    Port Huron, Michigan trip

    I drive 8 hours with a friend to a location he remembers from his childhood as yielding a lot. Oh boy it did. 100% worth the drive. Lake Huron, among the agates, pyrite, yooperlite, has some extraordinary Devonian fossils. All fossils were collected from the beach of his family’s property except for the fenestelid bryozoan, which was found at a gas station on the way there. please enjoy this collection of gastropods, petoskey stones, various tabulate corals, crinoids, stromatoporoids, bivalves, Brachiopods, tenteculites, horn corals, an unidentified agatized fossil in jasper matrix

    Spiked Gastropod from Alpena, Michigan

    Sorry I don’t have clearer photos or anything in here for scale. This is freshly pulled from a ditch in Alpena, Michigan and we’re still out in the field. I had no idea Michigan had spiked gastropods. Any help on an ID would be most appreciated.
  3. A couple weeks ago I took a road trip along the entire border of the lower peninsula of Michigan. One of the days was spent collecting Devonian fossils around Alpena. I visited four sites and had a lot of luck, finding dozens of crinoid calyxes, a couple trilobites, and many other interesting things. It will take me a while to sort through everything, but I did finish cleaning up finds from one of the sites and wanted to share. Nothing groundbreaking, but all good finds for me as I rarely get to collect in the Devonian. The coral Trachypora sp. A partial Dolatocri

    Alpena Michigan fossil finds

    Some finds from our most recent fossil finding expedition to Alpena Michigan. Anyone know species possibly of these two? One with spikes and one without?
  5. This is a small sampling of some of the more interesting things to come out of the Potter Farm Formation in Alpena, Michigan via one bucket of screen washed muck. Crinoid pieces: Cystoid segments: Trilobite fragments: A platyceras: Blastoids: Loads of brachiopods: And tentaculites: Not pictured are the over abundance of bryozoans.
  6. This was acquired in petoskey along the water and I'm still not entirely sure if it's even a fossil at all, it looks like it could be a crinoid stem to me but there are people who know more about crinoid fossils than me
  7. Here’s one (technically three) from the Potter Farm formation (Alpena, MI) that I really have no idea on. Crinoid, maybe? All three pieces are basically the same. I just set them up at different angles so you could see how they looked from different views. Any thoughts?

    Possibly disarticulated cystoid pieces?

    I collected a bucket of muck from my favorite ditch in Alpena (Michigan), and screen washed it. This is the Potter Farm formation. There have been some very interesting things to come out from it. Most of it I can give a basic ID to, but this one has me perplexed. A friend suggested they might be disarticulated pieces of a cystoid. I have never found cystoids before, so this is completely new territory for me. Does anybody have any thoughts? Front: Back: (Sorry about the pen! I misplaced my ruler. Needed something for scale.)
  9. Hello I found this fossil on the beach shore of Lake Huron just north of Port Sanilac, Michigan while visiting. Can someone help identify what it is and maybe how old it is? The fossil image itself is about 3 & 1/2 inches long by 1 & 1/2 inches wide, it appears to have legs on the sides and fins in the back. Thank you!
  10. SilurianSalamander

    What are these Paleozoic fossils?

    All Devonian -ish. First is from port Huron, second is from the Milwaukee formation, third is from the Nike missile site in Waukesha WI

    Devonian worm burrows or organ pipe coral?

    Found two of these fossils now. Both on beaches that are probably Devonian in age. One is from SW Wisconsin on Lake Michigan and the other is in the Lower peninsula of Michigan from the shores of Lake Huron. Organ pipe coral or some sort of burrow trace fossil? Thanks!
  12. SilurianSalamander

    What could this possibly be?!

    Found on a Devonian beach on Lake Huron in port Huron. Thanks!
  13. SilurianSalamander

    Agatized trilobite cephalon?

    Found in Michigan LP. Devonian age probably? Loads of corals and other agatized fossils wash up on that beach. This is the only one I’ve found like this.

    Michigan Blastoids

    Some of the blastoids I picked up while in Michigan awhile back. I'm not sure of their identities, however I imagine it wouldn't be hard with some effort.

    Michigan Fossil?

    Ordovician or Silurian Fossil ID - Help!

    Recently I had found a fossil on a Southern Lake Michigan beach (South Wisconsin / North Illinois) and was extremely confused as to what it could be. Most of the agatized fossils here are of tabular / rugose coral, crinoids, or stromatoporoids. What confuses me is the symmetrical cloud like shape; it does not seem to be a trilobite… Is it some sort of a sponge? or a slug? It is about 3 inches in length. Thanks
  23. Hello! I'm new to the forum- this is my first post. Apologies if I make any mistakes here! My mother has had this dinosaur egg(?) in her possession ever since she was a child- it was gifted to her by her father after he had found it at the side of the road while driving. I'm not sure where specifically it's from or even if it's biological in nature at all. ....Now, I've wanted to finally conclude if this is truly a dinosaur egg (or egg of any other organism) or an interesting geologic formation. Dinosaur or not, it's a beloved object and I'd like to find out it's true identity!

    Interesting rock with protrusion

    Hi, I found a unique sort of rock containing several fossils, some sort of protrusion and it is two toned. A bit of some type of crystal is also present Please see pics. I was hoping someone could tell me a bit about the type of fossils, what the two tone exterior is about and what the protrusion is. Kinda cool. Thanks for your time.
