Fall River County SD Bone

[svcgoat]

Received a few months back in a box of unprepped material unsure what it is exactly.

 

50mm long

@Troodon @jpc any help would be appreciated 

[Troodon]

Not Dinosaur, mostly Fox Hill and Pierre Shale Fm. in that part of SD.   Guess Croc.

[svcgoat]

Is that Cretaceous? @Troodon

[Troodon]

Yes but Marine

There is also Morrison in Fall River County.  

The texture in the first photo looks pretty diagnostic, but can we see pix from the other four angles... think of it as in a box.  You have shown pix from two sides of the box; I have no idea for example, how thick it is.  

[svcgoat]

I may have the county incorrect as that's where the seller lives but don't recall the exact county if it was different I sent a message to the seller. Will send other photo angles when I get home

@jpc

All other sides 

[jpc]

Thanks for the photos...it is very thin.   I am going to say a piece of soft-shelled turtle based on the patterns in the first photo and it consistent thin-ness.  I am not sure there are any  

[svcgoat]

Great thank you it's a nice piece.

@Troodon @jpc So I was compeletely wrong about the county

 

Its Perkins County SD, Hell Creek formation

[jpc]

Oh, that makes it much better.  Soft shell pieces would be surprising in Fall River Co.  Hell Creek Fm, though, soft shell chunks are amongst the most common fossils.
