Some new finds from an exploratory trip to Southern Illinois and Missouri. Originally I was focusing on Silurian rocks, but wasn't having much luck. Mississippian fossils Kaskia chesterensis Richmondian stage fossils Missouri Conulariid impression. Very beautiful magnified. Haven't had much time yet to look up names. Not sure what this species is. Very small, just a few mm. Thanks for looking!

A couple more Platteville Formation Grant Co. Wisconsin Trilobite and some others
SteveRogers posted a topic in Fossil ID
Hello, I had some time to look at a few more of the rocks from my collection trip into Wisconsin Platteville Grant County 1,2,3 First is a flat creek rock I gave a scrub and I think it has a trilobite cephalon. 4,5,Is a rock that appears to have a trilobites or it coiled be a broken bivalve? It's in a flakey rock so I haven't picked at it much. I included a side picture of the sediments. 6,7 I am pretty sure these are Chondrites? Or something similar? There are also some other bits in it 8 is a bit of hash plate but it has what I assume must be pyrite bits that are a bit flashy golden - hard to see in the pic but there ar little bit popping out and reflective - I figured I before I show my daughter I figured I should confirm they are pyrite or something similar - and not what she will immediately think it is! Thanks and I hope you all have a wonderful weekend! I'll keep sorting and seeing what I got and maybe walk a creek or two for fun

Both my brother and I celebrated graduations this year - my brother graduated from college and I graduated from law school. In celebration of our graduations, we decided to take a 13-day road trip to see some of the United States after I had taken the bar exam but before I began work. Our journey ultimately took us through Atlanta, New Orleans, Houston, San Antonio, Austin, Oklahoma City, St. Louis, Dayton and Pittsburgh, before returning home. Our days were jam-packed, with us often not arriving at a hotel until 9/10pm, but along the way we did find some time to make a few quick stops to collect some fossils in Georgia and Texas. My brother is not a collector, but I was really excited to try to find some examples of the infamous Georgia trilobites, Texas echinoids and Texas ammonites. I want to thank @BobWill, @smt126, @facehugger, and @JamieLynn for answering my innumerable questions about Texas fossils. We ultimately did not have enough time to check out all of the places you suggested, but I will certainly store the knowledge for my next trip - hopefully in cooler weather. Our first stop was at Tibbs Bridge in Chatsworth, GA. Having heard the rumors about the potential illegality of the site I was a little worried when we arrived. We could not initially find parking and when we pulled off, we picked the wrong spot. The homeowner we parked near came out yelling at us about collecting beneath the bridge and threatening to call the police. Having driven all the way from New Jersey I was not yet ready to give up on the trip. We decided to pick another spot to park and given that my brother doesn't collect, he waited in the car in case something happened. We could not stay at the site for longer than 90 minutes, so I tried to find as much as I could. As a funny aside, I was soon joined by another group of collectors from Georgia, one of whom had recently spent time in my hometown in New Jersey. Small world! I was hoping to find some better preserved trilobites, but I had to ultimately settle with some nice impressions and a couple of smaller fragments of exoskeleton. I did find one large trilobite that still had all of its exoskeleton, but it was fractured and I could not put it back together even at home. I was able to keep the impression of the trilobite though. All of what I found were Aphelaspis brachyphasis. And the large trilobite whose exoskeleton was simply too damaged to repair

I grew up in St Charles county, Missouri. I am in my fifties now and have a wife and two kids. We like to get out and fossil hunt when we have some extra time. From the age of about 8 I started collecting crinoids, horn corals and brachiopods from every stretch of creek gravel I could find. I have a whole bucket of these I will post some photos. Found a couple trilobites and a couple of pretty nice blastoids. I can post some photos of those. Also found a few that sort of look like oats. And a few that look like a little flat round crinoid size disk with a notch out of the side. But I have a couple of larger fossils I cannot identify, both found here in missouri St Charles County and Warren County. One looks crinoid-like except its almost the size of a small loaf of bread and has no hollow center. The other looks like maybe part of some plant about the size of a fist. I will be posting photos of these to see if anyone has an idea.

Hey all, I bought this trilobite from a seller today and was wondering if anyone could help me ID it. I'm pretty sure its from Utah, and I think it's an Elrathia, but I just want to get some other thoughts or opinions. In the bottom left there seems to be part of an agnostid, but I could be wrong. The seller said that they didn't know where it came from unfortunately.

When I got home from work today one of my neighbors called and asked me to come over to his house, when I arrived I saw that he had 3 large containers of fossils, rocks, etc. He reminded me that several years ago I gave 2 of his kids some fossils and that they recently went through them and kept what they wanted and asked me if I wanted the others back, of course I said yes. I cannot tell you what they kept, but I think there were a couple Oreodont upper skulls and probably a couple other cool pieces. Here is the stuff I brought back home. Most of the trilobites I believe are from Utah. I know the first large one is from Morocco and another is from Canada. If you know of any of the ID’s and you want to mention it, please feel free to do it. There were a lot of Mazon Creek fossils and a couple unopened concretions. Here are other pieces of Mazon Creek fossils. Here is a large Jurassic ripple mark plate from outside of Sundance, Wyoming. Here is a not very good example of Knightia fish from Wyoming. Mosasaur vertebrae- Dinosaur Bone- Belemites- Continued on next post.

Hello everyone, thanks for letting me join the site! I'm an amateur fossil hunter from Toronto who has made a few expeditions in the past months. I've found a few fossils of interest that I'd like some help identifying. Below are links to photos of the fossils in question on my iNaturalist page, along with some additional details. Thanks all in advance! The following were all found along the Don River in Toronto. 1. https://www.inaturalist.org/observations/68570190 2. https://www.inaturalist.org/observations/68573964 3. https://www.inaturalist.org/observations/68570193 4. https://www.inaturalist.org/observations/68300323 5. https://www.inaturalist.org/observations/68573819 This was also found in Toronto, in a clean fill pile. A nice assortment of small invertebrates here. 6. https://www.inaturalist.org/observations/19866874 This one is a real mystery. Also from Toronto, among clean fill. A bone fragment? A piece of vegetation? Coral? 7. https://www.inaturalist.org/observations/68299911 These three were found today in Prince Edward County... 8. https://www.inaturalist.org/observations/69519088 9. https://www.inaturalist.org/observations/69532565 10. https://www.inaturalist.org/observations/69519075#activity_identification_0484c99a-6655-4e0f-8a1c-2ab2cd4c0fea And finally, this Trilobite fragment was found in the vicinity of Arkona. 11. https://www.inaturalist.org/observations/68299694

Hey guys， I‘ve dug out some ’fossils‘ that I can't say for sure on a hill of Hubei Province,China. According to the local geological document,there’re exposed strata of middle Devonian and lower Permian around this area. There are some rocks with special patterns on it, which looks like trilobite and shellfish. On another rock, I can see a patch of dots, just like a tentacle of starfish. On this hillside, I also found some strange rocks in the shape of ’flat cylinder‘, with irregular patterns on them. I think it may be the remains of some kind of ancient creature. But I have absolutely no idea about what are them. I'm new in the field of fossil. And his is the first time I sign up The Fossil Forum, so I believe everyone here could teach me a lot. Thank you so much！

Hey everyone, I just got a small lot of trilobites in the mail and I’m not really sure what I’m dealing with. It wasn’t very pricey for these 5 bugs plus a low grade Moroccan trilo that I know the ID of. So I figure I’ll buy now ask later lol. these 2 seem to be the same trilobite I’m just totally unsure from where. I’m guessing China maybe? pretty sure this is the well known Pseudogygities from Canada...or maybe it’s a similar genus? these almost look like cousins to Olenellus with the body plan. Seems like a Cambrian bug but i don’t really know for sure. Maybe another Chinese trilobite? apologies for lack of scale bar....not sure where my ruler went so I had to settle for a not so great pen for scale Thanks!! Hopefully someone knows for sure! Al

Hi All, I have recently started my fossil collection, I am still figuring out what I really enjoy and what fits in my budget, but atleast trilobites really got my interest. I have some experience in collecting in general and I decided to buy nice specimens, especially for the common trilobites, rather than starting off with less preserved ones and having to upgrade them in the future. I want to share my first two trilobites: If anyone has any opinions and information about them, please do not hesitate to do so! My knowledge is still small in the fossil world. This one was sold as a Morocops Granulops (Devonian), excavated in Jbel Zguilma Marocco. The second one is a Asaphus lepidurus (Middle Ordovician), excavated in the Putilovo quarry Russia.

With 2020 over with its now a good time to look back at the year. It was a decent year for fossils. I explored many new spots and was able to meet many new people, 6 feet apart of course. With the diagnosis of tendinitis i was not able to dig much this year but i was able to make the most of it. The first thing found since my last post was this epic bryozoan colony. It came out of the very top of the Wanakah shale and weighs almost 8 pounds. Im unsure of species but I think its pretty cool

Taking advantage of my time spent home, I finally got a couple of glass display cases to showcase fossil specimens from my collection. Finding ones that were affordable and blended with the style of our home, was challenge, and I took my time choosing. Despite a bit of criticism I receive from some of my fossil collecting friends, I am a generalist collector who doesn't specialize in anything. Having said that, my collection does feature some rare faunas; Devonian and Cretaceous bivalves, Lower and Middle Devonian brachiopods and gastropods, Cretaceous vertebrates, etc. The focus is largely on fossils of the Northeast (New York, New Jersey, Pennsylvania, Connecticut, Maryland, and Eastern Canada), but a number of trips to the Ohio Valley, Texas, out west, and Germany have expanded my collection which is about 90% self collected with remaining fossils primarily gifts from generous friends. There is only one purchased fossil in the display and one I traded for. I ended up with twelves shelves- ten devoted to animal life (seven of those are invertebrates), and two for plants. I was seeking to emulate the old style of specimen display that one might encounter in a 19th century museum, when displaying specimens was the priority. I didn't and couldn't display my entire collection which is too large, so I picked representative specimens to tell the story of the vast variety of prehistoric life on earth. Some of my best specimens didn't make it into the display. These are the cases which are situated in our finished basement:

I received some Waldron Shale trilos for prep today. As always I made a brief examination of the matrix in search of any other fossils. I came across these, that I think may be cross sections of bugs? I should clarify that I have 0 experience with such cross sections. If they were, I'd assume the smaller one is the standard C. breviceps but the larger is curious. It's about 1.75 in/4.5 cm across and appears to have tubercles. What do you guys think, am I way off base or have I found something interesting?

Cephalon partial from the needmore near winchester VA, middle Devonian. Looked familiar so I looked it up in the book I remembered it from and it lists it as unidentified, but resembling Lichas. As I was looking at it I noticed below it an illustration that looked just like a couple of tiny partials (pygidiums) I had saved from the same spot. Book lists these as unidentified too, but was published in 1991 so I was wondering if anyone here had any ideas. I’ve found a lot of damaged cephalon partials like this out there so if I know what the rest of the bug looks like, I can maybe keep myself from getting confused if I run into it while looking for something else out there.

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

Hey everyone, I’ve been meaning to get this post up for a few days but I’ve been dealing with my poor cat inky (Sweetheart of a cat) who is on her final day of life today. I will have to put her down November 1st. Very sad time as she’s been my companion the last 13 years. I’m sure many can relate. I’ll try to keep the chatter short and just get up as many photos I can for you kind people on the forum to enjoy. I just got back recently from an amazing trip to Utah and Nevada (Oct/11/2020-Oct/18/2020) Where I was camping in the field and trilobite collecting for 6 days straight. It was a very rewarding trip but it also required some serious gusto and hard work in the field. This type of collecting I did isn’t for the faint of heart with many days stacked on top of each other. With that I’ll try to get to the photos cause we all know that’s what we wanna see. These will consist of mostly field shots of finds during the first moments after discovery. My prep lab is under construction and it’ll be a couple months before I can start prepping these amazing bugs. First time to Utah requires pictures upon arrival. This was home....the nights got very cold and the days were comfortable but dry and sometimes kinda hot. Avoided some serious heat so I was lucky. This time of year is a little more forgiving in the desert. field shots incoming! It may take a hour or 2 to get them up.

Hello from New Mexico. I have always been interested in the diverse geology here in New Mexico. I am new to identifying fossils and am seeking spots in the state to explore. I have found numerous fossils in the Sandia and Manzano mountains. To my 'beginner' knowledge , most of these fossils are from the Pennsylvanian era. Very fun findings! I'd appreciate any knowledge anyone might be able to give about sites around New Mexico. Also what to look for in those sites. I found one site through this page for ammonites and am excited to venture out there soon. Thank you

I got some trilobite fossils that i found many are possibly complete bodies but how do i prep them? How do i know where the body starts and ends? I kind of know where the body ends because of the size of the trilobites. But not really what way it goes in the rock. Up down the side? It also depends on the rock. Its not shale its limestone from kinnekulle. What really worries me are the rib things i Will use dental picks and small and other small sharp hand tools

So i got a trilobite pygdium that i i will prep but under it theres not alot of matrix so i was worried that it would fall apart. So i put some cyanoacrylate on the back. Heres some pictures the dark is cyanoacrylate. But the question is is it needed to keep the trilobite whole when prepping?And should i put more on the back as i prep more?And after should i remove it with acetone? If It needs to be there to keep it complete how do i make transparent? I got 2 trilobites that look really flaky pieces of shell looks very flaky and probably will fall apart if i Touch it. How do i fix the flaking part? Also cyanoacrylate? And if so how do i later remove the cyanoacrylate without removing the flaky pieces? Theres a picture of one of the trilobites that looks flaky.

Hi Everyone, I took a 2 week trip to the Ohio Valley, arriving back in New York about a week ago. It was primarily a family visit since many of my relatives now reside in the Elizabethtown, KY area. However, the Ohio Valley, as some of you know, is very rich in Paleozoic fossils and I just had to make a few stops on my way there and back as well as between family engagements. I will try to share enough to give you all a gist of it: It was a long day's drive from the northern suburbs of New York City to Richmond, Indiana where I spent the first night. The next day I was headed down State Road 101 to Garr Hill, to collect in the Upper Ordovician Liberty Formation. It was my first time at the site and everything I found was collected from loose rocks at or near the base of the outcrop. A couple of pictures:

Does anyone have tips for visiting Lost River, WV? I looked at fossil guy's website for tips and decided I wanted more. Is it still accessible? I heard that there were some exposures along the way. Are there any worth my time?
