Fine net spider made about 140 million years ago was found preserved in amber. Nets are found in Sussex, England, was preserved when the sap of resin before it hardens and wet stone. In the same stone was also found in the rest of the plant, insect droppings, and ancient microbes.
"This is a spider web of the oldest ever found by our fossil record," said researcher Martin Brasier of Oxford University, Saturday (31/10).
Brasier and colleagues using a computerized technique called confocal microscopy to reconstruct and examine the net and knot. Some things, including the nodes which are connected using a sticky fluid, indicates that the net was made by a spider that is related to spiders modern garden.
"This spider is also placed along the sticky nets to trap their prey," Brasier said. "The remains of the sticky liquid come preserved in amber.
The analysis of these nets also provide clues about the food of spiders. I think, based on web forms, this animal preys on flying insects such as flies and bees ancestors, wasps, and beetles, "Brasier said.
In 2006, the researchers found cobwebs are also preserved in amber. He was about 136 million years.
