Huh?
Please elaborate.
Afaik certain fossils of e.g. sea lilies were thought to have been created by lightning, which is why they were called "Hexenpfennige" (witch pennies) by the people of the time.
Truth is that the lime sediments containing those fossils are harder than the surrounding sand stone and withstood erosion better, and stood out of the landscape. Which is why they were more often hit by lightning.
