A thread of 130 million years of spider is discovered in amber, in the area of Lebanon. The oldest thread in the world is four millimeters with small drops of tail coming from the spider glands.

This thread confirms the antiquity of adhesive silk. In fact, this finding is 90 million years older than the oldest adhesive spider thread known so far.

Scientists knew that the spiders of 410 million years ago had glands to produce silk, but they still don't know when they to form networks.
