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.

I love collecting Devonian corals. No two are exactly alike and some like this specimen are much rarer then the most collectible fossil (complete trilobites from any period) from New York. Confluens is a highly sought after coral species. Only found in a very limited area. I find one colony for every 500 solitary Heliophyllum halli and only one colony in ten is complete like this specimen. That's why this piece had to be prepped. Well preserved epibionts can be seen in great detail thanks to the meticulous prep job. Heliophyllum halli confluens (Hall, 1877) Middle Devonian colonial rugose coral 88mm x 71mm x 60mm. Found 9/12/2018 in Livingston County, New York. Found - Mikeymig, Prep - Malcolm T. BEFORE AND AFTER PREP PICTURES

I have a mostly complete trilobite that I found this summer at Paulding, Ohio (SIlica Fm, Devonian) which I had assumed was a Pseudodechenella lucasensis, partly because it looks like one and that was the only species of Pseudodechenella that I was familiar with from the Silica (granted, I'm no expert, I've just done some reading). But in looking at this specimen a bit closer and reading a few of the articles, particularly Stumm's 1965 description of the species, I'm having some doubt on the ID and want to solicit the opinion of the Forum. I know there are several Devonian trilobite enthusiasts out there and I would appreciate your thoughts. The primary feature that has me questioning the ID is the lack of a medial groove on the brim of the cephalon which according to Stumm is supposed to be one of the diagnostic features. I don't see one on this specimen, but could that be a matter of preservation, growth stage, or just variability within the species? I have seen that P. alpenensis is also found in the Silica Fm. but that appears to have a much wider brim that what this specimen has (about 1mm wide). There are plenty of other species of Pseudodechenella from other areas of the same age and I have looked at lots of pictures, but not picked an obvious match. Stumm made a comparison to P. rowi, but I am not aware of this species being found in the Silica Fm. I am working on gathering the descriptions of these various species so I can see if that helps me, but I thought I'd see what some of you thought. Any ideas are welcome, thanks. The scale is mm's, it is about 19mm long.

This is my fossil collection please show us yours!!! These are my display fossils only The first picture is a large unidentified fossil shark tooth I recently bought from a local fossil store. The second is my display collection I put fossils in once they have been prepared or bought. The next photo is Madagascar copal it is about 9 million years old and it has multiple inclusions including fly's, wasps, and spiders. The next is an unidentified fish fossil in good shape but not too valuable. The fifth fossil is a trilobite (paralejurus) in Devonian limestone it is 385 million years old and was found in morocco I know the most about this one. And last but not least is my small polished chunk of Baltic amber it is 35-50 million years old and contains a winged insect inclusion as you probably know amber is fossilised tree resin and copal is hardened tree resin that is not quite fossilised. Thanks, HAPPY HUNTING!!!!!!!

The title explains it but for a little more prepping or starting prep need to know roughly what it is before I can be comfortable in my work appears to have a rather odd placed general spine on the right and the head is not shaped like a holladrops. Thanks in advance Matt

Loriolaster mirabilis Stuertz, 1886 Early Devonian Early Emsian Bundenbach Quarry Eschenbach Germany Diameter 8cm -
Back at the end of June at our spot in the Thedford area a small group of us were busy making benches and unlocking slabs from the Widder Formation. Once we got to splitting, one lucky split resulted in finding three Greenops widderensis on a single plate. With flying genal spines and lappets on an already delicate and thin-skinned species, it was nothing short of miraculous that I was able to get it to the car with no damage. Right away I applied cyanoacrylate, and then it started to rain. This is how it looked in the field:

I was on a quarry hunt with our fossil club yesterday and noticed this 1 cm. specimen in a sandy/ shaley rock that had scattered cinoidal fragments in it. No one could ID it, so I am offering it up to the experts here on the forum to tell me what it is before I attempt prepping it. The quarry is Devonian, but I can not tell you more than that since this was found in a heap of stones, not from the wall itself. thanks, Mike

Yesterday I was in New Jersery for my son, Dylan's marching band competition. We had half the day free until they were playing at Rutgers stadium so we met up with @frankh8147 to hunt one of the Cretaceous streams. We met up around 9am and it was raining. Not a torrential downpour, but enough to soak into your clothes even with a raincoat. I wasn't deterred and neither was Frank. Heck it didn't seem to bother him at all. I would like to say Thanks to Frank for being a great host and guide to me and my family. He has such a great wealth of knowledge of the fossils from that area. Plus this was the second time since July that he was willing to meet up with us. It didn't take long to start finding fossils. Right off the bat frank found a cephalic clasper from a shark! It was a decent size and condition. I found mostly shark and fish teeth. Frank seemed to find more of an assortment including reptile. He gifted Devin a Goblin sharktooth, and myself a partial mosasaur. Sot of a highlight for me is what maybe my first point. I say maybe because frank wasn't 100% sure because it is quite worn but said he has seen similar pieces which after being looked into were in fact points. The key is to find out if the object is made of argonite. An old tribe used argonite for their points and does not occur naturally in N.J. Anyways we stayed about 4hrs before we had to part ways but it was a great time with a great guy. Thanks again Frank for everything, including the pieces you gave me before the hunt. Hope you like the New York trilos. ( Don't forget to get me the info of those pieces) Here are pics of the gifts and finds.

Although the most pieces of my collection are goniatites, I am more than happy to add other Devonian cephalopods to my collection from time to time. On my last field trip for devonian cephalopods I splitted a few nodules and some of them had a few uncommon fossils in them: Bactrites I rarely find decent fragments of them, but those few were looking promising. Bactrites, although they look like an orthocone are in fact straight Ammonoids and not a Nautiloid. the septas start to be slightly ondulated, but most important they have a ventral siphuncle, a typical trait of an Ammonoid. the first nodule had a fragment sticking out, and when I split the nodule another one was found inside. I kept both parts of the nodule and prepped the one inside and on top After prepping them I found out that neither of those were complete, but the were decent in size and well preserved. The second nodule on the other hand hand was much better, a piece of the Bactrites was sticking out from both ends of the nodule, so I new I had a complete specimen. The prepping was relatively hard as different parts of the cone had different forms of preservation, but in the end I got the whole specimen out of the matrix and is my best Bactrites until now. enjoythe pictures: 1st nodule with the specimen inside: after prepp: After prep with the top of the nodule containing an other fragment. prepp on the 2nd nodule: after prepp, with the different kinds of preservation visible: and the whole lot:

I’ve decided to change my Avatar, which I’ve kept since I joined TFF, but I wanted to send it off with a little information about it Zoophycos is trace fossil found around the world from the Lower Cambrian till present. It is either a feeding trace thought to be from polychaete worms. I had the chance to see and photograph it on my second fossil hunt, about a year and a half ago now. It was found at a site in the Devonian Mahantango formation of Maryland. I couldn’t remove it then, and it was gone the next trip. The other worm burrows were what lead me here in the first place, so I thought it was fitting it would be my avatar for a while. Here it is:

Another fun trip to the Montour Fossil Pit Yesterday
MeisTravis posted a topic in Fossil Hunting Trips
Had another successful trip yesterday to Montour. It’s only my second time going but I really enjoy this place. Figured I’d share my finds with all of you! Partial stem? Clam that was still in the rock, this one actually was nice compared to what I normally find 4 small Pleurodictyum I found, top right is still pretty well encased A really nice shell, possibly oyster?

Found this today, I used to call these coral but I think they're actually bryozoa. Am I correct? Sorry I forgot scale its about 1.5 by 2 inches.

Dear friends, I need your help on identification of a fossil that I found in the Carpatho-Balkanides of Eastern Serbia. The fossil was found in a quarry of Upper Devonian turbiditic, fine to coarse grained siliciclastic sediments. Shales which bear the fossil are a top part of a complete Bouma sequence. This is maybe indication that the fossil was not transported by the turbiditic currents but was buried by sediment vertically from the water column. Late Devonian (Fameniann) age of the sediments is based on Cyclostigma remains which are wide spread in certain levels of turbidites throughout the quarry. It was a single piece broken in two. Basically the shape represents a concave and convex pair. Note the dark outline following the shape. I thought it was some ichnofossil. Outlines are often found on the surfaces of shales in the quarry. Thanks for your time and hello from Serbia!
