Very unlikely. needs better proofs ... and they need also to review the concept of fibrocartilage, that shows very similar rings, in animals not suspicious at all of having a reptilian metabolism or cold blood (Like, for example: humans). The main problem could be trying too hard to milk a poor sample. If this animal was cold blooded, why the other goats and sheep living in bad places didn't developed a similar system? We have lots of sheep races selected for very poor environments. We fully explored their different genetic possibilities... nobody has seen a "crocodile like" sheep in the whole planet
