Etymology
editProspectatrix 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
edit- P. genatenta occurs in the Lower Ordovician of the United Kingdom (Upper Tremadocian, Shumardia (Conophrys) salopiensis Zone, Shineton Shale, Shineton, Shropshire; Bergamia rushtoni biozone, Pontyfeni Formation, Whitland, Carmarthen District, Wales), Argentina (Tremadoc, Portezuelo de La Alumbrera Creek, Famatina Range, Upper Volcancito Formation, La Rioja).[3]
- P. exquisita has been found in the Lower Ordovician of northwest China (Dichelepyge sinensis Zone, upper Torsuqtagh Group northeastern Tarim, Xinjiang).
- P. brevior is known from the Lower Ordovician of the United Kingdom (Tremadocian, Skiddaw Group fauna, Lake District).
- P. superciliata (synonym Pricyclopyge superciliata)[4] from the Lower Ordovician of Turkey.
