Spider web is 140 million years old

The tiny tangled threads of the worldâ€™s oldest spider web have been found encased in a prehistoric piece of amber, a British scientist said.
He also said the strands were linked to each other in the roughly circular pattern familiar to gardeners the world over.
â€śYou can match the details of the spiderâ€™s web with the spiderâ€™s web in my garden,â€ť Dr. Brasier said.
The web was found in a small piece of amber picked up by an amateur fossil-hunter scouring the beaches on Englandâ€™s south coast about two years ago, Brasier said.
A microscope revealed the existence of tiny threads about 1 millimeter (1/20th of an inch) long amid bits of burnt sap and fossilized vegetable matter.
While not as dramatic as a fully preserved net of spider silk, the minuscule strands show that spiders had been spinning circle-shaped webs well into prehistory, according to Simon Braddy, a University of Bristol paleobiologist uninvolved with the find.
â€śItâ€™s not a striking, perfect web,â€ť Dr. Braddy said. â€ś(But) this seems to confirm that spiders were building orb webs back in the early Cretaceousâ€ť â€” the geological term for the period of time between 145.5 and 65.5 million years ago when dinosaurs and small mammals shared the earth.
Spider experts believe that webs were developed even earlier, but the delicate gossamer threads rarely leave any trace. Amber, or fossilized tree resin, can occasionally conserve bits of web â€” an earlier find in Lebanon was dated to 130 million years ago, according to Brasier.
