Today, I went on a quick early morning fossilhunt. I have been anxious to get out hunting, any chance I can considering how mild winter has been so far. I decided it would be best to start today with little, to no expectations and just see what the day would bring. At about 3:30am I woke up to use the bathroom and when I played back down all I could do was toss and turn. So I did that until about 5:15 and I finally got up. Got to the hunting grounds about 7am, just as the sun was making it's presence known. Unfortunately it was only 20° at the site. There was some snow covering the site as well as ice. Obviously this made digging and splitting slabs a real chore. So much so the there wasn't a whole lot I could do. I was hoping that with the sun out maybe it would eventually warm things up enough to make digging a little easier. So for the first 2 hours i kinda putzed around surface scanning and flipping slabs over, looking for something worthwhile. Eventually I started trying to remove slabs. I was actually starting to make a bit of progress, but then the ground got hard again. While trying to remove the slabs, I picked up a small chunk of matrix that fell off. As I inspected the piece carefully I noticed a small Dipluera pygidium and partial thorax exposed on the very edge of the break. I could tell that the rest of it was underneath some matrix. I would of normally been static but the area where the Dipleura was sitting was pretty fractured and I didn't really think I was going to be able to extract it without the whole thing crumbling apart. But I put it in the truck and decided to give it a shot when I got back home. Other then that I only brought home a bivalve and a brachiopod. There really wasn't anything else worth keeping. When I got home I inspected the trilo very carefully and looked at every fracture going around it, I started breaking off small bits of matrix till it got to the point where all that was left was the portion covering the front half of the trilo. I took my angle grinder and made a notch. Then I took a screwdriver, twisted and popped off the top! That is when I got very excited! Now I have found Dipleuras smaller then this one, but this is the smallest one the I have found in this good of condition. It measures at 1 7/16 of an inch. Totally made the trip worth it! Here is before and after pics.

Possible Pyritized Crinoid Found, Hamilton Group, NY
Rock-Guy-17 posted a topic in Fossil Hunting Trips
Busy weekend with a fossil forum meetup at DSR in Madison County, NY and a Buffalo Geological Society trip to the LaFarge Lockport Quarry which is in the Lockport Dolomite. Very fun meetups with both groups and plenty of great finds to go around. I got pretty lucky with the fossils I found at DSR, including what I believe to be a very small pyritized complete crinoid but I could be wrong. I'll add the suspected crinoid pictures to a separate comment, looking for input from community members. I'll start out of order with Lockport since I did not find many fossils. Just a few nice corals, not sure what the ID would be for these yet. 1. Tabulate coral in matrix, no scale. This was approximately 4-6 inches in length. 2. Two different coral specimens I was able to take home Fossils from DSR: 3. Disarticulated Dipleura trilobite. One of my favorites 4. Tornoceras cephalopod fossil. 5. Paleozygopleura encrusted by bryozoa, great preservation 6. A few of the Greenops trilobites I found, some may be complete under the matrix. Meant to put these in a separate comment, but they are here now. A few too many pictures, but the different saturation and lighting helps view the fossil better. This would be my first complete crinoid, very excited about this one if it is. The larger chunk of shale that I found this piece in had other crinoid partials in it as well.- 15 replies

Since we both had the day off, my daughter and I spent a couple of hours at the Deer Lake site (Schuylkill County PA). It was a beautiful sunny day in the mid 50s! A good start to this years fossiling adventures...

I’ve spent about a year now combing through PA’s Mahatango, attempting to collect all of the trilobite fauna present in the formation. At this point I have all but one, Odontocephalus being the only that’s eluded me thus far. A big thanks to @Dean Ruocco for showing me around and in general refining my craft man. IMG_0717.MOV

Dipleura dekayii Mahatango shale, Danville Pa -
Hey all, I am looking to add two new species to my collection. I would like a Dipleura and an Isotelus. Also interested in most any Asaphida species. Preferably complete / relatively complete (Rollers are fine) Please DM me photos if you have any you are okay to part with and we can make a trade.

From the album: Nautiloid’s Trilobite Collection
This is a pretty okay specimen of Dipleura dekayi. It’s missing the pygidium and the body is a little disarticulated. Collected August 19, 2022© Owen Yonkin 2022

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.

Went on a little "Easter Egg Hunt" with my folks, found some excellent fossils. day was hot but I enjoyed it. I have provided my best ID, but please feel free to correct if you can identify it further! it helps with my labeling system for sure. this lizard was good luck right next to where my mom was standing i noticed this beauty sticking out of the rock further excavation revealed this possible horn coral? eldredgeops rana heads trilobite glabellar fold ( possibly Odontocephalus?) Dipleura rib impression (Very exciting to have found 3 species in one trip!) amonoid Cephalopod Agoniatites vaxunemi (note the preservation of the sutre lines). and here is a conularid i found as well Possible pelecypod? brachiopods and lastly a couple of crinoid buttons dug out of the rock

Hello again everyone, sorry for the delay between Part 1 and Part 2. I went through some more material from DSR and I've made some pretty awesome finds. I might have enough specimens for a Part 3, but I still have to go through more material. The same goes for the Penn Dixie part, I've barely touched it yet and still need to photograph the finds. To kick Part 2 off, here is my best DSR find yet! A nearly complete (unfortunately disarticulated) Echinocaris punctata!!! My kitten Indy for scale The Echinocaris has one of the spikes on its tail visible, and both valves are present. Another Phyllocarid, a Rhinocaris columbina! The reverse side shows another half, possibly from the same Rhinocaris? This cute little cephalon is one of my first Eldredgeops finds at DSR. Here's the Dipleura heads I've found so far (excluding the one from the previous trip report), This one is one of the largest I've found yet, it's 3 inches wide! This cephalon was a real heartbreaker. The other half of it was stuck under 1 1/2 - 2 feet of overburden This one is upside down I think this is a juvenile Dipleura cephalon, but I'm not 100% sure. I'll have to clean it up to be sure. Now onto the misc finds This is one of the largest Goniatites(?) I've found here, it popped out of the matrix on the way home but it should be able to be glued back. I feel like the cone shaped fossil in the center of the piece might be a Hyolith, but I don't know for sure. A lone crinoid stem, it'd be cool to see what it looks like when prepped. Not sure what kind of fossil this is, possibly a devonian putty scraper? Here's some Brachs and Bivalves from DSR, I'm not 100% sure on the ID's so if I'm wrong please correct me on it. Goniophora chemungensis? Paraspirifer acuminatus? Mucrospirifer consobrinus? Big jumble of brachs (maybe some Bivalves too?), cool golden sheen on it. I don't think it's pyritization. Assorted brachs Devonochetes coronatus? This is on the back of the possible Hyolith piece shown above. M. mucronatus? Large brachiopod and bivalve hash plate Probably the biggest Bivalve I've ever seen, let alone found. ID unknown Orthonota undulata
