Fossil Insects from the Eocene Florissant Fossil Beds (Teller Co, Colorado)
Opabinia Blues posted a topic in General Fossil Discussion
Being a Colorado native, I have taken multiple trips to the public-access Florissant Fossil Quarry located near Florissant Fossil Beds National Monument in Florissant, Teller County, Colorado. This quarry provides fossil collectors fantastic access to the shale layers of the Florissant Formation, a late Eocene (Priabonian, ~34 million years old give or take) lagerstatte known for its diverse fauna of fossil insects, in addition to plants, gastropods, and very rarely vertebrates. Most fossils occur in very thinly laminated ashy grey shales. Other lithologies present include well-sorted tan cour- 8 replies

I'm interested in looking at the internal structure of fossils. I would like to try my hand at making thin sections. I found this protocol: Making thin sections by hand It looks feasible. I have microscopes and I'm willing to invest in some equipment as necessary. I would really appreciate hearing from anyone here who has made thin sections who could help me get started. Thanks Roger

So, I'm a bit conflicted. Part of me wants to call my specimen microfossils, yet another calls them macrofossils. Some definitions state the boundary as "being able to see the fossil with the naked eye", other state it as "being able to see the details of the fossil with the naked eye", and yet others state it as "being able to see the fossil with the naked eye or low-powered microscopes". On this forum the prefix "micro" is thrown - for want of a better word - around a lot, even when it disobeys official definitions (which are still incredibly ambiguous!). What do you

I just recently came across a very helpful website: https://www.microbehunter.com/microscopy-forum It is a friendly site, and I’ve gotten quick replies to some very specific questions about a vintage microscope I recently acquired. There are a number of forums, including one for people looking to buy/sell parts. Some of the folks there have some pretty obscure old microscope parts if you ever find yourself in need of some. They’re also good for advice on how to setup and optimize your microscope.

Dive Into an Ordovician Ocean—Trilobites—And a Rare Find
FossilSniper posted a topic in Fossil Hunting Trips
On July 1st, 2021, I went for the first time to a public, personal site and was very pleased with the results of my fossil excursion. The locale consists of several exposed formations, namely the Liberty formation I was hunting in. In my region of southwestern Ohio, that's known to be one of the best fossil-hunting formations due to its remarkable preservation of particularly fragile Ordovician life, even when compared to the excellent fossil preservation quality of other formations in the area. The thirty-three degrees Celsius heat was rather hot by itself, and as the sun's rays- 4 replies

Hi everyone, I have been collecting fossils for some time, but this is my first post in the forum. I've recently acquired a stromatolite slab from the Strelley Pool formation. I have access to a laboratory compound microscope, and I was wondering if there is anything interesting that can be seen under magnification. I understand that I probably won't be able to see microfossils of any sort in this magnification, but I'm just wondering whether there are any interesting/discernible structures. I have an image that I took via this microscope att

So I make slides of microfossils from ~ <1mm - 2mm. I use a glue that I make with food grade gum tragacanth and water as was recommended to me when I first started. However, I have always found it a bit annoying to make, get the consistency right and keep properly, especially as I haven't been able to find any definitive guides to this. I'm wondering whether any of you use gum tragacanth as well and have a ratio/recipe/advice for me? Or if anyone has had good success (long lasting, dries clear, secure, fossil safe) with any other type of glue? Thanks!

I bought a pack of dinosaur bone rubble ( Sauropod allegedly) to make up the min price on a order of rock. Polished up a bit on my flat lap and did a fluorescence scan just on the endogenous fluorescence. Turns out to glow all over the shop and makes a great test slide . The microscope tracks a laser spot across the sample and measures the fluorescence produced at whatever wavelengths you set. The first image is one frame at higher res, the field of view is about 60 microns. but I was testing the frame stitching so the second image is a tiled scan - same res. The original files are 3d too tho

Hi! I recently acquired a bunch of microfossil samples for kids to play but did not expect them to be so small. We tried some microscopy but ended up applying a little trick that actually to helped to film them "in action", which was kind of cool. I do not know if this technique is a common knowledge or not but I decided to share. Perhaps, it will be of use to somebody. Here you go: Any suggestions for improvements? Thanks!

Hoping some of the pros here are willing to share microfossil prep techniques or suggestions to journal articles on the subject. I have been hunting conodonts and the like for quite some time, but the glacial acetic acid digestion and pan and scan techniques have failed me. I experimented with HCl and H2SO4 in various concentrations, and even tried some ion exchange extractions ( which work on paper, but are lousy in practice)! This sort of fossil hunting has become vendetta for me and I suspect I am using the wrong search terms in the academic data bases. I'll be

Looking for a Stereo Microscope in Europe
The Wellsite Geologist posted a topic in Micro-paleontology
Hi everyone! I'm looking to buy a Stereo Microscope in Europe for microfossil observation and was wondering if anyone can point out recommended brands. The price range for me is <400 Euros. Thanks! -
Thought I'd share this here. I just purchased a nifty device for aiding photography through the microscope with a cell phone. I shoot photos through the scope all the time, and if you have ever done this, you know that it takes surgeon's hands to find the eyepiece, center the photo, and get a crisp image. This device clamps to the eye-piece and works on monocular and binocular scopes. It adjusts for the placement of any cell phone. A bit pricey at $189 (available online at Scientific Device Laboratory), but I had to have it and already love it. Here's a pic without the p
