Rare Spider Fossil Preserves 100-Million-Year-Old Glowing Eyes

A new spider fossil discovery included a surprising find: remnant of reflective eye tissue.

Though common today, spiders don’t appear in the fossil record because of their soft bodies don’t preserve well, according to the paper of the Systematic Palaeontology. This is the first time a spider has been found in a fossil.

“It's the opening of the whole new world,” said Gizmodo, one of the paper's authors and directors at the University of Kansas. 19659004] A Korean high schooler and amateur fossil hunter named Kye-Soo Nam first found in the fossils in the 112-million-year old rocks called The Jinju Formation in South Korea. Fossils, Dinosaurs, Mollusks, Fish, and Dinosaurs, and Unidentified Fossil Spider Species

Some of the fossils came from the Lagonomegopidae spider family, the first time. But finding the spider preserved in stone, such as the reflective eye tissue.

The specimens showed "quite remarkable preservation" of canoe-shaped pieces of reflective tissue in the spiders' eyes, both apparently visible in the fossil itself and highlighted when the researchers analyze the chemical makeup of the fossil. They interpreted this reflective tissue as the wallpaper, but not humans.

You are wondering if you are looking for the best way to look at it. According to the paper, since the spider tapetum is formed from crystals of the molecule guanine, it would be more likely to be preserved than other soft tissues.

New fossil discovery adds more details to the story of life on Earth – a story that may never be complete . About the Old Spiders, it's pretty awesome to see the glow of 112-million-year-old spidey eyes.
