  1. Past hour
  2. Genuine specimen but quite badly prepped. It is interesting to find that most Saurichyths specimens are incomplete, possibly due to the very delicate body. More complete specimens are sometimes found in unprepped plates that are in "soft" matrix. See the following for comparison.

    Miocene fish?

    @cck better pics and close ups would help to solve the problem. Bones could look like rocks and rocks like bones. But, bones could be identified by their fine structure, and rocks too. So, detailed pics of the surface could help. Thanks!
  4. Just like what you said its up to you and what you like. Some people don't mind it but some people do. There are plenty of spino teeth out there it just comes down to how patient you are to find exactly what you want and, obviously, how much space you have for the ever growing collection.
  5. Interesting. If you find this topic on the Forum again, can you please link it here in the replies ? I want to read the replies and want to know what other people thought about it.

    Miocene fish?

    I was going to suggest better pictures early in the conversation last night until I saw this and figured we were just wasting our time in responding: I don't ever want to see someone leave over an ID but, if he's already made that choice, nothing I say is going to change that.

    Mazon Creek Tree Bark?

    Why siderite ? It is rather a mineral (thus able to crystallize and having a determined chemical formula) than a rock. Coco

    Maybe A Mosasaur? Micro from Central Texas

    The carina looks like it has thickened enamel. I’ve seen some fish teeth with this similar feature.

    Is there a bird in this rock?

    I agree with the above statements. Maybe the OP would like to thank us for our input

    Fossil Coprolites

    Not seeing anything to suggest that this is a coprolite.

    Fossil Coprolites

    No
  15. Like @FB003 I also feel like I’ve seen this tooth before. Coco

    Fossil Coprolites

    Hi, Could we have some text ? ! Place of origin, size etc... What could we find coprolites of this size in the Cambrian ? Coco

    Miocene fish?

    I agree with Tim. There can be a big gap in how a piece (whether it's bone, rock,...) strikes you between holding it in your hands and feeling it compared to seeing a picture (of mediocre quality) of it. Let's start this topic over with better pictures and re-evaluate, keeping the above in mind. Then at least the forum's opinion would be based on better quality material and in the best case a friendly discussion ensues. Just my two cents.

    Is there a bird in this rock?

    As others have said, just a suggestively shaped rock

    Miocene fish?

    Well, this can accour naturally too. When you go to any river, you'll find maybe hundreds of similarly shaped rocks there. Might be a bit rarer, but yours dont look that much the same, many differences can be spotted. Also, when I look at most of them, I see no evidence of bone, scales, and teeth. So no fish or something else But thats not a good reason to leave, you've done so much good work here. Do you really want to leave, just because you're not happy with the ID of something ? Sometimes, you have to accept the hard truth.

    My Mazon Creek finds

    Nice finds. The Mazopherusa prinosi is stunning!
  22. Thanks ! Tooth is real, but a bit of work was done on it. Like on most Spino teeth. Is it still worth getting it for the collection tho ? I know, my choice, but I like to have the opinions on it from you guys.

    Shark tooth Id

    In my opinion, they are so badly worn that they can't be positively identified.
  24. This is a very vague question… not entirely sure what you’re looking for. You’ve got about a third of the US in your title. Articulated crinoids are generally rare but can be locally abundant. I have a number of sites in the Midwest that reliably produce specimens, but they took a lot of leg work to find. You just need to put in the work yourself, I doubt anyone is going to hand out sites, especially for fossils with commercial value. Plus the research is half the fun.

    Some paint added

    In original, tail was hard to see when it was different color than rest of the animal and same than the platform. Now it has better balance.
