The vast beaches of Gotland are covered with an abundance of fossils. Here are a few which I picked yesterday on a nearby beach..
In fact the entire island of Gotland is built from fossils. Of these petrified animals we know about 1.500 different species trilobites on this island. They are about 400 million years old! 
I just wonder just what these small creatures from the beginning of creation really are ..
Ancestors of plankton, shrimps, mussles , corals and crawfish?
Most probably.
In the old days the long Silurian period was in as a matter of fact called Gotlandikum!
