It doesn't look right to me. 

I know different torts have different numbers of scutes, and the bony under scute skeleton is different but there don't seem enough here and the marginals are weird too.

This is a tortoise ::D

Maybe the 1st one is a prehistoric soccer ball.. T-Rex had to have something to do when not eating everything in sight. :D

The 2nd one looks painted.

Both not real imho.

You may have a look to papers of Dr. M. MAISCH et al., you may find a lot of examples how they're looking...

What about this one?  It’s said that no repair has been done.  Is it a genuine fossil tortoise?

 

The plastron seems real enough but I'm not sure about the carapace. 

The sort of brown lines showing scute position seem to be painted on over a rather odd looking osteoderm/ bone structure.

On the carapace of the first and third specimens there seem to be 2 sets of suture lines between the scutes. I do believe the fossils are real, but I think the thicker, darker sutures on the carapace of both were engraved and painted, and I can't imagine why.

Could the thinner lines be compression cracks with the thicker the actual bone boundaries? There's not much compression evident in the pictures and there's no side view to look for this but it's possible. The thinner lines look too random to my eye to be the actual suture lines.

These appear to be small tortoises.  I suspect that the mystery lines are simply stains where the scutes started to pull away from the carapace bones.  I have no similar tortoise to gauge a match to the scute pattern, but it's my best guess based on a water turtle's scute/bone overlap.
