Megarachne servinei
Hünicken, 1980

Megarachne servinei, the only species belonging to the genus Megarachne, was an Upper Carboniferous (Pennsylvanian) eurypterid found near Córdoba, Argentina.[2] It was originally described as a spider with a body length of 339 millimetres (13.3 in), which would have made it the largest spider ever to have existed.[2] In 2005, the fossil specimen was reexamined and determined to be a small eurypterid within the family Mycteroptidae rather than a spider.[2]
