I found these items while working through the calcareous shale my wife and I collected from Paulding Ohio this summer. This material is primarily from the Devonian aged Silica Shale. I found one and didn't think too much about it, a fragment of fish/trilobite/shell or something else perhaps. Then I found a second which looked similar and so I did some prep and was able to expose more of each piece. These are small (those are mm's on the scale) with the biggest one being about 10mm by 12mm and the smaller one a little over half that size. They don't look like anything I'm familiar with nor could I find any matches in numerous books or online sites. I know the pictures are not ideal and they are embedded in the rock, so nothing from the side or underneath (first two pictures are the same one). They are very dark in color like much of the trilobite material. Oh snarge, it just dawned on me. Are these hypostomes? I don't think I have ever seen one before. Maybe I answered my own question, but I typed all this already so I'm going to post it just to make sure. Thanks, any ideas would be appreciated. Now I see a thread from 2011, so yes, these are hypostomes, but I'm uncertain on which species it is from. Looking for examples from Eldredgeops and Pseudodechenella since those seem to be the genera present in the Silica.

Here is a prep series of a tiny Pseudodechenella lucasensis from the Mid-Devonian Silica Shale that I found in Paulding, Ohio, yesterday. Not complete, but not a common find, so I am very happy with what I got. I'm probably going to restore this by sculpting the genal spines, etc. 1. Farm Fresh 2. Roughly exposed with pin vice. 3. More cleaning with pin vice. 4. Final product after air abrasion with dolomite. 5. This is a tiny one...

I spent the Holiday weekend in Port Clinton, Ohio visiting my relatives. On my drive to there, I made a slight detour so that I could visit the fossil site north of Paulding, Ohio. I must commend La Farge Quarry for their creation and upkeep of the park!!!!! They must, unlike most quarries, realize the treasures that lurk within their rock. The park consists of about 10 rows, 100 feet long of fossiliferous rock they provide for the public's enjoyment. Some of the piles are weathered and some are fresh. Certain species are better found in the weathered rock, others in the fresh. Look at both!! Here is a sampling of what can be found in a few hours of collecting: Brachiopods abound from small to large.

Another great hunt in Paulding, OH. Weather was windy, rainy, and cold, but neither the fossils nor the avid fossil hunter seemed to mind. Here are some of the finds. I have also begun a working species list for the site in the Ohio fossil sites subforum linked here: Paulding Species List

Here is a large brachiopod I found recently at Paulding, OH. Distinguishing Megastrophia from Stropheodonta titan can be difficult, but I think this one is S. titan due to its low profile. The side shown here is largely exposed, but the other side was covered in matrix. Unfortunately, this field photo is the only "before" photo I took. I decided to leave this one on a pedestal of matrix. The matrix was really sticky. The bulk would pop off with the scribe, but a thin layer clinged to the shell. So rather than scratch up the shell with a pin vice or take hours blasting it, I prepped this one chemically with KOH flakes. About 80% of the "prep" was done chemically. The Silica Shale is rich in organics, and the KOH turns the shale into mud. I made several applications on the thick areas of matrix. Final procedure included reversal of the base by a quick dip in 5% glacial acetic acid and then a good soak in water. Here's the result.

Hi. I've spent the winter reviewing my finds from 2017. Here are two images. Initially I thought the radiating arms were those of a brachiopod, but I'm now having my doubts. Could they be crinoid arms? (The specimen in the top image is on the upper left corner.) I failed to include a measurement scale, but the top specimen would be covered by a penny, and the bottom by a nickel. They're tiny. Thoughts? (Paulding, Ohio; Middle Devonian; Silica Shale)

This might be a job for @piranha This trilobit looks a little different to me than the typical Eldredgeops. Maybe Dechenella lucasensis? I didn't realize how poor the photo quality was until I cropped it. I can take more photos under the scope if necessary. Silica Shale, middle Devonian (Givetian), Paulding, Ohio. Scale in cm/mm. This one seemed different as well.

Is this what I think it is? A camera steinkern of an orthoconic nautiloid? This is from the middle-Devonian Silica Shale of Paulding, Ohio (although because it is quarry spoil, there is a possibility it could be the underlying Dundee Limestone). I don't think I've ever found an orthocone in the Silica Shale, let alone one this large. I hope this is not something that has been intentionally or unintentionally salted in from another site... That really burns me up.

Greetings All! I am Pam, I live and work in Toledo, Ohio where I teach biology and geology at the high school & collegiate level. I have a deep fascination with paleontology in general. However, I love studying and collecting in the Silica Shale Formation right here in northwest Ohio. Trilobites rule! I'm looking forward to chatting with all of you!

Hello, Found these interesting "fronds" in the Silica Shale on Sunday. My best guess at the moment is the bryozoan Reptaria stolonifera. Looking for confirmation or other suggestions. Hope these photos are sufficient. It was a tough one to photograph.

I was debating posting this under the Ohio fossil discussion but am passing through Ohio on my way out to Utah and wanted to know if anyone knows of any good spots to go to. I hear that there's a fossil park in Paulding with the famous Silica Shale trilobite layers. I have all the tools in the car and my wife said I could go out for about two hours tomorrow though it might be one with a cat and newborn.

Could this have been a calyx? Or just some slate shale? It pretty much crumbled when I tried to clean it. 1 inch round.
