Mixopteridae is a family of extinct eurypterids found in Late Silurian marine strata.
Description
Mixopterids were characterized by large exoskeletons with scattered tubecules or semicircular scales. The prosoma (head) was subquadrate, protruding antemedially. The chelicerae (claws in front of the mouth) were small. The first two pairs of walking legs were strongly developed, with long paired spines. The third and fourth walking legs were moderately sized, with short spines. The preabdomen, the front portion of the body, was narrow with axial furrows, while the postabdomen was narrow. The telson was a curved spine.[2]
