A fossil specimen discovered in 2000, initially celebrated as the earliest known octopus and dating back over 300 million years, is now undergoing significant re-evaluation. Recent analyses suggest that this ancient find, previously believed to be the world’s oldest octopus, might in fact be a partially decayed nautilus. This new interpretation casts doubt on its original identification and challenges our understanding of early cephalopod evolution, proposing that what was thought to be an octopus could merely be another type of ancient marine creature in a state of decomposition.
