This weekend we're taking a long weekend up to the Niagara Falls NY area. We're going to be doing the typical tourist stops plus a visit to Penn Dixie. . Based on the weather forecast I would assume to be there at opening time to avoid the afternoon heat and possibility of thunderstorms. I don't know yet if we're going to be there on Saturday or Sunday. Is there any tips or suggestions for first timers to Penn Dixie? We have a rock hammer, mason's hammer, an engineer hammer and several cold chisels. Also on a totally unrelated note any restaurants in the Buffalo/Niagara Falls area that anyone would recommend for the family. Thanks for any information and I will post a field report early next week.

As before, hopefully one of the trilobite experts can identify this specimen. This is another unidentified trilobites I collected from the Ordovician Liberty Hall Formation near Blacksburg, VA many years ago. It is 7/8 inches long. I've been collecting at that site for since the mid 1980's off and on and this is the only specimen of this trilobite I've found. Let me know what you think. Thanks

As before, hopefully one of the trilobite experts can identify this specimen. This is another unidentified trilobites I collected from the Ordovician Liberty Hall Formation near Blacksburg, VA many years ago. It is 2 1/2 inches long. Since I've been cateloguing my collection, I'm also trying to get some of the unknowns identified. Not sure whether to go Flexi or Gravi. Let me know what you think. Thanks

Hopefully one of the trilobite experts can identify this specimen. Here is one of a couple of unidentified trilobites I collected from the Ordovician Liberty Hall Formation near Blacksburg, VA many years ago. It is 3 inches long and is the negative. It looks to have 10 segments. Since I've been cateloguing my collection, I'm also trying to get some of the unknowns identified. I'll be sending a couple others out to you guys. Thanks

I've been racking my brain trying to identify these trilobite pygidium. Its my understanding that these all came from a quarry in the Bardstown KY, USA area. Its also my understanding that the site has New Albany Shale and Beechwood Limestone which are members of the Sellersburg Limestone Formation and is Devonian in age. These don't look like anything that I know of that has been found in the area/age of rock. To me they look more like Griffithides Bufo , but that trilobite is found in Mississippian age rock. Any input would be welcome! Far Left: Middle: Far Right:

As usual I had the urge to go fossil hunting this weekend so I decided to take a trip to Arkona and have a relaxing day of surface collecting. It was calling for rain all week but turned out to be a nice day (aside from the brutal heat and swarming deer flies). Things were looking a little different this year. Spring hit this roadway to one of the pits pretty hard. Critters everywhere so you have to watch your step. There were loads of tiny toads that must have just grown up and left the water. Also found this poor strawberry plant struggling on top of a hill in poor soil but somehow managed to fruit And now for the fossils... I didn't have any luck finding the blastoid or crinoid I was after but I did take a few things home. Some corals Aulocystis ramosa, Platyaxum frondosum Favosites sp. A brach species I didnt have yet and a large Callipleura Nucleospira concinna, Callipleura nobilis An interesting bryozoan and a cluster of tube worms unknown bryozoan, Spirorbis sp. Gastropods Platyceras bucculentum, Naticonema lineata Possible arthropod trackway? And a new trilo species for me. Beaten up but I'll take it. The cephalon+partial thorax look like Basidechenella Pseudodechenella arkonensis. The pygidium looks like Crassiproetus crassimarginatus (top one was found last year).

It has become a yearly tradition of mine to visit the upper part of Michigan's lower peninsula, around the Gaylord and Traverse Bay areas, for vacation with my family, and I often spend time looking for fossil in the area, mainly Hexagonaria/Petoskey stones, but for some reason they are far and few between. During my time in the area, I have also found a chunk of limestone containing what appears to be the glabella of a trilobite surrounded by what appears to be large, crystalized corals, possibly a Heliophyllum or similar rugose coral, a smaller piece of the same coral, and what seems to be the calyx and arms of a crinoid. Should I be looking anywhere in particular along the shores of Lake Michigan that aren't as well known as some of the popular tourist destinations? Also, are there any areas more inland that are accessible? (i.e. old quarries, roadcuts, etc.) Any and all advice would be greatly appreciated!

It's taken me a while to post this, but my boyfriend and I took another trip to Penn Dixie on the Fourth of July! For those who have been to Penn Dixie I'm sure you know it's impossible even for a total newbie to leave empty handed. I didn't get anything super amazing like some of the full trilos th at I've seen other people post, but I did get what I went in hoping to find - gastropods!!! I THOUGHT that I found 2 - the large one and the good spiral one. But when I started washing the mud off them last night I discovered two others on the other side of some chunks that we had kept for their trilo fragments! They aren't perfect, but I'm so happy because all I've wanted to find since I started going to Penn Dixie was a snail It has a little bit to do with my love for David Attenborough shows and learning that we are currently in the Golden Age of the Snail which makes me unreasonably happy. I'll try to get some more pictures tonight of everything we found to help illustrate how many fossils you can leave Penn Dixie with - even when your boyfriend is making you be more selective and says you can't keep everything! I took a picture right after I found the third gastropod (the smaller not spirally one - I know the name is in the Penn Dixie guidebook but I can't think of it right now) Realized I jumped the gun by taking a picture of the three when I found this guy! He's definitely not as great as the other spirally one, but I might try to extract him better at some point! Not even the best trilobite pieces we found, but the only ones I have pictures of at the moment!

Hi there, guys. So, I recently bought a lot of trilobites from a Morrocan seller. I asked here in the forum for an ID and it turned out one of the trilobites came with wrong determination, so I'm adding pictures of the other specimens hoping you guys can help me get to genus at least. They were all sold as Phacops, but of course, the seller does not have knowledge enough to ID them, and neither do I (probably, even less, actually...). I'll add the pictures below for each specimen. First two pieces I believe it's Flexicalymene sp. Thanks in advance, Juliano

I found this small pygidium while prepping some Penn Dixie material. Not sure whether it’s Greenops or Bellacartwrightia. Any thoughts? @Fossil-Hound @DevonianDigger Hope you don’t mind the tags.

Hi there folks, So, I bought this trilobite from a Morrocan seller and I would like to know the species if possible. It came tagged as Phacops redops, but I couldn't find much information on this species. Is it correct? Found in Atchana Issimour, Morroco.

Had a great 5 days at Penndixie digging found some awesome stuff

I found some unusual structures under the exoskeleton of this Greenops (Middle Devonian) They are auburn brown and somewhat translucent, reminiscent of the material that makes up the exoskeleton of the adult. I only found them concentrated in the area where the exoskeleton of the trilobite came free of the matrix. They are embedded in the matrix there. I did not find any outside of this area in the surrounding matrix. There are a total of 6 of them that are exposed. They are not ostracods. They could be spores, I guess. They could be lots of things, and their concentration within the trilobite could be entirely coincidental. But, Looooooong shot... could they be trilobite larvae? @piranha Below: General location of the objects. Scale in mm. Below: Several of the objects exposed in different positions. Scale in mm (the objects are about 0.25 mm in diameter). This is the best I can do with a dissecting scope. Only other option, if warranted, is SEM (which I can do if necessary).

Here we have a photo of a hash plate which has bits of bryozoa and crinoid ossicles, but is that a trilobite genal spine? The rock is Upper Ordovician Kope Formation or Fairview Formation. Economy, Southgate, McMicken, Mt.Hope or Fairmount members/formations if you like. Lawrenceburg Road cut, Indiana. Thanks all for looking.

Fake Dicranurus Monstrosus Trilobite?
Votex posted a topic in Is It Real? How to Recognize Fossil Fabrications
I am pretty sure that this is a fake but mind if I get some opinions? Thanks! Here’s some pictures. https://imgur.com/gallery/GipDlU3 https://imgur.com/gallery/Ua7bFVV https://imgur.com/gallery/6X5VBVH

Ordovician Stewartville member of the Galena Formation Southeast Minnesota Pygidium I'm thinking... Sorry, best pics I could get. Ceph or enrolled? Looks like trilo eyes staring at me, but what do you think? This is wet to see it better. The dry pics just didn't turn out at all. The "eyes" seem white to me and are raised. Thoughts??? Thanks for looking! :-D

Rediscovering New York: Trenton group and Pulaski Formation
Al Tahan posted a topic in Fossil Hunting Trips
Hello fossil folks Just another one of those “Rediscovering New York” posts. This Edition will include my efforts looking for the Trenton group and exploring the Pulaski formation. More Ordovician exploration in the central New York area. This past Saturday me and my good friend Matt did some trout fishing in the Rome area and another town north of Rome. I had scouted these spots for 2 reasons.....trout and trilobites! One location seemed to have Trenton group exposures and another I had already confirmed as the Pulaski formation but wanted to explore it more. Both were located on stretches of the Mohawk River and anyone can go fish/hike these waters. I learned of another Trenton group exposure with trilobites but it’s posted trespassing. Eventually Ill get the courage to do some door knocking in the area to try and find the owners. I guess I don’t know what I would say lol. I wasn’t really in the mood for that so I went to legal stretches of the Mohawk River for this adventure. The goal: 1. Find Trenton group exposures 2. Confirm trilobites from the Pulaski formation 3. Catch trout!!! More to follow....- 27 replies

On Sunday, I saw this trilobite just sitting there on the face of a cliff. Unfortunately part of this "roller" is missing. I do not do well with IDing rollers so am asking for help!! My guess is Anataphrus vigilans but the specimens I have found have been in the Maquoketa.

Hello, While nowhere close to Kane’s prodigious talent, I decided to experiment today on pen and ink drawing a trilobite, e kingii to be exact. It took around 2 1/2 hours and for a first try I have to say I’m happy with the picture. First fully detailed pen and ink drawing and what better to draw than a trilobite! Thanks for looking, FA

We are just back from a delightful fossiling experience in Utah and Colorado. I want to share just one find now, an Elrathia Kingi from the U-Dig site outside of Delta. There are great descriptions of the quarry in other posts, with directions. I have been here before and always had a satisfying experience. The arrangement this year is that you can either locate yourself someplace in the quarry and break piles of shale the U-Dig folks have conveniently collected for you, or you can break shale out of the quarry yourself and then further split it to see what it might hold. You can break a lot of shale with modest success, so you have to be patient. But if you hit a productive layer it pays off. This is the largest trilobite I’ve found there, or for that matter, the largest I’ve found anywhere. The photo is of the quarry so you can get an idea of the terrain. And the views from the quarry down to the flats are dramatic. Going out there on the BLM road off Rt 50, I saw no sign to the New Dig site, another pay to dig site, which might be further up the road. U-Dig is open without reservation required whereas all the New Dig signs we saw in Delta said you needed a reservation. This is a great family activity and both days we were there this month had lots of kids enjoying the experience. It is big enough that no one need get in anyone else’s way.

Selenopeltis buchii Trilobite?
JillMN posted a topic in Is It Real? How to Recognize Fossil Fabrications
I am aware that Selenopeltis buchii Trilobites from Morocco are very often fake. Anyone have insight to this piece? The plants around it are also a mystery to me. Thoughts?
