  1. Unknown tooth/claw

    I saw this item for sale. The dealer calls it "unknown tooth or ck=law. Dino? Sadly, no provenance information is offered. It appears to be agatized. There are a few cracks that may have been repaired, but it doesn't appear frankenstinian. What are folks' thoughts on legitimacy as well as ID? thanks
  2. Is this agatized coral?

    I wish I could recall for sure where I found this. Most of my collection is from tide pools and coves on the West coast of the US but it could possibly be from Zion National Park in Utah, Kern River in CA, or a number of other places but those listed are most likely. It’s porous, lighter and slightly warmer than stone. The dark red areas are striated and softer than the rest. It does resemble some photos I’ve seen of agatized red horn coral, but I’m not sure. Any ideas or suggestions are welcome.
  3. Agatized Stromatolite?

    Looking for ID help. This potential fossil was found on a dry lake bed in Southwest WI. In the same area this was found, I found other "classic" limestone Ordovician stromatolites exhibiting typical lateral columnar stratification in side view with convex tops and concave bottoms. This fossil has much the of the same structures but is partially "agatized". Could it be a stromatolite? All ID feedback will be appreciated.
  4. Coral or bone?

    Found in Cincinnati, Ohio during a parking lot excavation. I know very little about fossils. This is some sort of organic material. Porous, agatized with a bone fragment that looks like a tooth (last photo) in one of the holes. Please advise, Thank you.
  5. Hi again. Some more goodies I can't identify from my mojave desert property. Any help would be greatly appreciated. The wooden slats on my table are about 3" each, for size reference. This first one is heavy, white part is quartz. About 4".

  10. Florida Agatized Coral?

    Hello everyone. Does anyone here do any hunting for agatized coral? My girlfriend loves crystals and I would like to take her on a agatized coral geod hunt. Her and I are brand new to fossil hunting and rock hounding so we have very little experience. In researching the subject I found that the popular sites to find these are the Suwanee river, Withlacoochee river, and Econfina river. Can anyone provide me with any information on the subject. Also, I know that it is a lot to ask but if anyone hunts for these regularly and wouldn't mind a couple tagging along to learn the ropes that would be amazing. Jimmy
  11. Greetings. I have a lot of photos I’d like to share and get some feedback on, assuming there is not a unanimous agreement that the specimens you see in this photo are purely Geological in origin... I found them, and many more, within the geographical boundaries of a Jurassic age rock formation in Northern California that is listed primarily as meta volcanic rocks. Considering that information, please tell me if you thinking I’m barking up an imaginary tree here... If you are uncertain, let me know, and I will post more pictures... Thanks for your time! -Quinn
  12. Agatized Coral?

    This is an interesting shape find. It is about 1 1/2" at it's widest point. It has a round crater in the middle with coral polyps marks and circular bands around it. I see microcrystalline when exposed to the sunlight. I think I found this on one of the small islands in Dunedin Florida, boating. I've seen many forms of corals but I never seen one like this. What do the experts think? Thanks!
  13. My agatized "knuckle bone" fossil

    Hi everyone, I was given this fossil from a friend. It came out if a collection that was given to him by a friend. I'm assuming it is a form of sea life as there were other shell fossils with it. If you hold it up to a flashlight the light passes through it and illuminates it. My friend does not know anything about it. Can u please help me identify it? Thank you!
  14. Crystal agate fossil?

    I found this today on the beach under a clay cliff, it is known for agate And chalcedony to be found on this beach, what would I call this, it looks like some sort of a bone maybe?
  15. Anyone have any idea what these are or what they belonged to? We went digging recently in a newly caved in embankment in the side of a small lake in cass county, NE. We were looking for agates, but found these instead. I don't know anything about fossils, really so all help is appreciated!! Thank you!!! https://goo.gl/photos/vCe1hRzFvQ8x1CrH9
  16. Unidentified agate bone

    From the album Naughtistic fossils and rocks

    Not sure what this bone is from but appears to be a "gem" bone.
  17. Coral ID

    I have collected lots of coral from southwest South Dakota. I believe the majority is horn coral. Despite having a few publications and checking the web, I have several I'm not sure of. A lot of what I find looks agatized. I have attached a photo of what I am guessing is chaetetes coral? Would ove some input. If if someone can suggest a listing of Fossil coral, sponges and Bryozoans with detailed photos or identification, I'd appreciate it. I feel like I have an idea on most of it, just not 100%. Many Thanks!
  18. Agatized Siderastrea

    My brother found this in the lower suwannee limestone formation. It's 17" in diameter and weighs 67lbs.
  19. Agatized Coral - November 2016

    Thought I'd share my prettiest find yet. I'm a newbie but love looking for the agatized coral especially. Through research I was able to find some spots. I have now collected many beautiful pieces however this one is my best yet. I go every weekend in search. The picture doesn't do the piece justice. The smaller piece looks a lot pinker than the picture show. 14997469_1161248773961367_5297713581180059648_n.mp4
  20. This is from Western South Dakota. It is definitely a bone. It is super heavy and it feels like weighs well over 20 lbs. The "tip" has a hole going into the rest cavity of the bone that is all agatized. My foot in the photos is a size 12 men's to give a perspective on the size of it. What kind bone is it? And also what might it be worth?
  21. Is This Agatized Coral?

    I found this on Grand Cayman in an area that had been filled with rock that had probably been mined from a quarry on the interior of the island. It looks like a portion of large Geode but I don't know much about the topic and was hoping to have it identified. I didn't have a ruler so I put it on a piece of paper for scale, the 8.5" side of the paper runs along the bottom. Thanks for any help!
  22. Hello, fossil hunters! A couple years back I found some agatized coral at honeymoon island, and I found one piece that looked like a relatively complete coral head. I could tell that it was partly agatized, so a couple of months ago I decided to cut the thing open with a rock saw I borrowed from my university geology lab. I was wondering if it would be possible to identify the species of coral...I might try to send some of these pictures to someone that specializes in Florida corals. Also, it looks like a clam bored into the coral head. I went back to Honeymoon Island recently, but I didn't have much luck. It might be getting hunted out, but maybe the area just needs a good storm to wash up some new specimens. I cut the coral head into 4 pieces, here are the results-
