The note of 'Fossil' unveils a profoundly dry, mineralic, and almost crystalline aroma, imbued with the immense stillness of eons. It does not project loudly but rather permeates with a solemn, ancient gravitas. Initially, it might present a subtle, chalky dustiness, reminiscent of weathered stone or sun-baked earth that has known millennia. As it evolves, deeper nuances emerge: a ghost of petrified wood, a cool, grey salinity akin to sea-worn rock, and a faint, almost metallic echo of deeply buried earth minerals. It possesses a rough, tactile dryness, never moist or verdant, but rather arid and venerable. This is a true base note, with minimal top or heart presence, offering extraordinary longevity and acting as a profound anchor, grounding more ephemeral notes in an olfactory bedrock. Its texture is like powdered ancient rock, offering a subtle, almost imperceptible diffusion that suggests vast, empty spaces and forgotten histories.
