  1. Is it coral or a flower?

    My Dad was given a few slabs of this rock from a friend in Phoenix, AZ. We can’t figure out what it is. Similar to coral fossils but they aren’t circle in shape. When he cut and polished it, it was really hard. Any ideas?
  2. Rapp beach hunting

    Headed to the beach hoping the weatherman was right and could get to the edge of the shells piled at the shoreline just out of reach. The wind was predicted from the SW, but was calm then switched to the NE, and the tide stopped falling. The temperature stayed about 5 degrees lower than predicted as well. Couldn't get to the line of shells where I expected the bigger teeth should be, but with the wind causing a slow wash, teeth started appearing and I got a good variety, colorful and in good shape, though no big ones (and no cowshark, think I lost one in the wash). Will post the whale vertebra tomorrow after it dries. Weather is supposed to be warm tomorrow, may try another beach.
  3. Moroccan Mystery - Coral or Brach?

    Hi all, I just got back from Arizona where I spent a couple of days at the Tucson Gem Show. On my quest for coprolite treasure at the Moroccan village, I came across this little mystery piece. I'm assuming it is some type of coral or brachiopod. The dealer only had a handful of these and this one had the least damage. Can anyone identify it? Any guesses on the age? When I first saw it, it reminded me of the septarians in this thread. Obviously, they are not the same.
  4. Missouri marine fossil ID

    Hello, In my third mystery find around the Kansas City and Blue Springs, MO areas I found these specimens. And I have yet been able to find any photos on the internet that can come close to their character. Can anyone identify what are these tiny egg-like beads? I hope my photos help. Thanks for your attention.
  5. Rugose Coral

    All, I went fossil hunting at a new site a little north of downtown Nashville and hit paydirt with these large pieces of rock; they are absolutely packed full of rugose coral
  6. Coral

    I've not been able to find a comparable coral to this guy. I'm pretty sure it's coral, anyway. Lol Any of you know what it is? Devonian, Sylvania, Ohio. Thanks!
  7. Missouri marine fossil ID

    Hello, I live near west Jackson County, Missouri. I found this fossil while I was walking my dog. It was part of the landscaping for the front of a building that has been there for 20 years or more. No one knows the origin of the material for the landscaping. Lots of reading, I found most of the chert in the landscaping has crinoids as a point of the time period, Devonian? Can't find any photos to compare it with on the internet, been trying for 2 months, a crash course on paleontology 101. I see Missouri in a different light from it all. Can this be identified? Thanks for the opportunity to share.
  8. Silurian Sponge? Coral?

    Hello, I can't seem to ID this fossil found in Silurian reef rock, Chicago area. I made some slices. Any help appreciated.
  9. Cretaceous Halysites?

    Is this a chain coral between the sutures of the ammonite Metoicoceras? About 4mm long (photo taken thru microscope). From the Cretaceous (Cenomanian) Tropic Shale in Utah.
  10. I have another oddity here. Found on a Tampa Bay beach in Florida. It is about 3 inches long, brittle but light weight and hollow, with one end open and one end sealed. The side hole or spout attaches to the larger opening. I did some research and it resembles a calcareous sponge. Is it a sponge? Is it a fossil or modern? Thanks as always to a great group of people! Please see 5 pics below.
  11. Hi, I have a good selection of self-found Devonian aged marine fossils from Ontario, Canada that I am offereing to trade for shark teeth. I have; -several species of brachiopods -a few species of gastropods -ammonites -corals -Bryozoa -trilobites -and more All of my specimens are self-found and many are identified to genus or species. I can provide detailed location and age data with the specimens. Also, I have lots of photos available upon request, but here are a few to give you and idea. i am looking for shark teeth, especially; -interesting Cretaceous teeth -Carcharocles -Carcharodon and/or cospopolitodus -Cretoxyrhina, Cardabiodon, Dwardius -Palaeocarcharodon -Leptostyrax -Ctetodus -interesting locations -anything else interesting Thanks for looking!
  12. Hi all! While I was looking through some of my fossils, I came across the specimen below, and I think it's a new little coral for me! Does anyone have an idea as to its identity? It appears to be a tabulate coral, but if anyone could let me know its genus and species then I'd be much obliged! It's from Hungry Hollow near Arkona, Ontario, Canada (mid-Devonian in age). Thanks in advance for your help! Monica
  13. Florida Agatized Sponge or Coral?

    I found this awesome glittery piece on the beach in Tampa Bay. It is kind of layered and has a cheesecloth pattern on it. It is about 2 x 2 1/2 inches in diameter and about 1 1/4 inches in height. It is lighter than my typical coral finds. It has what looks like 2 bore holes that go right through. I'm not seeing any corallites so I'm leaning towards a sponge. I have 3 photos-- top/bottom and one side view. (Note: photos don't capture the crystallization) What do you think it is? Thanks in advance.
  14. Hi everyone, I've been picking up these beautiful little pieces of coral on Myrtle Beach. I assumed they were fossils, but after reading a lot on the Internet, I'm confused. Some sites call them "agatized," others call them stony coral and say they aren't fossils, lots of sites just refer to them as coral fossils. What throws me is that their white and cream colors are unlike the black of the other fossils I find, and the small pieces of bryozoan I find on the beach are all dull gray. And some seem to be attached to a piece of modern shell. I really appreciate your help. - Paula
  15. bumpy stubby wood or coral?

    coral wood or something else? found west of Houston in a gravel load from the Brazos River I have taken the pics in two different lights, this what ever it is seemed out of place only one like it in the location that I could find... could be a fragment of something larger I don't know.
  16. Coral head ID,

    With the Peace river a bit too high to fossil hunt, I have been heading to some of my other favorite jaunts...there is a little stream ( only 2 feet wide) that meanders through Lee County just a little north of the Caloosahatchee - it probably feeds into another larger creek, though I haven't bothered finding it ...at any rate, with permission, I have hunted it for a few years now. This however is the first interesting coral head I found there. It is like iron...i know the coloration is from exposure, but the coral itself is extremely hard...those top edges are sharp like kiives. It seems to be part of a larger globular coral, as the inside/bottom has that tell tale curvature to it. I have included a closeup of the septa on the bottom, but on the top they are so deep as to not be seen...just that honeycomb effect. is that because the septa are softer and worn out, or were they naturally recessive in this type of coral...and of course, can someone tell me what it is.
  17. I've resisted posting this one because it's so common on Myrtle Beach, I figured I'd be able to research it myself. But hours later, I still am not sure what to call this. Thank you!
  18. Rugose coral??

    Hello: My father in law had these specimens in a drawer and we were trying to identify. He worked all over the country so there is not telling about the location. My internet sleuthing says rugose coral? Thanks for any input.
  19. I found this unusual finger-like fossil on a Tampa Bay beach in Florida. It's about 3 inches long by 1 1/4 inch wide. It has an oval indention with swirls on the end, that looks like an external bivalve mold. The finger-like piece has corallite markings on it. Is this a mold of a shell or a fossilized coral finger? Thanks!
  20. Tooth or Coral? Holderness Coast

    We had a trip to the Holderness.WeI usually only collect Ammonites and the odd bit of bone. The Holderness coast has lots of different corals that come from the boulder clay and if our bag is empty we may take a bit of coral for the garden Anyhow... I found this, at 1st I though tooth, then thought horn coral and discarded it, walked away a few paces, turned round walked back and picked it up again! Though maybe its a tooth, maybe its a coral.... LOL this has gone on for days!!! So over to the experts. I have only ever found teeth as part of a ichthyosaur Jaw, so actually have no idea what a single tooth should look like.
  21. Hello, I am new to the forum and know little to nothing about fossils so forgive me if my guesses are off base. I found this fossil (?) in the river bed of the Frio River in the Texas Hill Country (Real County) north west of San Antonio. It is approximately 2 inches long. Thanks to this forum and googling, I'm wondering if this is either rugose coral or heliophyllum coral? Thanks for any info.
  22. Any insights on this rock

    My sons and I found this rock on the shores of Lake Erie near Point Pelee on the Canadian shores. Doubt it’s anything too special, but it’s by far the largest cluster of fossils we’ve ever found. If anyone has any insights it would be appreciated. My sons really want to know more about it. Thanks in advance. If there is interest I can post pictures that are closer up.
  23. Is this a type of coral?

    Something I've found around Clear Creek while hiking. Any ideas as to what this might be? Obviously some sort of shell, but from when?
  24. Sponges?

    These are all over our desert property in southeastern Cali. Various shapes, sizes, textures, and colors but I grouped some similarly textured ones for this photo. The ones pictured in the group are all lightweight with the texture of coral but we have many others with the same shapes & paisley-like designs (hard to see in photos) but made of smoother rock. I thought for a long time the pink thing in the last set of photos was someone's old spilled paint. It's about 12" wide. Any ideas?
  25. Silicate veins in coral?

    I found these in Lubbock, TX in an area having lots of ammonite fossils. These feel more like a skeleton of silica or something. And they have a blueish tint. Any ideas?
