    Going through a family member's old stuff and found this along with a few other dinosaur bones. They grew up in San Juan county Utah, so this was likely uncovered from that region, but I can't say with absolute certainty. I don't know if this is a fossil or just a geode. I myself have almost no experience in this area. Any help appreciated. Thank you!

    Graf Iowa Geode

    A sizeable mineral coming from the ever famous Graf roadcut that exposes the Elgin of the Maquoketa. Im thinking calcite, but im gonna be honest I haven't a clue.
  3. My brother found this while hiking I believe around Mammoth Lakes, California. Its almost perfectly round and feels somewhat light so it may be hollow. Google says its a concretion. My mom thinks its a Geode. What do you think?

    Unfortunately I don’t have any provenance for this rock. I bought it years ago screwed to a piece of driftwood for my fish tank. When the driftwood had withered away to a twig, I was throwing it away, but noticed the fossil traces on the rock and kept it. Came across it a few weeks ago, and started messing with it. The fish store was local, and I would assume that this was created by a somewhat local person (in east TN), but I don’t know. The top of the “calyx” is translucent from the underside. Not the softest limestone I’ve found…I can see signs of bryozoans and brachiopods, but it’s hard t

    Type of geodized fossil?

    This was found on one of my recent hikes in a creek bed in south-central Indiana (Monroe County). Geodes are very common finds as well as crinoid columnals and horn coral but this is the first find of this type. So I would think it is some type of geodized fossil but would like the experts' opinions. The first 3 photos (taken in natural sunlight) are "side" views and the 4th shows the "bottom". What do you guys think? Thanks in advance for your feedback.

    Little something...unsure?

    Hi all, I have this little object. Just wondering if it stands out to anyone. Thanks all.

    Help identify this fossil

    Please help me to identify this fossil. I am new to this and came across this unique find. I gave Google lenses it and came up empty. Any help to this will be greatly appreciated. Thank you.
  9. Hi guys not been on much due to limited internet sorry however I had ordered a 'geode' from a seller in China cheapish it is around 1.9kg in weight and it arrived. It looked like something I had seen before and sure enough I found similar listed as a dinosaur egg on the famous auction site, just wondered everyone's thoughts on what it actually is lol? couple of pics attached, im sure it is neither an egg or a geode personally

    Geodized fossils?

    I'm a newbie to The Fossil Forum. I hike in the hilly areas of south-central Indiana (mainly Morgan, Monroe & Brown counties) whenever I get a chance and many times I end up walking the rocky creek beds looking for fossils & unusual rocks. These creeks are rich in geodes and there is a lot of shale & limestone. I believe that some of the unusual finds are geodized fossils. I have several that I'd like to share with the forum to get opinions from the experts. Attaching multiple photos (15 total: 3 groups of 5) of 4 different specimens with the first five photos showing a pair w

    Sylvania brachs

    I was in Sylvania OH this weekend and among many other pieces, I found these. I finished prepping them as soon as I could. The first is a pyrite paraspirifer bownockeri.....it is perfect, not a blemish or chip. This one is a paraspirifer (I think) but different. About 2 inches across. Has a few flaws. Then there is another pyrite bownockeri, same size as the first one, nearly perfect but for a chipped "wing" and a hole. But the hole exposes that it is also a geode....containing calcite I believe. I've never seen or heard of a geodized pyri

    A Very Tiny Mystery

    Hello wonderful fossil-people! If you and you're gang enjoy solving a groovy mystery, I have a post for you! This rock was found in an area of Northern Arizona that is very well know for producing lots and lots of bryozoan, brachiopod, and crinoid fossils, as well as crystals and geodes. The bit of rock in question was found in the side of what appears to be a broken geode. There is a triangular fragment of stone that does not match the material surrounding it. There is also a white discoloration encompassing the triangle that I've highlighted in green on one of the photos below. The colo
  13. Hey all! So I found what appeared to be a large geode, but upon further investigation turned out to have 5 or 6 fossils imprints! They seem to be seashells, scallop-like so possibly bivalves or brachiopods. I'll attach the pre-cleaning pictures below, then some more later after I rinse it and dry it off. My big question is: since this thing definitely has fossils (I can see at least two are half buried in the stone matrix) and is very likely a geode (it's heavy, has dimples, and I can see shiny facets in a few of the dimples), what should be next step be? I wanted to crack it open al

    The Faculty

    not a clue on this one, also from the land between the lakes in Indiana or Kentucky, magnet highly attracted, VERY heavy i cut a sample to send in and was a little surprised when saw..this..made me think of the movie, the faculty. lol

    Please ID

    Hello. My grandmother found this probably in the 1920’s. I have conflicting information. Some say is dinosaur egg, some say sedimentary geode. I must admit it looks nothing like the other geodes she and i collected together but perhaps it is. Thought i could get your opinions on this. Probably found in central texas although she never said where she got it. Thank you for your help. I can take better photos if these not good enough. Just let me know. There are no crystals inside.

    Simple Geode or Geodized Fossil

    A very odd rock found by my wife in Arizona as a child. Exact locality unknown. Lots of textures. There are some pretty long crystals in the cavities. Could this be a geodized fossil? If so, what kind? It doesn’t really look like pictures of geodized cephalopods or crinoids. Thanks!
  17. JordanPS

    Geodized crinoid possibly.

    I believe these are geodized crinoid. Found at my residence in Casey county, Kentucky. I know crinoid are very common and I believe these could all be. I posted on here a month or two ago and have learned a bit since then but I like extra opinions. Thank you

    NM Pennsylvanian

    Hello all I haven't posted in a while. I haven't really been able to get out much for a while, but recently I did find a few (i believe) Composita lying on top the ground just off the road near Albuquerque. Some were complete and some eroded. They seem to be filled with crystals. One in the matrix. I also wanted to show you guys this other fossil in a matrix. A friend was showing me some rocks around her yard when she show me this one. At first I thought it was just a rock with some white inclusions. She liked th
  19. Hi all, I found this in a stream in Eureka, MO, USA. If anyone can help me with identifying, please do!
  20. I have so many rocks that I often like to take one and remove as much matrix as I can, to learn more about it. This rock was very interesting! The limestone was very soft and I know for a fact that I removed plenty of small fossils along the way, but I thought I was digging a geode out of the rock (the "original" thing was the dark area). After cleaning thoroughly with vinegar and a toothbrush, I started removing all soft matrix with a dental pick. I was surprised to "break through" to a totally different geode than the one I thought I was digging out! Part of this new geode broke off late

    Found fossil in a stream in Eureka, Missouri, USA. Does anyone know what the fossil may be?

    Trilobite geode

    Trilobide geode, bought in Morocco from a street vendor. I tend to assume it's real, because nobody would wish to work on a fake for such little money - but I will accept your expert judgement. Size about 6x4cm. If real, what is it?

    East Ks Geodes

    Hey all, I’ve found a number of these pretty geodized shells with incredible smoky and clear quartz crystals in the Kansas City area. Have you guys ever found anything like these?
  24. My wife and I recently traveled to Brown County, Indiana (Nashville) so she could attend a friend's baby shower and, while she was there, I slipped away to check out some local streams for fossils. I remembered finding lots of geodes and crinoids around Lake Monroe (to the west) as a kid attending scout camp so I was hoping I might have similar luck on this trip. I lucked out and the stream I checked had many, MANY geodes and a smattering of crinoids and other fossil material. After doing some searching on this forum and elsewhere online, it seems these geodes are frequently formed around (wit
