From the album: Fossildude's Middle Devonian Hamilton Group Fossils
Small plate with an Eldredgeops rana cephalon, crinoid stem/columnals, ostracods, and a Platyceras sp gastropod. Middle Devonian Hamilton Group, Smoke Creek, near West Seneca, NY. -
Hello everyone, Recently @Shamalama showed me great kindness and generosity when he sent me some samples of matrix from three Devonian sites. This package arrived yesterday and I have slowly been picking out all of the tiny fossils. I want to use this topic to show off my finds. Here is everything I received:

How to properly dissolve matrix to reveal microfossils? Tips & tricks needed
ziggycardon posted a topic in Micro-paleontology
Hi, a few days ago I went on my first ever fossil hunting trip to Eben-Emael, a Limestone quarry in Belgium that dates to the Maastrichtian and is part from the type location (the historical ENCI quarry being only a 3,5 km to the north. The trip was orginized by the BVP (Belgische Vereniging voor Paleontologie) and a short report of the trip with phot's and some of the finds can be found in this topic by @Manticocerasman who I was lucky enough to tag along with, cause I doubt I would have found many mention worthy fossils without the guidance of Kevin. But since I am- 4 replies

Trading Jurassic Ostracods from Connecticut
Misha posted a topic in Member Fossil Trades Bulletin Board
Hello all, I have recently acquired more fossilised Ostracods from here in Connecticut. All of them are very different from each other and some come in plates as hash while others are more scattered but also whole. The plates range in sizes but the ostracods are pretty much the same everywhere. Some plates also have clam shrimp. These do not seem like particularly rare pieces although I have not seen any others from the Jurassic of CT. In return I am mostly looking for any Paleozoic material but I am open to any suggestions. Thank you everyone, More pic -
Here I have a few hash plates littered with ostracods all over their surfaces, they don't show up great on camera but I will also include a closeup shot of the surface. They were all found by me here in the Jurassic shales of Connecticut. I have way too many to keep even from just one batch of matrix but feel bad throwing them away. I am not looking for anything in particular just seeing if people would be interested, Thank you all, Misha.

Due to the current instability of the cliffs, I headed west Sunday. @EMP helped me out with a ton of info, so I knew I could hit a few sites in one day. My dad and I drove to Allegany County and got to Hunting. I messed up the directions so probably didn’t get to the exact site, but I found a few exposures of mid-late Silurian material, probably McKenzie and Tonoloway formations mostly. The yield was a huge amount of ostracods, some brachiopods. My dad saw a strange rock so I climbed some talus and picked it up. Upon closer examination it had not only ostracods, but tentaculitids on it! Think

Found this piece of large (for the location) orthocone yesterday in a Brigantian (Mississippian) mudstone. The thin bits of surviving shell are apparently pierced through with many small round objects, mostly circular, 0.3 - 0.5 mm in diameter. Each one is now a very low cylinder (like a watch battery) with apparently vertical sides and depressed centre. Many are filled with pyrite. They have left impressions on the mudstone internal mould - the whole shell fossil is covered with them, both the living chamber and chambered phragmocone. Ostracods came to mind b

Hello all. I have been really stumped on these for a long time. They look like small bivalves at first site, but they have odd shapes and some have a long, straight "hinge line"; none have a clear umbo or ornamentation or internal detail. I wonder if they could be ostracods? I found them at an outcrop near Catskill, NY, at a place where you can see the Taconic Unconformity. Specimen came from a big slab of rock detached from the outcrop, and I could not find where it came from. So it's age could be late silurian or middle ordovician. In the microscope, I can tell it's definitely a shell materi

This is just a guide to people who want to collect microfossils and don't want to spend a lot of money. This topic includes foraminifera,conodonts,ostracods,scolecodonts,and misc. mini fossils mainly too small to see without magnification. It will not be all encompassing, mostly for the beginners. A) Collecting; If you happen to live in an area that has a lot of shale/clay then you are in luck. The Ordovician and the Devonian both have lots of microfossils. Just gather up a bag of clay from between the rock layers. Soak the clay in a big bowl , crush it up with your hands, and slowly decant th

I've been experimenting with breaking down some Windom Shale from Penn-Dixie, and I think I have some ostracods: I have a few other interesting bits, too. Are these echinoid spines, micro-belemnite bits, or something else? And then there's this object: That's a small sampling. I also have found lots of brachiopod pieces, which is not surprising. The shale is rich in macrofossils, especially brachiopods, trilobites, horn corals, and occasional straight cephalopods.

So I have found a couple more ostracod pieces. Sadly small pieces and very fragile.... The loupes I ordered came in the mail so tried to snap a couple shots, starting with my original pieces (have positive and negative). This isn't a great pic and hoping to get better ones tomorrow. It is through a 5x loupe. Will add future ostracod pics to this post!

Now that there is a microfossils subforum, I thought I might gather various posts regarding some silicified micros I found recently.... Years ago, I collected a few nice gastropods that were silicified: Because they came from limestone, I figured I could extract many more with muriatic acid. Last summer, I collected some chunks of rock that contained the mollusks: This was the result of the acid bath: There weren't as many snails as I'd hoped, but I was intrigued by the fine detritus. Time to pull out the microscope.

Part 2 Fossil mounts cont. I cut the ID lables to fit the coin holder I am going to use and glue it in the box using a glue stick. Let the glue dry, and coat the numbered area of the lable with a 50/50 mixture of white glue and water. Do not put it on thick, a thin coating will do. When this dries the holders will be ready to use. The blank area at the top is for location information. E) Magnifiers: You can use a hand lens of 20x to view the prepared sample but this will get real tedious if you are doing much looking. There are several other relatively cheap options.
