Curled Dipleura dekayi sitting on a slab with an enrolled Eldredgeops rana. Apparently, the Eldredgeops was added to this Dipleura to create this "association" piece.

Good evening folks. I am working on curating my middle Devonian collection using the field guide book by K.A. Wilson. It is very helpful and has saved me tons of time, highly recommend. I am posting below a few of the fossils that I could not quite figure out using the book and was hoping for help. A few of these may be unsolved repeats from past posts. I realize this may be a lot so very much appreciated in advance. 1. Locality Livingston County Two pieces of the same broken fossil 2. Deep Springs 3. Deep Springs 4. Deep Springs 5. Deep Springs 6. Erie Co. 7. Penn Dixie 8. Erie Co. 9. Penn Dixie

I have a few shells like the one pictured below from Penn Dixie in New York. All I have for prep are dental picks. Is it possible to clean out the matrix to reveal more of the shell details with basic tools?

Just started searching for fossils since moving to central New York. These are some finds from Madison County. I was hoping for some help, I know they are trilobites, but not the species. There were also some shells I was curious about. Thanks.

I was at Penn Dixie a few weeks ago and had trouble figuring out what a couple of my finds could be. My first thought for this one was a piece of a trilobite, but I’m not 100% sure on that. I don’t know where to start with this one. Any help is greatly appreciated!

Decided to take a trip to Deep Springs Road in hopes of finding a complete Dipleura dekayi fossil. I have only ever explored the Devonian shales of Erie county, so the differences in the fossils was really refreshing. I have put some of my interesting specimens below. Also I did find a few pieces of trash that I picked up. Please help keep the site clean if you visit! Thank you for the help identifying these fossils that are new to me. 1. Found within my first 20 minutes at DSR, I never sniffed Dipleura again the rest of the day! 2. A type of gonatite maybe? 3. Not sure about this one. 4. Another one that is new to me 5. What I think to be great preservation on this bivalve 6. Saw a lot of gastropods, none of this size. I am guessing this is another bivalve.

After dinner I went back to the fossil site in Tully New York. I found one specimen that I am kind of excited about but need your opinion. The specimen definitely contains some pyritized cringed branches. But I think it may contain 2 calyxes as well. I will show you some pics. Pic #1 shows the whole specimen. Pic#2 shows a stem which appears to be connected to the light colored ball in the center of the light colored section of the rock. Pic #3 shows what I think may be a small damaged calyx with atleast one branch coming off. Pic #4 shows another branch and next to it, a small grouping of tiny branches or maybe pinnules. Pic #5 shows a cross- section of pyritized crinoid stem. My question is do you guys think this would be a good candidate for a professional prep? There seems to be a fair amount of stuff showing and there may be more that isn't. Plus everything appears to be pyritized. If there is a calyx there could be more branches attached. This would be a very sweet find for me. I appreciate any feedback. I will post pics of the other stuff later.

The Devonian period is known as "The Age of Fish", but could also be known as "The Age of Brachiopods." In the Early / Lower Devonian, brachiopods reached the height of their diversity towards its end in the Emsian. We see the ancestral groups occurring, lingulids, craniids, orthids, protorthids, pentamerids, rhynchonellids and strophomenids, as well as the later successful groups we have seen before such as atrypids, athyrids and orthotetids, plus the rise of spiriferids, spiriferinids and productids and the beginning of the terebratulids. By the end of the Devonian , several of these groups are extinct or severely reduced in importance and brachiopods never quite recover. Also, the Devonian is the last time we see trilobites with such variation, large sizes and numbers and orthocerids too are much more uncommon after the rise of the goniatites. The massive tabulate coral reefs also disappear after the Devonian. Fascinating period and I hope to share some of its wonders with you. Equally, a lot of this is rather new to me, so I would be very grateful for any assistance, corrections or further information on my specimens. Thank you. The Early Devonian epoch is split into three stages, so let's start with the first of those, the Lochkovian, that began about 419 mya and finished roughly 411 mya. I have been sent a nice selection of brachiopods from the Kalkberg Formation, Helderberg Group by the Mighty @Misha, mostly. But the kind gentleperson also sent me this fascinating little bryozoan hash : It is dominated by fenestellids, which is usually the case in the Devonian, but other orders sill occur. These ones, I think, are Fenestella, but there are so many species in the formation that I wont take a guess as to species : Not sure what this one is ;

With the 3 day weekend, I was finally able to get out for a fossil hunt! I was located mostly around Utica NY. Day 1: I started at the bottom of the ocean with a benthic Triarthus site near Little Falls. After some literally prickly encounters getting down to the river, I pulled the thorns out of myself and had a beautiful little spot! Naturally the in-tact shale was on the opposite bank, so I had a nice cool wade on a hot summers day and thoroughly soaked my boots. The voyage was well worthwhile I’ve never worked with shale this clean before. One piece was 3x3 feet, and with the slightest tap, you could flip through the “pages” like an enormous stone book. to start us off here are some photos of the site and some finds. Help with ID on the algae/sponges accompanying the Triarthus trilo-bits is much appreciated! Any tips on prepping these Triarthus too? The shale is thin and they seem to be mostly upside down.

Hello fellow fossil fanatics, I recently found some great crinoid fossils, and I was wondering if any of you had recommendations regarding how they would be best prepared. Both fossils are in two pieces, and I bought Krazy glue today to fuse the pieces together. Since I have never done this before, is there any particular technique which allows for the best bonding? Should I separate the pieces, apply the glue, then reattach? Or should I try to have the glue seep into the seam between the pieces without separating them? The rocks both seem to be very full of crinoid stems! Do you think I should try to expose more using an air scribe? I would prefer to use an air eraser but my Paasche is so weak, it does nothing to any of the rocks I have used in the past. When prepping, should I try to go around the fossil imprints on the surface? What do you guys think?

Hello. This is my first post to this forum, so sorry if I get something wrong. I found this rock, among others, in Cooperstown, NY in an exposed hillside. I believe it to be a part of the Moscow Formation. I am completely unsure of what this is. I found many other fossils of things like brachiopods, but this is unlike any of them. There are three of these "things" in total, two next to each other and one at the bottom, not completely there. They're each 1.5 centimeters in length. If someone could ID these for me, I would greatly appreciate it.

I recently went to Penn Dixie for the first time and was not disappointed. Our tour guide first showed us the youngest rocks, then the pyrite. Here I found a tiny juvenile Tornoceras, Bactrites, and out guide showed us that individual septum can be found (see this post). I also found a fragment of a non-pyritized tiny Eldredgeops thorax. I found what HynerpetonHunter says is worm coprolites, and a few tiny brachiopods. Then, we went to the place where phosphate can be found. After that, we stayed a little at the place where fossils from the oldest layer were deposited in the soil, and I found a Naticonema gastropod, among the rarest fossils at the site! There were lots of brachiopods, crinoids, and rugose corals here. We then found some more corals, brachiopods, and trilobites at the most recent Dig with the Experts piles that were turned up for collecting. We walked towards the stream and on the other side found many bryozoans and coral (this time Favosites). I dropped my bucket of fossils but was able to find most of its contents again. We went to a place nicknamed "Crinoid Heaven", because of the sheer amount of crinoid columnals that can be found there. after that, we went to the original Dig with the Experts that was unearthed in 1993 (there wasn't much). After this, we went to where some trilobites are, but not as much as the recent Dig with the Experts site, so we went back. By this time our tour was over and we simply filled bucket after bucket of fossils. I found some Bellacartwrightia, Greenops, too many corals, and many, many Eldredgeops. I agree with Clary and Wandersee's (2011) rating of Penn Dixie as the top fossil park in the U.S. Below are some pictures of some of my favorite finds. First, some Eldredgeops. I prepped the top right cephalon with some dental tools. These can be found abundantly, but here are some of my best. ======================================= Some Bellacartwrightia. These are uncommon Asteropygines that are sometimes confused with Greenops. To prove that this cephalon belongs to Bellacartwrightia, look at its cephalon posterior border furrow - it continues down the genal spine, while it ends at the base of Greenops's. Directly above it is a juvenile's pygidium. Some more Bellacartwrightia pygidiums - on the same rock but on different sides. =================================================== A Greenops cephalon - the cephalon posterior border furrow ends at the base of the genal spine and does not deflect backwards. An enrolled Greenops in the matrix. Since Asteropygines have such this cuticles, I am going to wait to prep this one. Note: the scale bar is equivalent to 2 mm, not 1. ============================================= Now for the Gastropod! This is Naticonema, dorsal and ventral. ============================================ Mucrospirifer. ======================================= Placoderm bone? I am not that good with bones and any help would be appreciated on this one. I know more of these have been turning up lately, or at least being recognized. Penn Dixie was certainly worth the long drive and I very highly recommend it!

Earlier in the beginning of the year, I was asked by one of my club members to lead our Syracuse club on a field trip to DSR. The member who asked is a longtime member of the Syracuse club as well as one in Pennsylvania, which is were he resides. The plan was I would lead the Syracuse members and he would bring the Pennsylvania members on the same day. We decided on May 7th. I realize that I am a bit late posting this report, so please forgive me. Been busy. It turned out to be a great day weather wise. I brought my youngest son Devin, even though his plan was to look for snakes. We met the local members at our clubhouse at 8 am and arrived first to the quarry about 9:30. The PA. Group showed up a bit later. Forum member @Al Tahan showed up with his cousin and her daughter. In all there was around 20 fossilhunters. From here I will let the pictures do the talking.

Hi everyone! I just got back from a trip to Penn Dixie Fossil Park near Buffalo, New York, and found some pyritized cephalopod fossils. Penn Dixie has rocks form the Givetian of the Devonian from the Hamilton Group. A young ammonoid is easily identified as Tornoceras uniangulare, but the other orthoconic fossils are harder to ID. I am pretty sure the small but more complete one is a Bactrites, because the siphuncle appears to be almost ventral, the distance between the septa, and the slightly slanted suture (after looking at Ludwigia's). The preserved shell is very smooth and couldn't be from a Spyroceras that are also found at Penn Dixie. Similar fossils to mine are pictured on their website, unidentified. If any more pictures are needed, I will try to take them. I wanted some expert advice before concluding it is a Bactrites. Can anyone help?
