  1. Fossildude19

    Juvenile Isotoleus

    From the album: Fossildude's Ordovician Finds

    Found in West Canada Creek at the KOA campground in Herkimer, NY. Ordovician. Juvenile Isotoleus sp. Note the Hypostome visible in the center where the top of the cephalon came away.

    Beecher's Trilobite Bed Triarthrus

    From the album: Fossildude's Ordovician Finds

    Triarthrus eatoni, from the Martin Quarry - Beecher Trilobite beds. 1 cm in length. Late Ordovician (Caradoc) age, Frankfort Shale, Oneida County, New York, USA.

  3. Tales From the Shale

    Wisconsin Ordovician 09/27/22

    Years of searching Wisconsin's various websites and old Geo surveys have always yielded varying levels of success ranging from mediocre, to misses entirely. Not this time, this is effectively the best hunting I've ever had in my home state. Period: Ordovician Formation: Platteville Location: SW Wisconsin Endoceras? I say that primarily based on size. Goniaceras, the flattened curved shape seems to support that? Gabriceraurus mifflinensis? It is a fragmentary cephalon, but that species is more common than other Ceraurids that I've read about
  4. Nautiloid

    Small colony of Diagoniella

    From the album: Ordovician non-trilobite fossils

    This colony of Diagoniella sp. includes a few small specimens and one large specimen. Part of a huge colony that was collected from the Beecher’s Beds (Upper Ordovician, Frankfort Shale) in the fall of 2021.

  5. Nautiloid

    Two Utica Shale sponges

    From the album: Ordovician non-trilobite fossils

    These are pretty nice pyritized specimens, despite a lack of spicule preservation. They remind me a little bit of the Diagoniella from the Beechers Beds.

  6. Nautiloid

    Utica Shale sponge

    From the album: Ordovician non-trilobite fossils

    This is probably one of my favorite sponges from the Utica shale. It has awesome spicule preservation, is almost 2 inches wide, and stands out from the rock much better than most of my other non-pyritized sponges do. Someone once told me this was a rare Utica Shale phyllocarid, but phyllocarids don’t have spicules lol.

  7. Nautiloid

    Oddly shaped Utica Shale sponge

    From the album: Ordovician non-trilobite fossils

    At first glance, this specimen does not look at all like a sponge, but the wonderful spicule preservation would say otherwise. Not sure why this one is shaped so strangely.

    © Owen Yonkin 2022

  8. Nautiloid

    Utica Shale sponge

    From the album: Ordovician non-trilobite fossils

    This specimen is not all that visually appealing, but it does have great spicule preservation. The non-pyritized ones tend to be larger and have better spicule preservation.

    © Owen Yonkin 2022

  9. Nautiloid

    Colony of Utica Shale sponges

    From the album: Ordovician non-trilobite fossils

    These aren’t the best preserved sponges I have from the Utica Shale, nor the largest, but it is the one of the largest colonies I’ve found. There are 8 specimens on one side and 4 on the back.

    © Owen Yonkin 2022

  10. Nautiloid

    Pyritized Utica Shale sponge

    From the album: Ordovician non-trilobite fossils

    This is one of my best preserved sponges from the Utica Shale. It has much nicer spicule preservation than any of my other pyritized specimens.

    © Owen Yonkin 2022

  11. Nautiloid

    Utica Shale conulariid

    From the album: Ordovician non-trilobite fossils

    This is a relatively small (~1 cm) conulariid from the Upper Ordovician Utica Shale of New York. It’s sorta weathered, but you can still make out some of the structure, especially under a more powerful lens.

    © Owen Yonkin 2022

  12. Nautiloid

    Cryptolithus bellulus

    From the album: Nautiloid’s Trilobite Collection

    This is a nice specimen of C. bellulus from the Upper Ordovician Reedsville Fm. of Pennsylvania. Acquired from an old collection.

    © Owen Yonkin 2022

  13. Nautiloid

    Lemureops kilbeyi

    From the album: Nautiloid’s Trilobite Collection

    This is another specimen of one of my favorite trilobites. This little guy comes from the Lower Ordovician Fillmore Formation of Utah. Acquired from an old collection.

  14. Nautiloid

    New York Isotelus gigas

    From the album: Nautiloid’s Trilobite Collection

    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

  15. I had brought home a piece of Galena/ Ordovician matrix that had some unidentifiable critters hidden in the rock. Time was taken to extract what I am sure is a cephalopod from the matrix. Haven hunted this formation for years, I can honestly say this is the first cephalopod found exhibiting its curved features discovered by me. Attempts to ID the fossil have been fruitless, so I am asking for help! The fossil fractured during its prep revealing what I see as a siphuncle. Here is the repaired specimen:

    identification please

    Good evening to everyone who comes to see my post, I thank you in advance for the time you take to read the question you presented, which would be the first of several specimens that I have not been able to identify. About two years ago I started hunting for fossils almost by luck as I was looking for minerals until I found the first turritellas, on one of these trips I find a rock of considerable size and weight with a curved linear pattern similar to "worms" although I honestly don't really know what it is, I have found trace fossils but never horizontal, and less than that thick, I ha
  17. Tidgy's Dad

    Adam's Ordovician.

    A nice Dictyonema flabelliforme dendroid graptolite from Oslo Fields in Norway. It's Tremadoc, Lower Ordovician in age and is thus maybe around 480 mya. Another angle :
  18. Hello, This is my first post. I recently purchased this item being sold as an authentic trilobite. It was in a box of about 12 and I purchased it cheap. If it's real, fantastic. If not, it's a minor loss. It is 3.75 inches/9.525 cm long. Please see the attached photos Thank you for all your help! Dave
  19. Tales From the Shale

    Iowa Trip 09/03/2022

    Traveled to Iowa for a second time this weekend. My goal was the various molt beds of Isotelus in Fayette county. Here are most of the finds. While there I stumbled upon a local hunter who was nice enough to give me all of his hunting spots. He seemed to be as surprised as I was to find someone else in the field. A few isolated hypostomes here, and some others in various hashplates. Mixtures of pygidiums and cephalon structures. I think an eye can be seen in each of these images. Some decent sized pygidiums. They were the most common part of the

    What is this 3d puzzle ?

    I found this yesterday, it was very fragile and broken in many pieces when I handled it.
  21. aek

    Seems fishy

    Any idea what this tiny fragment could be? Found in a sample containing conodonts and other microfossils.

    I came across this unusual scolecodont and can't identify it. Late Ordovician Drakes formation. Any help appreciated.
  23. From the album: Fossil Art

    Ordovician, Nicolet River Formation, Sowerbyella & Crinoid sterms
  24. Denis Arcand

    I think it's a bivalve, but which one?

    I know there aren't many details for a formal identification, but even a guess would be fine I found it in the Nicolet River formation (Late Ordovician)
  25. I was busting up a few rocks from the Ordovician/ Galena of SE Minnesota when I noticed this unknown peeking out at me. It would be nice to understand what it is so a decision as to whether to expose more of it can be made. Thanks! By the way, it is 6 mm in length. Mike
