    Komp’s Fossil Preps

    Hi all, my good friend @Nautiloidand I have been doing some collecting at a site in the Trenton Group recently and we have been finding what we believe to be Gravicalymene magnotuberculata. The matrix is soft and quite easy to prep, which was a nice surprise. This one was found by my father @Penguin Fiasco Here it was before preparation Bonus headless Triarthrus Beckie appears! All done, now time to clean off the abrasive powder! Here it is after preparation, I am pretty happy with the result. Please excuse the

    Hi all, I found what I presume to be an Isotelus in the Trenton Group of NY yesterday. I posted the trilobite online and someone was saying that it is not an Isotelus based on how the trilobite looks Micropygous, and that they think it is a Proetid (even though the cephalon looks like an Isotelus’?) The trilobite I found looks to be in the Meraspis stage. Can anyone help clarify if this is an Isotelus, or what it could be if it isn’t? Here are some photos of the trilobite… Photo taken with my digital microscope Pygidium

    This is a well-inflated specimen of Isotelus gigas from the Trenton Group of New York. Unfortunately the cephalon is missing, but this is still a pretty rare find. Collected 9/7/2022

  4. Hey there, me again (since my first ever post had great success)! The photos I am about to show you may depict one or two different animals, found in the Neuville Formation of the Trenton Group (Middle Ordovician). The host rock would be micritic limestone and all pictures were taken in Neuville, 30 km west of Quebec City (Québec Province, Canada). Stratas had a subhorizontal dip, slowly sinking into the Saint Lawrence River. Today, I have 6 pictures showing 6 different specimens. The photos might be showing the same animal, but seen from the top AND the bottom (which

  9. Yesterday my dad and I went to a local trout stream for a couple hours just to get out of the house. We did very well with the trout, I got 4 brookies and a brown and he got 7 brookies. On the way back to the car I noticed a small exposure along the side of the creek and took a few minutes to check it out. I immediately saw evidence of trilobites so I dug around some more and I found some nice stuff, including 3 new species for me. The rock is Middle Ordovician Trenton Group and It seems like the Sugar River Limestone. I will be putting photos on here throughout the day

  12. 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 b

    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!
  16. 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

  19. 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 collec
  20. 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 fishin

    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.
  22. 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 w
  23. 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 ma
