The behavior may have evolved a little through the years but most of the idiosyncrasies that make them unique are still evident in the spiders of today.

Scientists have been able to take fossils and reconstruct these creatures to see exactly what prehistoric spiders looked like. These prehistoric spiders can be great help to find information concerning the time and place they lived in.
