  1. My most recent Pierre shale find

    Here’s one a friend and I have been trying to settle for a little while. One end of the argument is that this is an unusual rock carried off the mountains by glaciers. the other end is that this is a heavily eroded bivalve.
  2. Corolla NC beach. Fossil or rock?

    Found this today on the beach in Corolla NC. Fossil? Rock? As always, I am intrigued!
  3. Crystal fossil or just weird formation

    Ok so is this a bug, leaf, pine cone or just random crystal formation. But if not random how does it turn to crystal.
  4. Fossil Identification in Western Wisconsin

    *Higher resolution and many more images linked below to Google Drive for a clear view* Fossil: Large limestone rock containing hundreds of marine fossils and with what appears to be a bone roughly 3cm in diameter. As well what appears to be the remains of other bone structures. Location: Found 10 miles from the Mississippi River near Ellsworth, Wisconsin USA (Western Wisconsin) in a low valley area that looks like an ancient river bed. Rock Measurements: Roughly 15cm x 28cm My Understanding of Geology and Paleontology: 2/10 *There are a vast amount of images so I'd uploaded them to Google Drive in high resolution here: https://drive.google.com/folderview?id=1-QkitLR3bwWFEn0Dh6OoNngsH8F5O31w I found this large limestone rock on our property near what I imagine would be an ancient riverway located at the bottom of a recharge point (aka hill). During heavy rains this area can literally turn in to a river and wash the soil down stream. This rock appears to contain all of the common marine fossils you'd find in Western Wisconsin from what I've researched. However, there's what appears to be a bone or unusual looking aquatic creature near the snail as shown. The snail was extremely well preserved before the vinegar soaking ate the shell and pigment away. A bit more about the location in which it was found; I had been landscaping the slope of the soil for about 2 years in the backyard by shovel. I had lived in this home for about 4 years and I found the soil to be unusual versus any other home I've lived in nearby. The heavy, wet clay soil contained many large green basalt rocks - I'd never seen one before this time. The bedrock is limestone but about 100 FT away the bedrock is sandstone (according to geological maps). The Mississippi river is 10 miles from this location in western Wisconsin near Minnesota. It's also in the path of the "Great Midcontinent Rift" which I find interesting. There are also many large "bluffs" and rolling hills. It's a beautiful area. Anyhow, I'd like to find out what else may be in this rock. It has been in vinegar for about 2-years and is slowly changing shape which in my imagination resembles a skull. I'd like to find a means to protect the exposed fossils while the limestone is absorbing. I had read something about fossil glue or plaster that can protect the exposed fossils while in the acetic acid. This is an educational experiment for me and I've always wanted to learn about paleontology and geology. Any help and identification would be appreciated! There are so many fossils and things to look at in this rock that I uploaded the images to a public folder on Google Drive so that others can view them in a higher resolution. My Galaxy Note 8 is not the best at focusing on close up images so please forgive my photography. If you see something interesting I'd be curious to know! Thanks! -Jack from Western Wisconsin (Google Drive images: https://drive.google.com/folderview?id=1-QkitLR3bwWFEn0Dh6OoNngsH8F5O31w)
  5. Geological or Fossil?

    This came in a big box of mixed fossils. This is an orphan without a label or bag. It looks interesting, like a cross-section of something in the rock matrix. The object is circular in profile and cone or tooth shaped. There appears to be more than one of them, but the other is still partially obscured by matrix. Is this a mineralized fossil of some sort, or is this just a strange geological specimen that got mixed in? Could this be some kind of stromatolite? I wish I had some locality info on it, but I don't. Any help would be appreciated.
  6. Plain ole rock or possible egg?

    I went home to help clean out my family storage unit. While home I found a rock that resembles an egg. I used to do landscaping in Illinois and I believe that's when I found it. I haven't looked at it in over 20 years. When I saw it again it made me curious. The lines on it do look like breakage and the most interesting part to me is that it has indentations on both sides which makes me think it was soft at one point. Also, on the rock seems to be compressed into an elongated shape which coincides with the indentations. Its about 7 inches in width and about 8.5 inches in diameter. It seems to be slightly porous under close examination. The open end leads me to believe that its not an egg but some of the smaller cracks that are raised look similar to shell. I appreciate everyone taking the time to look at it.
  7. Was this rock underwater ?

    In our cottage in an island there are these big rocks that were dug up from the ground when we first built our house but there is one rock in particular that looks like it may have been underwater at some point and I sure am interested in the possibility of maybe finding some fossils, what's your opinion ?does it look like it may have been underwater? And could this area have fossils? Thanks
  8. Is this rock considered a fossil

    So is this rock considered a trace fossil or a fossil at all? I am asking because I have seen similar rocks identified as fossils. Thanks.
  9. Especially inspired by this object: http://www.thefossilforum.com/index.php?/topic/96343-stone-found-on-beach-in-wales/ but also many others posted in the ID section, I would like to discuss the possibility of construction of a flow chart for "object identification". But I don´t know, if this would make any sense or if it could be helpful. Both for the more experienced ID people or for the unexperienced ID people. It don´t need to be detailed, some "end points" I am thinking of are (of course, it can be deepened endlessly!): Artifact (modern, native American, etc.) Fossil (mollusc, tooth, Dino bone, mammal bone etc.) Rock (limestone, granite, schist etc. Concretion (siderite, pyrite, calcite etc...) Mineral (Calcite, Quartz, others etc.) It would be a long and extensive work. But my interest is more general: Is it even possible and does it make sense? Franz Bernhard
  10. 45 year old mystery

    My dad found this on a construction site over 45 years ago and it got stuck in a drawer and never identified. We used to jokingly call it the caveman finger but I’m sure it’s just some sort of geological formation. Any clues?
  11. What is this?

    Hello, I am new to this forum, I just joined today. I am beginning to get an interest in fossils ever since I found one that was in a rock in my backyard. I need some help figuring out what this is. Here are the details. Two years ago, I found a small piece of sedimentary rock by my house, and this rock had petrified wood in it. A friend of mine who was a fossil enthusiast, (and unfortunately passed away last year,) told me that the rock likely was brought in from Bruneau, Idaho, which is near where I live. There are similar rocks there. About a week ago, I was working on getting the petrified wood I saw out of it. I was VERY careful, keep that in mind. The rock split on accident, none of the petrified wood was damaged, but inside where it split was what looked like a shell fossil. I was able to get it out intact, a picture is attached. It is about 2 cm in diameter. My Penpal wants me to figure out what kind of shell fossil it is. Can someone help me identify this? If you need more information, I will get it. Jared
  12. A family member had this sitting next to their fireplace. I am generally clueless, but I'll try and give you as much information as I can. This was found partially buried in central Michigan in a field. There's a lake in the general area. Useful details: Generally bowling ball sized. About 35lb / 15kg, 12" (300mm) or so in the longer dimension. Concrete like feeling to it. It's non-ferrous. For all I know it was some junk leftover from someone pouring a sidewalk, that happened to take an interesting form. Can anyone point me in a good direction of what this is? Let me know if there's any more details that would help, and I can try to answer your question. Slightly bigger images in the imgur link I put below. https://imgur.com/a/SKTFon2
  13. Rock or fossil?

    The more I look at this I just can’t help but think that it is something more than just a pretty rock. What do you guys think?
  14. Is it fossil or rock?

    Hi all! I am completely new to fossil collection, and have started it only because I had an assignment for a class. Now, however,after visiting couple of fossil sites and getting pictures of what I found, I got excited and curious. I searched internet but only get lost. So my main question is whether at least one of my finds is a fossil, or all of them are rocks? Pictures and information about location below. 1. Alki Point, Seattle. Found it in a shale. About 3 cm long 2. Alki Point, Seattle. Found it in shale. White rings in shale about 3 mm in diameter: 3. West coast of Olympic Peninsula,WA found it on the beach near Cape Alava 4 cm wide, 2.5 high 4. Find it near Clallam Bay, WA. 6 cm long, 3 high
  15. Fossils or just rocks

    Not sure what I found.
  16. Found these all laying around the same area by an old creek flowing from the mountains into the Yukon River, Alaska! it was like a nest of them! Lots of round rocks near this creek as well, then angles bedrock surrounding this creek area...the rounder ones are very heavy! Working on better pictures with a scale, weight, etc for identification.... in the upper left hand corner by the hand, the larger dark rock has 'rib' markings as well as the rock below it...then the small rock in the left upper corner by the hand seems to be fossilized bone or tusk... then the smallest round rock in the upper right corner is a smaller version of the larger.... the cross section of the broken one seems to have an outer shell of 1/4" thick shell, BUT..... and there are mineralized deposits on the outside as well as in the cracks of a couple of these...the 'broken' rock in the bottom left is a good example of the mineralization (I'm a sped teacher!, so don't take me to task for my lack of knowledge and terms!) BUT, these will look cool in my sauna!!!! The heavy ones are like cannon balls!
  17. What fossil is this?

    I found this while fishing on the beach if a cove in Massachusetts. It was below a huge rock cliff. Other fossils have been found in the same cove. I don't know what kind of rock the cliff is but this was certainly way different.
  18. i’m pretty sure this is just a cool rock but if any of you think it’s of biological origin... one can only hope!!
  19. Nice crab

    Thanks so much to @steelhead9 for preparing this crab for me, I thought his work was so good that I’d share it with everyone some of the legs are restored and it’s a puliarus vulgaris from washington
  20. Sphere Rock

    What is this? Perfectly round. Thanks
  21. Hello everyone, I'm new to this forum and fossil hunt. I found a fossil in Toronto area near a road construction site. It looks like some kind of insect. May I ask if someone could identify the ID of this fossil for me please? Thank you very much!
  22. Cannot ID what this is

    Hi. I found this in Washington State and I have no idea what this is.
  23. Stromatolite? Indian Tool?

    Is this a stromatolite? Or an indian tool?
  24. Fossil or Rock

    I came across this recently. Looks kind of interesting. I cannot tell if its quartz or what. It is hard. Any chance it could be a fossil?
  25. I am looking into buying one of these parts of a mosasaur jaw and wanted to make sure there real. I believe there is, but getting a second opinion always helps.
