Strabops

Strabops is a genus of strabopid, an extinct group of arthropods related to the aglaspidids, known from a single well preserved fossil found in the Potosi Dolomite of St. Francois County, Missouri and dated to the Furongian stage of the Late Cambrian, roughly 497 to 485 million years ago. At about 11 centimeters long it is the largest strabopid known, and its name, from Greek words meaning squinting face, refers to its distinctive inward turning eyes. Originally mistaken for a eurypterid, it was placed in its own order, Strabopida, in 1997, and its exact relationship to other early arthropods remains uncertain.
