Field Notes
Description:
These are trace fossils - so called because they are traces or tracks left by animals rather than their body. Imagine a worm that lived millions of years ago in the Sulurian Period and the sand it burrowed through was turned to rock and the burrows remained as tubes in the rock.
Habitat:
Kalbarri on the seashore
