A lucky sperm meets egg in a shallow sea millions of years ago.
Or is it lucky egg?
Differentiation ... but not too much.
A larva drifting, cilia beating ...not too long though.
Transformation to benthic body.
A year or so of detritus sucking life.
Creeping, burrowing, avoiding.
Soft parts go first.
Mud oozes into spaces once tissue filled.
One, Two, Three ...? million years buried in limey mud.
Mud becomes rock.
The sea retreats.
Dynamite shatters limerock.
Excavating equipment rumbles.
Scoop, dump, transport.
Rock grinder groans and crushes.
Rock to gravel.
More scooping and dumping.
Front end loader spreads and grades.
Sifty sand road becomes stable gravel road.
Looks down and finds ...
a perfect fossil.
at the odds.
