Dolichopteridae is an extinct family of eurypterids that lived in the Silurian and Devonian periods.
Description
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 abdomens had epimers (lateral projections). The telson, (tail) was lanceolate. The chelicerae were small, and the first three pairs of walking lags were stout, with powerful spines. The last pair of walking lags had supplementary lobes, while the swimming lags had the last joint enlarged, as part of the paddle. The male genital appendage was long.[1]
