Official Explanations

[OFSO]

Bones, including skulls, belonging to several adults of both sexes, plus one or more children, were discovered at the weekend on the rocks at the end of Roses (Spain) beach. One explanation offered by the authorities is that "they may have been in possession of a medical student who threw them away after his studies were finished." (Quote, El Punt newspaper, today).

Well, that's solved then: no cause for concern.
