  1. For the Columbus Day weekend my girlfriend planned a three-day trip down to Southwestern Virginia as a birthday present to me. The plan was to do a little sightseeing, go on some hikes, enjoy the fall foliage, and, most importantly, collect some fossils. Unfortunately Hurricane Delta had other plans for us. As the weekend approached it looked like the entire weekend would be soaked with rain. We tried to change our reservations, but we were not allowed to postpone. Not knowing what to expect for the weekend, we made our trip. Sunday was to be my big day of fossil collecting. It was also the day that Hurricane Delta was expected to pass through Southwestern Virginia... Lucky for me, luck turned out to be on my side (at least in part). I had an all-day fossil trip planned, but due to the weather, I had to cut the trip in half. After a later start to the day than I had hoped for, we headed towards two sites that I had identified for the day. Both were exposures of the Middle Ordovician Benbolt Formation. A few showers on the drive but for the most part the rain held off while we collected. Our first stop was a large, open road cut. The limestone there is just covered with brachiopods, trilobite pieces and bryozoa I thought the number and orientation of all of the bryozoa in this hash plate were very cool There were a lot of bryozoa at this site. Some small and some large, like these pieces of Mesotrypa sp. and Batostoma sevieri My favorite bryozoan found here though was Ceramoporella sp. This piece of Corynotrypa inflata comes in a close second. This bryozoan is encrusting and was often found on the inside of loose valves of Strophomena sp. I am still trying to identify all of the brachiopods. I believe the left and bottom center ones in the second photo are Rafinesquina champlainensis while the right most one is Multicostella platys Another really interesting fossil was this undetermined sponge One of the unfortunate things about this site is that because it is so exposed, the fossils there weather very quickly. This is most apparent on all of the trilobite pieces. Here are two cephalons and a pygidium of Illaenus fieldi I think this is a right cheek and eye of Eoharpes sp. Here is an additional mystery trilobite piece
  2. Lyme Regis Brachiopods

    While looking at one of the shells in my collection that i had originally thought was a bivalve, from the stretch of beach between Lyme Regis and Charmouth, in Dorset (UK), another glance made me realize it is in fact a brachiopod: symmetry in plan view, asymmetrically sized valves in lateral view. So i dug out my British Mesozoic Fossils book and have identified it confidently as Cincta numismalis, which the book lists as occurring within the "Jamesoni Zone" of the Lower Lias at Radstock in Somerset. I am not familiar with the brachiopods of the Lower Lias at Lyme Regis in Dorset, but a quick search online using Fossilworks and plain google failed to show any other occurrences of this species from Lyme Regis. Do any of the Lias collecters here know if this is a common/widespread brachiopod taxon in both Somerset and Dorset?

  4. A bunch of fossils from Eifel

    Hello everyone! A bit ago traded some fossils with @Max-fossils and received some really cool stuff. I have only now gotten around to photographing them and would like to ask for your help with getting accurate IDs. These are all from the Givetian/ Eifelian of Eifel, Germany. I would appreciate any help with these IDs First some corals: 1. This piece was labelled as Favosites sp.
  5. Indiana Brachiopod ID

    Here's a sweet Brachiopod I found yesterday, it's quite interesting and I've only found one other like it, I am unfamiliar with the specific species but I am very interested if anyone could tell me more about it!
  6. Fossils in own backyard!

    So, I was bored one day and decided to head into my woods behind my house. It is an area named possibly after the squaw Indians. I obviously have ventured into my backyard woods many times and have found unusual things. I have been metal detecting and other things. So on this day I was looking for rocks to bust open or just anything cool. All in this day I found everything in the pictures, a rock with really rough garnet, and a 1900s bottle dump. What a weird day, I didnt know this area had so much history. I assume a glacial process carved out the valley as it is shaped like a V with the tips of the top of the V being the backyards of peoples houses. So I found this rock and bust it open after seeing shell imprints. Boom, brachiopods galore. I just think its really cool how you never know where a fossil may be hiding. I have many other chunks of this fossil aswell. I have not found much else other then the other quartz rock I believe to be coral that I'm waiting to have ID'd currently. I did find another rock that was like a sandstone possibly that also had shells and brachs but it was smaller and not as nice. I have misplaced it at the moment so no pic. For reference on where these were found check this Squaw Brook Rd, North Haledon, New Jersey. I wouldnt come looking for fossils as this is the only one I have found after hours of searching.
  7. The Day of The Echinoderm

    Firstly, a big THANK YOU to @Jeffrey P for hanging out with me for the day! What a knowledgeable, generous, and all around swell guy! If you ever get the opportunity to hunt with Jeff, I highly encourage you to. Jeff and I met at around 8:30 am, and after a quick transfer of his gear to my truck, we were off. We first drove about 45 minutes south to the small town of Wax, to hunt the Upper Mississippian. Specifically to look for blastoids and crinoid calyxes that were known to be found in the area. As it happens, luck was with us! Unfortunately, I didn't take the field pictures that I typically do. Due to the fact that I went swimming with my phone a month or so ago . I am down to using my wife's old phone that I found in the junk drawer (Yes Jeff, it's pink... ). I didn't take it out much to avoid the inevitable drop down the hill side. Especially since it doesn't even have a protective case... Jeff snapped a few pictures. Maybe he will chime in and add them when he is able. For the first few minutes we didn't find much besides crinoid stems, bryozoans, and the deflated or crushed brachiopods common to the site. The main species of brach found in the area doesn't seem to have fared well during the fossilization process. Finding a nice inflated one is a rarity. After a few minutes of adjusting our eyes to spot the small finds located here, we started to pick out the blastoids. Jeff was the first to find one, and gifted it to me as he had already collected a few on his previous trips here. Thanks Jeff for gifting me my first blastoid! Most of the blastoids, while small, were whole and nicely preserved. Here are a few examples. I did happen to find the largest blastoid from the site, and one of the larger ones Jeff had seen from here. Super pumped about this one! Crinoid calyx were also to be found here. We only found a few, but being that these were also a first for me, I was extremely excited to find them! The brachiopods I previously mentioned were abundant, and besides crinoid stems, were the most abundant fossil to be found here. Again, they are almost always deflated. Finding a nice inflated one would be a real treat. These other little Spirifer(?) brachiopods could also be found. Although they were more uncommon that the previous ones. They are very small and delicate. Often crumbling when trying to pick them up. Bivalves could be found here also, but were extremely rare. Jeff was excited to find a couple, but I struck out. Other things that could be found were crinoid stems, the odd solitary rugose coral, and of course the ever present bryozoans. We then headed to a site a few miles down the road in Leitchfield. Stay tuned!
  8. Mississippian Brachiopod ID Help

    On a recent trip to collect Carboniferous marine life I came across these brachiopods at an exposure of the Late Mississippian Wymps Gap Limestone/Mauch Chunk Formation. I have read several articles now about the fauna of the Wymps Gap Limestone but have not been able to find an identification that matches. They look a little bit like Leptaena but of course Leptaena had already gone extinct by the Late Mississippian. Any help would be greatly appreciated.
  9. More specific brachiopod

    I found this brachiopod imprint in some landscaping rocks in Colorado. It’s about 1.3 cm wide and I was wondering if anything else could be said about it other than brachiopod. Maybe get it to genus and possibly the period it’s from.
  10. Ordovician brachiopods from PA

    Hello everyone, I recently went on a trip to Pennsylvania and stopped to do some collecting in the Salona formation, I found some decent Cryptolithus parts which I am currently preparing, but most of the fossils were brachiopods. There were two types from what I could tell, smaller strophomenids and larger ones. The smaller ones I have not been able to get any ID info for but the larger ones may be Rafinesquina. Here are some of the small ones:
  11. I went up to the UP this week doing mostly sightseeing with my friends. They were aware of my predilection for rockhounding so we often made stops to areas that might bear good fossils/agates. In particular I knew there were some 'lagerstatten' in the Stonington Peninsula region of the UP. The most important formation I know of is the 'Big Hill formation' (correct me if I'm wrong). Some links about it here: https://www.researchgate.net/publication/308005515_A_new_Lagerstatte_from_the_Late_Ordovician_Big_Hill_Formation_Upper_Peninsula_Michigan https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6325806/ Now, I didn't have enough time to bother my friends into finding these exposures (and as far as I know, rock collecting in a national forest is not allowed)... However, while we were driving south on County Road 513 T on the west side of the Stonington Peninsula, headed for the lighthouse, I spied a small hillcut on the east side of the road. The hillcut was directly across from a large cemetery-- we pulled over and I had a quick look at some of the rocks there. The hillcut itself was about 20 feet tall, and maybe 600 feet long. I could see near the top of the cut a few feet of limestone bedding planes jutting out from the escarpment. Weathering had amassed a slopped pile of clay and fossils that nearly filled the ditch at the base of the hillcut. On the surface, I saw many brachiopods (different kinds of Platystrophia, possibly?) some of whom were larger than 2 inches across. I also found some small bryozoan colonies and possibly pieces of isotelus gigas molts. The pieces were too small to tell, I am unsure if this particular roadcut could yield anything fully articulated. The rock was very weak and almost clay like. Does anyone know about this roadcut? What formations might be there? I took a few small samples with me but I didn't want to start excavating, obviously. If anyone is interested I could post some pictures of what I picked up, or I could send more detailed directions. Best, Foss
  12. Looking for ID help on the last 3 fossils of my childhood collection. From Northern Arizona near Snowflake, AZ. I would appreciate any information so I can share it with my 10 year-old grandson!
  13. Hey everyone. I thought I'd share some of the things I found on my last fossil hunt. So.. Many.. Fossils! One might even say that there were a plethora of fossils. If I could, I would've taken them all with me, but sadly my backpack can only carry so many rocks. I was literally examining each rock I had, trying to decide which to carry back and which to leave behind and how many I could fit in my pants pockets before they started to fall down. Eventually I decided to just stop looking for fossils and hike back to the jeep. This lasted all of 3 seconds before I found another a beautiful byrozoan and was trying to figure out how to fit it in my pack. The byrozoan and the sponge below are my favorites since i don't see many of them and the brachipod in the matrix just looks cool. lol Its fascinating to look at these fossils and think about how Arizona used to be completely underwater long, long ago.
  14. What do you think?

    Hey guys, I'm back with another ID question. The fossil I'm trying to identify is in the 1st picture. I think that what I have is a fossilized brachiopod WITHOUT the shell. What do you guys think? It's the same general shape, but the color and textures of this fossil look different than others I've found in the area. The symmetrical textured part in between the two humps, I've never seen before. Pictures 1,2, and 5 show the fossil in question and pictures 3 and 4 show examples of other brachiopods that I've found. The last picture is an example of a brachiopod that was broken in half, exposing the animal inside. (when I uploaded the post the pictures got out of order) So anyways, that's what I think I have but I'd really appreciate your thoughts on this. Ya'll have a lot more experience with these thing than I do so I welcome your opinions. Thanks!
  15. I visited my favorite spot in the Early Kimmeridgian the other day and along with the usual ammonites, I came up with something quite interesting. It's a block out of the sponge reef facies with a Laevaptychus obliquus Aptychus as the center piece along with a Streblites tenuilobatus ammonite and a couple of smaller ones, a rhychonelloid brachiopod and even a little echinoid spine all attached to pieces of sponges. Everything is strongly calcified, so it's quite stable. I just had to abrade away the soft clay matrix and there they were.
  16. Looking to trade these fossils from the Kalkberg Formation of NY for some other Palaeozoic fossils especially from the Ordovician-Devonian. These fossils are mostly brachiopods and can be very well preserved, they are however all in pretty hard limestone and may be challenging to prep. Orthid, somewhat hard to see, it is in the top right: Meristella: Atrypa? Looks like the shell is complete just obscured by matrix Another orthid:
  17. Cyclocrinites in Arizona?

    I'm in Northern Arizona in an area full of crinoid, bryozoan, and brachiopod fossils. Recently I found what I believe might be a cyclocrinite. It's round, about the size of my thumb, and pitted like a golf ball. Its been suggested that this might be a calyx from a crinoid but since the hexagons on my fossil extend inward and not outward, I have my doubts. It looks like this thing was trapped in a pocket when it was fossilized. You can even see some space between the fossil and the material around it. The last picture shows the section of the stack that broke off, revealing the fossil inside. I thought about cracking it open but I'm concerned about damaging the fossil. Any thoughts on what this might be? If its not a cyclocrinite my other theory is that some poor caveman lost his golf ball in a water hazard on a 500 million years ago. I'm new to the forum and you guys are the experts here so any help would be appreciated!
  18. Hello. I'm working on organizing my collection and was wondering if anyone could help me with some identifications. Thanks for any help. I don't have any info on this one. I think it is a Mucrospirifer brachiopod. Can someone confirm this? Help with the species name would be appreciated. Thanks. These are crinoid stems. I don't have any further information. Does anyone know the species, where they came from, or the approximate age? Thanks. I think this is a dolphin tooth. It was found on the Ernst Ranch in Bakersfield, California. Can anyone help me identify it further? Thanks. Last, here are some fossils I collected when I was young. They were found near Thermopolis, Wyoming. They were found on one of the paleontology digs that the local museum hosts. I think they are orthoconic nautiloids, but I am not sure. 6 year old me was not taking good notes. Thanks for any ID help.
  19. Grandma's Brachiopod

    My grandmother (rest her soul) was a high school science teacher way back in the day. She was also a SERIOUS rockhound. These days her extensive collection of odds and ends lives in the family attic. I was going through some of the boxes when I stumbled on this gorgeous pyrite encrusted brachiopod. Unfortunately many of the tags and labels for her pieces haven't survived into the present day, so I've been curious about what species this is and where it might be from. I've heard that Ohio has a deposit with lots of pyrite fossils and brachiopods. Anyone know of any other places where such a fossil might have come from, or is Ohio the most likely?
  20. Pentamerid?

    Going through my trip bucket from a June visit up through the Silurian of the Bruce Peninsula, I encountered what I suspect might be pentamerid brachs, but wasn't entirely certain. Each of them average about 4-5 cm. Although the photo does not capture the "shine" well, the black that outlines some of them, including some of the bits, is very high gloss (like obsidian or some forms of tar). These were unlike any of the surrounding Eramosa Fm, so likely an erratic of sorts.
  21. Devonian Identification Dilemma

    Recently I have taken interest in fossil hunting after discovering a plethora of fossils from some farmland in Southern Indiana. It is my understanding the fossils are from the Devonian period. My grandsons (5 and 6 years old) and I have collected several specimens I’ve the last couple of months. I have been searching the Internet for weeks trying to correctly identify our finds and just when I think I have something identified —I find other possibilities. I would like to make displays for the grandkids and label our other collections appropriately. I am in hopes this community would help identify the specimens, and provide advice on how best to label the fossils. I appreciate any assistance that can be provided. Thanks. —Bill Shingleton PS: All the fossils depicted are from Jeffersonville, IN.
  22. Howdy! So I was out in West Texas this last weekend trying to hunt down some new echinoids (will post those later!) but i came across some odd looking brachiopods. I am 99 percent sure the formation was Buda (it's kind of hard to be certain as I am no geologist -but that is what I pinpointed on the Texas Geological map, but I might have been at the wrong roadcut, too). The other fossils I found there were Texigryphaea and Neithia texana. I am familiar with the Brachiopod Kingena wacoensis in the Georgetown formation of Central Texas Cretacous. I wasn't sure if Kingena is found in the Buda formtion for one thing. A second thing, these look very different than Kingena. These have a "dip" in them more like Pennsylvanian brachiopod Composita. All the other Kingena I have found are straight "lipped". Any help would be appreciated!
  23. Hello everyone, I am looking to get some more definitive IDs for these finds from the Lower Devonian Kalkberg Formation in NY. I have some idea for what these guys might be but I would like to see other opinions from the forum before I start labeling them. I will post more brachiopods as I take and process pictures, but here are the first few: 1. I believe these are three might be Rhipidomella
  24. Just before the pandemic locked everything down, I went on a geology hike near Comb Ridge in southern Utah with Professor Gary Gianniny, Chairman of the Department of Geosciences at Fort Lewis College in Durango, Colorado. I’m working on a book about the canyon country of the Southwest and this was a great opportunity to learn from an expert in its geology. While the hike primarily focused on geology, you can’t tour this region without seeing fossils. All our fossil collecting was catch-and-release. I took photos but did not bring back any physical specimens. Here’s a quick overview of our hike. We started from a point on the southeast side of a feature called the Monument Upwarp, about 16 miles west of the town of Bluff, Utah. Here is a Google Maps satellite view of the area: And here is an aerial photo I found on the Internet here showing where we hiked (the lower left corner). Comb Ridge is the 500-foot high escarpment at the top right of the photo running north to the horizon. Comb Wash is the gully just to its left, and the San Juan River is on the lower right. Our starting point overlooked an abandoned meander of the River, just off the left side of the aerial photo. The river long ago took a shortcut by punching through a narrow wall of the meander (out of site behind the near slope), leaving it now abandoned. It reminded me of a gigantic, empty baseball stadium: From there, we turned east and went down the side of cliffs bordering Comb Wash. During the first part of the hike on the top of the Monument Upwarp we were in the Honaker Trail Formation, a marine limestone of the Pennsylvanian Period. Gary has done quite a bit of research on these limestones. He pointed out numerous examples of fossils in this formation. The first was a brachiopod (I didn’t get the species). Notice the spring-like squiggly lines along the hinge line at the top. Gary said these are indicative of it being a brachiopod: Here is an example of crinoid pieces. Gary said this limestone is made up of about 90% crinoid fragments: And here’s an example of a clam (again, no idea of the species): As we descended, the layers got younger because of the way they were tilted (you can see this by studying the aerial photograph). When we got to the red layers, Gary explained we were now crossing into the Halgaito Formation, terrestrial sandstones of the Permian Period. He pointed out fossils of plant roots encrusted in calcium carbonate (the light gray areas). These are called rhizoliths. He said you can still see rhizoliths forming today on the roots of modern plants. Gary went through a lot more about the geology of the area, but that’s about it for fossils. Like most geologists who frequently get out onto the landscape, Gary was in good physical condition. I however, was another story. The 600-foot return climb across gullies, boulder fields, and loose scree was about the limit of my sorry physical condition. But it was a great experience and one I wouldn’t hesitate to do again.
