Behold! New treasures from the Burgess Shale,
In black and silent strata long held firm.
From features soft, a bold ancestral tale …
Be proud, descendants of the noble worm!
Oh, glorious the hemichordate line,
Spartobranchus tenuis among them,
On slime and mud they heartily do dine;
History has surely under-sung them.
From which deep root, vertebral creatures grew?
A scarcity of fossils long obscured;
Into this question we can dive anew,
With gorgeous, detailed imprints that endured.
A wondrous time, the Cambrian Explosion …
Move over, Eve; my roots are in the ocean!
