Army of trilobites - found in summer/autumn 2018 and preped during autumn 2018. 2 different sites, 3 visits in each. -
I recently found an exposure of the Ordovician Catheys formation in eastern Williamson County, TN. The exposure of blue-grey shaly limestone seems to match well with the trilobite rich facies described by Bassler in the Franklin, TN area. I did not get to hunt it very long, but saw lots of fossils and several trilobite fragments. In addition to many fragments of Isotelus, I found several fragments of lichid trilobites. Bassler referred to these as Platylichas sp. There is a lichid described from the somewhat younger Leipers formation, which Bassler referred to as Amphilichas halli (now considered Alolichas halli). He may have just used names from prior work, but he also may have seen some differences. These are definitely from the Catheys and not the Leipers, which is absent over the center of the Nashville dome. I do intend to go back soon and look for more, maybe even finding the elusive articulated specimen. I'm curious what distinguishes Alolichas from Platylichas, and what should I call these other than unknown lichid? Thanks.

Hello, friends! Not too much to go on, so I'm not expecting a definite id, really, but if anyone does have any guesses, I'd be really grateful. I received this as part of a gift and it was simply labelled "Trilobite - Nevada". The only other information the sender could tell me was that it had been found by someone else in "a canyon", not much help. I can tell you that the trilobite is 3 cm long (what's left of it) and is preserved in a soft, very thinly layered pale grey shale. It's probably going to be Lower to Middle Cambrian, maybe an olenellid? Any help would be most appreciated. Thank you! Cheers, Adam @piranha

I found these items while working through the calcareous shale my wife and I collected from Paulding Ohio this summer. This material is primarily from the Devonian aged Silica Shale. I found one and didn't think too much about it, a fragment of fish/trilobite/shell or something else perhaps. Then I found a second which looked similar and so I did some prep and was able to expose more of each piece. These are small (those are mm's on the scale) with the biggest one being about 10mm by 12mm and the smaller one a little over half that size. They don't look like anything I'm familiar with nor could I find any matches in numerous books or online sites. I know the pictures are not ideal and they are embedded in the rock, so nothing from the side or underneath (first two pictures are the same one). They are very dark in color like much of the trilobite material. Oh snarge, it just dawned on me. Are these hypostomes? I don't think I have ever seen one before. Maybe I answered my own question, but I typed all this already so I'm going to post it just to make sure. Thanks, any ideas would be appreciated. Now I see a thread from 2011, so yes, these are hypostomes, but I'm uncertain on which species it is from. Looking for examples from Eldredgeops and Pseudodechenella since those seem to be the genera present in the Silica.

These are a few other fossis I have found in the past .I have collected fossils here for nearly 40 years but most of them have been given away or donated to a local museum here in Birmingham . The sharks teeth are Cretaceous form the Mooresville chalk formation . The Echinoid was found at St.Stephens Quarry years ago in the Yazoo Clay . The little Trilobite came from a site near Russelville in the Tuscumbia Formation . I have found fossils all over , these are the ones that are most convenient to photograph at this time . The arrowhead was found in a creek while collecting fossils .

Hey Everyone I am new to the Fossil Forum but not new to fossil hunting! I am looking to connect with some fossil hunters form the Northeast US to get into some hunting in 2019. I went to school in Buffalo, NY for Geology and Earth Science back in 2009-2014. I have loved fossils my whole life so it was a perfect place to soak in everything fossils. Lets just say I did a TON of fossil hunting over a 5-6 year period and got decent at it :). I was able to learn a lot from Dr. Richard Batt who did tons of research on the Buffalo geology. Long story short....I ended up joining my long standing family business and I do not have something to satisfy the Geology and Fossil itch. Anyway....to the topic... Pseudodechenella rowi This is probably my most rare and prized trilobite but I do have others that are my favorite for other reasons lol. If you are familiar with the book "Geology of 18 Mile Creek" by Grabau it has a nice layout of what you can find in the Wanakah shale of the Hamilton group. In it is this trilobite.....but it was called Basidechenella rowi (bad habit I still call it that cause of the book lol).......it was a great look trilobite but was NO WHERE TO BE FOUND. No pieces....nothing...ever. I wanted to find it BAD but all i ever found was a Pygidium at 18 mile creek. Until I diversified my hunting locations......I starting hunting at the Type Locality for the Wanakah Shale for trilobites after a tip on its location from Dr. Batt. Some pygdidiums showed up once in a While but even those were rare. Then a stretch of beach 50-100 yards wide started being the only place I noticed they kept showing up. Then one day me and 2 friends found a patch of 6!! After that day I have seen 3 more completes come from the same area.....never found a single piece outside of that spot on a spot really. My last fossil trip was there in 2016 and I went to that strip and found a baby rowi complete and an eldredgeops complete. My friend also found a complete rowi that day but it needs prepping. I am going to attach my best 2 rowis (1 could use a touch up with an airbrush and it would be amazing!!), then a pic of all my rowis I've ever found (I don't know where any of my single pygidiums are). I think I may do a post with my Best Greenops and best Eldredegeops trilobites too if people are interested. I can also post some other Buffalo fossils if there is something someone wants to see. Also.....I have a friend with a complete rowi almost that is 80% covered with limestone and I do not feel comfortable prepping her fossil. If anyone is interested in working on it/giving me a quote or idea what it could cost please let me know. Its an amazing fossil...found but still hidden. Thank you for reading!! Looking to make fossil friends and plan Fossil hunting trips! Al

Hey guys I am curious if any of these are trilobite fragments. They are all very small and thin. Found in Ordovician rocks in Cincinnati. A piece was broken off because of too much water pressure so I outlined what it was like before. It is more brown colored. This piece is a pit more brown colored.

I have a mostly complete trilobite that I found this summer at Paulding, Ohio (SIlica Fm, Devonian) which I had assumed was a Pseudodechenella lucasensis, partly because it looks like one and that was the only species of Pseudodechenella that I was familiar with from the Silica (granted, I'm no expert, I've just done some reading). But in looking at this specimen a bit closer and reading a few of the articles, particularly Stumm's 1965 description of the species, I'm having some doubt on the ID and want to solicit the opinion of the Forum. I know there are several Devonian trilobite enthusiasts out there and I would appreciate your thoughts. The primary feature that has me questioning the ID is the lack of a medial groove on the brim of the cephalon which according to Stumm is supposed to be one of the diagnostic features. I don't see one on this specimen, but could that be a matter of preservation, growth stage, or just variability within the species? I have seen that P. alpenensis is also found in the Silica Fm. but that appears to have a much wider brim that what this specimen has (about 1mm wide). There are plenty of other species of Pseudodechenella from other areas of the same age and I have looked at lots of pictures, but not picked an obvious match. Stumm made a comparison to P. rowi, but I am not aware of this species being found in the Silica Fm. I am working on gathering the descriptions of these various species so I can see if that helps me, but I thought I'd see what some of you thought. Any ideas are welcome, thanks. The scale is mm's, it is about 19mm long.

Bought this a year ago. Assumed the little bit of detail in the eyes meant it was authentic, but I'm not sure anymore. Seems like the spines are fabricated at the very least. Would love opinions since I'm still pretty green.

Newbe looking for kid-friendly fossil hunting sites near Boston
EllaS posted a topic in Fossil Hunting Trips
Hi all I'm an old-time fossil fan new to the US. I've had my share of luck hunting fossils in Israel (ammonites, shells etc), and am now based in Boston with kids who have a good eye and need to learn to search. Can anyone recommend a good, legal fossil hunting site in the area (up to ~2 hour ride)? I'd be most keen for trilobites, since there are none to be found in Israel, but would welcome anything that's kid-friendly (i.e. strolling/sifting rather than shale digging). Thanks! Ella -
Found these rolled fossils in the Decorah Shale, St. Paul, MN. Tan colored and measures 2.0 cm long by 1.2 cm wide. The broken piece looks to have piece of Trilobite with it. Thanks for your help.

Dear TFF, This trilobite ( max. 36 mm) is probably from Erfoud area, Morocco. I believe it will be recognisedby our Trilobita experts. Thank you very much.

A few french trilos preped during the summer 2018
elcoincoin posted a topic in General Fossil Discussion
During the summer i found time to empty a bit crates from the recent trilo hunts. Here come some of those recent prep. The samples come from 2 different sites which are only a few kilometers away one from the other. More or less orange ones from one place, black ones from the other. To start with, the emblematic Neseuretus tristani, most common trilos in our area. Those are second grade samples, but still, here they are : -
I finally managed to get my cheapo air abrader working today so I want to show off my first self-prepared trilo. Eldredgeops rana found a few weeks ago at penn dixie fossil park in NY Before starting only the right eye and a few segments were exposed (forgot to take a pic before starting...) so I assumed it was a roller of some sort like most of the others I've found. The exposed section also had compression damage so it seemed like good practice material. Luckily I didn't destroy it because aside from the compression it turned out to be a very well preserved prone! The air abrasion was done using a paasche air eraser at 50 psi with dolomite. Everything so far was done without magnification so I need to finish off the eyes and some of the deeper crevices under a scope.

Giant Trilobite - How much Restoration?
MarcusFossils posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi all, I was hoping for a few opinions regarding the percentage of restoration on this 35cm+ Acadoparadoxides sp. If anyone can narrow down the species, that too would be appreciated. Thanks! Positive side:

I was driving between Claremore, OK and Collinsville today and stopped by an old road cut. We have had some heavy rain and thought I’d check. I found this little piece and got excited thinking if may be a rolled up trilobite. If it is it will be the first I have actually found myself.

I am down to my last few trilobites to label from this summer yet. Am open to suggestions on these less than perfect finds: 1. Found in the Galena/ Ordovician of Iowa. Isotelus? If so, is the species obvious? 2. Found in the Platteville formation/ Ordovician of SW Wisconsin. Flexi? 3. Another Galena/ Ordovician but from Minnesota

The Middle Devonian fossils of New York State are well known and have been for over 100 years. I grew up in Livingston County in whats called the Genesee River Valley. The streams that feed this river within the county are rich in Devonian fossils. I collect fossil corals, brachiopods, bryozoans, crinoids&blastoids, pelecypods, gastropods, cephalopods, phyllocarids, trilobites, fish, and wood. I rearranged my favorites in my collection and thought I would share since I feel the display will remain like this for some time. Out of the thousands of Middle Devonian fossils I have collected in 30+ years, these are the ones that mean the most to me. Thanks, Mikeymig

Looking for unprepped or lightly prepped drotops or other big Moroccan trilobites
mattbsharks posted a topic in Member-to-Member Fossil Trades
I am looking for hopefully complete or near complete drotops, and other large Moroccan trilobites. In exchange I have lots of stuff, shark teeth from all over, ammonites from Europe etc. please message me if you’re interested -
I don't know whether to laugh or cry on this one. Found an enrolled Trilobite in my micro matrix. Gave it a nice spa treatment of hydrogen peroxide & got most of the matrix off. And then took a look at it with my dino lite & found that it has almost no head. Thing is maybe 3.5 mm across and the one thing I didn't actually expect to find. No idea if it can even be identified now, but here's the pics anyway. Pics are 45 x magnification. Jasper Creek Formation. Late Pennsylvanian.

A few things from the Silurian (Llandovery) Cotton Formation near Forbes, NSW Australia. Most of these specimens are currently undescribed, but a paper will be released on them soon. One of my strophomenid brachiopods from the site will be in the paper, so I'll post it when it comes out, since they're a pain to photograph. The rare Aulacopleura pogsoni ....
