I live in the same anoxic conditions
As the Eocene fish.

It helps keep predators at bay, the toxic
Water at the bottom of a shallow sea.

Right next to me in time,
They came alive, ate various things, swam.

At the end, they sank slowly, perhaps twitching,
Until they were under the dead blanket layer

My small flesh is crystallizing,
Not eaten, not decayed, but awaiting a static burial

From billions, I found just those five
And the future declared the site for fish, and my own fossil.
