The tendency for traits characteristic of old age to appear in younger individuals or organisms, or the attribution of elderly characteristics to younger things.
From Greek 'geron' (old man) + 'morphe' (form, shape) + '-ism' (condition or practice). A term from biology and anthropology describing precocious aging patterns.
Some animals naturally show geromorphism—juvenile axolotls look like miniature old salamanders with their wrinkled skin, which is why people find them so hauntingly ancient-looking.
