Dragon I.D.
It looks like a Western Heath Dragon. Species Rankinia adelaidenis, subspecies chapmani. If it was found on the Yorke Peninsular or west of the Yorke Peninsular along the coastal strip all the way to the WA border, then this would be my guess. Otherwise definately a species of Tympanocryptis. There are several species of the Genus Tympanocryptis found in S.A. including the Nullabor earless dragon species Houstoni. This dragon has a range very similar to the Western Heath Dragon. In the far North of the state are the species cephalus, (the pebble mimicking or blotch tailed earless dragon) and centralis (the Centralian earless dragon). The animal in this thread does not look like either of these species so I would rule these two out. The other 3 species of Tympanocryptis found in S.A. are tetraporophora (the long tailed earless dragon) tail is too short in the photo to be this species, intima (the smooth snouted earless dragon) head scales on the animal in the photo are very pronounced so I doubt it is this species and finally, lineata (the lined earless dragon) maybe but I dont think so.
Still think it is either a Western Heath Dragon or a Nullabor Earless Dragon. Could the person who posted this thread send me a PM with their contact details so I can contact them to discuss further. I have a strong interest in small dragon species and would like to follow up this thread please
