Paleocene had a light tawny appearance and a semi sweet palate.
Eocene was the name of donkey in a play by Sophocles that became an eponym for stink.
Oligocene spreads well on karst and smells faintly of kerosene.
Miocene evokes memories of childhood, not to be confused with the madeleine cookie scene.
Pliocene has the scent of too much alcohol consumed in search of companionship as a cure for loneliness.
Pleistocene continues to occur wherever young children organize their own play. It is the scent of everything new with a foreshadowing of dissolution to come.
Holocene, being the present, is entirely artificially constructed and lacks in smell completely due to the triumph of cleansing technology. Whether this epoch will end completely sterilized remains to be seen.
