I've been finding some interesting clam fragments at Paulding, Ohio (Silica Fm., Middle Devonian) with original shell and a conspicuous sharp angle along the dorsal side of the shells. They are coming from the limestone layers of the formation (not the shale). Finally, I got one complete enough that I might be able to get an ID. It's about 3/4 complete, but unfortunately it's missing the anterior end, including the umbo. I've tried to illustrate the shape via some photos with reconstructions (red line) of what's missing. It's hard to illustrate the 3D qualities with photos. I'm thinking this is Mytilarca cordata. Looking for confirmation from those familiar with clams of Silica Formation or other Devonian formations of same age. The shell (what remains of it) is about 6cm in length. @crinus

Hello Forum, I was vacationing in Kingston NY last weekend and went collecting along the Middle Devonian road cuts along route 209 and 9w. Hope the experts here can help me identify what I saw and collected! The first image is a fossil, too fragile to remove, in the 9w road cut that stood out from the masses of shells surrounding it. The rest are bulb like forms (corals?) collected from the loose shale of the Route 209 roadcut. Any ideas? Many thanks to the NY enthusiasts posting here that inspired my search. - Ben

The missus and I spent a good part of the day at our spot in the middle Devonian. I chopped out several large slabs while Deb split some of the smaller chunks and managed some overburden duty. The split in the wall may seem promising, but there are a lot of interlocking pieces that have to be removed in sequence, something like taking apart a jigsaw puzzle, but needing to locate the key stones first.

Hello fossil friends, Once again, I was in western New York for my annual 4th of July family get together. I was able to get out for a short hunt on July 5th, thanks to my wife and my cousin and her kids. I got up at 5:45 am, got on the road by 6:00 am, and traveled the hour to my usual spot of choice. I arrived to the site around 7:00 am. I have been coming here for many years, and I don't think I've ever not found something interesting there. I only hunted from 7:10 am til 11:20 am. I took a break to meet up with my cousin and her kids for a guided fossil hunt. Can't really hunt when being called hither and yon to check out the latest find. All in all, though, I didn't do too bad, for the short time I put in. First, few shots of the creek: I noticed some recent digging in this spot - I knew my friend JeffreyP had been here within the past few days. Unfortunately, I was not able to meet up with him this year at this site. I hoped he had left me some things to find! This is my total haul: Some brachiopods, some partial trilobites, a few gastropods, and some complete/mostly complete trilobites. Close ups to follow ...

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...

Brevicoceras casteri, with Hederella filiformis
Fossildude19 posted a gallery image in Members Gallery
From the album Middle Devonian Hamilton Group Fossils
Brevicoceras casteri, with an example of Hederella filiformis. According to their 2008 paper, "Morphologies and Affinities of Hederelloid "Bryozoans" ", Paul D. Taylor and Mark A. Wilson "... interpret hederelloids as colonial, phoronid-like invertebrates, with retractable lophophores." Thanks to Scott (piranha) for the paper listed above. Middle Devonian, Moscow Formation, Hamilton Group. Deep Springs Road, Lebanon, NY. Generously gifted to my by Darktooth (Dave)© © 2018 T. Jones

Hello all. This is a cephalopod that was found by Darktooth Dave on our last outing at Deep Springs Road. (Middle Devonian, Moscow Formation, Hamilton Group, Lebanon, NY. ) He kindly gifted me the slab this was in. While trying to break down the slab, as it was quite huge, (2ft by 2ft, by 3" thick) the darn thing popped out. No other pieces to remove, just the one. This is the first slightly coiled cephalopod of this type that I've seen from there, so I'm struggling with an ID. Not only that, but it has an encrusting example of Hederella filiformis on it. Ultra cool specimen! Thanks again, @Darktooth! I'm guessing this is either a Gomphoceras, or a Cyrtoceras? Anyone have any other thoughts, on genus/species? Thanks for any help, and for looking.

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.

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

UPDATE: This could be Murchisonia sp. which has been recorded from the underlying Dundee Limestone and deposited in the Ohio State University Museum of Biological Diversity. Hello, I found a rare conispiral gastropod steinkern in the middle Devonian (Givetian) Silica Shale of Paulding, Ohio, last week. It's the first strongly conispiral gastropod I've ever found in the Middle Devonian (let-alone the Silica Shale). I looked through the FUMMP online database as well as the "Strata and Megafossils of the Middle Devonian Silica Formation" published by FUMMP and couldn't find any taxa that looked like this. It has the general shape of Paleozygopleura known from the Hamilton Group of New York. Is anyone aware of a snail with this general morphology that has been reported from the Silica Shale? Scale in mm.

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.

First trip of the year today to the "Fossil Gardens" at Paulding, Ohio. This is quarry spoil of mid-Devonian age, Silica Formation. There was not a cloud in the sky, and temps were relatively warm at 43 deg. F. I was the only one there for most of the day, and it was extremely peaceful. What a great day. Here are pics of some of the finds. These are "farm fresh" and haven't even been washed yet, but I did take time to polish some horn corals and get some acetate peels (couldn't wait). A large Cystiphylloides rugose coral.

It sometimes pays to look over favosite corals , I found this scolecodont jaw attached to the bottom of a large one , it's roughly 1mm in size, middle Devonian,Hungry Hollow mb, Arkona,Ontario. I donated it to the Arkona Lions Museum And Information Centre In Arkona, Ontario
