  1. Hello, im new in fossiles collecting, absolute new beginner. I wonder if my fossiles are genuine or fake, i was so proud of my collection but after i learned that there are many fake Moroccan trilobites on sale, i had suspicions. There are some holes in trilobite and some stuff on it, could be glued which is fine because its age matters to me most, it could be glued no problem. I put them under a plastic sheet but if you wish i can take them out to take better pictures.

    Reliable sources for Fossil ID

    Hey everyone, More experienced hunters than me, what sources do you use for general knowledge and IDing your finds? I have a brachiopod from the order Spiriferida but I can't find anything online to go any more in depth than that. Is there a specific book or website that I should check out?

    Trilobite Mortality Plate ID

    Hi everyone! I purchased this trilobite mortality plate a few months ago, but I haven't gotten the chance to get an ID yet. All the info I have on it is that it was collected near Tafraoute, Morocco and is from an Ordovician formation. (not sure which one) They are all about an inch and unfortunately most of the heads are not preserved great. I can provide bette r pictures if needed. Thanks!

    Collection of trilobites I've found

    Here are some of the most intact trilobite fragments I've collected from breaking apart shale. Pic 1 is very well preserved though I do wish there could have been more of it. Pic 2 may have some of the best 3-D nature to it, especially where you can see both sides. Pic 3 looks really awesome in my opinion, but what really sells this one for me is what I suspect to be a horseshoe crab in the bottom middle, though additional input is much appreciated. Pic 4 is the first one I found from shale. Pic 5 is the first trilobite I ever found on my first fo

    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 :

    Odd shapes in shale

    Few weeks ago started breaking open some pieces of shale. I've found lots of trilobite fragments that I'll post later, but what's intriguing me is these small bits of things that I find quite a lot. I can't find anything on what they might be and my closest guess is perhaps some bits of crinoids? Does anyone have more experience than me with such things?
  7. Unfortunatly this is is a piece found at the outcrop bottom, no opposite mould available. Important: this is a DECALCIFIED specimen, so you see the calcified part negative. Ordovician, scale bar 5mm. 2 pics of the same specimen. Any ideas? Echinoderm? Porifera? Bryozoan?...

    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)
  10. Hi Everyone, Last month I took a trip from New York to Elizabethtown, Kentucky to attend my parents' 70th anniversary. My sister and her husband, two of her adult children, and my parents, both in their 90s have all resettled there. I try to visit them at least once per year, but my parents' 70th wedding anniversary could not be missed. It is a very long trip from the suburbs of New York City to E-Town and a stop along the way was the sensible thing to do, so I spent the night in Harrison, Ohio near the border with Indiana and only 15 minutes from St. Leon, the well known Ordovician roadc
  11. Earlier this month I spent a day collecting in the Kope Formation (Upper Ordovician) of northern Kentucky. It is one of my favorite formations to hunt, and I always walk away with some nice stuff. Here are some of my better finds. A decent Ectenocrinus. It is crushed but should turn out nicely after prep. A much smaller Ectenocrinus hiding in a hash plate A pretty classic Kope hash plate. There's a cluster of crinoid arms to the left of center - I doubt there is a calyx but we'll see. A very nice Cyclonema

    Stem shaped object

    Found this object on a piece of shale. I suspect it might be a crinoid stem but it's really hard to see very much detail as it's so small. There is a trilobite when I split the piece in half in case that helps, though I'm looking for some more experienced eyes to help me out with id, thanks!
  13. Nautiloid

    Good sized Gravicalymene

    From the album: Nautiloid’s Trilobite Collection

    This is the largest Gravicalymene I’ve collected so far at over 1.25” wide. It required quite a lot of gluing but it should turn out pretty nice when all is said and done! Collected 11/04/2022

    Possible brachiopod or something else?

    Hey everyone, As you can see here I have a piece of shale I broke in half, which revealed this brachiopod like shape. At first I thought it was dust but what's left here can't be brushed away any more. Looks to me like it's too symmetrical to be a natural formation, but I could use some input at to whether it's a fossil or not, thanks!
  15. Bringing Fossils to Life

    Unknown fossils from the Coburn Formation

    Recently I went fossil hunting along a road cut revealing some of the Coburn Formation, latest Ordovician. I was stunned to find that so much of the ecosystem was made up of only Trilobites and Cephalopods. I found trilobites such as Isotelus and Cryptolithus (First picture). My find of the day was a large, very heavy plate of rock that preserves different parts of large Isotelus gigas from multiple individuals, and the circular cross-section of a small cephalopod (Second picture). However, I'm having trouble identifying these cephalopods. In the very few that preserve the outer sell, faint s

    Maybe fish?

    I found this rock with this odd shapes in them. They all mostly seem to have similar shaping and I suspect they may be early Ordovician fish. Any thoughts?
  17. Nautiloid

    Huge Isotelus gigas

    From the album: Nautiloid’s Trilobite Collection

    This bug is in rough shape but I still kept it due to its massive size. It would’ve been 10.5-11.5 inches long if the bottom half of the pygidium wasn’t MIA. As you can see, the left half was exposed to the elements and is heavily weathered, but the right half is still relatively salvageable. This is by far the largest trilobite I’ve ever collected! Collected 11/04/2022

    Super nice Isotelus gigas

    From the album: Nautiloid’s Trilobite Collection

    This bug is exactly 6 inches long. It’s not super inflated, and a small piece of the pygidium is missing. Other than that it’s pretty much perfect! From the Trenton Group of New York. Collected 11/04/2022

  19. Hello, this slab is from the Kope Formation, particularly Upper Alexandria sub-member within Delhi Township, Ohio. I am unsure if these rounded "structures" are bryozoans, echinoderms, or brachiopods, but i'm leaning more toward bryozoans. Fauna on the slab include: -Cincinnaticrinus, Ectenocrinus -Retrosirostra OR Dalmanella (hard to distinguish) -Bythopora -Isotelus, Flexicalymene -Ambonychia If anyone has an idea as to what the round objects are, please comment! Thank you! EDIT: I now believe these are individual ceph

  21. Over the last month or so, I've managed to get out to a few places. Although I can't say I've made stellar finds, I made out okay. In order of geologic sequence, I'll start off with the Ordovician. I have a spot in the Cobourg/Lindsay Fm that is typically very high energy, and so complete trilobite specimens are scarce. A few Isotelus parts, a Pseudogygites latimarginatus pygidium, a Ceraurinus marginatus glabella, and what may turn out to be a complete Flexicalymene senaria prone (to be determined after prep).
  22. Fall promises to be spectacular in many ways. If you dream of colors, you will like the following. I like fossil hunting in the fall, although it's not really hunting, the fossils are underwater so it's more like fishing. Anyway, this is one of my many trips to this place, it's not very far and it allows me to go for a weekend nature walk. This is Ordovician, the site is not as beautiful or rich in fossils as the other sites we see in this forum, but it is rich in brachiopods, crinoids, bryozoans and gastropods. This time, I chose a theme to showcase my special finds of the day.

    Ordovician decalcified specimen, the two moulds Scale bar: 5mm I would guess Fenestrida bryozoan, but might it be some sort of echinoderm "thing"?
  24. Jan Lester

    What are these?

    My husband and I went hiking today, and I started looking at rocks, and I think every single one had fossils in it! Many of them had a similar shape, which I see quite a bit around here. I have no idea what it is, though, maybe the inside of a brachiopod? Maybe a cross-section of coral? Thanks for any answers.
