  1. Shell

    I found a shell that is all grey rock. I would like to know what animal it is. I found it with a bunch of crinoid fossils. I think it's a shell.
  2. Is this an egg or just a round rock?
  3. South central Kansas

    I'm trying to clean the limestone and loose sediment off this speciman. I'm not sure if I am wasting my time. Or if this is a fossil. I'm a novice hoping to find a cool fossil, but old enough to admit failure, if this isn't a fossil. Please help. To me, (the inexperienced novice) lol. It looks like a small skull and neck vertebra of a iguana type??
  4. round something about 4 inches across

    I dont know much about this or where it was found as it was in a closet in a house my friend bought. its not perfectly round or I would say billiard ball...lol...I am thinking its marble or quartz but on the slim chance I posted it here.
  5. could this be a tooth?

    found this it really does resemble a tooth but the root is a bit thick....is this a tooth or a piece of petrified wood?. quarter for size comparison.
  6. partial crab or?

    partial crab or ? it is a dark blue color..the coin is a quarter. mmmm look at the rich creamy center...lol...well looks that way anyway.
  7. Is this anything other than a rock?

    Gday all, was wondering if this was an egg or a rock? I found it on a beach in Australia near the border of south Australia and Victoria when I was a kid, I cut it in half and just forgot about it for around 20 years!
  8. this one is really weird, I think it may be a rolled up something not sure what...any ideas?.
  9. Petrified wood or rock

    Hey all you wonderful folks... I have had this rather heavy piece of what I think is petrified wood for a few years... I found it in outside of jasper park ( Alberta Canada) along a river area or in British Columbia area again along a river I can’t remember which... I was excited when I found it because it looks sooo unique and it is quite heavy for its size my would be a lb or lb and half... any way so I am really looking at it today and now I am questioning if she is petrified wood lol please help me I “wood” (aha) appreciate it. Thank you
  10. Unique Rock - Fossil, or just cool?

    This is my first thread, but hopefully not my last. I have always loved picking up unique rocks ever since childhood, but only occasionally finding an obvious fossil. As an adult, I purchased my first home in southern Michigan, which I believe sits atop a moraine. This "moraine" is a 5 acre pile of sand, rocks, and boulders which rises about 40 feet higher than the surrounding fields. A few weeks ago, I found the pictured stone poking out of one of the slopes. I am fascinated by it, and am curious what it could be. The stone is triangular, approximately 20" long and 10" thick. The greenish layer visible is only a couple inches thick, with the remainder resembling a red granite. Aside from the organic feel, I am particularly fascinated by the 5" leaf shape on top with the "Z" inside of it. I just can't picture this being the result of rock formation/erosion. Thanks for any help!
  11. Weirdest looking rock or?

    This came from Binghamton New York, had it given to me and I’m not really sure if it’s a fossil or just a really oddly shaped rock lol What do you guys think???
  12. Tooth or Rock

    Was down at Big Brook NJ today and came across this specimen. Looking for some help in identifying what I actually have. Is it a rock or a fossil. If the latter is it a tooth?
  13. Hello everyone, I am in desperate need of help with a huge debate I have been having with a friend over fossils preserved in ironstone concretions. From some of what I had read to some advice from other members I it possible to find vertebrate bone among shells and other mollusks preserved in an ironstone concretion. Whether it leaves a trace of the organism, morphs the organic material into the structure of the iron concretion through the decomposition with preserving, or whatever else it may be it seems to be possible. So recently I have hunted a place known to have recorded marine cretaceous shell and other mollusk found in ironstone concretion as well as cretaceous plants in shale, it seems like not to vast of enough study has been done there only from what I know, but since no vertebrate material had yet been discovered there though there can maybe be the possibility. I found these two particularly distinct pieces in iron concretions that exactly mimic the scute structure of soft shell turtle and croc in my opinion, I know how iron concretions are famous for leaving psuedofossils and such but these two pieces look way to exact and since its possible for shells and mollusks to preserve why not scutes? So I am here looking to end this debate, I'm looking for your opinion, can these be labeled as fossils, traces, etc? Or are these among some of the world's best iron concretions and nothing more. Your input especially if you are very experience in this subject would be tremendously appreciated.
  14. Hello everybody, my son just found this out on a farmers field in Denmark. To me it looks like a rock but he in convinced it’s a dinosaur tooth, he is only 4 so I have gone along with it, but it does look very much like a tooth. So so what do you think, just a strange shaped rock or could something be in it? Can only upload 2 pics so sorry for that. Thanks
  15. British Columbia rock or bone

    Hello, I was out walking literally in the middle of nowhere near Jarray, British columbia. There were many different rock out crops and cliffs so i decided to have a peak around. Eventually I came to a hill littered with tens of thousands of rock chunks. Then this guy caught my eye, nothing else in the area even remotely resembled the porous characteristic of this specimen. So I was curious on your thoughts whether this could be bone or just a run of the mill porous rock? Thanks!
  16. Identification please!

    I've had been in possession of this for almost 20 years now and never knew for certain if it was just a rock or if it was a fossil. I unfortunately do not remember how I even obtained it since it was so long ago so I don't know where it originated from. Any insight into what it is will be greatly appreciated!! It's about 3.5 cm x 3 cm.
  17. So, this showed up on a site I visit from time to time. Quite the awesome fossil fish. It never ceases to amaze me what people believe to be fossils.
  18. Is this a rock or an egg?

    Hello all! I’m new here and extremely new to fossils! Today, we went fossil hunting in Walton-on-the-Naze in Essex, England. It’s not far from where we live and is known to be one of the best places in the UK for fossils (particularly the teeth of megalodoms). Anyhow, I found this item and wonder if it’s an egg or a rock. It is relatively small, just under 3 inches long. It feels substantial in weight, 137g, and has cracks and pours. Please see the attached photos Location information: The fossiliferous clays and sands exposed in The Naze area belong to the London Clay and Red Crag formations, and provide evidence of prehistoric life and conditions 54 million years ago (mya) and c.2.5 mya respectively. Fossils occur commonly throughout both formations attracting international interest since the 19th century.
  19. Rock or Fossil?

    Hello, I am hoping somebody will tell me whether or not this is a fossil. It was embedded in layers of a larger rock (from my yard in middle Tennessee) and appears to be a different color than the surrounding rock. It broke away from the area circled in the last picture.
  20. 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:
  21. 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!
  22. 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.
  23. 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
  24. 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!
  25. 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.
