TourmalineGuy Posted March 17, 2010 Share Posted March 17, 2010 Will the ever generous fossil forum grant me another wish and give me some advice on the following fossils? I know they're not all identifiable (probably #2 and maybe #3), but I do have some questions. These are all from the Peace River of Florida, so they can be Miocene Marine or Miocene-Pleistocene Land. Or at least that's the most likely, who knows, #1 looks suspiciously like a trilobite... (<---this means I'm just kidding) Onto the fossils: #1: I am posting this one because both sides have a ring on them, its in pretty bad shape. I thought at first it may be a vertebra, but it doesn't look like any I know or have seen. Plus, the disk-shaped sides aren't nearly as regular as most vertebra. Any ideas out there? #2: This is almost certainly an osteoderm or scute, but I don't have great references and I can't figure out exactly to what... The pattern looks a lot like turtle shell, but I haven't seen a piece quite like this. #3: This little bone is half complete. It is very flattened towards the broken end. #4: A hollow bone! Is this a bird bone? I know plenty other fossilized bones can be hollow too... perhaps some insight into telling the differences in your average, half-destroyed fossil? Well that's it, enjoy the fossils. I'll probably have another batch in a couple weeks as I weed through my Peace River scraps.

ozzyrules244 jr Posted March 17, 2010 Share Posted March 17, 2010 #2 is a turtle shell piece #4 is a bird bone lol I cheated and looked at dads bones and turtle shells Link to comment Share on other sites More sharing options...
Auspex Posted March 17, 2010 Share Posted March 17, 2010 #4 may be hollow, but it is rather sturdy for bird.

TourmalineGuy Posted March 17, 2010 Author Share Posted March 17, 2010 Thanks Auspex, I'll stop expecting everything hollow to be bird, I guess Link to comment Share on other sites More sharing options...
Hawkeye Posted March 17, 2010 Share Posted March 17, 2010 I agree that #2 is turtle, looks like one of the points of the carapace where a vertebral process was attached. If you believe everything you read, perhaps it's time for you to stop reading... Link to comment Share on other sites More sharing options...
TourmalineGuy Posted March 17, 2010 Author Share Posted March 17, 2010 Yeah, the turtle piece just seemed odd. Its not symmetrical like the other pieces I have with vertebra attached, nor does the attachment look like a vertebra as in my others. Looking at this image: I can see a few spots that would make sense, so thanks! Does anyone have anything to say for the other two? I'm particular curious if the little bone looks familiar to anyone.

tracer Posted March 17, 2010 Share Posted March 17, 2010 #1 has dished-out side morphology that is reminiscent to me of the structure of an astragalus. not enough there to really say that, but i'm just thinking out loud. #3 looks turtley to me in the morphology. number last seems like it's got the shape of say a deer metapodial diaphysis. don't know. hopefully you take wild guesses under advisement.

TourmalineGuy Posted March 18, 2010 Author Share Posted March 18, 2010 Thanks for taking a look Harry and Tracer, And, yes, I take your wild guesses under advisement. But, I do appreciate them; wild guesses provide a great starting point for further research. And, now that I compare #1 to my deer astragalus, it matches fairly closely, if properly oriented, to one half of it. Although it is roughly 50% larger in the dimensions, so its might be part of a camel/llama astragalus... Even that might be puts my inquisitive soul partially at rest. Thanks for the wild guess.
