Rivers of Time

Dinosaurs waiting for stone to erode,
their skeletons covered, uncovered again;
iron that's forgotten the blood where it flowed
and phosphorous leached from a primitive brain;

Delicate sabers of soft-stepping cats
enshrouded in shimmering oceans of sand;
Strata of relative sediment that's
concealing the bones of the earliest man.

Visible traces of numerous beasts;
the sum of Earth's creatures forever enshrined.
Signs of their passing won't slow in the least
the rivers and runnels of ongoing time.
