DescriptionMegarachne servinei, was an Upper Carboniferous (Pennsylvanian) eurypterid, a group informally called "sea scorpions". It was originally described as a spider but in 2005, the fossil specimen was reexamined and determined to be a small eurypterid (information from Wikipedia.org).
This plaque is a replica of that arthropod.
