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" b

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 frac

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 sha

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!

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.

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. Gast

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. Ther

From the album: Aurora/Lee Creek Mine Micro Matrix
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

Hunting From Home - Texas Pennsylvanian (Bridgeport) Matrix
JamieLynn posted a topic in Fossil Hunting Trips
While I have been out fossil hunting a bit in the Texas Summertime heat I am still having great fun with the Micro Matrix- it sure is pleasant to sit in the AC and poke about for fossils! I had some great little finds in the Mineral Wells matrix, but i am just amazed by the Bridgeport matrix. Even though it's still Pennsylvanian, it's very different from the MIneral Wells stuff! Different formations and all..... What's really neat about the Bridgeport matrix is firstly - it's bigger, typically. and secondly...it's COLORFUL! Reds and golds and purply browns and oranges. It's really lovely st- 10 replies

Micro Fossil From Conglomerate Found in East Central FL
timhigg posted a topic in Micro-paleontology
I picked up a nice chunk of conglomerate that had an obvious fossil tooth embedded in it, but became interested in what small micro fossils might be in it. I experimented with a small piece of fossil bearing rock and found that the acid destroyed the fossils amost as much as the rock, so as a result I turned to just doing surface scans. I eventually decided to remove one surface micro fossil that seemed to be pretty much on the surface of the conglomerate. The results were satsifactory, but I don't know what the micro fossil is. It is roughly one mm in diameter and maybe half a mm thick- 4 replies

Good morning. Is there an accepted demarcation of what constitutes a micro? Is it 1/4 inch or smaller? These two Crows are 5/16 inches. The other photo is, I think, just a cusp which is 1/8 inch. Thanks all.

I hesitate to post this because I know next to nothing and don't know if it is worth posting, but I picked up what I would call a conglomerate one day on a Florida beach near Jensen Florida primarily because of a fossil tooth that was in the conglomerate. I could see a few other bits of bone as well. But I got to looking at the conglomerate with my microscope and saw what I thought were some nice small but interesting things. I suspect that the conglomerate is not very old and don't think there is likely anything much older than the tooth in the conglomerate except possibly some small shel

I found this small specimen while splitting some Pennsylvanian black shale today. As usual, I'm not sure what it is. Looks like a jaw to me but I really don't know. It measures about 5mm long. Any thoughts? @jdp @RCFossils @deutscheben

I was given this very small piece of ?mandibular bone. Any help would be appreciated in id. it is approximately 12-14 mm in length, 4 mm in height and maybe 2 mm on the dental surface from the hells creek formation in montana.

Hi. Found some neat stuff in the Lee Creek Matrix today. I believe most of it is fish/skate teeth. If anyone get help with ID it would be much appreciated. Everything is 1 - 2mm. Also, Can somone explain how to get of the dirt on these teeth? I soaked them in hot water and some of it came off. They are so tiny to scrub. What would be safe to soak them in? Thank you for any feedback! I believe these two teeth are Rhynchobatus Teeth #1 #2 #3 I think this is some type of skate tooth but not sure what type #4 absolutely no c
