An explosion of life
Came rushing from simple designs.
The bomb had gone off.
Continents joined and divided
Sculpting the landscape above and below the waves
As little archeocyathids grew into ocean forests.
Ancestors of fish and us,
The little squirts,
Swarmed the seas
Breeding in the Cambrian.
New life exploded on the scene
The trigger remained a mystery.
Shelled and soft creatures lurked in the water.
This was the hunting ground of Anamalocaris
The terror of the deep.
Claws that grasp
Beak that bites.
Even the kindly armored trilobite was no match for him.
The others nibbled and grazed on the bottom as Ottoia burrowed in the soft sand.
It dug around snatching poor creatures up when they wandered too close.
That was life in the Cambrian.
