  1. Petoskey too hard?

    HI there, I recently found a Petoskey Stone among others on the same tiny (12 foot) beach in Mid/Upper Michigan, as I have for years in the same location. Only...this one's different. I can't seem to polish it down entirely by hand OR with a dremel. It has a lot of beveled structure still compared to others I've seen, and it just feels HARD. There also seem to be tiny crystal bits in some places. Can Pestoskey Stones (limestone as I understand it) harden into Travertine or Marble and retain their distinct pattern and shape?
  2. Small conical fossil ID help

    Hello found this in northern Puerto Rico in middle to late oligocene limestone. Measures about 1 cm any ideas on what it is? Thank you!
  3. Fossilzed echinoderm spine?

    Hello, found this in northern Puerto Rico - middle to late oligocene limestone. Am I correct on the ID? thank you
  4. Coral, Burrow or something else?

    Hello, found this in a river in northern Puerto Rico in the Lares Formation - middle to upper Oligocene
  5. Fossil in need of ID

    I found this somewhere near Hancock, MD I think. It was many moons ago, before I knew much about fossils so I don't remember where I found it exactly. It's limestone and I noticed some strange looking things, possibly fossils. Tell me what you guys think, I'd guess Ordovician simply because it seems to contain limestone in that area.
  6. Found in northern Ontario Canada in limestone
  7. what might this be

    Hello, found this in a cut limestone floor plate - I wonder what this might be. I am not a geology expert, I'm a medical researcher. The image is scanned, 10 cm real size. Regards, Alar Aints
  8. teredinidae burrow casts?

    Found these fossil hunting on a small beach in northern puerto rico - lower miocene limestone. are these shipworm fossils? I found the rock with the hole on the same beach. Second picture is the inside of the biggest piece
  9. Brachiopod maybe?

    Hello, another one from Ayios Athanasios hills, 5km from shore, this one I already prepped, it's a bit confusing, at some point there seems to be a shell over a shell, when I tried to prep the inside, there were white and red parts, also a small round shell part, so I stopped till I get your advice. Is it half a brachiopod again or something else? It is white/pearly with light shades of grey as opposed to which was more brown/orange and bigger Here are the photos the size is 38mm from one far side to the other, yet the one side is slightly broken so ...
  10. a pretty bivalvia

    ok location: Ayios athanasios hills, limassol, 8km from shore. i know that Kingdom: Animalia Phylum: Mollusca Class: Bivalvia Order: Pterioida Family: Pectinidae ?? Genus: ?Species: ? But I am also wondering, if it's ok that I will be cleaning the top with a needle, and if I should remove also that bottom coquina matrix? (will i find a pearl hehehe) And can those arc encrusted epibiots also be removed without cracking the shell?
  11. I found, I found!

    Hello people, This and more stuff I found on the hills of Ayios Athanasios, app 10km from the beach. It looks like a shell, or 2 shells, and I think is one of the cases that needs to be cleaned. Any idea how to remove the white stone material without breaking the 'shell' which is brown/orange/yellow colored
  12. Now you see it, now you don't rugged UK Great Oolite landscape on latest SDGS field trip Eomesodon sp tooth ( top tip : look for flies )
  13. Gastropod ID?

    Hello, I found this Gastropod while hammering a chunk of Lower Miocene Limestone at a beach in Northern Puerto Rico. In my opinion it's a nice fossil with some crystallization. The Description from the USGS on the limestone formation is: Hard granular calcarenite overlain by alternating beds of chalky marl and rubbly limestone Just wondering if any one could help me ID it. Thank you!
  14. Insect wing?

    I found this in a gorge near a Wass go Lake New York. The wing-like shape is composed of quartz - we find lots of horn coral in this area so wasn't sure if this could also be an oblique section through some type of coral.
  15. Fossilized Bone??

    Hello, I found this piece today while exploring the beach in Northern Puerto Rico, in Miocene Limestone. Found some coral fossils and lots of molluscs shells. I believe it is a bone, it is very dense and heavy and seems to be fossilized but I am no expert. Please help me ID this piece Thank you! more pictures in next post.
  16. First Official Finds

    Hello, want to share a picture of some of my finds from my first official fossil hunting trip. We explored a the gravel bed of a river which I knew had formed caverns up the stream in the limestone formations. Tertiary Although reaching the actual limestone formations is (probably) impossible, since it's in the middle of the rain forest, as soon as we got there we saw limestone pieces the river had carried down. We started looking and found some really neat ones (picture), in my opinion Top left is a trace fossil, top right is a bivalve with both pieces on! with lots of sediment in the middle. I'm pretty excited to do some more exploring when I get the time! I haven't cleaned them yet, i want to take some of the excess sediment off the fossil but I have to do some more researcher to figure out the best way to do so.
  17. Help ID - possible coral?

    Picture I took while hunting, left the fossil because I did not have the right tools. Limestone - Middle Tertiary through Cretaceous also wanted to share a picture of an eerie rock formation, looks just like the profile of a person really caught my eye thanks for your help!
  18. My boyfriend works in northern Ontario (Canada) at a limestone rock quarry and found this while chipping a piece of rock. I am not sure if this is even a legitimite fossil and if so what kind it is and would love some feedback!
  19. Hey everyone, I've just got back from collecting a ton(literally) of bone valley matrix. The fossils in this matrix will be really colorful and not your typical peace river black. I'm open for anything! You guys don't even have to tell me what your sending, I'll pack a small/medium/large flat rate box(your choice) and ship it out to you. I've already spotted a couple of small megs on the outside of these chunks. Any takers?
  20. Hello there friends, This looks and feels like something to me. The brown material inside is flint, the white is limestone. found on Moni beach any thoughts?
  21. cat's eyes, twins

    Hello I wasn't sure if I should post this in minerals instead, but let's check it out here. Found in Paramali, turtle beach, east of akrotiri area, when facing north. It is obvious that I found the two pieces of a cracked single. The 'eye' shape in 1b, matches the location of the whiter spots inside. Also, the whites inside, are surrounded by small parallel lines. on the photo, they are more visible on the left side, but they exist on both. Something else you can see, is that the 2 external sides are pretty much negative of each other, regarding coloring.
  22. Did I find a Seed Shrimp? Ostracoda?

    This one might be a little hard but I think I found a seed shrimp (Ostracoda) in Limestone formations from middle Tertiary - crustaceous in northen Puerto Rico (sorry I don't know specifics yet) Here are the pictures. I came along some images online that show the same shape as the piece in question. Size ~ 3mm - 3.5mm Thanks for any help!
  23. Northeast missouri coral find

    Hope someone can identify these 2 fossil corals found in limestone in northeast missouri. Thanks!
  24. Help me ID -- middle tertiary

    Hello, I am new to the forum and new to fossil collecting. Last week I was exploring Limestone deposits in northern Puerto Rico. I found some fossils imbedded into the limestone but then I found this piece. From what I understand, this is a fossil bone because of its porous nature. Could anyone tell me what I collected? Thank you for any help! I plan on doing much more research and exploring in the next weeks. Thank you, Miguel
  25. Ok it looks like a prety geological creation, but then there is this (photo 3) is it just a shell mold, or could it be some breathing organ thing, coz it is placed lower. And this (photo 4) that is on the highest of the 3 peaks that are formed and sort of reminds me of a mouth with teeth. Found near akrotiri, ayios ermoyenis - curium area cliffs. Its 25cm long and the center 17cm high, it looks like hmm some sort of triple fin, or fish or exploding angry eel ... something that belongs to the sea anyway some more photos next post
