Spiderweb Trapped in Amber

Awhile back I mentioned the discovery of a 120-115 million year old orb weaver trapped in amber. National Geographic and New Scientist both have a story on a spider web trapped in amber. The find dates to about 110 mya.

If you look closely you will notice there are some insects still entangled in the web! From New Scientist:

Palaeontologists who found the amber sliced it into three thin sections, revealing at least 26 silk strands, some interconnected. The web is not complete enough to be firmly identified as an orb web, with a spiral strand wound on radial spokes. But Grimaldi says the fragments are consistent with orb webs. “It’s a geometrically complex web, certainly not a random assortment of strands like a cobweb. It was certainly in one plane,” he told New Scientist.
