I have found a couple of trilobites on a friend's property near Eganville, but I don't know what the attached fossils are. I am pretty sure the last one is a number of shells, but any ideas on the other ones? Thanks,

Hi - this is my first post to this group. I found this partial trilobite fossil this past summer in Ordovician limestone near Eganville, Ontario, Canada and I am hoping that someone here can help me identify the trilobite species it belongs to. This piece measures 3.5 inches in length by a little over 2.5 inches wide and I believe it is the pygidium and most of the thorax (so a little more than half of the full trilobite). Also, it has a little over 1/2 inch in depth, so it is not completely crushed flat. I would have much rather found a full trilobite - and I do have a full trilobite that I found that I am having prepped, that I will post at a later date - but I am very happy with the size and condition of this sample. I broke it out of the rock in this condition - no prepping has been done to this sample. Any thoughts?

I was recently reorganizing my fossil collection and thought I would share some pieces I collected during Paleontology field trips in undergrad at Alabama. I'm glad I took thorough notes at the time! The demopolis chalk is a popular formation for finding Exogyra/ostrea/pycnodonte shells and shark teeth. We visited a site in Tupelo, MS many times for surface collecting. Some of the cool pieces I found were many fragments of a mosasaur jaw (top pic, top 2 slots), a Squalicorax kaupi tooth, a scyliorhinus(?) tooth, bony fish vertebrae, and bony fish teeth. I was told the dark fossils at the right of the third picture might be ray plates, but I'm not sure. Turritella in pic 1 are from a different formation.

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. I have seen numerous folks on here show some of their finds from the Ordovician and Devonian of Iowa and nearby states and it always looked intriguing to me as I have collected the Ordovician in the (relatively) nearby Cincinnati area and the Devonian in the Great Lakes area and Oklahoma. I wanted to see how the Iowa stuff compares. So my wife and I opted to take the long way home from Indiana to Texas and swing through Iowa (and on to South Dakota, but that was more for sight-seeing). I had done some research on sites to check out and contacted Mike @minnbuckeye to see if he could help me high grade my list. Being the absolute gentleman that he is, he did one better and offered to act as our tour guide for a day of collecting through the Ordovician! What a guy!! I can’t thank him enough for taking the time to do this. We had a great day and hit a bunch of nice spots, most of which I had not found on my own and certainly didn’t know some of the very important details of the sites. Many folks have said it in other trip reports and I can only add to the chorus of how valuable it is to go with someone that knows the area and how nice it is of TFF members such as @minnbuckeye to offer their time and energy to do it. Based on Mike’s recommendation, we spent our first day doing some collecting in the Devonian rocks of the Coralville, Iowa area. The first spot we could not access due to some current road construction but we made our way to the next one and spent several hours along the Iowa River/Coralville Lake collecting from the Coralville Formation of the Cedar Valley Group. You quickly learn how Coralville got its name as the rocks are a coral/bryozoan limestone. There are brachiopods and other fauna, but corals make up the bulk of the fossils at this site. And there were some very nice ones as you can see in the pictures below. Beautiful Hexagonaria, huge horn corals and others. We also went to the Devonian Fossil Gorge and a nearby state park, both of which have nice exposures of Devonian rocks with fossils, but no collecting. Here is a shot of the area, fossils litter the ground. This represents our total haul from this site The horn coral in here were abundant and quite large. Corals What I believe are Hexagoanaria corals. I think with a little cleaning, these will look really nice and I like the juxtaposition with the horn coral. Brachiopods and bryozoans A nice piece that was a little too big to take.

This is a specimen from the strata near the top of Fossil Mountain/ Ibex in Millard County, Utah, USA. ( Ordovician- Lehman Formation) This is as-found 17JUL19 , no prep was done as I thought the weathering was beautiful just the way it is! Lots of interesting stuff in there, bits of various trilos, bivalves, ostrocoda,and lots of those coiled and partially coiled critters I have yet to identify.

Nice specimen of this interesting trilobite. The species name titan refers to this species being significantly bigger than the Czech typespecies Declivolithus alfredi. The distinctive head-shape of this suspension feeder shows this trilobite was probably adapted to fast swimming. Here's a paper describing the new species and the type locality: http://www.geology.cz/bulletin/fulltext/1649_Fortey_170930.pdf

Living at the confluence of the Missouri and Mississippi Rivers, we're used to spring floods. Last year, though, it was a whopper, second (barely) only to the Great Flood of 1993. It was months before the water receded, and when it did, I went up the River Road to Grafton IL to see what I could see. There's a little exposed ledge right at the edge of town, with towering bluffs across a grassy area behind it, and to my surprise this was lying on top of the ledge. It has a fossil-y look to it but I mainly collect Ordovician seabed things and I can't recall seeing anything that looked like this, or that had the size this thing has. I'm attaching a map showing exactly where I found it and what the strata in the area are, hope that helps, but honestly it looked like something that might have been carried down from some unknown place upstream by the flood, and just deposited where I found it. Thanks for any insights!

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:

I'm just easing back to regular life after a week of fossil collecting in the province of Quebec. We had a fantastic and highly productive time. There are a number of sites that I cannot mention publicly, and also some excellent specimens that I am sworn not to post anywhere, but I can show a few things. I haven't photographed everything yet, either. We collected mostly in the Neuville and Nicolet Formations. The first stop was Kingston, Ontario where we met up with a fellow fossil friend for a brief time. I obtained my own physical copy of Isotalo's book. I then meandered to a rock pile and spotted what would be the first of many trilobites on this trip, a battered Raymondites superbus in the Gull River Formation.

Cool Moroccan trilobite, maybe retouched?
Max-fossils posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hey guys, Saw this very nice looking trilobite for sale at a reasonable price, so I’m thinking of buying it. However I’m curious to know whether or not the specimen may be fake/retouched/in any way artificially handled. What do you guys think? Thanks in advance!

Last week me and some friends went to a couple of localities in Virginia! It was a nice change from collecting in the heat. Came back with boxes of Ordovician-age fossils on Monday, Tuesday, and Wednesday then went to good 'ol Purse for shark teeth the rest of the week and weekend. Came back with quite a few well-preserved brachiopods, graptolites, and a few fragments of trilobites. So many ray plates and a few shark teeth from Purse. I'm backlogged for weeks! Too tired to bother writing properly.

Hi guys, I recently purchased some processed Harding sandstone, I was looking for unprocessed stuff but I could not find any for sale so I had to just go with this. The fossils arrived today and I have been examining them with my microscope, I find this stuff very fascinating. My question is regarding these fossils here: the ID guide that came with them claims they are sharks but I find this strange, I believe chondrichthyes only appeared in the Late Silurian so how could this be? Are they something else, and if so do we know what that something would be? Also if they are sharks would we not also expect to find their teeth, yet they seem absent in this matrix. Thank you, Misha

9-15-20 and 9-16-20 Ordovician Collecting in Northern Kentucky and Southern Indiana
Nimravis posted a topic in Fossil Hunting Trips
I was on vacation this week and had to do a little remodel in our half bathroom, but I did make enough time to make a 5 hour trip to Kentucky and Indiana for some road cut collecting. My first stop was in Wilder, Kentucky, I love this first stop because I always find some story book hash plates. I have to admit that hash plates that have a lot of things going on are some of my favorite fossils to find. A lot of the pieces shown in this post ended up in the buckets of fossils that I brought to the ESCONI Braceville Shaft Mine trip on Saturday. Here are a couple pics of this location. One thing that I have to say about this location is that I do not find a lot of loose fossils here. I do not know if it is just me or that I am just gravitate to the hash plates that I find here. This is the only location that I find Graptolites, here are some pics. I picked up this piece because it reminded me of a Cruziana, I have some in my collection, but I have never actually found one. What do you think? Here are some burrow traces, they are all over the place. Here is another trace fossil, I forget the name of these. I did pick up a couple pieces that had long crinoid stems. Bryozoan are found here as well as pieces of Straight shelled nautiloids. Another thing that is special about this site is are the Cryptolithus trilo-bits that I find. I find these trilobites very pretty and love the lace collar and I don't recall if I ever found them at other locations. Here are some hash plates with them as well as Flexicalymene trilo-bits and other things. CONTINUED ON NEXT POST

From the album: Trilobites
About 7 cm in length, mislabeled on purchase as Mucronaspis zagoraensis (a formation mate). Confirmed by SM as D. socialis, and particularly on account of the blunted/absent genal spines. -
Found this the other day in Eastern Ontario and I'm not quite sure what it is. I asked on reddit and someone suggested it could possibly be a crinoid holdfast, but I wanted to get a second opinion just to be sure. Ordovician, about 2.5cm in diameter.

It has been 7 years now since I became hooked on the "fossil thing". My hunts seem to creep a little further from home with each passing year. Greener pasture syndrome. So a few days ago, I purposely started my adventure close to home. Here are a few finds from the Ordovician. @ClearLake Let me start with a few unknowns: This last one could just be a squished brachiopod, but seems to be a coiled organism. IDed as Trilobite eye, probably Isotelus The pygidium pictured came from a new spot I tried, expecting to find Isotelus. The pygidiums look more like Bumastus???? Actually IDed as Homotelus(?) florencevillensis. Again, not Bumastus, but Homotelus(?) florencevillensis. The trilobites came from the Maquoketa, the others from the Galena. I collected a few brachiopods (Galena) to please @Tidgy's Dad The Galena locally has many gastropods.

Hello everyone, I recently went on a trip to Pennsylvania and stopped to do some collecting in the Salona formation, I found some decent Cryptolithus parts which I am currently preparing, but most of the fossils were brachiopods. There were two types from what I could tell, smaller strophomenids and larger ones. The smaller ones I have not been able to get any ID info for but the larger ones may be Rafinesquina. Here are some of the small ones:

I found this strange form in a stone from ordovicium. The size is less than 1 cm, never seen anything like it. Look almost as it is artificial but it is a real fossile. Any one have any idea what it can be? Martin

Hi guys I recently found this nice sized Pholadomorpha pholadoformis at the Humber River in Etobicoke, Ontario. It belongs to the Georgian Bay formation and is late Ordovician in age. The specimen has pyrite in addition to the black film. Does this fossil have some sort of pyrite disease to it?
