    Mosasaur skull piece? Pierre shale sd

    This fossil has many grooves, holes and structures. My only guess is it's a part of a skull of mosasaur or plesiosaur. Any ideas? Or good reference pics of skull parts for comparison? Thanks
  2. Found on surface of field in Eastern Iowa 15 years ago, guessing it may have been carried on a tire from a gravel road, dropped by a human or deposited by glacier. Hard grey limestone. Fine details suggest to me a digit pulled from a carcass & buried. Apparent rodent-like bite marks in both the nail and flesh. This thing is amazing to me but I am having trouble finding much to help identify via internet. Any ideas? Am I imagining things here?

    Mystery Flintstone fossil

    Hi I’m new here. Was given this lump of flint-stone with what was presumed to be an arrowhead wedge inside. Obviously this can’t be correct but it has presented a mystery to us. Can anyone enlighten with an identification of the fossil contained? There are lots of details visible on close inspection. Many thanks!
  4. I’ve had this tiny 1mm shark tooth in my collection for 3 or 4 years and am no closer to knowing what it is than when I got it. The person I got it from had no idea either. I don’t believe it’s batoid, looks shark to me. Again its tiny, roughly 1mm. It stretched the limits on the micro eye it’s so small. It is from the Ampe Clay Pit, Egem. It has some odd asymmetry going on. I have thought perhaps it was an odd Catshark of some sort but I don’t know about that now. Could it be a weird Orectolobiformes of some sort ? I don’t like admitting when I’m clueless but I real

    What is this?

    My partner gave me this Fossil that he found as a child behind his home in Allegany NY in a creek in the early 1990's. No idea what it is or if it is even real.
  7. Hello! New member here. I’m not much of a fossil collector but I have a few I’ve found myself; mostly petrified wood. At a recent gem/mineral/fossil show I won a silent auction lot that had two pieces in it. The main one was a nice branch segment and the second was an odd shaped rock (pictures below). The lot had a piece of paper that just said “petrified wood”. My bid won. No idea where the rock came from originally as it was donated by someone. The second piece doesn’t look like any petrified wood I’ve ever seen. I’m hoping someone can tell me something about what it might be. Th
  8. I received this in small bulk lot owned by a relative of the seller. I am unsure on the location or if the tooth is in fact from a mosasaur. My reasoning for mosasaur is that it lacks serrations and it came with other cretaceous specimens, however the color is off for Morocco which are the specimens I am more familiar with. If it's mosasaur perhaps a location is will be possible as well? Best regards.
  9. Hey there everyone! I haven't been on in some time but I've just started unpacking my stuff from a move and I came across this fossil that I found in the fall of last year. I found it in an eroding gravel cliff that I frequently find Coleraine formation deposits in. This fossil is one of the handful that I haven't been able to identify. Whatever it is, it's one of the larger fossil/casts that I've found. Any help would be appreciated!
  10. Found at the beach yesterday and I am obsessed with this ai can't stop looking at it it seems to be a carved picture or something on top of some Flint stone what could this be?
  11. I found this yesterday on a beach in England it's almost like fairy wings wrapped around a rock any one ever seen anything like this before? And knows what it is

    Hey guys! Mystery fish here. Don’t really know much about it.

    Weird backyard find

    Okay, when I say backyard, actually a creek bed just over the backyard fence. The creek is a main drainage of the Northwest flanks of Mt. Diablo in the SF Bay Area, CA, USA. Every winter rocks and boulders wash down the creek, so I cannot know the specific geological time zone, but we've found other fossils here (future posts coming). Looks like it could be fossil to me, and my imagination leads to thoughts of maybe fish? or mollusk? Figured it'd be worth a shot posting this up to see if anyone sees something identifiable. Thanks in advance! RCD

    Mystery Fish

    I don't really know much about this unfortunately. Not sure where it's from or what it is. Apparently it was collected in the 1940's though which is interesting.
  16. Greetings, this is my first post on this forum! I can typically identify most of my finds using google, but I found an interesting / poorly formed cast, or maybe concretion?, in a shape I hadn't seen before and I have no idea what it is or how to potentially clean it. It seems pretty fragile, and with no idea what I am looking at, I haven't attempted any cleaning. Hoping to find some ideas here! Found in Hays county, TX, presumably part of the Glen rose limestone formation. Came out of a small cliff made from an old small quarry dug out of the side of a hilltop. The limestone

    Mystery Huge Anomalocaris Appendange?

    Hi, I have this mystery piece of what appears to be anomalocarid appendage of sorts. The problem is I did not receive any information with it and it came out of an old collection from Maine, Usa. I'm not to sure what else it could be from the appearance but I am also very uncertain of the exact species. The piece of a very laminated sparkly shale If I had to guess it could've came from either Burgess Shale, Utah, or Nevada but I not sure what locality it could be from so if anyone if familiar with these shales and can tell from the preservation it would be a huge help, thank you and looking fo

    found a bone in my mince

    I found this bone in my mince ('beef') and I couldn't begin trying to ID it. My best guess was a rat's rib but rat ribs don't look quite like this. It's obviously not from a cow, those are enormous. Unless it's an inner ear bone or something? I realize that this is a fossil hunter's forum but it's the nearest thing to my need that I managed to find.

    Strange China fossil/battered tooth

    So, the fellow who I get some of my China pterosaur teeth from has offered me this fossil among a few other worn/battered/partial teeth. He can't place it--says it is possibly a tooth of some kind. It is Jurassic age, from GuangYian City, SiChuan Province. Unfortunately, he doesn;'t know which of the two formations from there it is from. There are two--Shaximiao which is a terrestrial formation and Zhenzhuchong which is mainly marine but has had prosauropod (Lufengosaurus found there). Unfortunately it is in quite a poor condition--but I am hoping someone

    Mystery Specimen ID

    I found a fossil fragment on site the other day unlike anything I have ever come across before. Some ideas that have been suggested by colleagues include a bone fragment, petrified wood, or a bryozoan colony. The fragment is approximately 2.5 cm long and half a cm wide, is Pliocene in age, and comes from the Kaawa Formation for anyone who knows their New Zealand stratigraphy well. Im not looking for an ID as such, more just a general indication of what I'm dealing with from anyone else who has come across something similar. Many thanks!
  23. Hi all, this strange piece came with a batch of edestus fossils that were found in a coal mine in Illinois. Have no idea what it could be, the front seems to be coated in black coal mostly while the back has what appears to be ridges. All I know about the location is it was found in a coal mine along with some edestus teeth that is Carboniferous in age. Hoping with some help to get to the bottom of this mystery.

    Utah - Dinos (Raptor + ?)

    Hello All! Found a pocket of dino in the Moab area of Utah. I'm confident one is a raptor, but I may be wrong. The other I am not sure about. For reference, they were right around the corner from each other in the same pocket. Just a note - these are WAY off the beaten path in an area very few people would be able to get to. Quite frankly I was surprised to find them in this material as opposed to conglomerate like most of my other finds. Thanks in advance for your help! Raptor (?) - The whole thing was there down to the tail, but I am still wor
