The Tracks of Worms -- 35 million years ago!

My friend, Anna Merlini from the Univeristy of Milano, points to the tracks of ancient worms that lived in the muds of a shallow sea about 35 million years ago. These muds became rocks, and the rocks are now found alongside the road leading to the village of Dotsikos.

Worms have no skeletons, and thus cannot become fossils. Only their burrows and tracks are preserved. The muds of ancient Dotsikos must have been a paradise for the worms of the past!
