From the album: Nautiloid’s Trilobite Collection
This little bug is only about 0.8 cm wide, but has pretty decent preservation. The rest of the shell is in the negative, and hopefully the rostral process. Lower Ordovician Ninemile Formation Nye Co., NV -
Hey everyone, hope you’re all doing well. I was on a walk the other day in a local nature preserve with my son when I stumbled across some fossiliferous stones in a pile. These contained mostly brachiopods, but one in particular had crinoids stems and another structure I wasn’t certain on. I’m not familiar with this place, looking up the area puts it somewhere in the Ordovician (either the conococheague, Stonehenge or stoufferstown formations) but these stones had been deliberately placed in a pile so I can’t say for certain if they came from the location or were brought in. So I have 2 q

I collected this trilobite pygidium in the Galena Group (Upper Ordovician) of Illinois. I don't immediately recognize it, especially since it is just a mold. It is fairly large. My best guess is Isotelus but I was hoping one of the trilobite experts here might have a better idea. Thanks for any help.

I found this buried in the water in Joshua’s Creek, Oakville. This giant rock containing many coral fossils and a couple of Orthocone fossils also. I’m certain the fossils are Ordovician in age. Measurements are 30cm in length and 19cm in width. Can anyone help with identifying the Orthocones and Corals down to species pls? This is my biggest find yet, so excited to hear everyone’s opinions!

Here's a find from last summer. I originally classified this as a nautiloid, though I think it could be a horn coral too. Unfortunately I'm not very familiar with the inner workings of either and I can't see much that could point one way or another. I do think it's a nautiloid judging by how straight it is, but I would appreciate feedback from anyone with more experience.

I found a couple of fossils this summer in Rochester Minnesota at Quarry Hill nature center. I'm wondering if anyone regonises some of them. They are all Ordovician in age. 1. Unknown 2. Trilobite? 3. Trilobite? 4. Trilobite for sure. Anyone know the genus or family 5. Trilobite? 6. Shell or something else?

During our last warm spell in November ( a high of 40 may not sound warm to you southerners), I took the opportunity to collect a few buckets of Decorah Shale to process during the cold snowy month of December. Here are some of the fossils found. Nothing too exciting, but fun to find!! @Tidgy's Dad, I would be pleased if you could assist me with my attempted IDs!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! And if there are some that you do not have yet, let me know and I will see about sending. 1. I suspect Platystrophia extensa

Here is a rock I found over the summer but I am continuing to clean. With the tools I have and the rock's size it is quite difficult to get dirt out of the small bits but it's looking much better. I found this very early in my fossil collecting hobby so at the time I didn't know much about what it was, but I now know that it's crinoid bits (perfectly obvious to me now of course, but it's part of the experience). One thing that's cool is when I first uncovered it, it looked like the whole one side had the bits, but you can see along the middle there isn't as much debris as the sides, which lead

Tips for Fossil hunting in the St. Louis Area of Missouri
Joseph Fossil posted a topic in General Fossil Discussion
Recently, I've been thinking about conducting an exploratory fossil hunting trip in the St. Louis area of Missouri. I've never been there before, but I've heard there is a lot of caves and limestone outcrops near the city. I've also heard there is a decent amount of Ordovician and Mississippian fossils in the area. I'm just wondering if anyone's been fossil hunting in the St. Louis area before and what fossils can be found there? -
Hello guys, I would like to know your opinion about the ID of the Asaphidae ssp. I have. Thanks in advance for your always precious help. Best wishes, Miguel a) From Zagora

Here's something I've been trying to ID for a while. At first I thought it was a conodont, but all my research has so far indicated that it's too big to be one, and I don't really know what else it could be, or if it's even a fossil at all. Any input is highly appreciated

Ordovician, Nicolet River Formation, Crinoid columnal segments
Denis Arcand posted a gallery image in Members Gallery
From the album: Fossil Art
These crinoid segments look amazing in their natural color -
G'day everyone! I have reccently come back from a three day trip to Forbes with the Australian Fossil Club where we looked for Ordovician and Silurian trilobites. We checked out the Silurian Cotton Hill Quarry as well as some new Ordovician sites around the town of Gunningbland. Fellow forum member @Foozil was also apart of the trip. Over the three days I ended up with many beautiful trilobite fossils and my first whole specimens! @piranha could possibly help with IDs? DAY 1 - Cotton Hill Quarry Friday morning my dad and I left home at 3:30 AM and began the 7 and

I recently got this trilobite and don't know the genus. I think it is from the Order Harpetida. The listing said it is from the El Kisan formation, but I can't find any formation called the El Kisan formation. If that formation doesn't exist I think it's from the Fezouta Formation. It was found in Zagora, Morocco and is Ordovician in age. I haven't seen anything similar and it might be undescribed, but that's just speculation. It is 0.9 cm long.

Here are a few trilobites, damaged and partials that were found this summer. After cleaning these up over the last few days, I still am unsure of their identities. The first one I will venture is an Isotelus roller. Rollers always confuse me! It is from the Maquoketa/Ordovician and Isotelus are common. @Kane, @piranha 3. is also from the Maquoketa/Ordovician. Maybe not enough present to tell. The rest are from the Platteville/ Ordovician. 4. Popped out of the matrix during prep. It measures 2.5cm by 2.0cm. I count 9 thoracic

Earlier this month I spent a day collecting in the Kope Formation (Upper Ordovician) of northern Kentucky. It is one of my favorite formations to hunt, and I always walk away with some nice stuff. Here are some of my better finds. A decent Ectenocrinus. It is crushed but should turn out nicely after prep. A much smaller Ectenocrinus hiding in a hash plate A pretty classic Kope hash plate. There's a cluster of crinoid arms to the left of center - I doubt there is a calyx but we'll see. A very nice Cyclonema

Happy new year! I wanted to show some of the highlights of an unexpected discovery from December 31 last year. I was in my garage when I noticed a pail full of rocks so I decided to try my luck and see what I could find. While I expected to find a crinoid stem at best, about 75% of the rocks ended up having something or another in it! 38 rocks in all ended up being relocated to my room, some have just a few brachiopods or whatever, but some I only have the slightest idea what they are, so any suggestions are much appreciated. Unfortunately I have no idea where any of these came from so there's

A post was made a few weeks ago showing the Decorah Shale finds during my last fossil hunt of the year. During that trip, a section of Stewartville/Galena/Ordovician was visited too and I just finished processing my finds. In the bucket were a few unknowns that I am hoping to make known!!! 1. My guess is likely correct for this one. Beekite? I notice on the picture that that a piece of Isotelus trilobite is peeking out in the lower left corner and is probably the reason for the beekite formation. I have searched through Galena countless times and have not run into this before.

Locally, graptolites are very common in the Maquoketa/ Ordovician rock. They present themselves as 2 dimensional creatures on certain bedding planes. Below the Maquoketa is our Galena. It has graptolites but uncommon. Again, they present themselves as 2 dimensional. The "unknown" specimen from the Galena, presented today, is obviously 3 dimensional and I venture a guess that it is a Graptolite. But I thought I would seek opinions in that I have seen thousands of local graptolites but never one that is 3 dimensional. Could it be something else??

I spent some time today examining this little Triarthrus specimen when I noticed what may be a preserved eye. This one was found in between pieces of shale, so the first 2 pictures are from one side while the last 2 are the other. I've seen other Triarthrus fossils that have eyes in the same place so I do think it may be one. Are trilobite eyes a common part of fossilization?

Hello all. I recently engaged in my first fossil hunting expedition at the Caesar Creek Spillway in the Cincinnati region of Ohio. While most of what I collected I was able to (probably) positively identify as various Ordovician fauna, one specimen has stumped my lay understanding. I believe it to be a partial fossil, about 2.5cm by 1cm, apparently ovular in cross-section with fairly clear segmentation. From some image comparison I've done I was initially leaning towards it being a partial Cephalopod, however what I'm interpreting as a waisted section at one end is throwing me off. I'm no

It was a beautiful, warm (almost 50 degrees!), sunny Halloween day in Minnesota when Kris and I went fossil hunting together. I took her to the BEST gastropod site in Minnesota! She loves the snails too. :-D Age is Ordovician and we were in the Stewartville member of the Galena Formation for both sites collected. Kris at site one pointing to gastropods stuck in the rock. Hormatomas stuck in the rock. We didn't go a 1,000 yards and her pail and my backpack were full of great finds. And I got these pics of those we could not take.

Ordovician Marrellomorph from Ontario
MarcusFossils posted a topic in Partners in Paleontology - Member Contributions to Science
I found this specimen in 2020 and donated it to the Royal Ontario Museum later that year. A paper is to be published very soon formally describing it! It's a roughly 7cm wide mimetasterid marrellomorph - the only marrellomorph know from the Ordovician of Canada, and one of a handful of such arthropods recorded worldwide. I found my very first trilobite in 2014. The members of this forum helped my ID it, learn more about the stratigraphy of my area and what tools to use to find more. Thanks to that base of knowledge,, the last 7 years have seen paleontology become an increas- 10 replies
