Looks like the right sort of lizard to me. Plus a sign in the area mentioned that breed. There were two sorts, smaller goldy coloured that were about 7-10cm, and the larger darker coloured ones, which were about 15-20cm.

Measurements are very approximate.

Haven't read the book, or seen the TV series, but hope to experience both one day. It was my knowledge of both that made me want to visit the place.
