  1. More from Tunkhannock

    I found a few more pieces I wasn’t totally sure about. All came from Tunkhannock, Pa in a mountainous area. All three of these have me stumped. Thanks for the help in advance! First one:
  2. Fossilized bone or odd rock?

    I'm wondering if this is a fossilized bone or just an odd rock I found in the Oquirrh Mountains in Utah? It has a unique convex and concave surface pattern in some areas. The red and white parts of the rock have different textures; the white is very rigid and rough. All the pictures are of the same rock at differing angles. Please share your ideas, thanks!
  3. Is This A Fossil?

    Hello, I would like to know whether or not this is a fossil on top of this rock? Is it just weathering? It is from my yard in middle Tennessee.
  4. found in Hell Creek, MT

    Hi, I have no clue on this one. I was out on private land near Jordan MT. I found this rock which is unlike any other in the area. I spent two days on the property and found nothing else even remotely close to this. The land owner has had several Triceratops and Tyrannosaurus taken from his land. He didn't know what this was either. I thought it might be coprolite but I don't see any chunks of material. It looks like the core is darker with this lighter brown outside. It's relatively dense compared to most of the rocks I was picking up. It's about 7" long and 3.75" wide at base. I am thinking about cutting it. I'd be most appreciative if someone could help. Thanks!! Frank
  5. Ordinary rock or old egg?

    Hello! I'm from Brazil, South America, and live by a beach. I like to walk around the rocks since there are lots of different rocks, and if i start to climb, the "grassy" area is full of sedimentary rocks. I've found this stone, dropped it, it didn't broke in half like other stones do, it released some type of shell (there are 3 pieces on the photos) and showed something like a "inner stone". I know that it's probably nothing since i don't know much about rocks and fossils, but who knows. I never found other rock with this "double layer" here. Thanks for your time!
  6. Weird water worn rock or something else?

    Is this just a water worn rock in a weird pattern, or is it something else? Found at West Runton, UK by my son along with a bucket full of flint rocks and a small handful of belenmites. It’s an intriguing pattern, so even if it’s just a rock I still think it’s neat.
  7. Unknown Fossil

    Hello, I'm new to this site and I don't know much about fossils. I have searched some trying to figure out what this rock is but have found nothing quite like it. If anyone can help me identify this I would greatly appreciate it.
  8. Is this a fossil?

    Is this a fossil or just a rock it just looks odd to me but I have no experience with fossils so I'm not sure it's probably just a rock
  9. Hello, I’m hoping someone can let me know what caused the three indentations in this rock? Weathering? Some type of track? Something previously embedded in the rock?
  10. Tooth?

    Found in the Olympic peninsula, shows what looks like healed cracks, as well as one that only partly healed. Just over two inches long. Any ideas? The picture is on a 3 inch - 5 inch index card.
  11. Is this a fossil?

    Hello, I’m hoping someone will let me know if this rock has some type of fossil in it? I found it in a creek in middle Tennessee. After cleaning it with vinegar and water, several little black spots became visible. Are those fossil imprints of some sort?
  12. Found in my yard while planting

    Hi I was recently doing some planting when I came across this thing. Does anyone know what it could be? Our house was built in 1800 and this was located close to the stonewall that borders our property.
  13. What is it?

    Found in Pennsylvania
  14. What is this fossil?

    Found this in The group near a creek
  15. This rock has so many different formations, like it's been glued together. Can someone tell me how this can be melted in several places with such odd formation?
  16. Fossil or not?

    Hey guys! I hardly know a thing about fossils and it would be great if someone could help me out. My family and I visited Chippoke State Park and found what appears to be either a fossil or just a shell trapped in sand. It’s about 3 and a half inches wide and long. Anything helps. Thanks!
  17. Hello, I have a rather large rock in my yard (middle Tennessee) which I have always thought was interesting. I’m hoping somebody will let me know which type(s) of rock it is? It has gray and white crystals(?) of some sort on top, along with white streaks running through it. It also has several knobby areas. Are these chert nodules? Any information is appreciated. Thanks!
  18. Possible Paw Track?

    I’m hoping someone can tell me if this is a paw track of some sort? There are three indentations on this rock of very similar shape and size. (four inches wide) Or would it have been impossible for this type of rock to have had any tyoe of tracks? The rock was in my barn in middle Tennessee. Thanks.
  19. Fossil or strange rocks?

    I was walking on the beach in Cape Charles, VA and both of these ‘rocks’ turned up in the surf together. I feel like they may be fossils but I am not sure so I am turning to you experts ;-) If they are not fossils then are they bone or just very strange rocks?!? Thank you!!
  20. Oddly shaped rock or fossil?

    I’m hoping someone will let me know if this is “just” a rock, or possibly a coprolite of some sort? It seems to have different textures and layers. Thanks!
  21. Marks in limestone rock

    What makes Mark's like these in limestone? There r three rows in this three inch limestone. Thanks for helping railguy
  22. Fossilized Wood or Stone?

    I found this in a creek in middle Tennessee. I’m wondering if it is just a rock or if it could be petrified wood? Thanks!
  23. Fossilized Fish?

    I’m hoping someone can tell me which type of fossils are in this rock. I found it in my yard in middle Tennessee. There are several crushed shells visible, but I’m especially wondering about the areas circled in red. The area circled in the third picture almost looks like a fish? The smaller circled area appears hollow. I’m not sure of what that could be. Any ideas? Thanks!
  24. Rock formation?

    I found this one in Kansas. I have no clue if it's just a odd rock formation or what. Thought I would share
  25. Fossil or rock?

    Believe this one was found in Kansas. Is this bone or fossil??
