Question

Many marine organisms defend themselves from predators, using a dark ink-like pigment secreted from an inch-long sac attached to their epidermis. A fossil from the jurassic period, dated at almost 155 million years old and discovered in the wiltshire region, contains a perfectly-preserved ink-sac that was probably from a now-extinct species of squid, the belemnotheutis antiquus, whose exact origins has not been previously established. Therefore, this form of self-preservation in marine organisms is at least 155 million years old.
