Clam Fossil (Reversing Poem)

The texture of sandpaper against your fingertips,
Rough and unforgiving.
It resembles a newly cemented driveway,
A clean grey.
Clamped shut the two shells meet,
Mimicking a frightened armadillo.

The clam fossil is a guardian,
Protecting its pearl.
From year to century it is now,
Frozen in stone.
The pearl protected from year to century.
The fossil that was found,
On Kairakau beach ground.
