  1. During the Christmas holidays, i had the opportunity to go out again for a trilobites hunt. Could spend 2 days there splitting shale. The site is Ordovician. The plan is to split good looking shale blocks, the bigger the better. For site pictures, you can go check on my previous report here I manage to find nearly complete or nearly complete bugs. The first morning, complete ones took their time to show up. The first one was this one : Neseuretus tristani, the most common on the site, but still a cool piece. On it's own it would have make my day. I will post more in a few days

  15. Last week, after checking the weather wunderground numerous times, I decided to drive 3.5 hours from Chicago to St. Paul Stone Quarry. It was the last "open house" day according to the ESCONI website. I arrived at 7:45, the first and only person there. Shortly thereafter, after a brief safety instruction, I followed the manager to the collecting site, heaps and heaps of Waldron shale. Even though I dressed in layers, I still had to take breaks and warm up in the car for a few minutes, but I much rather prefer collecting in cold weather as opposed to hot summer sun with mosquitoes, any day. It didn't take too long to start finding fossils. Here are just a few of my finds: Eospirifer Platystrophia brachiopods with pyrite Platyceras niagarense encrusted with strophomenid, bryozoa and pyrite. front: back: Partial Dalmanitid Trilobite in matrix When prepping, it's really wonderful how the waldron "butter" shale just crumbles apart around the predictable morphology of an enrolled trilobite. The trip just wouldn't seem complete without a short drive east to the Cincinnati Arch roadcuts. I first went to South Gate and found a flexicalymene eroding right out of the cut. It is interesting to see the comparisons here. The trilobite on the left is from St Paul (Silurian) and has beautiful pyritized eyes. The one on the right is from South Gate (Ordovician). Both trilobites have 21 articulated segments; does this make them both the same age as "adults"? Interesting to note the difference in size, being 40 million years apart, same species.. Thanks for looking!
  16. Is it possible to narrow down the location for these Sphenothallus sp. from the Whetstone Gulf Formation of New York from just "Lewis Co, NY"? Maybe more about the stratigraphy too (ie. what North American stage of the Ordovician?) I suppose I could ask the seller but I'm going to assume the info they gave was all they had or were willing to divulge, and I know TFF has a good knowledge base, so... The info I got was: Sphenothallus sp. Upper Ordo (Sandbian), Whetstone Gulf Fm, Lewis County, NY. Also stated this unit is where the pyritized trilos with soft parts preserved come from (not the exact site I guess).
  17. This weekend, travelled up north to Plattsburg to visit my friend Ray I know from the New York Paleontological Society. The next day took the ferry across Lake Champlain to Grand isle, Vermont and met Andy (Cluros) and his father. Here are some pics of the ferry ride over:
  18. Ectenaspis Sp.

    From the album Fayette County Iowa

    This is a find from earlier this summer that I just got out tonight to start work on. I assumed when I collected it that it was an Isotelus Gigas and didn't give it much of an inspection. I did tonight though. Appears to actually be an Ectenaspis Sp. A Good surprise.
  19. Each summer I collect near Newberry in the U.P. of michigan from a degrading hillside. I usually find nodules containing graptolites, various "shell" type impressions from brachipods, and trilobite impressions. Generally the nodules I crack open are not more than 3 " . This summer, a large piece of shale was sticking out of the bank, so I dug it out and split it. It had several orthocone fossils and impressions, ( though I don't know what kind) and was filled with impressions of little cone like images. That is a dime for reference, and you should be able to clearly see the cone impressions, are these baby orthocones, a small species or belamites of some kind. As always, thanks for the help. According to the director of the museum in Quebec, the area is ordovician, but some suggest it is silurian.
  20. This is my first trip report on the forum, an attempt to organize my finds and hopefully get some help with identification. The quarry was located near Rockford, Illinois, Ordovician period. Recepticulites, in the field. Not sure what this impression is. Any ideas? An assortment of brachiopods and gastropods in beautiful bone-white chert. Not sure what this is...sorry for the blurriness, my phone doesn't have the best camera. Gastropod and recepticulites chunk Top and bottom halves of recepticulites. Not sure what these tentacles are... Bryozoans perhaps? Here they are under the microscope. They appear golden only because I naively used a brass brush to clean them (oops!)... a nice effect nonetheless.. Thanks for looking!
  21. Im going to start putting all my trips under 1 topic (easier to find that way.) Ive been collecting three to four times since my last trip report. This included a trip west to the Ordovician (to scout for new roadcuts) a trip east to look for the Nolichucky Shale (Cambrian) and a recent trip to the abandoned quarry I used to frequent (Mississippian, Bangor Limestone.) the Ordovician trips went well, and I managed to collect a wide variety of fossils. I collected from two formations, both of which I had collected from before, but at different locations. The Leiper's (which I cant seem to escape from ) and the Hermitage; of which I was pleased to find another exposure of. First was a whole bunch of brachiopods (of which this is a small sample.) a.) Hebertella occidentalis b.) Platystrophia sp. c.) Rhynchotrema increbescens d.) Onniella sp. e.) Dinorthis pectinella Rhynchotrema seems to occur in the billions in the Hermitage. next up is the bivalves, which are fairly abundant in the Leipers, these mostly consist of internal molds. a and d.) Modiolopsis modiolaris b.) Caritodens sp. (a rare internal mold around here) c.) Ctenodonta pectunculoides (side view, beak is to the right) and a nice mass mortality plate of (mostly) bivalves I picked up at a road-cut on my way home from the last trip west. Its upper Ordovician. the most common ones (labeled a.) Modiolopsis b.) a razor clam, most likely Orthodesma sp. c.)a strophomenid brachiopod d.) an orthid brachiopod, probably Hesperorthis sp. Bryozoans were everywhere but I only picked up a few; I did very well on sponges however a.) a semi-smooshed sponge Hindia sphaeroidalis (with matrix still attached) b.) two nice bryozoans that I haven't ID'ed yet cont. next reply....
  22. Conularia formosa

    From the album Urban Fossils of Toronto

    Found at Mimico Creek, Toronto, Ontario. Late Ordovician period. This specimen is a positive with a negative counterpart on limestone. This was also found along with a bunch of other Conularia specimens back in the end of Summer at 2015.
  23. Hello everybody. I would very much appreciate your opinion on a fossil you can see on the picture. It's from Tennessee - Ordovician - Chickamauga group. Thanks.
