  1. I’m very curious about these “ripple marks” that I have seen posted a few times on the forum. From what little research I have been able to do (so far...) they seem to be caused by wind or water erosion of the rock. However, there is mention of them possibly being fossilized rippled sediment from the floor of a body of water. So... are these geological erosions or some type of fossilized evidence of water movement? I can see how the erosion would work, but wouldn’t the sediment be compressed during lithification/fossilization and destroy the details if it was from a body of water

    Shiny gold clam? What is this??

    Finally got around to my bucket of unwashed rocks and discovered this. Don't know what to make of it, it's either Cretaceous or from QAL. It was so pretty wet I put a flat clear coat on the top side to bring out contrasting colors, bottom and side are natural. Kinda looks bonyish or turtlish heck I don't know!
  3. I am just stumped on these. All came from banks of canal at the bottom of a hill. These are all on the shallow level side of canal amongst sandstone, and they are everywhere. On other side of canal a little further down it's grey clay with big red concretions and fossils shown but these aren't present. These whatever they are aren't very heavy but hard like limestone. Only found one with inclusion, and broke one open and it's smooth. Included pictures of both. They kinda stick to tongue.
  4. The KYANA Geological Society is hosting their annual mineral, gem, and fossil show next weekend (Nov. 22-24). I attended last year and it is a small, but fun event. I’m not sure which day I will be there, but I plan to take the family. Just passing along the information in case anyone is in the Louisville area and would like to attend. If you can’t make it, don’t worry, I will come back with a full trip report. http://www.kyanageo.org/showflier.htm

    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.

    Possible footprint?

    I’m gonna need some help on this one... I’m not even sure whether it’s a fossil or just geological. Found at Sugar Creek in Crawfordsville, Indiana

    Found this piece while digging into the hillside behind the house near lake Wister in Southeast Oklahoma. The area is primarily Pennsylvanian and I have found some beautiful specimens on the land. There are a lot of limestone and sandstone ledges and outcroppings all over the property. I do t see any tooling marks on the edges so believe the shape is natural but not sure what the texturing is. Any help would be appreciated.

    Oddity is it possibly...

    Hello, I found this at the beginning of 2018 and haven't given it much thought until I saw the post from 2016 about a strange specimen that looked like Native Americans carved. The topic has been linked below. Below is the specimen I found and was curious if its the same process and is also counter septarian? I also thought they might be beekite rings. Any thoughts and ideas would be greatly appreciated. Best regards, Paul
  9. First off, not all the pics do this much justice. Brand new camera & not quite sure on lighting yet. Anyhow, I found this the other night while outside at work. I looked down at the river rock landscaping in this one area & saw what looked like a shadow that was at the wrong angle with the light, so I picked it up. Took it inside & this is what I had found. 4.5 cm long x 4 cm wide x about 1.75 cm thick weighing 27.2 gm. Some of the edge views show what looks like more extending down into whatever the matrix is. It doesn't fizz with hydrogen peroxide. I keep thinking shell when look
  10. Hi all, While sifting for sharks teeth in the pebbles we came across these different looking ‘stones’. The top and bottom specimens are the ones we are questioning. Stones? Seeds? Scute? (Top one). Any help would be welcomed. Thanks in advance

    Cool rock or finally a fossil?

    Again, it's small enough that pics are tricky to get with my phone. I've posted the interesting side, the side, and the flip side. What do you think?
  12. Hey Hi Boys and Girls, Ladies and gentlemen, and all others! I have noticed that the phrase "It is just a rock" is used quite often when a non fossil rock is posted for an ID. I think that this is a bad choice of wording that can cause confusion. Most fossils and all trace fossils can be described as being just a rock also. (lithified life) I humbly request that We refrain from using this terminology to describe a non fossil rock. Regards, Tony

    Coral or Geological?

    Is this a fossil? Or just a rock?
  14. MSirmon


    Found these in the San Angelo formation near Grape Creek, TX. I'm not sure what to make of the (as if that surprises any of the regular contributors in this forum). There were plenty of rocks in the area but these were different than the rest. On the first item the exterior is fairly hard but the interior is softer and disintegrates easily. I'm guessing a softer limestone? The second is is very dense and has similar patterns to the belly of a tortoise or turtle. Any help or direction would be appreciated and thank you for your patience.

    hi guys, would just like to mention again how helpfull and interesting this well run forum is. I am wondering if anybody has an idea what this specimen is ? Location is 'somewhere in australia', from an old collection i aquired, item is 466 grams, and 15cm wide cheers, kevin

    Found this interesting stone with white wavy lines running through it. The lines are not solid but have a segmented look to them, and are slightly raised in texture. It has a somewhat fibrous texture that reminds me of petrified wood, but this looks nothing like the brown or caramel colored jasper-ized wood I find around here. Found in the Palmer Divide area of Colorado, Cretaceous. Is it something interesting, or just a pretty rock? It is about 4 inches square. Thanks for peeking
  17. I'm quite sure all members of the TFF have purchased a book in the past , present and perhaps in the future on topics relating to the geology and the fossils you hope to find in your part of the world. So whose going to finish that book this year and complete the promise you made to yourself. Tell us what your reading....i love a good book. ( I can just see you leaping to your bookcase now ). Regards, D&E

    Another Where Am I

    While returning from another fossil collecting trip, photos posted later, I took a photo of this geological formation. Can you name the site and the state? I'm off to North Dakota, (collecting with FF member Bev is on the agenda) so will check in when I can. PS: Albuquerque Rock and Fossil show is coming the first weekend in October, I'll be there, hope some members will be also. More on this later. Jim Old Dead Things
