100 million-year-old spider with a tail found trapped in amber.

On Monday, two teams of scientists unveiled a "missing-linked" species of spider, which had a scorpion-like tail that was completely preserved in Amber in the jungles of Southeast Asia after at least 100 million years .
In a side-by-side published study in Nature ecology and development, one team argued that male sex organisms and silk thread-producing teats link the creature to live spiders.
The second team pointed to the tail and fragmentary body for a long time that Chimerachan Yingi is at least 380 million years old instead of the ancient and extinct lineage.
Either way, researchers believe that c. Yingy fills one hoarse in the evolutionary saga of approximately 50,000 species of traps and traps of spiders worldwide.
Bo Wang, a paleobiologist of the Chinese Academy of Sciences in Nanjing, said, "This is a missing link between the ancient Amarnaeda Order, which looks like spiders, but there are no spinheras making tail and silk, and there are modern spiders". In the study, c. Yingi suggests that his present-day, eight-legged cousins
Notably, previously unknown species were discovered simultaneously by two groups of scientists, each of which had detected two samples locked in transparent amber tidrops.
Incidentally, both teams presented their findings in the same magazine, which coordinated the joint release.
The total body length of approximately six millimeters (one fifth of an inch) - half raised by tail - c. Yingi, in fact, is an explosive spider.
Researchers estimate that the fibers created by the four nipples coming out from behind the abdomen were not likely to roam the trap, the researchers had speculated.
- Poison glands -
"Spintheres are used to make silk for whole reasons: to wrap eggs, make bad, go to sleep or leave behind bus trails," said Wang co-author Paul University professor Paul Celden. Kansas
C. Yingis are also called pimples-like appendas, pediplapses, which used to transfer sperm to the woman during intercourse, a signature symptom of all living spiders.
Wang told AFP that the tail or the flagellum, also known as Tulson, as its whip probably "worked as a sensory purpose"
On the contrary, modern spiders used silk to monitor the changes in their surroundings.
They have poisoned with special purpose glands, but none of the studies was able to confirm that Yingchi could poison its prey.
Both teams remotely disconnect their samples to use X-ray calculation tomography scanning technology
New species were discovered in the forest of Myanmar, which produce approximately 10 tonnes of amber each year.
"It is coming to China where dealers have sold to research institutes," Wang said.
Amber is important to find the earliest ancestors of spiders - but only to a certain point.
"The spiders have no soft body and no bones, so they do not fossil very well, so we rely on special conditions - especially Amber - to find them," Wang explained
But while working on time, marks of animals living in Amber end up 250 million years ago, making it difficult to detect the initial origin of the spider.
