Paluxy Riverbed

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;
Multiple layers of 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 don't slow in the least,
The rivers and runnels of ongoing time.

I wrote this about a place in Texas where there are many fossils.
