Paleontologists reported today that they have discovered the largest fossil spider ever found.  Of course, that's a relative term since the 165 million year old arachnid had a body one inch wide with 2 and a half inch legs.  The spider was an early version of the Nephila family, more commonly known as a Golden Orb spider, which today uses its large netlike webs to capture birds and bats.  Most Nephilas today live in tropical climates, so it's safe to assume this prehistoric spider did the same.  Back in the Jurassic Era, there weren't any birds yet, but plenty of large flying insects must surely have served as airborne snacks for them.  The spider was found in volcanic ash in inner Mongolia.
