Megarachne
From Wikipedia, the free encyclopedia

Megarachne servinei was a small Upper Carboniferous (Pennsylvanian) eurypterid found near C??rdoba, Argentina. Its leg span was 20 inches (50 cm). Originally, its fossils were thought in error to be a giant spider, the biggest spider that ever existed; that caused serious error in scripting the CGI television series Walking with Monsters. The series was already in production when Megarachne's true identity was discovered in 2004, and it was too late to correct the error. So, instead, the script was changed and the giant spider is simply referred to as "Mesothelae" instead. "Mesothelae" is actually a suborder of primitive spiders.
