John, Apart from the caudal scales, everything about seems to me to be a Jacky Lizard. I agree that most Jackys do not have raised caudal scales, but I am inclined to think this is likely just a variation. GeoffR
Look at the throat and lateral scales. This is a typical juvenile Pogona, even if the enlarged caudal scales seem extreme. There may be some condition effecting it. A quick look at the Jacky lizards drew my attention to another Pogona. I will draw attention to it for your comments.
