  1. Hello, this is my first post. I recently found this rock and was wondering what these impressions might be. It was found in landscaping near Ooltewah, TN, just north of Chattanooga (the property owner gave me permission to collect it). Are these burrows or traces of something else? I found something similar here, but I didn't see an ID. As an aside, would you crack it open (or saw it), or leave it as is?

    Fossil worm burrows

    Hi all I found this today on rt51 between Anna and Carbondale in southern Illinois. Can anyone tell me if I'm right thinking they are work burrows or something else Thank you
  3. CrumpRocks

    Super unique rock

    So I found this rock/fossil and am not sure what it is. I thought it could be worm holes or burrows but I'm not really sure. It also has a loose rock on the inside of it which is pretty cool. Is this sedimentary as well?

    Ball's Falls, Ontario ichnofossil

    A member of our local rockhound club gave me this piece at the recent meeting. The only info she could provide is what's written on the label stuck to the bottom: Ball's Falls, Vineland, Ontario. Thankfully I have that particular bit of info. Can any of you Ontario folks fill me in on any of the other stuff? I gather from basic geo maps that it's from the Lockport Group (Silurian)... any way to determine the formation and which slice of the Silurian?

    What kind of burrows are these?

    I found these burrows in Ordovician-Silurian rocks in Waukesha Wisconsin. I found hundreds of these just a few weeks ago in Green Bay WI (Ordovician) any way to identify what animal made these burrows? Thanks! ps: so sorry I forgot the scale

    Asterosoma?

    Found in Crane Hill, AL (Carboniferous) Could the (presumed) burrows be part of an Asterosoma sp? Thanks for looking
  8. Hi! Looking for help with IDs & also What is this type of fossil called (counter-impression? cast?). Specimen from Crane Hill, Alabama. Thanks for looking Pics 1-plate overview- several potential invertebrates? 2- Potential invertebrate? Some of my newbie guesses: Trilobite (side view) Eurypterid- can’t find definitive info about if locale only had the giant type Crinoid (eg saggital view) Bryzoan Gooseneck barnacle- not sure when these appeared 3- same critter, different angle 4-other invertebrates? 5-stellate shaped imprint? 6-another area of plate showing black ‘spots’ 7-black ‘spots’ look angular, maybe cubic) on high power. No idea if or how this helps, but I wanted to see if it was mold (seems less likely). Included pic for fun (apologies for the quality).

    Is it fossils or geological formations

    Can anyone tell me if these are actual fossils or just geological formations, although they look like fossilize plants to me, it would be very surprising to find fossilized plants from the late Ordovician period. both rocks were found in the Nicolet River Formation on the banks of the Richelieu river

    Florida Mysteries

    Here is (hopefully) one last post to help me identify some items I found while searching through the micro matrix from a Gainesville creek that Ken @digit was nice enough take us to. Some other items have been covered in previous posts:; http://www.thefossilforum.com/index.php?/topic/119097-gainesville-shark-teeth-question/&tab=comments#comment-1305867 http://www.thefossilforum.com/index.php?/topic/114209-north-florida-fun/&tab=comments#comment-1264293 The matrix comes from a creek in Gainesville, Florida and most of the fossils are from the Miocene aged Hawthorn Formation although there is occasional younger material. The fossil fauna is dominated by shark and ray teeth but there are lots of other items including: bivalves, gastropods, crab claws, fish parts, etc. (i.e. marine). What I have below are several items that I am uncertain about and hopefully someone can confirm my suspicion or give me a better idea. Thanks in advance for all your help. Item #1 is what I assume is a fish scale. Is that correct and can it be ID'd any more specifically? Item #2 is are two very tiny beautiful ray tooth. They look different from most of the Dasyatis and Rhynchobatus that I found with a much wider root. That had me thinking Rhinobatus but I'm not really seeing the uvula that I should expect so I could be way off. Any thoughts? Item #3 are a group of fish vertebrae. The two bottom rows are two views of the same 6 vertebrae and I have no doubt they are fish. It is the one on the top that I am uncertain about as it has a totally different shape. But I'm not that familiar with all the different permutations of fish vertebrae, so it may just be a different one. It reminds me of a mammal atlas, but maybe fish atlas bones look like that too. Item #4 are some items that I really have no idea. They look like little sacs and some are broken so that one can see sediment on the interior. While there is variability, most of them have a distinctive teardrop shape. Item #5 I am guessing may be burrow casts, but I'm not sure. Do they look familiar to anyone? Item #6 also look like casts of something, I'm just not sure what. They are generally very straight sections of a smooth tube form. All of the mollusk remains I have found are internal casts so no shell material is generally preserved in this deposit. Item #7 are, I don't know. My Paleozoic brain wants to call them eroded horn corals but I obviously know that is not right. Don't have another option in mind. And lastly, item #8 are probably worm tubes, just looking to see if that is right. They also have a common shape of being U-shaped or looped. They are not attached to a shell or anything (except maybe some matrix) like I am used to seeing with worm tubes. So that is my collection of oddities. I'd appreciate any thoughts folk have. Thanks Mike

    Devonian Burrows? Fish Poo?

    ID help please! I recently found these strange features in a Devonian rock in Johnson County, Iowa. They are unusual looking enough that I suspect an animal may have been involved in their formation. My first guess was that they were burrows that had filled in with dense crinoid and shell debris, but I'm not sure how that would happen. My second guess was that it could be poop/coprolite from a fish or some other Devonian creature. I didn't have a scale with me, but these would be very large for fish poop. I will post another photo in a separate post below (files are too big). I would be very grateful for any assistance, thank you! Here is a link to a video that may also be helpful:

    Trace Fossils from Miocene Potomac

    Hi, longtime lurker first time poster here. I was wondering if you guys can help me ID this concretion my family found years ago near Calvert. I believe it might be a trace fossil of some kind, possibly a burrow or tunnel. I have found similar types at Westmoreland State Park. I can upload pictures from different angles if needed. Any suggestions of what it could be?

  14. Hi friends, I have several of these fossils. I think they look like some sort of worm fossil but can't find anything on the internet similar for comparison. I really don't think it is trilobite tracks because it is deeper. Sorry, I could only get 2 of my pictures to upload. Thanks so much, I would really appreciate any info.
