  1. 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.
  2. 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
  3. 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.
  4. 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
  5. 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?
  6. 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
  7. 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
  8. 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?
  9. 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
  10. Fossils or just rocks

    Not sure what I found.
  11. 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!
  12. 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.
  13. 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!!
  14. 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
  15. Sphere Rock

    What is this? Perfectly round. Thanks
  16. 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!
  17. Cannot ID what this is

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

    Is this a stromatolite? Or an indian tool?
  19. 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?
  20. 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.
  21. I do not have a lot of experience buying insect fossils and was wondering if this ancestor to the modern dragonfly fossil is real?
  22. Hello I am new to this site and was wondering if anyone could help me identify what this is. While on vacation in Myrtle Beach,SC my 2 year old son found this.We were just walking higher up on the beach and he picked it up. Thanks for help. .
  23. I am looking into buying the fossil shown below and I was wondering if any one can tell if it’s real or fake. I am leaning more towards real, but I would enjoy some second opinions.
  24. Gifted Fossils from South America

    Good Day! These fossils were a gift from a friend in the early 1980's. He was a world traveler and brought them to my family from South America. He has since passed so I can't ask him specifics. Clearly they are fish fossils, but that is all I can derive as a layperson. Are there other things that a more skilled person in the field could relay about them? Thank you for the information. The sizes are on the photos: The larger piece is 14.5 x 4.25 x 4 inches The smaller piece is 5.25 x 6.5 x 3.5 inches They are very heavy.
  25. Interesting fossil/rock

    Hi folks. Found a rock in our pasture, and am wondering about the imprint on the side. A search turned up this forum, and I thought it might interest some of you. I attached 3 pictures. After reading your guidelines I see that it suggests pics from 6 different angles, measurements, etc. At this point I don't have those. If you want them I'll get them over the next few days. The first pic shows my Wife holding the rock. I figured that gives a reasonable sense of scale. The following 2 pictures are of course closer views. The rock was found on a steep hillside in a pasture in Illinois. About 70 miles NE of St. Louis. I assume it was uncovered by erosion. Our soil is not rocky, but rocks of various types turn up from time to time. The boss (my Wife) said it looks like teeth marks. I think it's a tire mark from Fred Flintstone's car. I hope you guys have a sense of humor. And that you can shed some light on just what exactly this is.
