I've got a backlog of a bunch of fossils from the Silurian of Gotland that I received in a lot that I have yet to assign an identification to. In order to not overwhelm the thread with too much stuff I'll only post a few for a start. Location: Gotland (more precise info not available) Age: Late Sheinwoodian/Early Homerian Formation: Unfortunately unknown. A lot of the fossils from the same lot that I identified are restricted to the Visby Beds, but that's hardly conclusive evidence. Fossil 1 This one is especially confusing to me. Is this a colonial rugose coral that's badly damaged and heavily encrusted by a bryozoan? Or is it actually several things glued together by a bryo? Fossil 2 Fossil 3 Fossil 4 Fossil 5

My annual excursion to visit my family which migrated to Kentucky years ago took place at the end of October into November, lasting two weeks. Of course, the planned trip took me in the vicinity of some excellent fossil bearing sediments and though quality time with family was the primary purpose, I did hope to add to my collection. All of the spots I visited were ones I've been to before; however, the first stop was a new one for me- Paulding, well known and documented on the Forum for its Middle Devonian marine fauna. I drove from the suburbs of New York City for almost eleven hours, raining most of the way, arriving at and spending the night at a hotel in Defiance, Ohio. Paulding was about fifteen minutes away. Drove there the following morning, It was a brisk forty degrees, mostly cloudy, but sunny at times. A TFF member I was supposed to hook up with there unfortunately had to bail last minute. A nearby quarry which exposes the famed Devonian Silica Shale had, years ago, stopped allowing collectors to hunt there. There was a big outcry and the quarry set up a fossil park dumping fossiliferous rock onto a property they owned which the public were free to collect from. Much of it is now overgrown and much of the rock has been reduced to gravel. However, there are still many fossiliferous chunks out there if one is willing to look.

September found me exploring a rock formation I had never encountered before, the Waldron Shale of Indiana. It was impressive, offering up many gems (fossils). This post is picture heavy but stay with me!!!!!! First up is a typical hash plate. I am usually attracted to hash plates but discovered only one came home with me. Next time It will be a priority to collect more! Next up are the brachiopods of the Waldron, many of which were identified by the help of Adam's Silurian post. He will likely have some corrections for me, which I will welcome! Most specimens contained a mineral crust that took some effort to remove. The results were worth the effort. The next brachiopod I labeled Homoeospira, but these were definitely wider than the ones above. Notice the two ribs in the sulcus on the next brachiopods: Only 1 rib in the sulcus on these: Atrypa was the most frequently found larger brachiopod: My guess is that these are some form of Stegerhynchus but are much smaller and very thin: Rugosa coral was an uncommon find for me. Favosites, on the other hand, were found frequently: This tiny favosite grew around a crinoid stem: As for Bryozoa, I picture this unique one. It grows around a piece of algae. The algae dies, leaving the bryozoan standing hollow! This is the only species of sponge found: Initially, my thoughts were that the next specimens were TINY horn coral. But after seeing specimens of Cornulites from the Waldron on line, my thoughts changed. I welcome opinions on this! While collecting, I did not know a cephalopod ended up in my bucket. It was tucked in some matrix saved for another fossil, only to be discovered when I broke apart the rock at home!! This happens to me quite often and is why my tendencies are to save the whole piece of matrix a fossil is in until I prep it at home. Surprises then can happen. The species of ceph eludes me as it does not match the ones mentioned existing in the Waldron Shale. Trilobites seem to be commonly found in the Waldron, so I was a bit disappointed not coming home with a complete bug. Next time!!!! For some reason, I found 4 loose eyes of Glyptambon and almost left them behind. But after they were cleaned, I am glad to have kept them. Platystoma are common gastropods found. If you look closely, the flat spirals are P niagarense and the raised spirals are P plebelum: This next gastropods, Strophostylus cyclostomus, are very tiny (4mm) and ornate. My favorite: P:yrite seemed to grow on all of the fossils and needed to be removed. But once in awhile, some beautiful crystals would show up! And in addition, an occasional geodized brachiopod would be found: I will finish this post in a few minutes!!!!!!!!!!!!!!! Crinoids left to come.

I'm looking for some help IDing this cephalopod fossil I collected from the Silurian (Racine Dolomite) of northern Illinois. The specimen is just a slice of the entire cephalopod unfortunately, so maybe it will be tough to ID. Any help either way is appreciated. @aek Come across anything like this before?

Large Platyostoma niagarense gastropods were plentiful in the Waldron Shale that I collected in this early Autumn. But these tiny gastropods kept showing up and I can not find their identity. In the first picture, a P. niagarense is the large specimen. The smaller gastropods next to it are what confuse me. Maybe they are just small Platyostomas. But subjectively, their spiral is higher. And their coloration is different.

While journeying back out to the Mississippi River, I decided to also stop along the Meramec River in St. Louis. There are exposures of Mississippian aged Warsaw Formation along the river. I passed one, and turned around quickly to try my chances at finding a nice crinoid calyx. There was a lot of rock exposed, but not much of it was fossiliferous. Much of the rock was caked in mud and thick dirt, which made finding anything difficult. After a few hours, I did finally manage to find something worthwhile. It was a nice Agaricocrinus crinoid calyx, exposed in the hard bedrock. Unfortunately, no amount of chipping or pounding was going to get this out of the hard bedrock. Luckily, I had a new grinder in my car I had purchased last week that came with a diamond tipped blade. I had never used a grinder or saw before to extract a fossil from rock, but thought this would be a good opportunity to try and do so. Geared up with my PPE, I used my grinder to put in two relief cuts. Success! The two cuts made it a breeze to knock out with a hammer and chisel. The crinoid is dirty now, but will clean up nicely when I get time to put towards it. I packed up my trophy, and decided to drive out to my campsite for the night. The next morning, I took off to a couple of spots along the Mississippi River. There is a lot of rock along the river and in the area, so research is a must! You could wander around a ton of rock and never find a fossil. I had a secret spot mapped out, and today I was not completely disappointed. I had found the Bainbridge Formation rock I was looking for, though unfortunately there was very little rock exposed. A lot of time was spent carefully scouring the few slabs of exposed stone. Here were a few complete, but weathered Calymene trilobites. Many unsuccessful attempts later, I finally found one I thought that was worth trying to clean up. You can see a small portion of the cephalon exposed. I gathered a few more non photo worthy trilo-bits for my collection, and packed up my finds. I had a long walk back to my car. Once I got back, my curiosity got the best of me so I spent some time picking away at my last exciting find. I carefully exposed it a little bit, but will stop here for now. I am fairly confident it will be a complete Calymene trilobite! A definite happy end to my weekend off work.

probably the only trilobite i will find in Canberra from the silurian
-
First up is a large trilobite pygidium I am not accustom to. Next is what I am guessing is a cornulites. My hunting grounds are devoid of these. Or is it a tentaculites??? There were quite a few of these found as I went through the matrix. Finally a complete mystery to me. Sponge or some kind of echinoderm?????? Only one was found.

Hello all. I have a trilobite pygidium I collected at the end of August, from a site in Lockport, NY. It is Silurian aged Rochester Shale, Lewiston member. I am guessing it is a Dalmanites limulurus, (but I suppose Trimerus dephinocephalus could be a possibility.) Thoughts and opinions welcome. Thanks for having a look.
