Plate VII — Field Notes

Evidence Written in Stone

Observation precedes interpretation
Every specimen demands unhurried examination before the hand moves to annotate. The eye must learn the language of fossil form before the mind assigns meaning.
Chambers spiral with purpose, not accident
The logarithmic curve records growth itself — geometry as biography of the organism, each whorl a chapter of calcium and time.
Stratigraphy is narrative
Reading rock layers is reading the Earth's memoir — each stratum a compressed epoch, each unconformity a silence in the record.
Colour reveals what the eye overlooks
Iron oxides and mineral traces speak of temperatures and pressures long since passed — ochre and sienna are not decoration but diagnosis.
