The spider's eyes glow even though they have died 110 million years ago
Korea has found long dead spiders stored in the rock. And for the joy of the scientists, the eyes of the arachnids are still reflecting – about 110 million years after the deaths of the beings. It is rare for insects and arachnids – which are much more fragile than boned sea creatures – to become fossilized in the rocks. But for yet unknown reasons, several of these spiders are fossilized, and the unique shape of their eye structures continues to reflect light – even in their petrified form. The reflective eye structure is called tapetum and is often used by creatures that hunt in the dark.
"So predators of night hunters tend to use this different eye," said Paul Selden, director of the Paleontology Institute at the Kansas University Institute of Biodiversity and the Natural Science Museum. "This is the first time the tapetum has found a fossil. This tapetum is a canoe-like little Canadian canoe.
spiders use the same eye structures for hunting, added Selden: How do the spiders become fossilized? Their fossilized bodies were found in a rock layer filled with fish and other marine creatures – but the spiders do not live in water
"It must be very special a situation in which they are or washed in a water body, "- They usually swim, but here they sank, and this kept them from decomposing bacteria – perhaps a state of low oxygen."
