Dolichopteridae is an extinct family of eurypterids that lived in the Silurian and Devonian periods.
Dolichopterid eurypterids had outer surfaces that were either smooth or with pustules and semilunar scales.
The compound eyes were arcuate and located anteriorly on the prosoma (head).
The telson (the posteriormost division of the body) was lanceolate.
The chelicerae were small, and the first three pairs of walking legs were stout, with powerful spines.
