Relevant info first: This was found in Petoskey Michigan while looking for Petoskey stones. It was found in partially buried in sand. It is quite large and rather heavy. As pictured in picture 5, there is some sort of opening at the end? I can't get a very good picture of the inside, it's hard to get light where i need it and take a picture. the hole looks to maybe be about a 1/2 mm deep, and less than that wide. I took to reddit, albeit with less detailed photos and was told it was a straight shelled nautiloid cephalopod from the paleozoic, and that it was a brevicone, which I'm hoping someone can confirm or deny, or point me towards relevant info. I was trying to find more and found this on your forum, which is the first thing I've found online that actually looks something close to what I have: Anyways, Thanks for looking, and any help you can offer.

Request for feedback on fossil field guide visual layout
pefty posted a topic in Questions & Answers
I'm working up a series of fossil field guides for various formations. I'd like to provide a visual indicator of which fossils are rare, which are common, and which are abundant, without getting in the way of the visual layout of the fossils & identifying information. The complete set of categories I am working with is {Abundant, Common, Rare, Very Rare, Common to Abundant, Rare to Abundant, Rare to Common, Present, and Questionable}. Has anyone seen a good way that a field guide of any kind has provided such a visual indicator as a page-wide element of visual layout? Attached is my first draft for the brachiopods of the Zaleski Flint Member of the Allegheny Formation (Pennsylvanian) of Ohio. All feedback welcome! Thanks.

Hello everyone! I recently received a package from @connorp filled with wonderful brachiopods! I am not exactly sure as to what the IDs for some of them are so I thought I would ask here Any help is greatly appreciated! Thank you 1. Silica shale. These look like Atrypa sp. but I am not sure what species are present in this formation. 3 cm wide 2. Same formation. Stropheodonta? 2 cm wide 3. This is from the Ordovician Liberty Formation. Rhynchonellid not sure what genus or species 1.5 cm wide 4. Some kind of strophomenid from the Mifflin Member of the Platteville formation 1.5 cm wide 5. Same formation .5 cm wide

I have one simple question, How do we know eurypterid walking legs are legs? I find eurypterids to be one of the strangest Paleozoic creatures and while looking at some pictures of them I noticed how similar eurypterid walking legs and wobbegong mouths are. I have not seen yet just a single eurypterid walking leg fossilized alone. Any help would be appreciated thanks in advance

Here are some finds from a late August to early September long loop road trip, fossil hunting through Ohio, Michigan, Wisconsin, Indiana and Kentucky. I'll appreciate detailed specimen identification help. First photo shows brachiopods & a trilobite from the Devonian Silica Shale Formation near Sylvania, northwestern Ohio.

Ya know, I'm great at plant identification if it's currently growing in my region. Dive back to the Paleozoic and I can tell Calamites from Cordaites, but that's about my limit without a book in hand. So far, I've had 8 and I still don't know what this is! I'm pondering the frond-like object running diagonally across the center of the picture. It looks like a fruiting body from Cordaites, but it lacks the sporophyll. It also resembles Corynepteris angustissima, but the only illustration I can find lacks sufficient detail. This came from a mid-late Pennsylvanian Lewellyn Formation exposure in Columbia County, PA. It's about 4 inches (10cm) long.

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.

Im a member from Hong Kong and I have been here for already a year but never actually properly introduced myself or talked much. Im a high school student that have a passion for paleontology,I am interested in a broad range of fossils(almost everything) and have a small collection with a knightia,my first fossil which you guys taught me to prep,an oreodont jaw,dino bone chunks, two ammonites, an amber and 2 shark teeth.I hope to learn about paleontology and join the forum to connect and share our ideas and advice for fossil collecting. All the members here have been amazingly helpful people,I hope one day I can contribute to the forum like all you do

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.

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!

Why are crinoids usually the only type of fossil in an area?
Digi posted a topic in Questions & Answers
As the title states, why do crinoids often show up alone as the sole type of fossil in an area? There's a quarry near my house I've been to a few times that has crinoid bearing marble. I've found a few crinoid stem pieces in rocks, but I don't really understand why they're the only type of fossil (unless you count chert.) The area is Permian-Devonian, so if crinoids fossilized shouldn't plenty of other common marine animals have fossilized too? Or am I thinking too narrowly and there's a good chance they DID fossilize and I simply have to look a little deeper? I'm not too knowledgable on the paleozoic so I appreciate any answers. -
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?

Hi all, Is this a trace fossil, worm holes? If yes, that would be the first I've found. The holes measure about 1mm to 2mm in diameter. I think it's odd that all of the larger diameter holes are perfectly parallel to each other, while the smaller diameter holes seem to run perpendicular to the larger ones. Also, what are the dark thread-like shapes all over this rock. I've never seen those on my finds either. Rock measures 2cm tall, 1.5cm wide. Lake Michigan beach find, WI, this could be either ordovician, silurian or devonian. TIA! front: back bottom

Hi! A recent walk in the woods resulted in the discovery of this nautiloid. I found it in Wilson County, TN which is Ordovician. I am super excited about this because we found it in the woods on the property where I grew up, which means I probably walked past it a million times, and it's 3D so it shows the the siphuncle, and the outside of the phragmocone. We did not have anything to measure it with but I would estimate it to be about 12cm (5in). So my questions are these: I think first verify what I think this is and what I see as I am new to this. I have looked around the internet for genus/species of Orthoceras found in TN, but can't find anything, does anyone know? The fossil is covered with moss, what is the best way to clean it without breaking anything (once we drag this monster rock out of the woods and to the house)? Thank you so much for opinion/advice/help!

Hello everyone! I'm currently in the London, UK area (though I repeatedly travel back and forth between Europe and Asia) and decided to join the forums because I'm hoping to start a PhD in Paleontology relatively soon. I attended the Paleontology Associations virtual meet up early this year and really enjoyed it, and after it finished really missed having less formal interactions with people who are also interested in fossils. So, I thought it would be great to be able to see so many peoples collections and specimens and so I decided to join. I'm mostly interested in macrofossils from the Paleozoic-Mesozoic time frame (though Terror birds will always hold a special place in my heart as well!). In my BSc I studied in depth Ammonites from the lower lias formation in the South of England and in my MSc I studied Sauropodomorph and Ornithischian dinosaurs. My current self-collected collection consists of several species of Ammonites (from Dorset in the lower lias), a sample of pipe rock (from Scotland) and several Gryphaea fossils (from several locations across Whales). I've also been lucky enough to purchase/be gifted several other fossils including Spinosaurus teeth, Eggshell fragments, fossiled Amber, a Hadrosaur toe bone and a Ceratopsian tooth. I look forward to chatting with you all in the future

I found this beauty yesterday in a gravel in central Poland, so it's an ice age gift from Baltic Sea or Scandinavia, Ordovician or Silurian in age. Any ideas? I'm thinking... maybe a billingsellid of some sort? I'm not good at Palaeozoic brachiopods.

A friend has a trilobite marked as Eoptychoparia piochensis from the Cambrian of Pioche, Nevada (Pioche Formation). I wasn't familiar with it and looked it up but couldn't find much info at all. Is that genus valid (maybe just rare)? I collected a couple of different spots out there about twenty years ago - didn't find much - and don't remember hearing about E. piochensis. Thanks, Jess

I've had these few pieces in one of my drawers for years and I got looking at them again today. Three of them are clearly some form of Fusulinid or other Foram, the other I think is oolite. I don't remember where I got them but suffice it to say I didn't collect them myself. I guess I don't expect much info to come in about these, but in the off-chance that anyone recognizes the material I'd appreciate knowing about it. They each seem to be quite distinctive so there is hope. The only Fusulinid I know of in B.C. is Yabeina from the Cache Creek area (Marble Canyon), which I've read about in books about BC geology, but I've never collected at that spot so I wouldn't know how to recognize it, if any of my pieces are from there. Otherwise my best guess is they're from somewhere in the US where these things are more readily available.

Hello everyone! My name is Costontine and I have just recently got into collecting fossils as a hobby. Mostly I crack open TN marble for fossils, and I am looking for an appropriate air tool to help excavate the rock aside from the rather rough hammer and chisel. If anyone has any advice for one around 100 it is greatly appreciated! Thanks!

Hello, I have been fossil hunting in Northeast Oklahoma near lake shores in an area where I have found bivalve, Bracheopod, and Crinoid fossils. I have been separating them into similar groups to identify them. May I get some help on this particular fossil type? Found in Northeast Oklahoma near the Lake Skiatook area. I am a newbie when it comes to fossil identification so I may be wrong on my tags.

Unknown large trilobite- fake, or just badly prepped?
Parthicus posted a topic in Is It Real? How to Recognize Fossil Fabrications
I am hoping someone can help me with this large unknown trilobite. It was given to me many years ago (late 1980s) by my father, along with some other trilobites and other fossils, as a Christmas gift. He acquired the fossils from a member of the local fossil club (Delaware Valley Paleontological Society) and most were carefully labeled, but this one was missing its label. It is a large, partially enrolled trilobite (15 cm from "nose" to tail if unrolled and 6.5 cm at the widest point); there are small bumps down the middle of the thorax and on the glabellum. It is on a chunk of matrix that lets it stand on its own, and it is a cool display piece. But looking at it closely, it looks...wrong. There's not much detail on the eyes (which seems to be usual in fakes, but can also mean a poorly-prepped real specimen) and overall it just looks wrong, in a way that I can't quite articulate (which again could mean fake, or badly-prepped but real). So, my questions are: 1. Is this, in your opinion, a real trilobite that was badly prepped, or a fake? I would appreciate if you can point out specific features that lead you to your decision. 2. If it is real, can you hazard a guess as to genus/species, and (this is a stretch) where it might come from? The scrape marks on the matrix resemble what I've seen on some Moroccan specimens. However, the other trilobites it was sold with are all from the United States, except for one from Pakistan (!), if that means anything. I think this trilobite resembles Calymene in general shape and size, but I don't know much about trilobites (if that wasn't already obvious) and I could easily be wrong. Thanks in advance for any help you can give. Let me know if additional photos would help- my photography isn't great, but I'll do the best I can.
