Does the preservation of the outer bone surface mean
it's possible that this was a dinosaur that lived,
what was it, eight million years after the k-t
boundary?  Is there any way that this is a Cretaceous
fossil that has shown up in a Paleocene deposit?

And what does this mean about the other fossils that
have shown up above the k-t bondary?  Does it require
a re-evaluation?
