Fossilised spider 'biggest on record' The female, which lived about 165 million years ago, belongs to a collection of spiders well known today - the golden orb weavers. Until this new fossil turned up in Inner Mongolia, the most ancient example from this grouping, or genus, was about 35 million years old.
