Perplexicervix is a genus of perplexicervicid bird that lived during the Eocene epoch. Its affinities are uncertain but similarities with Otidiformes were noted in tentatively assigned postcranial remains.^[1]

Distribution

P. paucituberculata remains hail from the Walton Member of the London Clay Formation and date back to the Ypresian.^[1] P. microcephalon appears in the eleventh Mammal-Paleogene zone of Hessen, Germany, its fossils having been found in the Messel Formation.^[2]
