Hello everyone, I have been interested in fossil fishes from the Ordovician- Devonian for quite a while now, and recently I have begun to venture into the field of micropalaeontology a bit more. This has led me to purchase matrix samples from the Harding sandstone and I am also interested in getting some Maple Mill stuff. The problem is I currently only have one more vacant slide to use for these fossils, it was sent to me by @Shamalama with some other microfossils but I don't know where I could get more. The slide has an aluminum case with a piece of thin foam board inside and a glass on top. The foam board has cutout with a grind going from 1 to 64. I was wondering if anyone else might know where I could get some of these as I have not been successful in tracking them down myself. Thank you, Misha

I was lucky enough to receive some Micromatrix from @Gizmo and @sharkdoctor, and today I was looking through some of the teeth when I saw one I hadn’t noticed before. I’m sure I’ve seen something like it onlin but I can’t for the life of me remember where or what it is. Any one got any ideas? Matrix is from VA, Old Church FM (oligocene) and Calvert FM (Miocene) contact layer. Measure is in centimeters

Hi all, Need some help with this ID! I found this fossil years ago on a beach in eastern North Carolina and it's been a mystery to me since. The best answer I could come up with is that these might be some kind of foraminifera (maybe of the fusulinid variety, though these don't seem to have the tapering at either end), but I'm not sure how to go about researching other possibilities. My camera has a tough time with close-up pics, so this is probably as much resolution as I can get. Thanks in advance for the help!

Hello all, I believe that one of these is a foraminifera, not too sure if that tiny bivalve and snail would be considered one or not. Anyone have any ideal what period these may be from? Was digging some old bivalves and gastropods out of some sandstone and came across a boulder that had hundreds of microfossils mixed in it's debris. The size range from what you see here to less than 0.50mm. Some if this stuff is really cool looking.

Fossil Hunting From The Safety Of Your Home
Mioplosus_Lover24 posted a topic in Fossil Hunting Trips
With the current pandemic I decided now was as good of a time as any to get some matrix from the Aguja Formation with the help of PaleoTex! This turned out to be a great decision as I was extremely lucky, finding about basically everything I wanted to, and more in only 5 pounds of matrix! I'll be sure to post pictures but I got numerous amia and gar teeth, along with atleast 36 gar scales. Tons of Crocodile teeth including a large Deinosuchus tooth. Several shark teeth and a partial hybodus spine, also several brackish water pycnodontid teeth and tooth pallets. 4 fish or salamander jaws with teeth. Regarding dinosaur teeth I got 17 Hadrosaur teeth, including 2 partially rooted. A partial Ankylosaurus tooth. 4 Therapod teeth including a perfect Saurornitholestes tooth and a Premax. My favorite find however was the Paronychodon tooth I found! I'll be posting that picture first! Highly recommend this matrix, but I was also told that most people don't find all this stuff, so keep that in mind aswell. Stay safe! Happy hunting!

So...while splitting my thousandths shale and looking under the scope, I came across this organism, which appears to have interdigitating teeth?. At least most look interdigitating as opposed? Or , I just dunno. There is also a surrounding imprint on both sides. It was found in Stark shale Kansas City Missouri and is nearly 2mm long. I have two views, and can get the other split side, but this is the best images so far.....ANY thoughts, would be appreciated!....In my very limited (one month :)) experience looking at conodonts, this doesn't appear to be one, (S elements?) but, I've been wrong so many times on other fossils,, this would be a breakthrough:)…. Thanks for looking! Bone

I’m hoping someone on here has some spare matrix from the Mississippian Golconda Fm in southern Illinois. The roadcuts near Anna and Vienna are pretty well known (I know a few members here have hunted there), but at over 6 hours away it’s a bit too long of a trek for me right now. A recent paper on microfossils from there piqued my interest and I’d like to try and process matrix to search for some. If you have any, PM me and we can work something out.

I had a few duds pop open yesterday but saw one had a tiny speck of something on it, no more than a millimeter long. I had my digital microscope out for other microfossiling activities and decided to take a look. Nothing super interesting, just a tiny plant fragment. But it did get me curious if anyone has done micropaleontology work on Mazon Creek material? I would think there would be quite a bit to explore, but that said I've never really seen the topic mentioned. The only microfossil I've seen discussed from Mazon Creek is a species of ostracod, but usually the only specimens you see are nodules containing hundreds of ostracods as they are readily apparent to the naked eye in that case.

I have shown several of these things to a number of micro-paleontologist, paleontologist, geologist and marine biologist and no one seems to know for sure what these specimen are. They were found in a sandstone boulder with bivalves fossils, they range in size from about 3mm to about 0.20mm. I'm told that they are most likely a new foraminifera species. Anyone have a clue???

The first specimen is about 0.70mm long and the last one has a diameter of 1.4mm. I searched all 166 pages at marinespecies.org and came of two look-a-likes for the first specimen, they were, triloculina and quinqueloculina. The last specimen sorta looks like something named reophax subfusiformis. I can't say for sure if those are the correct species for these but it's a place to start. I've come across hundreds of these things and to date only about 3 can be identified by scientist.

Hi all, I just got the studio equipped with a digital microscope, and I've been enjoying looking through the sediments of fossil prep work. I'm finding a lot of micro crystals, and other forms that seem like pollen, or microscopic life I also found 2 insects, which I'm not sure of their origin, they could be contamination from the room, but I'm fairly certain this batch came from caked-on sediments at the bottom of my sample container.

I really like the shape to these. I have come across sites with photos of these but I can't seem to find any info about them such as what period they may be from. These microfossils are harder to research than they are to find...phewww.

Hi folks, we bought a sample of microfossils originated from Waurika, Oklahoma. It was really fun to search through the little pile and try to ID the pieces. The result was a short video We decided to share it hoping for comments and more interesting info from the knowledgeable audience of this forum. What's really cool about microfossils is the amount of details and often stunning preservation of tiny pieces. Does anybody know a microfossil locality in Central California?

Hi all. Only one of my first few posts on here as I'm primarily a collector. However, this would tie two of my hobbies together. Microscopy and fossils! I've gone through the pinned articles on prepping, cleaning, etc. The one thing I'm still not clear on is retrieval of the matrix as easy as digging a shovel full of dirt, running it through sieves, sorting, and hunting? I'm currently living in Biloxi, MS, so I assume I'll need to travel an hour or two to get out of the marine deposit area that is constantly in and out. Thanks so much! -C
