l spiders of the largest prehistoric era of dinosaurs in a pile of ancient volcanic ash in Mongolia, Mainland China.The fossil was preserved during 165 million years so easily identified as adult female animals.
The spider, named Golden Orb Weaver or Nephila Jurassica were found buried in an ancient volcanic ash on the territory of Mongolia.
The fossil is the oldest species of giant spiders that live today, Nephila, which size is large enough to prey on birds and spiders. Similarly, as reported by Fox News on Thursday (04/21/2011).
The fossil has a body width 2.5 cm and 6.3 cm long legs, almost like a giant spider that exist today.
On the other hand, the male spider is expected to have a smaller body size.
The spider is an animal that is commonly found in tropical and subtropical regions.
Usually, female spiders weave webs would make yellow colored silk that will shine like gold when exposed to sunlight.
"We describe the discovery of the fossil As Objectionable largest spider in the world. A female Nephila Jurrasic era in the region from China, "said Professor Selden of the Paleontological Institute at the University of Kansas.
"These giant spiders may live in the woods adjacent to the lake," said Selden.
"Maybe there used to be the mountain near the location of fossil discoveries, is visible from the pile of ancient volcanic ash around the fossil findings," he added.
Scientists perform a microscopic examination to confirm the type of spider that has been 'petrified' together with fossil salamanders and water crustaceans.
Selden said this discovery could help our understanding of the evolution of spiders from dinosaur era to the present.
The scientists explain the full details of this discovery in the online journal Biology Letters.
