  1. Sorry that I don't have details of this specimen's provenance, but I'm trying to help an older friend remember what exactly this is a fossil of. They've had it for over 20 years, and believe they may have acquired it from online auction site in its early days. All I've been able to determine so far is that it is likely a dinosaur tibia. He's quite a fan of hadrosaurs, but I really have no idea if it's possibly from one. It's a fairly large specimen, about 26 in/66 cm long and 5 in/12.7 cm wide at the widest point: I know this is quite challenging without supporting information, but unfortunately any information related to this is missing, and was likely lost in a house fire that occurred years ago. Just hoping to get lucky and see if anyone has any sort of insight. Other photos attached (sorry that they seem to just be rendered full sized without a smaller preview, though that's more of a form limitation than my doing). Thanks..
  2. Posts of my trip to Oklahoma this week had some unidentified fossils shown. Hope was that someone would mention the identity of the specimens. Since no one did, today I am attaching photos of unknowns from the Viola Formation, Ordovician found south of Sulphur, OK. Maybe @crinus is knowledgeable! Could they be something like Evactinopora?
  3. Rara

    Found a strange one today.

    It was difficult to get a good photo. I brushed this untill I could see more. Found by blue river Kansas city. Is it an AMMONITE? It's sort of shaped like one very worn one. Not sure any help would be appreciated. Thx
  4. I found this today while out side on a river bed. The part i found it at is usually not seen & covered by water but the river is unusually dry so i found it on an exposed part. I’ve tried reverse image search & using a rock identifier but can’t find anything that looks similar besides other kinds of fossils. I’m really interested in learning what it is!!! i live in southern minnesota.

    Help me identify this please!!!

    Hello! So I found this back in 2006 while swimming in my local park in Alabama. I felt it under my feet in the mud and could tell it didn’t feel normal, I reached down and pulled this crazy looking thing out, i don’t know if it is wood or bone, the shape on the tip is what sparks my curiosity!!! Thanks in advance!
  6. I recently inherited my great uncles small fossil collection and rock collection. I spent a lot of time with him and can identify most of what I have because he loved to pull them out and show them to me throughout the years. But I have two that I have never seen before. I’m not sure if they are even fossils. I’ve been to a lot of museums and to dinosaur National park many times with him but I have never seen anything like either of these. Unfortunately, I don’t know where he got them. He traveled all over the world and spent much of his retired years traveling so I wouldn’t even be able to guess where they came from. I apologize for that. The first one is almost like a crystal. You can almost see through it but it has the pattern of reptile skin. The second one I took pictures of both sides and a close up of it because I don’t even know how to describe it. Any help you can give me would be appreciated. Thank you

    SedonaAZ

    Found at about 6,000 ft above sea level, although the pic appears to stick up, it is an imprint. Each imprint is approximately 1/2” deep (5 holes total), found in a piece of mudflat. You can see my hand in the right side for scale purposes. Any information is appreciated.
  8. Hello, I wanted to see if anyone would be able to identify this fossil I found in Clarington Ohio. I know it's a coral and I know it's a bryozoan and I'm suspecting it's a Rhombopora however I'm willing to look into any of the species you guys can offer! Thanks for your help. (The fossil in question is roughly an inch long if you're wondering)
  9. looks like shell or kidney? or big beans?

    multicolor spots that 'bloom' on wood?

    Going through my bucket of unknowns and no better way to describe this. Found in creek with mix of Cretateous and alluvial deposits. Originally thought it was wood, not so sure now, I've never seen these spots before that look like they're floating. So tiny hard to get clear pics of the white spots that look like a flower opening and some of the spots appear to be holes at the surface. Must be biological in nature I'm thinking but what? It's pretty whatever it is.

    Big tooth !

    Hello, i saw this absolutely massive tooth for sale today. The finding location is unknown, but it reminds me a bit of Suchomimus, but its way to big. Maybe a sperm whale tooth ? Maybe someone can tell from the pictures which animal this tooth belongs to.
  12. Hello all! We have these small fossils from the Yorktown Formation that we are not sure what they are. They fizzle under HCl! Any help would be appreciated. BTW, the divisions on the scale bar are 5mm. Thanks so much! Miguel M

    Is this a fossilized bird skull?

    Does anyone know what this is? Fossil is about 2" long. Found in Washington.

    unknown fossil, some help needed

    Hi, Can anyone help me to identify this fossil? I thought of a sponge. Unfortunately the location and era are unknown. Vincent

    Bryozoan+Starfish?

    Hello, This is another old collection piece without provenance, and I was hoping someone could tell me if they recognize anything or guess its age. It's a plate of bryozoans, but I think I see a couple starfish peeking out from underneath.

    Can someone identify this tooth ?

    Hello , I have this Basilosaurus tooth in my collection and found today something very interesting in the surrounding matrix : a tooth ! But from what ? I've prepped it a little bit to have a better Look at it . Can someone identify it maybe ?
  17. I brought out a bag of Devonian brachiopods from the Cerro Gordo to clean up this week when I noticed this unknown in amongst the shells. At first I thought geologic but if you look close, it appears to have six sided symmetry. So is this some sort of echinoderm??

    Buying Undescribed Fossils

    If you buy an undescribed fossil do you thing you have donate it to like a museum or something and have the study it and If it is a completely new species you can get it named after you?

    Burlington Bone?

    @CabinetOfCuriosities recently posted a Devonian bone for identification. Having just read the post, I headed downstairs and split open a piece of matrix from the fish layer of the upper Burlington, lower Keokuk Formation and a boney looking fossil presented itself. What a coincidence! It vaguely mimics turtle remains I have found in Florida. Thoughts of what this is are welcomed!!!!!! By the way, the size is 2.5 by 2.0 cm.

    Another Burlington Unknown

    Here is another black mass that emerged from the light colored matrix of the Burlington Formation. Pareidolia has me envisioning a tooth with the enamel peeled away on top and side projections. If it wasn't so fragile, I would prep around the other side. This measures just under 2 cm.

    An Inoceramid morning and a mystery

    Set out yesterday morning to dig up seedling blue bonnets in area by a gulley I hunt, haven't been there for a year so thought I'd check it out before it started raining. I think this is an outcrop of Britton formation, Eagle Ford. Didn't get far before it started raining so basically filled my bag with globs of clay for most part then proceeded to clog up bathtub washing it all off. Pretty happy with results, wish I could find whole ammonites the preservation is so good, was tickled with two Inoceramus that had some shell. So mystery #1, I'm stumped and afraid to chip at any more not knowing the rest of shape. #2, not sure if the piece of shell is related, looks an awful lot like a ptychodus tooth but I'm sure it's something boring Threw in last one just curious what it could be.
