  1. Hello everyone! So a while ago I collected a couple of rocks while fishing up near Plattsburgh, NY. These rocks were from the Ordovician Trenton Group and contained a variety of organisms including inarticulate brachiopods and corals. More importantly though, were the variety of trilobites. In one of the rocks I found pieces of Isotelus, Cryptolithus, and Ceraurus. I was looking at a small piece of that rock yesterday when I noticed a strange little fossil. It was a tiny, spiny free cheek of a trilobite! It looks very similar to Meadowtownella trentonensis although it could be a different species. I do apologize if the pics aren’t great but the fossil is so small that I had to use my microscope to see any detail lol. Also, how do I get my images to be not turned sideways? Thanks for looking! Owen

  5. Mystery hypostome in need of ID

    Hello everyone! So I was cleaning off a rock today and on it I found this tiny hypostome. I was wondering if anybody has an idea of what species this may have come from. This rock came from a site in North-Central NY that exposes the Ordovician Trenton Group. Thanks for looking!
  6. Greetings everybody! While I was on my fishing trip last weekend I took some time to look for fossils. I collected at a couple of creeks exposing the Middle Ordovician Trenton Group in North-Central NY. I found lots of trilo-bits and other goodies! Enjoy

  9. It was an all day outing on a perfect spring day in Central Upstate New York. Al Tahan and I visited a small private quarry where the Middle Devonian Oatkacreek Formation Mottville Member, part of the Marcellus Shale and the lower Hamilton Group is exposed. It's been about a year since I visited the site which I've been coming to for the past five years and it was Al's first visit. Erosion had broken down almost all of the pieces of shale which covered much of the site on previous visits. However a lot of fossils here, preserved in calcite are weathered free from the matrix and surface collecting can be very productive. This is by far the best site I've been to for the gastropod, Bembexia sulcomarginata. There were dozens strewn about the site. I couldn't resist picking up a few adding to my already extensive Bembexia collection. Brachiopods were also plentiful, especially the large spiriferid, Spinocyrtia granulosa (upper right). I couldn't help adding this inflated example to my large collection. Upper left is Mucrospirifer murcronatus, certainly one of the most abundant and distinctive Middle Devonian brachiopods in New York. Lower left is Protoleptostrophia perplana, a Strophomenid.
  10. Hey everyone, Haven’t posted much about my recent activities so this is a summary of a few things I’ve been up to the past month or so. I had a lot of goals in 2020 with regards to exploring more of the Ordovician rocks in New York. I am very interested in the Ordovician due to the formations and groups represented. The Trenton group, Lorraine group (has whetstone gulf fm and Pulaski fm) have been of great interest to me because I live in Central New York and these rocks are actually very close to me. Last year I did some exploring and it worked out pretty well. I found a great fishing stream with the Pulaski and whetstone exposed. I also found some exposures of Utica shale that I know are promising. I was also able to get permission from a land owner In November to visit a location with the Trenton exposed but I wasn’t able to actually go there till this year. I am going to share my experience with 2 different rock groups I visited recently on several different field days in April and May. The Trenton group and the Lorraine group. Lorraine group, Whetstone gulf exposures northwestern New York Beechers beds. Lorraine group, Frankfort shale Trenton group exposure. Recent permission. The Whetstone gulf formation is probably familiar to many people who are obsessed with New York trilobites, especially the pyritized trilobites. Other than pyritized Triarthrus some may not know about the other fauna found in the Whetstone. Also...nobody is really looking either. Reasons being difficulties getting to the exposures, proximity to state parks and state forests, nobody lives near there so travel is required, private property issues, and LOTS of walking is required. North of Rome, New York around the northern and eastern edges of the tug hill plateau are several enormous gorges with breathtaking exposures. Depending on how ambitious you want to be there seems to be plenty of exposure to see. The whetstone has been regarded as an impossibility complex system with 100s, even 1000s of faunal zones (perhaps a hyperbole or the musings of a frustrated paleontologist!). The fossils that have been found in the whetstone aren’t Fully documented and more work is needed. There are Eurypterids (parts only, super rare) and rare trilobites that have been recorded to be found that are not easy to find information about today. It’s like chasing a ghost trying to even find photos of these fossils. Rudolf Ruedemann wrote a magnificent publication on the Utica and Lorraine formations of New York (1925). Since then his work remains, to me, the best source regarding these formations. Here is a few plates from that. Interesting stuff. Some of the names have changed... Last year I found a calymenid pygidium in some Pulaski formation “drift”. I didn’t hike far enough to reach the whetstone that day so “seeing” the whetstone and exploring is a 2020 goal. Some of the possibilities.....I didn’t find these. These are just examples of a few nice arthropods from the Whetstone. A complete Homotelus stegops from the Whetstone gulf formation. I guess these are very rare A legitimate specimen of some Eurypterid body segments. Whetstone material. Exceedingly rare. Continued.....
  11. Unknown critter from Ellisburg, NY

    I found this while fossil hunting in a creek near Lake Ontario in NY. It is Ordovician in age and I believe it is from the Trenton group.
  12. Hello fossil folks Just another one of those “Rediscovering New York” posts. This Edition will include my efforts looking for the Trenton group and exploring the Pulaski formation. More Ordovician exploration in the central New York area. This past Saturday me and my good friend Matt did some trout fishing in the Rome area and another town north of Rome. I had scouted these spots for 2 reasons.....trout and trilobites! One location seemed to have Trenton group exposures and another I had already confirmed as the Pulaski formation but wanted to explore it more. Both were located on stretches of the Mohawk River and anyone can go fish/hike these waters. I learned of another Trenton group exposure with trilobites but it’s posted trespassing. Eventually Ill get the courage to do some door knocking in the area to try and find the owners. I guess I don’t know what I would say lol. I wasn’t really in the mood for that so I went to legal stretches of the Mohawk River for this adventure. The goal: 1. Find Trenton group exposures 2. Confirm trilobites from the Pulaski formation 3. Catch trout!!! More to follow....
  13. The weekend of June 24th and 25th I participated in an outing with the New York Paleontological Society led by my friend, Ray McKinney to Brechin, Ontario. TFF Member Malcolm led our group into the James Dick quarry where both Bobycaygeon and Verulam Formations are exposed. These are Middle Ordovician from the Trenton Group and contain a wide variety of invertebrate fossil fauna. Also met other TFF members Kevin (Northern Sharks) and Joe (crinus). Most of the quarry is the Bobycaygeon and the very top is the Verulam- only accessible near the entrance, but I got some excellent well preserved matrix plates from there. I spent the second day combing the spoil piles. This first picture is Lake Simco by Beaverton where we stayed. Malcolm in the middle, explaining the quarry geology to NY Paleontological Society members.
