    Weirdo 2

    So deciding if this is one thing or two things. I am currently leaning towards it being a skinny coral with burrow/root trace around it. What do you see?
  2. Hello: Would like to know if anyone can help identify the several impressions on the rock in the attached photos? I am guessing that the roundish impression could have been made by a crab shell, but the other one is a mystery. There are also numerous tiny white all over the rock surface and wonder if these were left by small creatures. The "crab shell" measures 1.5 mm across. The other impression measures approx. 4 mm in length and approx. 2 mm tall. It was collected years ago just north of Santa Barbara. Thank you.

    Help Identifying Fossil Impression

    Hello: Would like to know if anyone can help identify the attached fossil image? This fossil impression was collected years ago north of Santa Barbara. The impression measures approx. 10.5 mm long. Thank you.

    Ironstone fossil

    I could probably fill the back of a pickup truck with ironstone I've picked up for closer inspection because it looked like it may have fossil possibilities, have only found a few and this is one. Found in Grayson formation Tarrant co, first thought was ammonite impression but there's a second faint impression on opposite side that doesn't fit with that and the outline isn't right, or am I not imagining the overall shape correctly?

    Nodule #7: Skin impression?

    From the album: Muncie Creek Shale Phosphatic Nodules

    I believe the dark brown may indeed be skin while the blue part is cartilage.

    Trilobite Impression?

    I just found this piece in a parking lot in Ann Arbor, Michigan. The stone was taken from some quarry and dumped here, so there is no geographic or temporal control, but I was wondering if it was a trilobite (since that's what it looks like to me). Thanks!
  7. Upon doing some research on exposures near Great Falls, and from a tip I received from a fellow member of my local prospector's group, I found an exposure just outside of Belt that is somewhat known for its plant fossils. Roadside Geology of Montana has this area of the state marked as early Cretaceous, but the large Jurassic coal seam cutting through the middle of this exposure was apparent as soon as I parked. I scrambled up the loose shale and sandstone to the seam, where I almost immediately began to spot small impressions in the dark-gray shale.

    Ireland Sandstone Ripple Marks

    We found this yesterday outside of Sedan Kansas on a 4-H Geology field trip. It was with a thinner layer of sandstone just below a thick layer of Ireland sandstone. One of the leaders thought it was ripple marks. I also thought it looked like ripple marks but wanted a second opinion. We would hope to be able to display this in her geology exhibit as a fossil if it is truly ripple marks.

    Florissant unknown (fish scale?)

    Hello everybody! I have another U.F.O here (Unidentified Florissant Object) and to be honest, this one has really stumped me! It isn't a carbon stain, it isn't one of those pumice chunks 'fireballs' that are common at Florissant, and it has a strange texture and shape. Weirdly preserved petrified wood? That is my best guess as of now... @piranha @Top Trilo @Tetradium The fossil is 1/2 an inch long. The first 2 pictures are the fossil by itself and the third I circled it. The rest are microscope pics of the texture. Pics 5,6, and 9 show the edges. 7 shows the top.

    Marine Fossil? Impression Fossil?

    Howdy everyone. :-) I think I've gotten a little better at identifying the Pleistocene fossils I've found (and figuring out when an ID is probably hopeless), but on the few things I've found that don't fall into that era, I'm still pretty lost. I found the rock below a while back in a sand and gravel matrix near South Texas. It looks like a regular nondescript rock on its rounded face (top left), but on the flatter face (the other three pictures), it looks like it was cracked open at some point and revealed something. Tiny fin? Leaf? Impression fossil

    Trilobite or Brachiopod Impression?

    Wondering whether this is a trilobite or brachiopod impression. (Hoping its a trilobite.) Found it in a spoil heap at a small outcrop across from Gore Grocery Store, Gore, VA. Outcrop is Devonian in age. Anybody know what formation it is?

    Mystery Chalk Fossil Imprint

    Hello, I went on a walk a few days ago to the local chalk pit and of course couldn't resist spending a few minutes scouting for fossils. This is one of two specimens that I found, the other being a shell fragment. At first I thought the pattern might be formed by ice but I wasn't convinced and kept searching, managing to recover two other small pieces. My suspicion of it not being ice related was confirmed when at the bottom of the slope I found the more complete counter slab, with a layer of ice still covering part of the fossil. Needless to say this made for cold hands on the wal

    impression on pebble

    Heres another. This is some sort of impression? Dunno. Does not look like much can be made from inspecting it but thought someone might find it interesting...or not.

    Hadrosaur Skin Impression

    Hi everyone, Wondering whether or not you think this looks like a Hadro skin impression. Basic Info: South Dakota Hell Creek FM Cretaceous 65 MYO
  15. Good afternoon everyone, I’ve previously seen some skin impressions on the auction site but not one for a low price like this one. However, I have trouble seeing where the scale impressions are on the fossil and was wondering if you guys could make them out, if this even is a skin impression. Fossil is 2.5 cm x 1.5 cm From the Hell Creek Formation near Baker, Montana.

    Micro print fossils

    Found sifting through little flinty pebbles on South Isle of Wight beaches First, which I am most interested in, was actually found by my landlord. He just picked it up saying "a stone in a stone" but I noticed some striations coming out of the hole. So took it home and pulled the smaller stone out and you can see a teardrop shaped impression with radial striation and pimple markings. Impression is 10mm long by 6mm wide. Second is just a band of tiny circlish markings 3.5x2mm. Third is a little hole with vertical r

    This is a very strange rock.

    Hello, I found this very strange rock. It has what looks like a fossil impression? And this strange hole that has scale-like structures in it. Is anybody able to tell me anything about this? Sorry there's no scale, I couldn't find a ruler. It's about 10cm long. I found it in Northamptonshire, UK. Thanks.
  18. Hello! I see this skin impression. What do you think about quality? Is a skin impression or mummy skin? The seller told me that belong to Kritosaurus. Thank you so much.
  19. This looks too clean to be real, especially considering all the frog fossils I see are of bones only. If this isn't a natural formation, how in the heck was this done? Cause it looks like real rock at the very least to me, and the negative impression itself does look natural(the edges of the frog features look weathered), apart from the incredible detail. Sorry if this is obviously fake, I don't think I've ever looked at more than a couple fossils in my entire life :/

    Hadrosaur Skin Impression

    Isolated piece of hadrosaur skin. Likely Edmontosaurus.
  22. Hey guys new here. Bought this item at an antique store and it looks authentic at some points but not at others. The amount of detail makes me think it is too real to be a replica. Let me know what you think.

    Unknown Thing....Probably Geological

    I've been digging through an old stash of fossils I collected years ago, and came across this thing. I seem to remember finding it about 20 years ago whilst out walking in North East Wales, UK. It is quite lightweight for the size, and makes a very different sound compared to the dull thud of a rock, when tapped with a fingernail. There also appears to be some sort of impression prominent on the "inside" curve. I expect this to be something geological (or even archaeological), but on the off-chance anyone has an inkling what it might be, you'd b

    Impression in amber

    Yes, you read that right. I have a piece of amber with an impression, not an inclusion. I got a small order of Indonesian amber in on Monday & 1 piece had an interesting impression. The size of the impression is 2.5 cm wide x 3 cm tall & curved in an almost 1/2 circle as you will see by the pics. I'm seeing what appears to be a leaf of some sort, veins & all. I've never heard of an impression in amber before, not saying they don't exist, just that I had never heard of one. Indonesian amber is Early Miocene @ 10 to 23 MYO if that helps any. Pics 1 & 2 show the impression, 3 &
  25. thinking these may be a pair of really worn starfish impressions not sure I caught the right light to see the impressions though found in gravel load from West of Houston Texas from Brazos River.
