Auspex Posted November 30, 2010 Share Posted November 30, 2010 The middle three pics remind me of turtle material...

Xiphactinus Posted November 30, 2010 Share Posted November 30, 2010 The first 2 look like some bone fragment. I can't really ID past that. The next is as Auspex said turtle shell. The final doesn't look like a fossil to me... Stonecarver, can you give us a little more info? Where were these found? Do you know the rock formation by chance? That will help with the ID.

ohiofossilhunter Posted November 30, 2010 Share Posted November 30, 2010 1. maybe bone? 2. turtle scute/shell 3. iron stone concetration? Link to comment Share on other sites More sharing options...
dinodigger Posted November 30, 2010 Share Posted November 30, 2010 The interesting pattern looks a lot like Acipenser material we've been collecting in the Eocene. Doesn't appear to be turtle, could be, but I'm guessing Acipenser Sturgeon; Permian amphib skulls have similar patterns too.

tracer Posted November 30, 2010 Share Posted November 30, 2010 the pattern on sturgeon looks to be the reverse of turtle - looking like raised "islands" instead of depressed "dimples". but on all these types of patterned bone, it is my understanding that the pattern is there due to direct skin attachment to the bone without muscle in between. this is why it isn't that common on all kinds of bone, because most bones usually are surrounded by muscles, not skin directly. and so the "dimpled" turtle shell is from soft-shelled turtles with flexible skin on their shell as opposed to the "regular" turtles with keratin covering the shell. sturgeon Link to comment Share on other sites More sharing options...

Thank you for responding, These came from Utah. I have no further information for them, I am sorry about the poor pics, the first one is defenatly part of a foot or toes as there is webbing between the toes. I wll try to post a better photo as that is the one I am most intrested in. Link to comment Share on other sites More sharing options...
stonecarver Posted December 3, 2010 Author Share Posted December 3, 2010 Thanks to everyone for looking at these, I hope these are better photos, Link to comment Share on other sites More sharing options...
Terry Dactyll Posted December 3, 2010 Share Posted December 3, 2010 Stonecarver.... I think its some geological phenomena resulting from bioturbation maybe a worm burrow cast... I can see what your thinking but if the bone of the foot preserved why would the skin to create the webbing... Cheers Steve... And Welcome if your a New Member...

Xiphactinus Posted December 3, 2010 Share Posted December 3, 2010 Stonecarver - thanks for the better pix. The first is 100% turtle shell. The second...I'm not sure about. It's definitely not a foot. You'd see individual bones that aren't there. Having seen the better photos, I'm kind of leaning with Terry that it's not a fossil but a geologic formation. I don't see bone.

bear-dog Posted December 3, 2010 Share Posted December 3, 2010 In your second photo ,the second picture is a turtle scute as well.We find them in our area all the time,so much so I dont pick any up.If you look on the back side [what you thought was the skin side]you will see a pattern.The pattern can tell you what kind of turtle it came from.
