Broad Headed Skink

Cool! Glad you could ID it. They can be tricky.

Thanks you both! I found a more focused picture on my camera (still need to upload), and I could count five of the scales under the ridge.

It look similar to an adult female Five-lined skink. It could also be a female Broad-headed skink. They look similar:
