    Fossilized heart?

    Found in NORTH CENTRAL MISSOURI, USA My mom and my nephew found this "rock" a few years ago. I was telling my mom about this group, she asked me to post this here. She's wondered for years if it could potentially be a Petrified heart, it has what appears to be valves on it. She doesn't know who she would contact to find out if it is a Petrified heart, so if anyone knows who to contact about this, we'd appreciate it. It weighs 1.92lbs. Thought you guys would think it was cool.

    Nice petrified wood find

    Found this nice little piece while rock hounding last weekend...just wanted to share...

    Petrified or concretion?

    Hey guys I found this in a dried up creek bed right above where a dam had been. The location was in Sandia, Texas. Very close to the mathis lake state park. I've done some research but I' be had it about 4 or five yrs now and would love an opinion from someone that has had experience in this field. I think it's a petrified peach half. What do y'all think?

    Is this fossilized honeycomb

    I found this on a river bank in Louisiana. I've had it for years. I'm not sure what it really is. I would like to know though so I decided to ask this forum. Please help if you can. Thanks. compressor (1).zip
  5. Found in Blount County Alabama near the Blackburn’s Fork of the Locust Fork River
  6. So, I was hanging fossils on my wall. I’ll post a picture of that later. I happened to grab a piece of petrified wood, when I noticed something I didn’t notice before. There were tunnels inside the petrified wood. One tunnel goes clear to the other side of the wood. You can see through it. That is the first discovery. Not sure if that’s caused by a prehistoric tree parasite or something else. Second discovery, on September 11, 2020, I discovered a large piece of Coprolite in Kemmerer Wyoming. Not sure if I spelled that correctly. Many people here and at the quarry said it was turtle Coprolite. However, today, I discovered what looks like bones inside it. It didn’t break, a small piece chipped away, revealing this. This may actually be crocodilian Coprolite. I’m not sure, though. Pictures are attached. You can see the tunnel in the petrified wood and the black spots in the Coprolite that are suspected bones. Anyway, I thought this would catch everyone’s interest. I wanted to share it. Jared
  7. Going through a forgotten corner of the basement last night I stumbled upon a box with some of my grandfather's "rocks" that my grandmother gave me when she sold her house and moved in with my mom a few years ago. As far as we (my grandmother, mom, and myself) know these were all found in Maryland. He worked for the state dot for years as a bridge inspector so they could be from anywhere in the state. The lighter 2 pieces I am confident that they are petrified wood, the brown/red looking one I am not as sure. The brown/red piece's outside is almost like spaghetti noodles laying tight against each other for lack of a better description.

    Reptile heads or rocks?

    So over the last few years I've collected different rocks, fossils, and anything else I find that i think is unique. Eventually, I go through them and have a closer look. I'm sure my eyes are making things up, but, hey, why go om wondering when I can just ask?? I have some rocks here some found in Indiana and some in Ohio and I'm wondering if they are reptile heads of some sort(I'm assuming that's a thing people actually find lol) If you tell me they are rocks, I will believe they are rocks and will appreciate the knowledge. Thank you in advance! You guys rock(yes, pun intended)! Oh, and these are between a half inch to a little over an inch.

    Is this Petrified Wood?

    Is this petrified wood?
  10. I found this tooth that looks petrified while digging a garden in NC, USA. It appears to have cavities. I cannot find a tooth of a dog, wolf or bear that looks similar. The tooth is wider than most K9 teeth photos I’ve seen online. Any ideas of origin and estimate age would be greatly appreciated if visually identifiable.

    Amazing Pertified Creatures

    I found these petrified specimens on private land in the northwest part of San Antonio, Texas over the last 10 months. I did little, if any digging, as recent rain has exposed them. I'm here to learn about the science, as well as what I have in my possession. They are beautiful creatures whom appear to have been frozen in time. What exactly are they and how did they end up in this state of condition. I'm excited to hear you responses as I am new to this "world of fossils" but a willing participant. Thanks for letting me take part.

    Coprolite or just rock?

    Is this a coprolite or just rock? There is something in the center that goes all the way through.

    Is this just a rock or a petrified walnut?

    I thought this was just a rock but I saw in a book this could be a walnut. Any ideas?

    South Texas Petrified Wood

    Was recently driving through Live Oak County in South Texas when I picked up this piece of petrified wood. Not new to collecting but this is my first post. Please go easy on me. I am glad to find this site. Question: Can the type of wood be distinguished from the bark on this piece? The pattern looks so familiar to me but I can’t place it. It appears that the images are too large so I will post others in a reply to my message? Thanks in advance

    Petrified coconut?

    Does anybody know what these are? Size and shape of coconuts embedded into rock on the coast, but hard like stone or petrified wood.
  16. Offered through the link is one of our occasional interactions with someone who is either trolling TFF (great sport, apparently), or somewhat overwhelmed with runaway pareidolia. Our responses are also typical of how TFF works; presentations of the facts without any mockery or derision. We are here to help anyone seeking answers that are within our sphere of knowledge, but sometimes logic cannot prevail. >LINK<

    Petrified plant or just rock?

    My wife found this along the Brazos River. There are white lines that go through the rock from one side to the other. Interestingly, some of the white lines have black lines within them. Any ideas what this is?

    Dorset Petrified Wood

    Found this sticking out of a mud slide near Golden Cap on the Dorset coast. Certainly looks like wood, it doesn’t feel as hard as stone but harder than wood, I suppose like coal. Is it definitely petrified and is anyone able to speculate on age, possible species etc? Thank you in advance

    Petrified/Fossilized Nutshell

    Found out near a dry lake by Barstow, CA. I was wondering if anyone could help ID this piece, it’d be very much appreciated. I’m only able to provide one photo, so hopefully it’s enough.

    Some type of bone?

    Found this piece at China Lake, CA on private property in a large deposit. Only removed this one piece for identification, can anyone help ID this specimen? Can provide more images if possible.

    Need help with ID please...

    I’m in the twilight zone apparently...I know how ridiculous this seems, but the only thing I can find that remotely seems to match this thing for size and shape is titanaboa. I’m open to other suggestions. This was in my back yard in Fort Worth, Texas...relatively shallow - about a foot to the top of it. We are in a rocky area and are within 30 ft of the highest elevation in the county, about 150 ft above the average for the city. I can’t find a tape measure to put next to it, but measured with my iPhone and it’s 29” long, 13” wide, and about 9” at the highest point. Seems to weigh in the 80-100 lb range. It looks like were other At least 2 other snakes on top of it that you can make out on the top left of it, but pieces of them have broken off as well as some of the main specimen. The underbelly is in excellent condition...it seems clearly show “snakeskin”. It wouldn’t let me attach more pictures, but on the back you can clearly see vertebrae at almost the center position and what seems to be some other type of nerve endings above that. There are literally hundreds, maybe thousands of pieces in the immediate area from ground level down ranging from quarter sized up to basketball sized with most between golf ball and baseball. I’ve been digging slowly for 3 days with no end in sight. Many of them are hard to specifically identify but seem to almost all meet criteria for fossil and not rock. Please help...

    Help ID of Petrified plant/wood?

    This piece was found in the same stream bed that I have collected petrified wood from. The area in south of the Dinosaur Park in Laurel MD, the stream runs though College Park MD and is close to areas where foot prints of Cretaceous dinosaurs have been found.

    Could this be petrified wood?

    I have had this rock with my mineral collection for a while and have always wondered if it could be wood. It has a gold sheen to it, especially when wet. I can't remember where I found it.
  24. Does anyone know if this could be bone or petrified wood?
