovician fossils. I found numerous trilobite parts, but nothing complete. Things that believe are parts of trilobites- "Isotelus" fragments. These two pieces were on a very large block that was not feasible to try and move. I figured that I would try and get them out, but unfortunately, I was not successful . Many Cephalopods – Brachiopods- "Platystrophia"
  23. Hello all, I am curious to know about the techniques people use for producing photographs for plates in paleontological publications. I know there are some professional paleontologists on here, so I'm assuming some of you have personal experience in this area. What equipment in general is ideal for this? I have next to no experience with photography outside of taking pictures of my personal collection with a point and shoot. The reason why I am asking is because I will be required to do so for my undergraduate thesis research (photoshoot of some Lower Cambrian trilobite
  24. My great aunt gave this to me years ago, and I would like to know if it is real. I know there are tons of fakes, and would like to see if mine is real.
