Spider with a tail found preserved in amber

Scientists have identified a species of long-tailed proto-spider dating back over 100 million years.
For those terrified of spiders - be thankful that we still don't have these creatures running around.

Found in Myanmar within a piece of amber, this peculiar 'chimera' species is described as such because it appears to possess a combination of both primitive and modern body parts.

In addition to fangs, feelers and silk-producing spinnerets, this prehistoric creepy-crawly also possessed a long tail similar to those found in uraraneids - a type of ancient spider relative.

Scientists believe that the species, named Chimerarachne yingi, could actually be a missing link.

"It's a very primitive group and their relatives were present more than 250 million years ago," said Bo Wang from the Chinese Academy of Sciences in Nanjing.

"Maybe the tail originally had a sensory function; it is covered in short hairs, but when spiders changed to lifestyles like being sit-and-wait predators, the tail was no longer really needed and became lost."

Rather than being a "missing link" ancestral to spiders, Chimerarachne is actually a relict of an older group of arachnids. https://sci-hub.tw/https://www.nature.com/articles/s41559-017-0449-3

How long till they start cloning from it's preserved DNA?

Never, because there is no DNA preserved in amber inclusions.

I've heard of a movie called When Women Had Tails but this is ridiculous Kind of reminiscent of a vinegaroon.

Everything back then was HUGE because there was so much oxygen in the atmosphere. Plants, animals, bugs. Most life was much bigger back then.
