I have satisfied my urge to name most of the brachs I find in the Dundee. This one has eluded me, though. It is very common in the fossiliferous layers. Big ones may be 3 cm long. I only ever find this valve, out of hundreds of specimens. Anybody know what this is? PS. Sorry about the inches on the ruler. 1 inch is about 2.5 cm.

About 10 days ago @Jeffrey P and I collected at an exposure near his house that is full of Lower Devonian brachiopods. I was amazed by the diversity of brachiopods at the site. But what makes this site so special also makes it tough to identify everything. I did my best to identify many of my finds, but I am a bit stumped on several others. A lot of the sketches in Linsley's plates are starting to look alike. I could really use some help, even if it is a guess on the family or genus. Please let me know what you think. Any help is greatly appreciated. Thank you! #1- Spirinella modesta? #2 #3- Cyrtina varia? #4 #5- Nucleospira ventricosa? #6 #7 #8 #9 #10 #11 #12- Cloudella stewarti? #13 #14 #15- juvenile Meristella laevis?

I went with the Delaware Valley Paleontological Society to a few spots in Central New York last month. Cole Hill Rd. in Hubbardsville has several outcrops on private land where the owners are willing to share with fossil hunters. We scrabbled up and down the scree - Whee- and found our fill of trilo-bits, including one Dipleura cephalon covered with druse calcite, plus oodles of brachiopods, nautiloids, straight-shelled cephalopods, gastropods of all different shapes, and bivalves. I learned a tough lesson that afternoon. Always wrap your specimens as you go. Not only will they keep from breaking, but they are easier to find when your bucket tips and tumbles down the hillside across countless tons of scree There were lots of pained faces around me as I hunted down the things I'd already found.. It took me half an hour to recover everything I could, but the best ones managed to make it home. Dilpeura trilobite cephalon Another trilobite cephalon, found by someone else in the group. This one is covered in sparkling calcite. Crinoid holdfast? with Ptomatis rudis gastropod unknown, probably nautiloid Cornellites fasculata bivalve Palaeozygopleura sp. misc. unknown brachiopods If anyone has any ideas, I'd like to hear them. This spine-shaped object is about 6 inches long. I'd discount it as variations in the rock color, but the left end is curved outward from the matrix. Worm trace fossil. They made carpets of these on the sea floor.

Hello fossil forum, first time poster here. I found this rock in Tully, NY. It’s a small round stone with what appears to be a bit of brachiopod shell sticking out of it. My question comes from the fact that it’s an extremely tough rock - all of the exposed rock at the site was extremely flaky shale which barely held together when subjected to any force. I found this rock in situ and pulled it directly from the shale around it. My first guess is that it’s just calcified but I’d like to know if there’s anything more to this strange rock. Thank you!

Yesterday I decided to make the journey across the border to check out the Penn Dixie site. My ever obliging bf (pictured) joined me as another set of eyes and so he could have fun hitting things with a hammer. Neither of us had ever done anything like this so I wasn't really sure what to expect! But I think we got a pretty good haul for a first time visit. Shout out to our tour guide Kevin for the nice intro to the site and tips on tool use. I am already itching to go back, I had to force myself to leave because I was certain a nice plate of multiple prone trilobites was just certain to be in the next shale we split... Will reply with more pics

Hello everyone, Recently I visited a golf course in Falls Church, Virginia - Fairfax county for any who are not familiar with that particular city. I recognized that I was likely to be on Culpeper Basin strata and noticed that there were numerous decorative boulders around the course. Due to their size I suspected that they had probably been sourced locally, and I took the opportunity to see if any might contain fossils. Although many of the boulders matched the Balls Bluff Siltstone rocks that I have encountered in my local stream site, I knew it was a stretch to hope for fossils and I kept my eye out mostly for carbonized plant fragments. After a while, I came upon one boulder that did not look radically different from those I had seen before - until I took a closer look. The boulder contained abundant impressions of what appear to primarily be brachiopods but which could also include some bivalves. Below are some photographs that I took of some of the larger fossils: Impression #1: Looks to be a brachiopod impression though I am not experienced enough in this area to rule out bivalve. Impression #2: Brachiopod? at the top right of the photograph and assorted material. Impression #3: Impression #4: Impression #5: Additional photograph of the boulder (apologies for lack of scale): Since it was a boulder I could not collect the specimen. As such, I cannot take more photographs of the boulder. Considering the fauna present on the piece I highly doubt that it came from the Culpeper Basin - as far as I know Unio sp. is the only bivalve known from Culpeper strata and to my eye these more closely resemble brachiopods. If they are not from the Culpeper Basin, where might the rock have been sourced from? The nearest Devonian-aged formations are the Mahantango and Foreknobs formations with the Needmore Shale being a bit farther away. Do the fossils or the rock resemble what one might expect from one of these formations?

Beltzville State Park - Middle Devonian (Mahantango Formation)
Masonk posted a topic in Fossil Hunting Trips
Family and I took a trip to Beltzville State Park earlier this week. We stayed around the lake, looking along the shoreline and wading through water. Found some pretty cool Middle Devonian fossils. My wife lucked out with two Trilobite pieces, one of which is a really nice head imprint. I'm still working on identification, so please bare with me. Any help of course is appreciated. Coin is 22mm Shoreline Trilobite head (Phacops rana?) surrounded by Crinoid stems Trilobite (Phacops rana?) - lower abdomen Crinoid stems Crinoid stems Pleurodictyum tabulate coral (?) and brachiopod Crinoid stems Brachiopods and I'm not sure what the orange/black dotted impression is.

We recently found these brachiopods and I was wondering if anyone is able to provide any more information about who they are. They were collected on the Western cost of Newfoundland and they are early to middle ordovician in age. If you have any other questions regarding the fossils let me know and I will do my best to answer. Anything would help, thanks!

Age: Ordovician: Approx. 454-452 Mya Formation: Decorah Shale Location Grant County, Wi Amidst the frequent outcroppings of Platteville Limestone in Southern Wisconsin, you occasionally encounter the overlying Decorah Shale. From what I read this formation is more frequent north of Grant County, and in Minnesota as well. The outcrop itself is roughly 200 feet in length, and only extends about 6 feet from the ground. Its located in a very remote area, amongst a sea of corn fields. Here are a couple finds from my third trip to this locality. Here is a complete crinoid calyx with associated pinnule filtering appendages. Complete crinoids are much more common in Silurian/Devonian stratum. Next is a hashplate, with a few assorted brachiopods and crinoid fragments. There were also a handful of brachiopods to be found alone as well. All of these are very similar to the Ordovician Lepidocyclus perlamellosa/H. capax. Although these were much smaller in size. A single Lingula inarticulate brachiopod, which was a huge surprise since this was my first one ever. I found a mid sized orthoconic nautiloid. This one is 7 inches (17.7 cm) in length. The approximate width at its widest end is 2 3/4 (6.9 cm). Note the visible septa markings on the specimen. This is an internal mold, so structure is a little different from that of a normal mineralized specimen. Not the largest from this site, as others I've recovered push 25 inches (63.5 cm). The internal siphuncle is exhibited here in cross section: I marked the cross section and direction of the siphuncle here. Phragmocones from this locality only preserve as internal molds without any calcified structure. As a result of poor preservation they can be difficult to spot. With a trained eye, it becomes significantly easier. Here are some additional brachiopods that I dug out from this locality. A fennestellid bryozoan as well. There were a few, but none to write home about unfortunately. My favorite finds at this location are by far the large nautiloids, which have been consistently produced from here. (If only I could find one at 6 feet now ) If anyone has an i.d for that crinoid calyx, I'd be happy to post measurements or more detailed photos. Other than that I hope to run out to Indiana sometime within the month, maybe I'll see some of you out there. -Jonah

I don’t want to say more about the specifics of the location quite yet- i’d like to actually make sure this place is a fossil bed, and that this one find wasn’t just a fluke. I also have to talk more with the land owners, ensure they’d be okay with the site becoming publicly known, as well as work out if they are okay with me doing some more extensive searching and digging in the bedrock. But nonetheless, i wanted to share the find itself because i am so so so happy, as this is my first fossil (and potential site) that i’ve ever found by doing my own geological research, and i wanted to share it here. I hope once i speak with the landowners more, as well as find at least one more fossil to confirm its not a fluke, i can get permission to post the location!

This brach is really odd. Possibly a very weathered (pre-burial) Parazyga hirsuta?

Fossil Trip 11/2021 West VA Silurian ( Rose Hill Formation)
Rexofspades posted a topic in Fossil Hunting Trips
Hi everyone, went on a nice little expedition into West VA over thanksgiving break. tried my hand on checking out the rose hill formation in Waiteville. lovely time out with some beautiful scenery and farms. The sandstone was sparse fossil wise, but I did find three pieces with some interesting stuff to ponder. here are each of the three rocks, labeled Specimens A-C Specimen A looks like it has some simple fossil impression. on first inspection there's some nice Ostracods and a couple brachiopod impressions in the middle. but on closer inspection on the edges I noticed there is a possible mold of a trilobite pygidium. (Likely Calymene Cresapensis) ostracods and brachiopod impressions. Here are closeups of the trilobite impression. lastly here are a couple impressions that might be something. Specimen B Specimen B has the Faintest brachiopod impression (According to this book I read it looks like Cupulastrum Neglectum) there's a weird looking impression I have no idea what it is. other weird impressions on the side. Specimen C I think i found a hash plate of trilobite chunks here, although Im not familiar with the geology of this place so it could just be concretion. this piece also has a definite Trilobite in it on the side. Trilobite. I do not know which part of it this is, could be Pygidium or Thorax. Possible cephalon piece? Please let me know if I missed any ID's or am way off on my guesses here. as always, message if you want to see a different side/ angle of something.

Found in Northeast Costilla County Colorado in the Sangre de Cristo Mountains at almost 10,000 feet elevation. From limited research I believe they may be brachiopods from late Paleozoic? There are shells and snail looking things. Found next to each other but not together in the same piece of rock rock. I was wondering what other kinds of fossils may be in this same area. Like fish or trilobites? Thanks

I found these Devonian bivalves (?) at the Milwaukee formation at estabrooke park in Milwaukee Wisconsin. I think the first one could be a bivalved arthropod like an ostracod and the second could be part of a brachiopod. Any help is appreciated! Thanks. Sorry for lack of scale! I just put one in my rockhounding bag.
