    Is this a shark tooth?

    Hello All, New to forum. Could you please help me ID this. Is it a shark tooth? Thank you Mano

    Latest Confusing Find

    Found this today, while on a weekend hunt. Discovered in Hopkins County, edging an old coal mine. I've never seen anything like it before.

    What’s this?

    Pulled this from roughly 3-4 feet deep in my backyard on the far west/nw edge of San Antonio. Found a rock bed as I was digging. Odd because until then the soil was actually soil…it was dark and was easy to shovel. I’ve dug holes all around my property and at many other spots around this area and I’ve always hit a very solid layer of limestone before even getting a foot deep. So 3 feet was noteworthy. And that was about 8 months ago. It took me that amount of time to uncover this one. It’s a hair shy of 2lbs4oz/ just over 1kg. Any thoughts on it?
  4. Fossilsupremacy

    I think i found a sponge or coral?

    New to this platform and web forums in general (other than discord). But uh- i was at Lake Ray Roberts beach yesterday and found this strangely shaped rock in the water that i think might be a sponge or coral due to the abnormal tiny holes in it. I’m no paleontologist but i know that the area used to be underwater, so it would make sense. If anyone can identify these photos, it would be a huge favor (and if you have discord i might draw your fav dino as a reward-) (btw, the fossil’s about 3/4ths the size of my hand, and i’m 5’11.)

    Niobrara Chalk Finds

    Found these three rocks in an outcropping of Niobrara Chalk in Southeast SD. I suspect they are sponges or coral of some kind. Pics 2&3 are both roughly the diameter of a penny, pic 1 is probably 20% larger. ID would be greatly appreciated!

    Niobrara Chalk Sponges?

    Found these five mysteries in an outcropping of Niobrara chalk in southeast SD. I think they resemble sponges or coral, though I'm well aware that they may not be. The four sand-colored ones are all roughly the diameter of a penny, though the first pic is a little larger. The red-stained one is about the diameter of a nickel. Thanks in advance!

    Want fossil IDs from jax beach

    I originally thought the last slide was pieces of coral but couldn’t find similar images. I think the first picture is some kind of tooth on the left and then maybe just a ray plate embedded in rock on the right. Thanks for any help!
  8. What kind of coral is this? I'm not an expert, but just love to explore and found this beautiful thing. I tried to google it but found no match. Any help would be appreciated, thank you!

    Need help to identify

    Location found was Grant NM on the edge of the boundary to Gila National Forest. Hope this helps in it's identification. Thank you. It's dimensions are approximately 8cm x 4cm x 3cm

    ID Assistance

    Hi! Just wanting to see if I can get any IDs on my recent finds from Lake Michigan. Thanks for any help. 1. 2. 3. 4. 5. 6. 7.
  11. Like the title says, I collected this when I was a kid in Woodstock Ontario. Not sure what I'm looking at exactly. I'm thinking the bigger thing is horn coral of some kind?
  12. All collected in gravel and beach rocks from SW Wisconsin. Thanks so much for the help! I love this community:)

    Fossil/mineral ID

    Sorry I’ve been posting a lot but it’s been so exciting finally being able to identify some of my mystery fossils! I got this out of a box of random minerals and fossils at the last chance mine in Creed Colorado but I think they might have been brought from somewhere else but don’t know for sure. My first thought was coral but don’t really know. Thanks ahead of time!

    saskatchwean corals? 2/3

    2/3 found these on shore of Lake Diefenbaker in Saskatchewan, Canada. looked to be eroded from sandy deposits with layers of harder iron-rich rusty strata. the fossils themselves are heavy, mineralized with iron and then rusted? corals? all the same type or different? i think this is in cretaceous age but not sure. see other 2 posts these specimens are larger, very heavy. like solid iron, looks like outer textured surface mineralized and inner cavity separate - looks like central tubular structure did not mineralized (still sandy) in one pic (could scrape out with toothpick)

    saskatchwan coral? 3/3

    3/3 found these on shore of Lake Diefenbaker in Saskatchewan, Canada. looked to be eroded from sandy deposits with layers of harder iron-rich rusty strata. the fossils themselves are heavy, mineralized with iron and then rusted? corals? all the same type or different? i think this is in cretaceous age but not sure. see other 2 posts these samples are really interesting, found in situ, on exposed section of eroding sandy beach cliff - see photos, sand with layers of iron rich strata but these bubble textured rusty iron “tubes” all over, connected and running for long distances

    Missouri Fossil

    Images have the sharpness and definition turned up to hopefully see more detail. I wish I could say the formation but the map I was looking at was particularly large and I just couldn't really tell. All I can say is that all of the possible formations were from the ordovician period. The first rock is 2.54 centimeters wide, and the second is 19.05 centimeters wide. I was thinking that it was a coral maybe? The shape reminds me of brain coral, but I also haven't seen any coral fossils like this one so I don't know. Sorry if the photos are bad, I took them on
  18. My wife and I went out for our third fossil hunting expedition and landed on what I would consider to be our first big find. We went camping up near Ram Falls, in Alberta Canada. I previously read on this handy website that others had found ammonites in the area, specifically scaphite depressus, an low and behold, we found one too! I can't described how pumped I was to hold that thing in my hand. What a great feeling. Anyway, we also found a fair amount of other coral looking thingys, and I would really appreciate some help IDing them. Here they are: I am thinking that these thre
  19. Hi everyone this is Matthew again. Can anyone tell me what kind of coral/sponge this could be ? I found it in the creek today and I have no clue what it is. Here are a few photos:
  20. Hi all! Found in Lansing, NY near Cayuga lake in a drainage wash out but I do not recognize it as a native stone or coming from the formations that I've seen over the past 6 months. I've been on the fence about posting this as I wasn't sure it was a fossil but after getting some decent macro photos, I'm seeing some curious details and I am not sure if this could be a coral or bryozoan colony of some sort or another amazing example of geological wonders. We had major flooding last year, creeks and streams broke their banks, and I found this stuck in a pile of tree trunks 3 feet above the normal
  21. Found near Cayuga Lake on the bank of a tributary. The raised spherical type shapes measure 3 - 4 mm in diameter and can be seen on several sides of the stone. I'm not sure what the matrix is but think it's a type of shale. There are so many types of shale in my area and I have yet to learn how to discern between them. This stone is very hard, dark grey (not quite black) and cannot be fragmented/chipped easily like others I find that can be crumbled in my bare hands. Could this be a coral? My field guide for this area doesn't show any corals that resemble this. I love this one!

    Cretaceous life?

    Most of what I find in southeast Texas is mio-pleistocene, and fresh water based. But at times older cretaceous stuff washes down. Since it's rare here, I'm completely clueless as to differences between oysters, corals, rudists and things but would like to learn more. I found this a while back and it seems to have very distinct patterns on the outside and inside. From searches, I thought maybe a broken piece of rudist, but I wouldn't know one if it bit me. It just doesn't look like normal rock to me. Any guidance would be appreciated. @JohnJ
