A brand new kind of spider which looks like a spider with a tail has been discovered in Myanmar.

The eight-legged creepy crawly is estimated to have sunk along the forest floors as far back as 100 million years ago.

Scientists found the creature trapped in a piece of amber from the mid-Cretaceous period, and now believe that it is an entirely new species.

The freaky discovery was made by an international team from the University of Kansas, and was published on Monday, Nature, Ecology & Evolution journal.

KU Paul Selden said: “There’s been a lot of amber is produced of northern Myanmar and the interest rate increased about ten years ago, when it was discovered this orange was for in the middle of the Chalk; therefore, all the insects found in it is much older than thought.”

“It is coming in China, where the dealers are selling to research institutions.”

The new creature looks like a spider, with common parts of the body including teeth and four legs that are used specifically for hiking.

But it is unique in that it is a “long flagellum, or tail”, that is not something found on a living spider.

Four new copies of this mysterious species, which is called Chimerarachne Yingi – have been found so far.

Their body measure approximately 2.5 millimeters, but their stories are even longer at about 3 millimeters.

The explain of the tail, Selden says: “A kind of flagelliform appendage tends to work like an antenna.”

“It is for the exploration of the environment. Animals that have a long whippy tail tend to be for sensory purposes.”

According to Selden, it is difficult to find out how the tailed spider spent his days, but there are a few clues.

“We can only speculate that, because it was trapped in amber, we take life on or around tree trunks.”

“Amber is fossilized resin, so for a spider to have caught it, it may well have been living under the bark or in the moss at the foot of a tree.”

However, We do know that the spider has spinnerets, that can be used for the production of silk.

But Selden says this does not mean that the old spider built and lived on the webs.

“Spinnerets are used for the production of silk but for a whole range of reasons – to be settled eggs to make dens to sleep in hammocks or just to leave trails.”

“If they live in burrows and they leave a trail so they can find their way back. All of these are designed for spinning made it up in the air and made insect traps.”

“Spiders took to the air when the insects took to the air. I suppose it is not make web sites that stretched across bushes.”

“However, like all spiders it would have been a carnivore, and would have eaten, insect eggs, I think.”

It is also possible that tailed spiders are not completely extinct, but they may not have discovered yet.

“We know a lot about the Burmese biota in the Cretaceous.”

“It was a pretty good tropical rainforest, and there are also a large number of other arachnids, we know were there, especially spiders, which are very similar to the ones you have today in the southeast Asian rainforest.”

“It makes us wonder if this is still alive today. We have not yet been found, but some of these forests are not as well studied, and it is only a small creature.”
