Thurandina

Thurandina is a genus of Devonian arthropod known from fossils found at Alken in Germany and first described by Leif Stormer in 1974. It belongs to the subphylum Chelicerata and is placed within the clade Euchelicerata, though its more precise classification remains uncertain, and it was once considered part of the order Eurypterida before that placement was abandoned. It is monotypic, containing only the type species, Thurandina waterstoni.
