In South Korea, found spiders the age of 110 million years with glowing eyes

В Южной Корее найдены пауки возрастом 110 млн лет со светящимися глазами

Experts from the University of Kansas has discovered the remains of a spiders age of 110 million years, eyes that still glowed in the dark. The find was made in South Korea, in the little-studied formation Jinju. About it researchers reported in an article in the journal of Systematic Palaeontology.

During excavations scientists have found fossils of ancient 10 spiders seven different types, but especially their attention was attracted by two of them — the eye of arthropods fossilized Mesozoic era still shone in the darkness.

This feature is related to the presence of tapetum lucidum — layer shell eyes that reflect light. The tapetum plays an important role in providing night vision. People have no tapetum lucidum, but many animals (for example, it is because of him the eyes of the cat glow in the dark) and some arthropods, crustaceans and fish.

The researchers note that this is the first known case of tapetum lucidum in the fossil remains of spiders. New types are called Koreamegops samsiki and Jinjumegops dalingwateri. Scientists believe that they occupied the same ecological niche that is now occupied by jumping spiders.
