I apologize, I am not used to dealing with dolostone of this hardness. The rock of the Niagara Escarpment is serious stuff! What type of equipment besides cold chisels, dental tools and hydrochloric acid should I consider purchasing?

I am wanting to tackle extracting whatever this dark fossil is. But I’ve done very little fossil preparation (other than dissolving stuff with HFl but that’s a story for another day). This is from the Racine Formation from Quarry Park and I picked up a bunch of other pieces to work on for practice. I’m not used to handling dolostone. I grew up with the Mississippian of Indiana, specifically Bloomington-Bedford area. Any suggestions welcome.

Hi, I was recently looking at some small fossils under magnification and think I might have a couple trilobite parts mixed in with a bunch of brachiopods? One fossil appears to be a "cheek" and is about 8mm on it's longest axis, the other appears to be the side of the body and is only about 3mm long. These are from the lower Silurian in Door County, Wisconsin, USA. This area is part of the Niagara Escarpment and trilobite fossils are pretty rare in this area (although I'm sure they were here). I work at a local museum and I'm trying to put together a comprehensive list of confirmed silurian fauna specimens actually found in the county. Thanks in advance for your help! Joe Taylor

Took advantage of the great weather yesterday to drive over to Western Maryland to explore some well-known sites for the first time and had a successful day! Our first stop was at an apparent Late Devonian locality outside of Flintstone where we found nothing except an interesting trackway, which I believe is Pteridichnites biseriatus, made by a brittle star. Otherwise we found absolutely no fossiliferous rock at the site, which is Locality 33 in Fossil Collecting in the Mid-Atlantic States. It's possible the site has been altered/destroyed by roadwork in the ~30 years since the book was written, but if anyone else has given it a try and has had more luck, please let me know! Always possible we were simply in the wrong spot since the directions are bit difficult. Our second stop was a Middle Silurian locality outside of Cumberland, MD where we had vastly more success and that also happens to be about as scenic as roadcuts get with the blooming dogwood trees. We found numerous nautiloid fragments, including one fairly massive one that was also very well preserved and that I managed to get out the rock in good shape (it only broke 4 times!). We also found some lovely brachiopods preserved in a silvery black color and a few large, round corals that are well preserved. We only spent about an hour, but will certainly return.

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.

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?

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.

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.

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.
