}} Prospectatrix is a genus of trilobites of average size, that lived in the Lower Ordovician and is probably ancestral to the other genera of the Cyclopygidae family. Its eyes are only moderately enlarged and it has six or seven thorax segments. EtymologyProspectatrix is derived from the Latin, meaning “early observer”, expressing that this genus was an early representative of the extremely well-sighted cyclopygids. The species epithet is derived from the Latin exquisita, meaning excellent, refers to the well preserved type specimens. Distribution
