One of my friends stumbled upon this half part of an animal. It seems lizard-like...I don't think I've ever seen a lizard that large, though. We live in Greece. Can you figure it out? Close-up and a zoomed-out version with the pavement in it for scale included (length was ~10-15cm / 4-6 inches).
My guess is the ocellated skink (Chalcides ocellatus).

The species is names for its black/white ocellated, or eye-like, patched scales, similar to the ones seen in you specimen. C. ocellatus also would match your size (15-30 cm) and your location (generalist, including rocky).
It is found throughout the Mediterranean including in Greece.
