Lanarkopterus is a genus of prehistoric eurypterid with one recognised species, Lanarkopterus dolichoschelus. Lanarkopterus was long seen as a species of the closely related Mixopterus, though more complete specimens discovered in the 1960s determined that it differed in several aspects, enough to warrant a separate genus.
Specimens of the genus have been recovered from deposits of Late Silurian age in Scotland.
