Wondering if these tiny fish fragments can be identified? These are about the size of a grain of sand about 8-10,000 years old ancestral Lake michigan.

Been doing some micro matrix picking lately, and I came across this tooth. First thought was lemon, but the root is throwing me off. Shape doesn’t seem right for a lemon. @hemipristis @Al Dente @MarcoSr I’d love your help! Size is like… 2mm if that.

I was wondering how you display your small dinosaur teeth? I was conserding Gem Jar cases. I just got a small dutch mosasaur tooth and some perfecr abelisaurid sp. crowns & and as I continue my fossil teeth expension. I'd like to give them the display they deserve. How do you guys and girls do it? Please show some pictures and tips! Would be greatfull!

Dipping my toe in to micro air abrasion prep with a tricky fossil crab
mamlambo posted a topic in Fossil Preparation
I've got some experience with air scribes and acid (acetic) but haven't used air abrasion much. I recently got a new micro air abrasion unit and tried it out on a sticky crab that had a growth on it with some good results using dolomite. Before photo: After photo (work in progress, about 25 of prep time): One of the challenges I have is that is it really hard to find media between 50 and 100 microns here in New Zealand and shipping is quite expensive. I can sift my own dolomite, it just takes ages! I wonder if anyone has any tips for finding iron powder or is there an easy way to make your own? Here's a video of the unit I am using as well as my setup, any help / suggestions welcomed!

Hi, JP. I saw your comment on another thread, and decided I would try it out on some White River micro matrix I have been working on, and it works pretty well! Much faster and easier! Just thought I would share some pics of the teeth I have found so far: My brother actually found a small lizard jaw sitting on top of the micro matrix. The lizard jaw is near the center of the container. I have searched through probably less than one gallon of sifted micro matrix. And to me, that seems pretty good! Cheers and Shalom, -Micah

I have problem with this enigmatic shark tooth. Location- Poland, Zabierzów (Cracow Area) Age- Cretaceous. Turonian Size- 2mm

Hello Everyone, I recently went on a trip to Norfolk (I'll do a trip report soon) and collected some bulk samples from the West Runton Freshwater Bed, a famous Pleistocene deposit. I've been washing the first batch of it today and found several small seeds (~1-4mm) which I currently have in a small jar of water as a few started to split when they began to dry. I was wondering if anyone could advise me on how to preserve and stabilise the seeds. My goal is to be able to try micro mounting them to take pictures and see how many species there are, I've counted at least 6 different shapes so far. The seeds themselves are subfossil and as a result still quite fragile and pliable. while some of them may survive controlled drying without splitting I'm intrigued to see if anyone has another suggestion. Thanks for the help, Benton

I found these tiny fossils amongst some micros collected at the C&D Canal (Late Cretaceous; Mount Laurel Formation). I am fairly certain that #2 is a sea star ossicle. I am less certain about #1 and #3. They remind me a little bit of crinoid pieces and I have found crinoid material at the site. Both have a subtle pore-like pattern on them that is reminiscent of the surface texture of some crinoid dorsal cups I collected in the Pennsylvanian of Texas. Any help would be greatly appreciated. #1- the big one in the middle is 5mm #2- 3mm #3- 3mm

What and where are the examples of oldest micro fossils?
Lucky1 posted a topic in Micro-paleontology
Just as the title asks. What are the oldest known micro fossils and from when. What examples are available to see? My other ask is where can I find clear examples of algae ( oldest) and other fungi or alike filaments? My finds with algae and fungi are what seem to be sporulating nodes from fungi while the algae forms in chains like 6's stacked alternating direction. I say fungi because they appear to show clamp connections through the hypha and asexual sporulation without a fruiting body. The interesting thing of some of those connections cross to what appear to be other fungi that look completely different. This could be due to like what we see today where the incomplete genetic mycelium needing to pair with another to create a sexually viable colony. I have found some cool stuff... no one believes me. That's just fine. I have a clear picture of an isopod that looks like a 120micron ish. I need to do the picture pixel scale for a better measurement. It came from inside a solid junk of quartz cavity. My geology, according to my states survey, puts me Precambrian and earlier. I thought at one point it was up to the Ordovician but more research found that is not the case. Ignore Nevada. I am not in Nevada. I will do the work and share my findings when I am done and satisfied I have no contamination with repeatable findings in impossible places for them to reach. If you don't agree with me, cool, you can tell me! I'm ok with it. Please also answer my questions if you can though. Thanks every one! -
I have been fossil hunting in the Monmouth County, NJ area for quite a few trips now, and I have accumulated a good amount of fossils I haven’t been able to ID. Here are some of them: Note: feel free to ask for more angles; I didn’t want to post too many images. 1 inch for scale Found in Ramanessin - no idea what it is Found in both brooks - 5 in middle look to be same species; I believe far-right is pycnodont or hadrodus Left - found in Ramanessin; think its coral Right - found in Big Brook; thought it was coral when I found it but I’m now leaning toward coprolite Both from Ramanessin; Left seems to be an imprint from some sort of spine; My father thinks the one on the right is some sort of crinoid Both found in Big Brook; Possible reptile teeth; maybe mosasaur or croc, though they are very small Found in both brooks; left seems to be a possible Pachyrhizodus; all have distinct carinae Found in Ramanessin - potential hadrosaurus tooth fragment Thanks in advance for your help!

Went on a trip with Dallas Paleo Society to a Moss Creek site on private land. just ran a small batch of the matrix that I brought back. These are the "bigs", size reference is about 4 pieces per inch. Just finished this batch yesterday and haven't had a chance to do any id work yet. Variety of shark teeth Fish teeth Vertebra Cool and unique teeth Completely unknown More cool and unique (at least to me) Any help is appreciated as always! Hope you enjoy!

So a couple of weeks ago, I, along with my younger brother, decided to embark on our first field trip with the Dallas Paleontological Society. The destination was Moss Creek, a decently sized waterway on private property that feeds into the NSR. Just like in the main river, we were seeking a red layer exposure of the Ozan Fm (though I read that this red layer is different from the one at the river). This site is famous for its abundance of marine microfossils, namely shark/fish teeth. One of the people on the trip was a researcher (Shawn Hamm) who is currently finishing up a paper on this very site. I hope to read it once it's published! Anyways, the day was miserably hot as expected, but the scenery and air of discovery made up for it. My brother and I took a more secluded route, traveling downstream whereas most headed upstream. After a bit of searching, I came across a part of the creek bed that was red and, upon close inspection, was filled with tiny black phosphatic fossils. Because the matrix of the layer is so sticky, we couldn't really sift through it at the site. Instead, we, like everyone else, filled up a bucket and took it back to our car. It was a fun day and I met a lot of interesting people. One member told me to use baking soda to break up the matrix and that advice worked like a charm! I'm not sure about a lot of these IDs so feel free to correct me. If you know any species names feel free to drop those too . Here are the pictures of the highlight finds. Sorry the quality is bad... taking pictures of things this small was more difficult than expected: Fishes Lots of Enchodus Fangs and Jaw Sections Lots of Hadrodus Teeth Pachyrhizodus? Teeth Protosphyraena? Teeth. Really not 100% on this ID Pycnodont Teeth Fish Neural Spine. 2nd photo is compared to an X-Fish neural spine I found in Austin. Love the size discrepancy of the two. Fish Verts (Left) and Shark Vert (Right) Sharks Hybodont Shark Tooth. This is one of my favorites. Looks like Lonchidion? but that's just my guess. Lots of Pseudocorax Teeth Lots of un-ID Shark Teeth. Distinguishing between Scapanorhynchus, Carcharias, etc. is way above my pay grade . Trust me, I tried... Cretalamna appendiculata Tooth. By far the biggest tooth. Protolamna? Teeth Squalicorax Teeth. For some reason they all came out broken. Unidentified Tooth. Pathological? The crown is just a flat edge. Shark Coprolite? It's ringed like the ones I've seen online. Sawfish Ischyrhiza Oral Teeth Ischyrhiza? Rostral Teeth Ptychotrygon? Oral Teeth Cantioscyllium? Oral Teeth Misc./Enigmatic Finds Brittle Star Parts? Part of an Urchin? It's rounded and the center has a protrusion for where a spine once was. Kinda looks like a denticle, but may be some weird tooth? Bivalves If you would like any additional pics, let me know. Thanks for reading!

Went through about half a pint of the sifted matrix I brought home from Aurora. There were shark teeth as I had expected, way more urchin spines than I would have guessed and some small coral like pieces I'm not sure exactly what they are. Nice sample including the pieces in the top left I am trying to identify: Tried taking pic with clip on micro lens for the phone:

Any idea what this could be? Very tiny..about 2mm. Silurian , crab orchard.

I have discovered the main draw back of Micro Matrix fossil hunting. Accidently tipping over the container you are putting your tiny finds in. Even though I have wood floors, I was unable to find the tiny perfectly preserved crab claw WITH BOTH PINCERS. I hope your night is going better than mine. Pity Party at my house.

Hope everyone is doing well. I miss being in a creek or on the beach, but all in due time. Every night I have been relaxing going through different types of matrix. Last week I started seperating ray teeth from Bakersfield matrix that I went through last week. I believe the these are three shark teeth that are not ray teeth. All measurements are in MM. Any feedback (as always) is much appreciated!! 1. This tooth has a little white nub sticking out. I was thinking something pathological like a smoothhound? 2. I am pretty confident this is a smoothound, mustelus lateral tooth. If it is, pretty excited because it will be a first of this type for me. Also it fell off my tweezers when I was putting it back in the gem jar. I am absolutely shocked that I found the little 1mm piece of.... happiness! 2. 3. For the last tooth I am stumped. It has a crazy perfect circle on top of the tooth. I was thinking something like a basking or whale shark. But what I have learned over the past year and half on the forum is, when in doubt... it pathological something something. Any feedback on this would be great. I hope this post helps future people looking at similar teeth! Everyone on this forum is amazing!

I looked through the non-shark tooth finds and there was a lot I didn’t know. Hopefully some of this can be identified. 1. Dolphin teeth, can they be further identified? I’m not sure if all these are cetacean but at least some are. @Boesse I’d appreciate your input. 2. a large tooth, is it a big fish or something else? 3. An image of more fish teeth, all appear to be from the same type. 4. This variety of fish teeth is much more narrow. 5. the last fish tooth variety, flat and broad. 6. I have a feeling, not all these are the same thing but anyone know what it is? 7. Very strange and I have no idea but it’s symmetric. 8. Fish tooth maybe? It splits in to two parts at the one end. 9. it sort of resembles a crab carapace but I doubt it since I haven’t heard of those from here. 10. No idea, looks like two plates of something. 11. Is this identifiable? It looks like bone but has a strange outer layer. 12. I have no idea what this is but it has a very cylindrical shape. 13. It almost looks like a shark tooth but on the back there is no sign of enamel. 14. Any idea what this is? I’ve seen an image of these before but they weren’t identified. 15. I assume this is a fish part but is it possible to tell which part? 16. Last, finally, it looks like a tiny vertebra but the sides show no vertebra structure. There is also a small hole that goes all the way through. Attached is a view from the top and an oblique view that shows the side. Like always, thank you for your help. The knowledge here is unparalleled.

I was recently gifted some micro matrix from Aurora, North Carolina for Christmas and have been looking for tiny goodies. It is in single digit Fahrenheit temperature and it’s too dusty to search inside so can’t look today but I can hopefully receive some shark teeth IDs. There are some other unknowns but I haven’t photographed them yet and will wait to post until I am finished searching. I never knew ruining your neck could be so addictive. if you need more photos, I can get some. 1. Very strange and I have no idea 2. One of the bigger pieces and incomplete. Some sort of mako? 3. This one has quite a sharp curve and thin root. 4. From thin root to wide. Although it’s kind of worn can the large root be identifiable? 5. Strange tooth with wide root. Do these strange roots have to do with tooth position? 6. This one is similar to 5 only with an even wider root. 7. This one almost doesn’t even look like a shark tooth. Rhincodon? 8. The largest (proportionally) strangest root on a shark tooth I have. Looks like some big hair-do. No idea how this tooth would have been any help to the shark. Thank you for any and all help.

Hello just wanted to show you guys this pebble I found from a jurrasic coast in Oman. does anyone know what the spiky shell at the bottom is? thank you for your time.!

Hi everyone! I found this claw while anthill hunting on the White River formation of northeastern Colorado. It's about 6 mm in length and 4 mm tall. Honestly I'm not certain that it's a fossil, but if it is I'm really excited to have found it. My first guess is that it's a small bird, but it could very well be mammalian or reptilian. Any input is appreciated.

Help with some micro-gastropods from the Middle Jurassic of the UK
IsaacTheFossilMan posted a topic in Fossil ID
Hey all! Today I bring you some teeny tiny gastropods! All Inferior Oolite Group, Cotswolds UK. Every formation. There are a few different species that I have described here: Species A: "helter-skelter". A very very loose spiral, resembling a helter skelter... Species B: very neat loose spiraled. Species C: very tight spiral, very common Species D: fascinatingly bumpy textured spiral. Reminds me of a wallpaper! Measurements in cm. Isaac
