Woodwardopterus is a genus of prehistoric eurypterid, or sea scorpion, classified as part of the family Mycteroptidae.

[1] Originally classified as Eurypterus scabrosus, it was later found to be generically distinct and placed as a member of the family Mycteroptidae.

Later in 2005, was assigned to its own genus, and linked to a new own family, Woodwardopteridae inside Mycteropoidea, probably as a sister taxon of Megarachne.

[2][3] A possible second species, W. freemanorum, was named in 2021 and comes from the Changhsingian (Late Permian) beds of the Baralaba Coal Measures, Bowen Basin, central Queensland, Australia.

[6] It was named after Nick Freeman,[4] who discovered the large but incomplete fragment of the creature's cuticle about 12 cm (4.7 in) long[4] on his family property near Theodore in central Queensland in the 1990s.
