It seems it was harder than I thought.
You are right that the section shows an eye and that the animal is something for the herpetologist.
But sea turtles are not typically encountered in the waters of the inner North Sea. To my knowledge the nearest other places in Europe where sea turtles are more regularly sighted are the waters around Ireland and the British west coast. And the nearest breeding grounds in Europe are in the Mediterranean.
I think you were misled by my info where I found it.
Well, I wouldn´t have expected it there either. But from further reading I´ve learned that sandy areas are quite its natural habitat. In addition this animal is running on all of its four legs and not hopping as one would expect from its kind. That night it was running across our path and we first thought of a mouse or vole. Disturbed by our torch light it ran to a little slope nearby where it rapidly digged a hole into the sand with its hindlegs shovelling the sand onto its back and thus burying itself. Well, even this I wouldn´t have expected from an animal of its kind. Isn´t that a bit itchy when having such a moist and sticky skin?
Obviously not! The little feller seemed to feel quite fine in his crumbs.
It´s a toad, called Natterjack Toad in English, more internationally its Latin name is
Bufo calamita, syn.
Epidalea calamita.

P. S. Gee, uploaded and on my LCD the picture looks rubbish again.
It looked much better on my CRT, though. What does it look like on your monitor?
(Nah, I'm betting on the turtle, too.
