Yesterday I was fortunate enough to get back to the Silurian site were I found a complete Dalmanites last month. I met up with @Jeffrey P, @Scylla and his son Grant, as well as their friend Chris who is a member of the New York Paleontological Society. I met up with them around 8:30am. They had gotten there about a half hour or so before me and were already finding things. I spent more time exploring the site then I did the last time as the fossil exposure covers a very large area. I would check out various spots, and it took awhile before I found a good spot to get settled in and do some serious digging. I won't bore you with all the trivial details, but there were plenty of fossils found by all. Brachiopods, bivalves, small horn corals, trilobites, ang even a sponge. I was very surprised by the sponge, which according to Jeff and Gus are rare finds. I actually thought that it was a small concretion and was ready to toss it, but then something caught my eye. There was a small piece broken of the sponge that showed the internal structure. Once I saw that I knew it had to be something and Gus confirmed that it was a sponge. Then a noticed a pattern under the thin film of dirt on the surface. So I was happy. It was only about 36° out but after awhile of digging I ended up removing my jacket as I was getting too warm.( I always dress with many layers in the colder months.) So I set my jacket next to my bucket of tools and moved away a bit. Sometimes later I was talking to Gus when the wind picked up and blew my jacket into the Canal. It was too far out to retrieve it went to the other side. Thank goodness I didn't have anything important in the pockets like my keys or phone. Then a while later Chris had the wind blow his bucket in the water twice. Anyhow, it was really great meeting up with everyone and I had a good time. I will post some pics of my finds and I hope Jeff and Gus will share their finds when they get the time. Sorry not all of the fossils have been cleaned up yet. Pic#1 Sponge 2 Sponge 3 Trimerus pygidium The rest are all Dalmanites partials.

Hello. I was looking at one of my old Waldron Shale hash plates and noticed a round piece seemingly connected to a Bryozoan colony and was wondering if it was the “stem” of the colony, for lack of a better word, or just a coincidentally similar piece on the bottom side of the plate. It also a smaller piece attached to the side that I assume is part of the same column but wanted to ensure it wasn’t an epibiont. Thank you!

I was in Milwaukee for a concert last weekend and I decided that I should revisit the local natural history museum while I was there. The Milwaukee Public Museum was a childhood favorite of mine- it honestly left a stronger impression on me than the Field Museum, and there is one main reason for that: their incredible life-size reconstructions of prehistoric life. So that is where my focus for this report will be. The fossils on display were mostly casts, and nothing stood out to me as particularly notable. Near the entrance, the museum had a diorama showing paleontologists at work, along with some featherless dromaeosaurs. Nearby, though, they had a reconstruction of one with some plumage on: The first ancient ecosystem you encounter when entering the hall of prehistoric life is the Silurian seas that covered the area. This is an incredible display, teeming with trilobites, crinoids, brachiopods and the enormous orthoconic cephalopods. Up next is a small display of tetrapod evolution- this one spans multiple periods, featuring Ichthyostega in the water and Seymouria on the land. Across from this was the Pennsylvanian coal swamp display case. This one unfortunately was very slightly run-down, with some animals from the accompanying identification key missing. But I still greatly appreciate the detail and care that must have gone into creating it. I especially like the attention to detail in the display, and the inclusion of some smaller animals like the coelacanths in the water. I have to pause here, but I will return with my dramatic and enduring core memory of the museum later, the Mesozoic display!

The top picture here is of something I found. It's very small, barely measuring a quarter of an inch wide, and I can't find much on what it could be. I originally thought it may be a graptolite, but I can't find any genera that match its shape. It's similar in shape to a marrellomorph, such as the Furca in the second image, but I haven't found anything conclusive, especially being that Marrellomorph fossils are extremely rare. 2 more things: I found this when I was young so I don't know where it came from, but it most likely ranges from Ordovician to Devonian based on where I've been. Unfortunately I can't get any better pictures as I got this from using a magnifier at the ROM, but as of now I do not have one of my own that I can use to zoom in any closer.

Silicified brachiopod measures 2mm. Racine formation. My wild guess is Isorthis sp. but I really don't know.

Today I enjoyed a wonderful fossilhunt, searching the Silurian age Rochester shale. Our trip was led by an actual Paleontologist who works at a local museum. The main focus of today's hunt were the trilobites Trimerus delphinocephalus,and Dalmanites limulurus. Other known fossils from the site included Leplaena rhomboidalis brachiopods, tiny rugose corals, and rare graptolites. We were informed that while there were plenty of trilo bits and pieces to be found, finding whole ones were a rare occurrence. When we got to the sight some club members started finding things immediately. Cephalons, pygidiums, and thorax segments were abundant. Most of what I found was very small. Until it happened. I split a slab open and found this beautiful Dalmanites!
