The Ediacaran saw creatures grow
Diversify as animals evolved.
But Cambrian descendants do not show
A lineage, preserved or else dissolved.
A missing fossil yearns to be dug up.
The flinders ranges burn to tell their tale
Trace fossils, both a spicule and a cup
Mean evolutionary theories can prevail.
Coronacollina was once a sponge
With opaline supports to hold it flat
Choia’s ancestor, before the plunge
Into the Cambrian destroyed the mat
On which it lived, before it then evolved.
Another fossil puzzle has been solved
