Ancient Life
Many rivers fed into the sea bringing leaves and driftwood from the land. These served as the base of the food chain. Bacteria and other microscopic scavengers ate the decaying wood. Plankton ate the bacteria. Clams filtered the small plankton. Snails ate the clams and were eaten in turn by crabs and fish. Mosasaurs and cephalopods ate the fish and crabs. Some organisms were swimmers or floaters, but most lived on or in the sandy mud of the sea bottom. This layer of sandy clay, bones, and shells became the Coon Creek Formation.

Famous quotes containing the words ancient and/or life:
“Silent rushes the swift Lord
Through ruined systems still restored,
Broadsowing, bleak and void to bless,
Plants with worlds the wilderness;
Waters with tears of ancient sorrow
Apples of Eden ripe to-morrow.
House and tenant go to ground,
Lost in God, in Godhead found.”
—Ralph Waldo Emerson (1803–1882)
“What life is best?
Courts are but only superficial schools
To dandle fools:
The rural parts are turned into a den
Of savage men:
And where ‘s a city from all vice so free,
But may be termed the worst of all the three?”
—Francis Bacon (1561–1626)
