Found under a rock in a former quarry. It posed for a few photographs then disappeared. The rock was put back in place.
No interactions present.
Looks like you also have some shed lizard skin in there too!
There are lizards on the site, but not sure which bit is the lizard skin.
Next to the slow worm's head there is a piece of shed reptile skin, it looks like lizard belly scales
