Micro fossils seem to provide a lot of opportunities to experience pareidolia. I find the need to temper my excitement. Though, this gastropod fragment provided more laughs than excitement. My granddaughter will keep this one, after all she once had her own pet baby dragon.

This measures just under 1mm. Ostracod?

Ancient Bones has been searching a box of matrix from the Aurora Mine spoil pile in North Carolina and found this specimen. She sends her finds to me for photographing, but we are not sure how to label this one. My first thought is fish teeth in a fragment of jawbone. We are hoping that someone will be able to pin it down. @Al Dente @MarcoSr Thanks for looking.

Hi everyone! I came across this little piece as I was sorting through some of the anthill matrix I brought back from Wyoming's Lance formation. When I first found it, I must not have recognized it as a partial claw as it ended up alongside other odds and ends (fragments of bone, gar scales & other misc. fossils) at the bottom of a pill bottle where I had deposited all of my pickings. This week, however, I emptied that pill bottle to see what was inside in order to organize all the micros I found from this locality (which will get its own post eventually). It's evident to me that this is a claw given it's pair of blood grooves, but it's far and away the smallest in my collection thus far at only 3 mm in length and 2 mm wide. I'm sure it may be a long shot for a definitive ID, but I wanted to see what opinions you all had. And for what it's worth, the flat base and lack of curvature makes it look similar to my ornithomimid claw from the Judith River. These next two focused more on the forceps than the claw unfortunately, will retake these soon.

A few more of my favorite finds from the Aurora Fossil Museum Matrix - I am not even half way through the two gallon bags of matrix from my purchase! SO MUCH COOL LITTLE STUFF!! Being micros, all specimens are under 1/4 inch Shark Teeth: Top Cookie Cutter, Sand Tiger Bottom : Catshark, Unknown Not Shark Teeth: Top: Not sure what this one is, Second one is Raja Bottom: Fish Porgy and Dasyatidae Top: Echinoid spine and tubercle Bottom: Burrfish mouthplate and a bit o' Crab I think Not sure about these but I am leaning towards Turtle on both top and bottom specimens.

I was looking through some of the rocks I have collected over the years and came across this one, appears to be an ordinary rock but with a strange fracture, it doesn’t look like a rock that would hold a fossil and the shape doesn’t remind me of anything which is why I’m pretty sure it is just a crack in the rock but I thought it odd that it was symmetric, since I am not 100% sure it’s a rock I thought I’d ask here scale is in mm, about 5 mm long first image shows the whole rock 2nd image shows another view of the rock 3rd image shows the fracture with scale 4th shows fracture from a different angle

Cabin fever made me stupidly ignore the weatherman (another institution I no longer trust) and head out into the 100% chance of rain and cold. Tried to avoid getting wet, as it WAS cold. Tried a very old spot, and was surprised at the results (the beach where I normally hunt has lost all its sand (?) and I've found no teeth their my last three trips). No rain, Birds were uproariously singing, Spring on the way! The creek was high and icy, saw no aquatic life. Anyway, found a bunch, showing the most interesting. Although big makos are nice (and I like the piebald one better though the 2" black one is nice!), I'm always excited by the little ones (which is a good thing, since mostly what i find)-- four angel shark, a couple broken cowshark and symphyseal/ parasymphyseal sand tiger tooth, and lots of drum teeth (turned one on the side as it apparently still has the attachment as well as the glossy "cap"):

Got a new "toy" for my birthday! I was wanting an "upgrade" from my Celestron (which has been quite good - but was a little lacking in some respects) and thanks to the FF members input, I decided to go with the Hayear 14 MP HDMI microscope camera. It was just over twice the price of the Celestron but is much higher resolution (and much easier to capture multiple focus images for stacking). I still like the Celestron for my "picking through matrix" - but I am super excited about getting some better, higher res pics! Interestingly, in comparison, some of the Celestron pics are still better sharpness than the Hayear! And, the Hayear will only go as large as 1/2 inch so anything bigger than that and I will go back to the Celestron. So I will continue to compare and contrast. hahahhh!! Here are a couple of photos of some of my littles that I am pleased with how they came out! Central Texas Cretaceous This starfish Madreporite is right at the upper edge of size - It is 12mm and there was about 1 mm space on either side A 9mm Crab Claw Pagurus banderiensis a 4 mm Crinoid Isocrinus annulatus Aurora North Carolina Cretaceous A little Cat Shark 4mm An Echinoid Tubercle 3 mm A Ray tooth or dermal? 3mm Some Fish Verts 3 mm

Finally getting around to posting some of my New York Devonian Penn Dixie matrix finds! So much neat crinoid stuff, the occasional trilo bit and some other goodies! Someday, I hope to visit and maybe find some "Big" stuff! The CRINOIDS.....so many amazing shapes. I love Crinoid Geometry: (all are around 2-5 mm) The Trilo Bits: (2-5mm) probably Eldredgeops A friend was trying to type in Pygidium and it auto corrected to Pudgy Idiom.....so yeah. That's what they are now. Plus this nice sized one (5mm) in situ with a crinoid! Gastropods Naticonema lineata Size 5 mm Platyceras size 3 mm also maybe Platyceras? 2mm And some other neat things: Tentaculites Size 7mm Coral Amplexiphylum hamiltoniae Size 2 cm and Bryozoan Reptaria Size 3mm which I think this is also? 5 mm

I have a quick question for those that have bought and gone through their micro matrix from the Aurora Fossil Museum. Did you wash it before going through it, or wash it after you've found your fossils? I got the pack with the mini screen for sifting, but I'm a little afraid to wash it all first and risk losing tiny teeth. How did you all go about doing yours, or what do you think the best way would be?

I found these on a beach in Illinois in a small lens of pyritic sand. I believe they are worm tubes but not entirely sure. They are only visible under microscope and occur with pyrite framboids. So my question is, are they indeed worm tubes, pellets, or something else? I can only assume they occur at the beach because of erosion of Silurian rocks placed there, but not sure of that either. In this pic below, you can see partially inside the tube which features spheres of pyrite. It's my understanding can be produced by worms. framboid Thanks for any help!

I bought this cleonaceras ammonite a while ago. It’s 110 Million years old from Madagascar. It said it was filled with mud and when I was looking at it I saw many small fossils, some of these may be unidentifiable or even not fossils but I know some are and want to see if you guys can help narrow it down. Since they have been polished the inclusions on one side are not on the other here’s the ammonite, 6.9 inches the longest way 1. Gastropod? 2. Shell fragment? 3. Shell fragment? 4. Gastropod? 5. Gastropod? 6. I know this ones a gastropod, anything else? 7. Shell fragment? 8. No clue, probably not a fossil 9. Tiny gastropod?

In October 2020 I went to Watton Cliff for my first foray into microfossil hunting. I have since dissolved some of the matrix I collected in 20% acetic acid and one of the things I found, amongst all of the crinoid pieces is this. I'm not sure what it is but I'm guessing it's part of a fish. Are the rings visible on the reverse side annual growth rings? The sample I collected from Watton Cliff is from a loose sandy layer within the Forest Marble and is Bathonian in age. Thanks for giving it a look, as I sort and take more pictures I may post more of what I've found. There is so much crinoid material its difficult to separate it all from the sand. Benton

This assemblage came from one cup (about 340 ml) of micro matrix from Aurora Fossil Museum. Oddly, they are generally much larger than most of what I found in the rest of the matrix. They are all from either the Pliocene or Pleistocene. See album description. -

This is a completely new area of interest for me, but I find scanning for microfossils addictive. I got some vinegar and plan on processing some beach rocks (East Central Florida) that I picked up because I could see easily see some small fossils on the surface and assumed there would also be micro fossils inside. I crushed a few small samples, which did reveal more microfossils. Mostly what I could identify are broken bits of bones, but I'm sure there is much more that I'm missing. There is one object I found very interesting and beautiful, however I don't know what it is. I would like to know what you think the first object might be. That object is still attached to the matrix. The other object I found in the same sample. Both were revealed after breaking the sample. The first item is about 1/8th inch long but very narrow, and from some angles appears to be a hollow tube. The next object appears to be bone and is only about 2.5 mm wide and long. Thanks.
