Hope you can help with this one, found in the malahide formation Carboniferous limestone dublin east coast ireland

It was purchased three years ago. Place of discovery Krasnoyarsk region

Hi guys found this in the malahide formation in dublin ireland in carboniferous limestone, it took a while to prep

Possible Diplopoda-3.tiffHello all, I’m hoping someone could lend their eyes and give their opinion on something I found. This is from a small rock I found near the Narragansett Basin area of Rhode Island. I recovered it from an undeveloped plot of commercial land that is sometimes used as a construction fill dump, so I don’t know where it originally came from. It appears to have a symmetrical pattern, but I could be seeing what I want to see. Rhode Island fossils are from the Pennsylvanian Period (mostly ferns, horsetails, some trilobites and occasional insects). If anyone could shed some light on this I’d be very appreciative!

Hi guys found this on the malahide formation close to dublin ireland

Identification help requested! In presumable Burlington chert (Mississippian: Tournaisian/Osagean) of east-central Missouri (Lincoln County), USA, I recently came across a mostly moldic chert specimen of what must be a bryozoan, but I do not know what early Mississippian bryozoan would possess such a robust axis devoid of zoœcia, as in the later Mississippian Lyropora. At first I was not even sure it was the bryozoan’s own axis but instead thought the bryozoan was somehow associated with an orthoconic cephalopod. Each photo below is paired with its optical inversion to help visualize what originally filled the mold. Scales in mm. The main reason I feel confident that this whole structure is bryozoan is thanks to a colleague’s find of a presumably related unidentified bryozoan, also in moldic chert presumably from the Burlington Formation but from southwest Missouri, that shows the axis and its texture much more clearly than mine. Here is that specimen, again with inversions. Again I have no knowledge of an early Mississippian bryozoan built like this. (Yes, the axis surface texture looks quite a bit like the texture along the genal rim of some Mississippian trilobites! But it also resembles undoubted bryozoan textures I’ve seen.) Identification help requested! Thanks.

Another new one for me, hope you can help

Gonatite or gastropod guys

Last week on Fossil Friday, the Museum of Natural History and Planetarium in Roger Williams Park added the fossil I found from my post last time and still proud about it because they said on their Facebook page that its only one they have in the collection . Because its the first of its kind I discovered around New England until I find more fossils around that site in North Atteborough just waiting to be discovered with a story to tell.

I hope this is a trilobite, my first irish one

Hi guys curious abut shell id and also the net like main patern, hope you can shed some light

Hello all! I just recently purchased this specimen which was indicated to be from the Carboniferous, Bashkirian-Westphalian B, beds of Poland, dated to be Pennsylvanian at 314 mya. It was sold to me as a Trigonotarbid abdomen. The white square is 1 x 1 cm for scale. While I am no expert on arachnid orders, it appears to be lacking the segmented plates that surround the perimeter of the inner abdomen. Could this be part of some other segmented terrestrial arthropod, or could this feature be covered up by surrounded rock or have been damaged? I will be posting pictures of the specimen below, please let me know if you have any questions or need further information to support a conclusive ID. Excited to hear y'alls input!

This are two carboniferous fossils from Arlanza, Spain. The first one is a Pecopteris and the second one is a tree trunk if I am not mistaken. Do you have a different opinion or have a more specific ID? The Pecopteris The tree trunk

Spiriferid brachiopod guys?

Guys is this a bivalve stuck in the back? Im guessing the main one is a straight shelled nautiloid

What could this be guys, not finished polishing but very curious

It'd been awhile since I last joined the Austin Paleo group for one of their field trips, so I was excited to finally catch back up with them at some sites about 3 hrs up north. The plan for the day was to hit up Brady and Santa Anna, but the weather forecast had put things into question. Originally, I had some rather ambitious sites lined up in the Llano Uplift afterwards. The rainy conditions, however, meant the river would be a little too high for walking. After a peaceful morning drive under the guiding light of the full moon, I pulled up to the first location where I was relieved to see things weren't canceled, and Melvin plus the gang were already crawling along the slick exposure of Strawn Group shales (Desmoinesian Series). Upon stepping out of the car, I was suddenly met with a confusing mix of cold drizzly rain and warm gusts of humid wind. It wasn't unbearable though, and I was more so focused on catching up with some familiar faces anyways. The hunting proved a bit treacherous. The ground shimmered with newly formed mud mounds that loved to stick under your shoes. Although it wasn't nearly as bad as wet Grayson/Del Rio matrix (Waco Pit), it was still a strenuous activity, having to climb the hillside in my new platform shoes. Things started off a bit slow. The weather dampened the mood, but with enough effort, people started making some decent finds. I was hopeful to prove my crinoid crown from last year was no fluke, so I went straight to business, closely inspecting every rock for anything out of place. It was a challenge to look for details through the mud. Nevertheless, it was a rich site and everyone kinda knew the spectacular finds would roll out one way or another. After an hour and a half of looking at hash plates and broken brachiopods, I found the first keeper. Especially since it was covered in mud, this guy was tough one to notice. I think 9 times out of 10 I would have walked over it. A small, smashed crinoid crown and arms Nearby I also picked up a small crinoid cup which are always fun to find. As we were wrapping up, I took a gamble wiggling out a mucky mass of what looking like a crinoid arm erupting just from underneath a bigger rock. It didn't take long to figure out it was most definitely a large crinoid crown. The species is hard for me to say, so I am open for suggestion. A large crinoid that took a bit of cleaning. The other side shows some arms, but there is a lot more matrix covering it. With all the rain, Melvin and Ed decided it was wise to skip what would have been a messy parking situation at Santa Anna in favor of an impromptu trip to the beloved Wilson Clay Pit of the Harpersville Fm (Virgilian Series). After about an hour of caravaning northbound, everyone gingerly parked their cars along the gravel margin. It took a bit of teamwork to set up some big rocks for a makeshift bridge across the mote separating us from the gate, but we pulled through. Others gave up a bit too early and decided wet feet for the rest of the day would not dissuade them from taking the shortest route across the puddle . Wilson was a good call as things were surprisingly easy to traverse once inside the quarry. All the rock fragments made for good footing. I had made a couple new friends who happened to be fossil forum lurkers. One of them was named Will, and I decided to help him out with finding some Pennsylvanian shark teeth. Once we located the right rocks, I tried to show him what to keep an eye out for. He was a fast learner and pretty soon we were both consistently spotting little pieces of Petalodus among other cartilaginous vertebrates. Sadly, I didn't find most of my cooler stuff until he was sick of all the hammering and ventured elsewhere to find inverts! The first keeper for me was a mess of associated Archaeocidaris plates and spines. Not nearly as pretty as those of the Brownwood Spillway, but still neat nonetheless. Archaeocidarid plates and spines Not long after, I made a rather unexpected discovery. I guess in the past I wasn't looking at each rock close enough. I had heard of Cladodont sharks being found in Wilson before, but never saw one myself. Over the course of the day, however, I found like 6 of them in varying condition. They are surprisingly common, but go unnoticed because they are usually so tiny. I have seen the species Symmorium reniforeme referenced in Wilson, but I am under the impression that these teeth are now classified as Glikmanius occidentalis. My favorite is the middle one below. Its white coloration makes it almost look like a modern shark tooth on the beach. Cladodont (Glikmanius occidentalis?) shark teeth. Surprisingly common in smaller sizes. "Deltodus" was the second most common shark of the day and I managed to snag one in near perfect condition. "Deltodus" Throughout the day I was really hoping to find a Petalodus as good as the one from last year, but alas it was not meant to be. Still, there were some decent ones that showed themselves now and again. One tooth has some really cool dendritic mineralization on the enamel. Best Petalodus ohioensis of the day. As I was writing the above excerpt on the dendritic Petalodus, I took a second look at it and just noticed a trilobutt on the back of the broken root! First Wilson trilo for me and it's on a Petalodus tooth go figure. I guess there's no other way I'd find one given my vertebrate fixations Trilobutt on Petalodus! It was about sunset when I left. Of course I was one of the last ones there along with Ed and Melvin. I need to work on my controlling my fossil hunting urges for sure. Anyways, it was a nice day for a hunt and definitely something I needed. The 3 hour drive back felt like nothing as all I could think about was what awaited me the next trip out. Thanks for reading!
