  1. On our trip out to some Rocky Mountain states this past summer, we found red agatized horn coral in the Uinta-Cache National Forest. Back home, we polished the agate, which is jewelry-grade material and transparent--so real agate, not jasper. Here's the video we created about our trip. Lloyd
  2. I've been working on a Petoskey Stone presentation for my rock and mineral club and have been collecting various colonial rugose corals that have been on sale on online and Etsy. I've been doing this because "Petoskey Stone" has become a popular name to use to sell fossilized coral and I want to be able to show our club how to differentiate Hexagonaria from other types of coral. I've gone through this forum and gleaned some data from @TqB and @FossilDAWG while they were helping out on IDs and was wondering if anyone could help me fill out this cheat sheet with more information (and correc

    Help ID this????

    Hello, I was gifted this fossil. All I know is that it was found in Tennessee. I believe it is a coral fossil but because of the 'stems' I can't find anything that matches it online. I know fossils cant be valued for price on here but if this is rare and I should contact someone about having it I would like to know. It is in limestone with quartz sparkles in the 'coral' pieces. Thanks so much!
  4. Visiting family in Kentucky and went to the Maysville Cut for 2 hours yesterday. Found some neat things. I wanted to find a trilobite, but no real luck. I think I may have found a piece of one.

    Can anyone ID this?

    My 13 year old son found this at the beach in Destin, FL. It reminds me of a tooth, but it's not pointed. Any ideas of what this is?

    Northern MI Coral Fossil

    I found this in with a bunch of Petoskey Stones from the Alpena area, but I'm not quite sure it is one too. It seems like the calyxes are further apart than they are in Hexagonaria. Does anyone have an idea what this is? I'll go ahead and tag @TqB myself. Thank you for the help.

    Tampa Bay Fossilized Coral Branch?

    Hi Fossil Hunters, I found this unusual piece on Honeymoon Beach, Florida. It's not the typical shaped coral I find and has corallites on the base. I wanted to know what kind of coral and if it's fossilized or just a limestone cast (Steinkern)? Florida Guys I could use your help. @Harry Pristis @Plantguy @Shellseeker Thanks! Lynn
  8. Hey! I'm a bit new to this, so please forgive me A friend recently gave me a bunch of fossils she bought a while ago. I've been trying to identify them - most of them are relatively straightforward, but I'm not sure whether this fossil is a piece of coral or a byrozoan (fossil length 4cm). Any help would be much appreciated.

    Pyritized Hexagonaria Coral

    I purchased this from someone who said it was a Hexagonaria coral found at the Rensselaer Quarry in Indiana and it is covered with a coating of calcite and pyrite crystals. Can anyone verify that this seems to be a correct identification?

    Ontario Coral Fossil

    I purchased this from a woman in Ontario, Canada with no other information as to what it may be. Does anyone have any ideas?
  11. I purchased this from someone in India who claims it is a Hexagonaria from the US. I have severe doubts that this is true. It looks like Moroccan coral to me. I base this on Petoskey Stones are rarely agatized, the corallites seem to be larger and not as hexagonal as they should be for Hexagonaria, and Moroccan coral seems to be yellow quite often, while I have only seen a couple yellow Petoskey Stones and they both have a lot of inclusions. Does anyone have any idea whether this is Hexagonaria or not?
  12. I purchased this from someone in the UK who said it was Hexagonaria from Alnif, Morocco. Does anyone have any idea if this is correct?

    Moroccan Cabochon Agatized Coral

    I purchased this from a shop in India that claimed it was a Petoskey Stone from Morocco. Obviously, this isn't true and I feel like it is probably not a Hexagonaria. Does anyone have any idea what it is? (Sorry about my phone leaving shadows and the images up.)

    Coral Fossil Pair ID

    I am brand new to the site, though I've been using information from it for awhile to help me prepare a Petoskey Stone presentation for my rock and mineral club. I am a novice and have just joined and started collecting. I graduated high school from Petoskey, so I thought I would start with Petoskey Stones. I no longer live in Michigan, so have been collecting specimens online for my presentation. I have a ton of Petoskey Stones. I am now collecting Hexagonaria from other locations and other corals, especially Rugose corals, that may be confused (either intentionally or not) with Petoskey
  15. I purchased this from someone in the UK that said it was Hexagonaria from Ireland. Does anyone have any idea if this is true?

    Coral from Alaska

    I purchased this from a store in Alaska. I have no information about it at all. It looks similar to what I'm seeing online about Stingray Coral, but I can't find out anything about what that actually is. Does anyone have any idea what this might be?

    Hexagonaria quadrigemina?

    I just posted on two other corals. I have several that I need help with identifying. Please forgive me for the spam. I thought it would be easier to post one or two rocks per topic rather than put them all together. I purchased this one from online from a pawn shop in Florida. They claimed it was a Hexagonaria quadrigemina. Does anyone have any idea whether this is true?

    Purple Petoskey Stone

    I purchased this from someone in a Detroit suburb who said she collected this herself (no further information on location). It is a mess and I cannot tell if it is truly a Hexagonaria or not. I've had several collectors from Michigan take a look at photos and we cannot come to a consensus. Does anyone have an idea on what this might be? (Sorry for no cm ruler. I've misplaced the rock somewhere.)
  19. I purchased this from a shop in Iowa that said it was a glacial erratic. Does anyone have any idea on what type of coral it is?
  20. I purchased this from a man who said it was found on a mountaintop in Tennessee. I have no other information about it at all. Does anyone have any idea what it might be?

    Rugose Coral from Kentucky

    I purchased this from someone in Kentucky. It was labeled Rugose Coral fossil with no other information. Does anyone know what type of Rugose it is?

    Strange structure

    I don't even know which direction to go, geological or biological, and given the weird concretions and burrows in Eagle Ford don't know where this fits in so looking forward to answer

    Mudlarking the Meramec River in Missouri!

    Hi everybody, I'm a neophyte to the geological realm (especially regarding paleontology), but I thought I'd share some finds on the forum. In Layman's terms, I found some clams, possibly some coral, and (...wait I know this one) Crinoids! Any possible fossil ID would be great, happy to be here, and glad to join a community with similar interests! All items below were found within 100-200 yards of each-other on the Meramec river just outside of St. Louis, Missouri. 1) 2) 3) 4)
